Welcome Thank you for choosing the Ryan Multi-Hazard Display (MHD) using the Honeywell EGPWS. This Operating Handbook is intended as a guide to the capabilities and operation of the Ryan MHD/Honeywell EGPWS system. This manual will help you get the best performance from your system. Refer to this handbook for the Ryan MHD/ Honeywell EGPWS limitations. Refer to the Ryan Multi-Hazard Display Pilot Operating Handbook - General Information for general information about the MHD. This manual should be used with the Honeywell EGPWS Pilot s Guide. Refer to the Honeywell EGPWS Pilot s Guide for information about operating and interpreting the Honeywell EGPWS information. 6 CHAPTER 1

7 TSO Information The Ryan MHD Honeywell EGPWS application software for the MHD was developed to the requirements of DO-178B level D. The Ryan MHD complies with the requirements of TSO-C113, Airborne Multipurpose Electronic Displays. The conditions and tests required for TSO approval of the Ryan MHD are minimum performance standards. It is the responsibility of those installing the Ryan MHD either on or within a specific type or class of aircraft to determine that the aircraft installation conditions are within certification standards. The Ryan MHD may be installed only if the installation is performed in accordance with 14 CFR Part 43 or the applicable airworthiness regulations. CAUTION: The Honeywell EGPWS audible warnings, the associated controls, and annunciators constitute a complete EGPWS system. The Ryan MHD is a supplemental display, and is secondary with regard to indications from the EGPWS system. Polarized Sunglasses The liquid crystal display is not compatible with polarized sunglasses. General Information 7

8 Conventions Used in this Manual Italics are used to identify the mechanical controls. Bold is used to denote a menu item, which can be activated with a Soft Key. CAPITALS are used to identify the screen labels of the four unlabeled pushbuttons beneath the LCD screen. These push buttons access menus or dialogs. The MENU and SEL keys to the right of the LCD screen are also capitalized. Quotation marks are used to highlight specific wording as it appears on the LCD screen. The location of a particular menu or dialog is specified as a sequence of buttons, menus and dialogs separated with /. This is called the path to the menu or dialog. For example, relative terrain can be viewed in all directions about the aircraft with the path MENU/Quick/Center. This path indicates that you would press the MENU button, and then the Soft Key labeled Quick, and then the Soft Key labeled Center. A knob can be rotated and pushed. A button can be pushed or held. A Menu is a set of options displayed at the bottom of the screen that indicates the current function of each Soft Key. Each menu also has a title that is displayed to show the functional grouping of its options. When a menu is displayed, the system is said to be in Menu Mode. 8 CHAPTER 1

9 CHAPTER 2 Fast Start

10 The operation of the MHD is generally intuitive and there is more than one way to access many functions. The following is an overview of the operation of the MHD with the EGPWS Application. Turn the unit on by pressing the VIEW/BRT knob (Left Rotary knob). Turn the unit off by pressing and holding the VIEW/BRT knob. Twist the VIEW/BRT knob to adjust display brightness (The cockpit dimmer controls knob brightness). Press the VIEW/BRT knob to select either Single or Multi- View mode. The Multi-View mode shows the primary application and two thumbnail images of other applications. If the system consists of only one application, the thumbnail images are blank. Press the SEL button to rotate through the applications. When the EGPWS application is selected, the terrain icon shows in the upper left corner of the display. Twist the DATA/RNG knob (Right Rotary Knob) to adjust the range when EGPWS is the Primary Application. The current display range is shown in the upper-right corner. This value corresponds to the distance between the host aircraft symbol and the range ring on the display. Pressing any Soft Key button will access the EGPWS - Quick Menu, which can be used to change to change the display offset format of the terrain data. The Center selection shows terrain 360 around the aircraft; the Rear selection places the aircraft symbol at the bottom (or rear) of the display for a look-ahead view. Press MENU to provide access to display configuration options. The menus for these functions will appear above the Soft Key buttons. See figure 5.3 for a diagram of the complete EGPWS application menu structure. Terrain and obstacle height relative to the aircraft is depicted using colors and shading. In general, textured red means the 10 CHAPTER 2

11 terrain depicted is far above your aircraft; textured yellow means the terrain is at the same height or above; green means the terrain is below your aircraft and black represents terrain and obstacles that are far below. See Figure 2.1. Terrain or obstacles causing a caution condition are depicted in solid yellow ( ) while warning conditions are depicted in solid red ( ). When all terrain shown on the display is below your aircraft, the EGPWS reverts to its peaks display mode. In peaks mode, the EGPWS uses shades of green to identify nearby peaks or obstacles, solid green ( ) representing the highest peaks. The upper and lower elevation values (displayed in the lower right corner) can be used to determine the elevation of the terrain and obstacles being displayed. NOTE: The exact color representation for terrain and obstacle height depends on the specific model of EGPWS installed. See the Honeywell EGPWS Pilot s Guide for a complete discussion on the use of color to depict relative terrain. FIGURE 2.1 Textured color depicts terrain and obstacle height Fast Start 11

13 CHAPTER 3 Basic Operation

14 Product Description The Ryan Multi-Hazard Display (MHD) consists of a rugged highresolution Active Matrix Liquid Crystal Display (AMLCD) with anti-glare lens, Light Emitting Diode (LED) backlit optical rotary knobs, and tactile electroluminescent (EL) pushbuttons. The MHD receives inputs from the pilot and provides visual and tactile feedback. Refer to Figure 3.1and Figure 3.2 below. FIGURE 3.1 Multi-Hazard Display, Illustrating the Instrument Panel Mounting Arrangement FIGURE 3.2 The MHD Controls 14 CHAPTER 3

15 The MHD serves as a common location to display aviation hazards while reducing clutter on navigation displays. Many hazards are better viewed at ranges that differ from those preferred on moving map displays. Surrounding terrain, for instance, is optimally viewed at less than twenty miles. Traffic is best viewed at five to ten miles. Satellite and lightning weather is normally viewed at two hundred miles or more. Thus, when hazard information is overlaid on a navigation map, an optimal range setting is impossible for all data, and vital information may be so cluttered so as to reduce effective communication to the pilot. The Ryan MHD presents each hazard individually, allowing the flight crew to optimize the range of each application while minimizing the space used to display them. The MHD EGPWS Application communicates with an external EGPWS processor (such as the Honeywell KGP-560) to display the terrain generated by the processor. Multiple hazard information can be displayed on the equipment individually (the Single-View mode) or three at a time (the Multi-view mode) using the large primary application display and two thumbnail views. The system is designed to operate with minimal pilot interaction. CAUTION: The Ryan MHD EGPWS Application displays information provided by the installed Honeywell EGPWS. The Honeywell EGPWS Pilot s Guide and other official publications are the primary guides for operation of the equipment. Information in this manual is not intended to supersede any information, cautions, or warnings found in current EGPWS documents. Field loadable software updates allow additional applications to be added without the need to return the MHD to the factory. The MHD accepts data via the standard ARINC 429 aviation data bus and other RS-232 protocols to interface with current and future hazard sensors. Fast Start 15

16 Startup The MHD turns on automatically with the avionics master switch, or with a press of the Left Rotary knob (the VIEW button/brt knob). It may take 20 seconds or more to display an image. At low temperatures, the startup time may be slightly longer. If the system appears to have not turned on, check the brightness setting of the display by turning the Left Rotary knob clockwise. Press and hold the same button to turn the unit off. Display Brightness The brightness of the display may be adjusted using the Left Rotary knob labeled BRT. Control Backlighting The pushbuttons and rotary knobs are backlit. The intensity of the control backlighting can be adjusted using the panel dimmer controls in the cockpit (if connected during installation). The buttons use reflective technology for daytime viewing and active backlighting for nighttime. By design, the backlighting is very dim and appears to change very little when adjusting with the panel dimmer, especially compared to the knobs. Controls The following table summarizes the control functions of the display with the EGPWS Application. Refer to Figure 3.2 for an image of the MHD with the controls labeled. Refer to the Multi-Hazard Display Pilot Operating Handbook - General Information for a more detailed description of the MHD basic controls. The operation of the unit is designed to be intuitive, with quick access to the most used functions. To aid in the intuitive operation it is possible to accomplish some functions in more than one way. Use this guide with the display in order to understand the operation and explore all the functions. The following table defines the function of each control in the EGPWS application. Once the process is understood it will normally not be necessary to refer to this table for operation. 16 CHAPTER 3

17 Button (and Action) Left Rotary Knob (twist) Left Rotary Knob (momentary press) Left Rotary Knob (press for 6-10 seconds) Right Rotary Knob (press) Right Rotary Knob (twist) SEL, Multi-view Mode (press) SEL, Single-View Mode (press) MENU (press) Function in the EGPWS Application Adjusts brightness of the LCD Selects Single-View or Multi-View. Pressing the button when a dialog is displayed saves and exits the dialog. When the MHD is turned off, pressing this knob will turn it on. Turns the MHD off. Clears the menus from the display when they are being presented. Otherwise, pressing the knob has no effect during normal operation. Changes the display range for the terrain data. Rotates the applications from the main display to the thumbnail displays. When only one application is installed, the thumbnail other windows are blank. Rotates the applications from the main display to the background (that is, operating but not displayed). When only one application is installed, the SEL button has no apparent function in the Single-View mode. When not in menu mode, this button invokes the menu for the primary application. When in menu mode, this button causes the next higher menu in the menu hierarchy to be display. If a Soft Key button is mistakenly pressed, the MENU button allows the user to go back to the previous selection. Fast Start 17

18 Button (and Action) Soft Key (press) (automatic, or pop up ) Function in the EGPWS Application When not in menu mode, the Soft Keys invoke the quick menu for the primary application. When in menu mode, pressing a Soft Key activates the corresponding menu option shown on the screen just above the Soft Key. Terrain Caution and Warning The EGPWS caution and warning functions are prioritized on the MHD. If the MHD is displaying any other application when a terrain warning or caution occurs, a Single- View screen of the EGPWS is displayed. The Traffic application has a similar function. The EGPWS also has priority over the traffic application. See Figure CAUTION: The EGPWS application must be operating in order to provide warnings. To verify the EGPWS display application is available, view the EGPWS application in either the Single-View or Multi-View mode. NOTE: For appropriate indications on the MHD, the EGPWS application must be operating and available to be selected for display, but it does not need to be in view. Single-View and Multi-View Modes There are two basic display modes: Single-View and Multi-View. The Single-View mode displays only one application, such as EGPWS terrain. While in the Single-View mode, different applications are selected sequentially using the SEL button. The Multi-View mode can show up to three applications at once. The Primary Application is in the large display area, and two secondary applications are presented in small thumbnail displays. 18 CHAPTER 3

19 Pressing the SEL button while in Multi-View mode will rotate application positions clockwise. Each press of the SEL button moves the secondary application in the upper thumbnail onto the main screen, making it the primary application. See Figure 3.4. Press the left rotary knob to switch between the Single-View and Multi-View modes. Detailed information about the Operator controls is found in the Multi-Hazard Display Pilot Operating Handbook - General Information. Figure 3.3 and Figure 3.4 below show the Single-View mode and Multi-View mode. In Single-View mode, the entire screen is dedicated to a single application (EGPWS, in this instance). In the example shown, the aircraft is flying along a narrow valley with terrain on each side that is at or above the aircraft height. Ahead, the valley bends to the left and its floor appears to be climbing. FIGURE 3.3 Single-View Mode In the Multi-View mode (Figure 3.4), the screen is divided into sections displaying three different applications. In the example, EGPWS is the primary application. Weather and traffic are the secondary applications displayed in the thumbnail views. The arrows in Figure 3.4 show the rotation sequence that occurs when the SEL button is pressed. Figure 3.5 shows the EGPWS application displayed in the Multi-View thumbnail. Fast Start 19

21 CHAPTER 4 EGPWS Display

22 Application Identification The terrain icon in the upper-left corner of the display region identifies the displayed data as terrain. The Ryan MHD is designed to support a variety of terrain interfaces. All of the terrain applications, including the EGPWS application, are identified with the terrain icon. EGPWS Status During normal operation of the EGPWS processor, the EGPWS display includes the abbreviation TERR in the upper left corner as shown in Figure 3.3. Its color is dependent on the current status; green when there is no warning, yellow during a caution, and red during a warning. Figure 4.1 shows the EGPWS status word during a caution condition. If the warning or caution is due to an obstacle rather than terrain, then OBST is presented in the appropriate color as shown in Figure 3.6. When the EGPWS processor reports a problem it is annunciated with a yellow message such as INOP (inoperative) or NAVAIL (not available), and the terrain depiction is removed from the display as shown in Figure 4.3. FIGURE 4.1 Terrain display during a caution condition FIGURE 4.2 Warning condition issued for an obstacle 22 CHAPTER 4

23 FIGURE 4.3 EGPWS reporting that it is inoperative Host Aircraft Symbol The host aircraft is depicted using a white aircraft symbol. The preferred shape of the host symbol can be selected in the Host Symbol dialog, accessible via the System Menu. Helicopters or fixed wing aircraft can be selected. To get to the host symbol dialog press MENU/MENU/System/Prefs/Hosts. See CHAPTER 5 for more details about the System Menu structure. When your heading or track cannot be determined by the EGPWS, the EGPWS display will revert to a North-up orientation. When this happens, the host aircraft symbol is replaced with a non-directional symbol indicating terrain is no longer referenced to the host aircraft heading or track. See Display Reference (pg. 25) for further discussion on the North-up presentation. Host Aircraft Offset The host aircraft offset allows the terrain data to be presented in one of several different display formats. The Center offset selection places the aircraft symbol near the center of the display to show the terrain 360 around the aircraft. The symbol is offset slightly toward the bottom of the display to provide the best view in the forward direction. See Figure 4.4. CAUTION: The EGPWS processor may take 20 seconds or more to reformat the display as a result of a change to the host offset. The host offset should only be changed when the current situation allows time for the display format to be updated. EGPWS Display 23

24 The Rear offset selection places the aircraft symbol at the bottom (or rear) of the display providing the best view in the forward direction. See Figure 4.5. The position of the host symbol can be switched using the Quick menu or via the MENU/Config/Offset menu. The host symbol offset selection will apply to all view modes (Single-View and Multi-View, including the thumbnail) FIGURE 4.4 Terrain depicted using the Center offset. FIGURE 4.5 Terrain depicted using the Rear offset. Display Range When the EGPWS is the Primary Application, the current display range is shown in the upper-right corner. This value corresponds to the distance between the host aircraft symbol and the range ring on the display. The display range is shown in all view formats including the thumbnail. The display range is adjusted by rotating the Right Rotary knob. Ranges of 1, 2.5, 5, 10, 20, 40, 80, 160 and 320 nm are available. During range adjustments, the terrain image is cleared and the range 24 CHAPTER 4

25 label is momentarily duplicated on the left side of the outer range ring (See Figure 4.6). The duplicate range label is provided for convenience, since the user's hand may obstruct the view of the upper right corner of the LCD screen while the Right Rotary knob is used. FIGURE 4.6 Example of the momentary duplicate range label shown while adjusting the range. When the EGPWS Application is displayed in a thumbnail region in Multi-View mode, the display range is shown at the top right of the thumbnail. The display range of a thumbnail application cannot be adjusted using the Right Rotary knob. To adjust the range, press the SEL button to rotate the EGPWS application to primary. Alternatively, use the EGPWS - Display Range menu by pressing MENU/MENU/EGPWS/Config/Range. The menu provides a limited display range selection of 5, 10, 20, and 40 nmi. Display Reference The display reference determines how terrain is displayed relative to the host aircraft symbol. Normally, the display is referenced to the heading of the aircraft or, if heading is not available, to the aircraft s ground track. The display reference is indicated at the top of the display as shown in Figure 4.4 and Figure 4.5 above. In this case, the display is referenced to aircraft true heading with a heading direction of 120. When heading is not available, and ground track cannot be determined, the display reverts to a North-up display reference. In this case, the host aircraft symbol is presented as a nondirectional symbol as shown in Figure 4.7, and the display will be labeled NORTH. Once aircraft ground track is established, the display will revert to the normal track reference. EGPWS Display 25

26 The display reference is normally only shown on the Single-View screen view. The exception to this is when the display reference is North-up. The North-up display reference is also shown on the Multi-View main screen. FIGURE 4.7 Example of the display in a North- Up depiction. Geometric Altitude The calculated geometric altitude, expressed in feet rounded to the nearest 100 feet, is placed in the lower left corner of the terrain map. This value is calculated based on GPS position, altimeter input, and outside air temperature. It represents the altitude being used by the EGPWS in its relative terrain clearance calculations. The geometric altitude is presented on the Single-View screen and Multi-View main screen. It is not presented on the thumbnail. Depending on how your system was configured during installation, geometric altitude will be identified with the label MSL or GSL (the value itself is the same, just the label is different) CAUTION: Geometric altitude is presented for reference only. It is not suitable for navigation and should not be used as a replacement for an approved altimeter. Refer to the Honeywell EGPWS Pilot s Guide for information regarding geometric altitude. Upper and Lower Elevation Values The upper and lower elevation values are presented in the lower right corner of the terrain map. They are not presented in the thumbnail view. The top number is the upper elevation value, representing the 26 CHAPTER 4

27 highest peak level in the display area. The bottom value is the lower elevation value and it represents the lowest altitude terrain depicted (other than black) in the display area. Both values are presented in feet, msl. The colors of the elevation values correspond to the color representation of the terrain associated with it as shown in Figure Terrain Presentation The EGPWS processor depicts terrain using colors and textures. It operates in one of two modes, depending on your aircraft height relative to the surrounding terrain. The transition between the Relative mode and the Peaks mode is performed automatically by the EGPWS processor without pilot intervention. NOTE: The exact color representation for terrain and obstacle height depends on the specific model of EGPWS installed. See the EGPWS Pilot s Guide for a complete discussion on the use of colors and textures to depict terrain. Relative Display Mode The Relative display mode is used when terrain or obstacles within the selected display range are at or above your height. In this mode, colors and textures represent the elevation of nearby terrain relative to your altitude. See Figure 4.8. FIGURE 4.8 Relative display mode EGPWS Display 27

28 Peaks Display Mode The EGPWS processor transitions to the Peaks display mode when all terrain and obstacles are well below your aircraft. In this mode, green textures are used to present nearby high points, or peaks, even though they may be far below. See Figure 4.9. The elevation values (lower left corner) can be used to determine the maximum elevation of the surrounding terrain. FIGURE 4.9 Peaks display mode Display Colors and Textures The EGPWS Pilot s Guide describes the use of colors and textures to represent various terrain heights for the two display modes. Figure 4.10 shows how Ryan s EGPWS application presents the colors and textures used by the EGPWS processor. 28 CHAPTER 4

29 50% Red Terrain and/or Obstacle far above your altitude. 50% Yellow Terrain and/or Obstacle at or above your altitude. 25% Yellow 50% Green Terrain and/or Obstacle below your altitude. FIGURE 4.10 Presentation of terrain and obstacles using colors and textures (See EGPWS Pilot s Guide) 16% Green Black 16% Blue Magenta Dots 100 % Red 100% Yellow 100% Green Terrain and Obstacles far below your altitude. Water at sea level Unknown terrain, no terrain in database Terrain and/or Obstacle generating a Warning condition Terrain and/or Obstacle generating a Caution condition Peaks of Terrain and/or Obstacles, when operating in Peaks mode. Caution and Warning Conditions When the EGPWS issues an aural and visual caution or warning, the terrain causing the caution or warning condition is presented on the display as solid yellow or red respectively (see Figure 4.11 and Figure 4.12). The display will automatically go to a pre-selected range that depends on your specific model of EGPWS processor and how it is configured. Refer to your EGPWS Pilot s Guide for more information on how caution and warning conditions are presented. EGPWS Display 29

30 CAUTION: The Honeywell EGPWS audible warnings, the associated controls, and annunciators constitute a complete EGPWS system. The Ryan MHD is a supplemental display, and is secondary with regard to indications from the EGPWS system. When the EGPWS application is not being viewed on either the Single-View screen or the Multi-View main screen, it will pop-up to the Single-View presentation. Once the warning or caution is presented on the display, the display range can be changed or other other applications can be viewed. Any new caution or warning condition will again pop -up to the EGPWS display at the preselected display range. When a Traffic Advisory System (TAS) or TCAS I is installed, terrain cautions and warnings take precedence over Traffic Alerts. Traffic Alerts (TA s) are added as a text field along the bottom of terrain caution and warning displays (see Figure 4.13). If a terrain caution or warning and a TA is present, and another application is selected, the display will pop-up to the Traffic Alert. See Multi- Hazard Display Pilot Operating Handbook - Traffic Application for information about Traffic Alerts. FIGURE 4.11 Terrain ahead causing a caution condition 30 CHAPTER 4

31 FIGURE 4.12 Terrain ahead causing a warning condition FIGURE 4.13 Simultaneous Traffic Alert and terrain warning EGPWS Processor Failure When the EGPWS display application powers up and detects that the EGPWS processor is not communicating, it displays a No EGPWS Data message across the screen and no terrain data will be displayed. See Figure If communication had been established and then lost, the message will read EGPWS Link Lost and terrain data will not be displayed. These messages are displayed on both the Single-View screen and Multi-View main screen. In the thumbnail view, the message reads No Data. See the Appendices for a complete list of failure mesaages. FIGURE 4.14 EGPWS processor is not communicating EGPWS Display 31

32 Check Altimeter Warning Some models of EGPWS processor support monitoring of the aircraft s encoding altimeter. When the processor determines there is a large discrepancy between the encoding altimeter input and that computed from GPS, a ChkAlt indication is added to the display as shown in Figure The ChkAlt indication can be viewed in all display formats including the thumbnail. The criteria by which it is activated are described in the EGPWS Pilot s Guide. FIGURE 4.15 Example of a possible altimeter problem 32 CHAPTER 4

33 CHAPTER 5 Menus and Controls

34 Menu Basics Menus on the Ryan MHD appear at the bottom of the display as a bar of button labels above the four Soft Keys. The menu bar consists of a menu title on top and four button labels on the bottom (see Figure 5.1 below for an example). The Soft Keys are identified from left to right as SoftKey1, SoftKey2, SoftKey3, and SoftKey4 (see Figure 3.2). NOTE: Figure 5.3 and Figure 5.4 illustrate the menu structure. FIGURE 5.1 Accessing the EGPWS application menu During normal operation the menus are hidden to maximize the screen area for useful data. There are two methods to access the menu bar. Press the MENU button - This will take you to the top-level menu for the primary application (See Figure 5.1). Press a Soft Key - This will take you directly to the Quick Menu for the primary application (See Figure 5.2 below). The Main Menu is the top-most menu in the menu hierarchy. Access the Main Menu by pressing the MENU button twice. The first press brings up the menu for the primary application, and the second press selects the Main Menu. The system menu and the menus for all applications can be accessed from the Main Menu. 34 CHAPTER 5

35 OPERATING TIP: When a menu is displayed, pressing the MENU button will return you to the menu that is directly above the current menu. This is a convenient way of backing up if the wrong menu is inadvertently selected. FIGURE 5.2 Quick Menu Selections for the EGPWS Application The Main Menu Since the Main Menu is the top-most menu, the MENU button is used to access additional pages of buttons associated with the Main Menu. For example, if there were four applications active in the MHD there would be five items on the Main Menu, One for each of the four application menus, and one for the System Menu. Since there are only four Soft Keys, there would be two pages of button labels on the Main Menu. The MENU button would allow you to navigate between these two pages. The Quick Menu The concept of the Quick Menu is to provide a method for a pilot to immediately access the most frequently used functions. Since any one of the four Soft Keys will bring up the Quick Menu, this menu can be accessed with a single button press. Once familiar with the items on the Quick Menu, the Quick Menu functions of the primary application can be accessed simply by pressing the associated Soft Key twice. The first press will bring up the quick menu, and the second press will select the associated function. For instance, to select the Center host offset, simply press SoftKey1 twice. The first press brings up the EGPWS - Quick Menu, and the second press selects Center from the Quick Menu. See Figure 5.2 above. Menus and Controls 35

36 The EGPWS Application Menu The EGPWS Menu allows control over the display format of terrain data. A graphical depiction of the menu structure is shown in Figure 5.3 below. A short description of each menu item follows. System Main Menu TAWS Config EGPWS Menu Quick EGPWS - Configuration Offset Range GeoAlt..

37 EGPWS - Quick Menu (same as EGPWS - Host Offset) EGPWS - Host Offset Center Sets the display of the EGPWS Application so that the host symbol is placed near the center of the window, allowing 360 of viewing (with slightly enhanced look ahead viewing) Rear Sets the display of the EGPWS Application so that the host is offset to bottom (rear) of the display, providing a forward looking view. EGPWS - Display Range 5, 10, 20, This is the same as changing range with the Right Rotary 40 nm Knob except that the range selections are limited to four. The System Menu Figure 5.4 shows the system menu structure. More detailed information can be found in the Ryan Multi-Hazard Display Pilot Operating Handbook - General Information.
