PVI-800 Navigation Control Panel

The PVI-800 works in parallel with the ABRIS navigation system, but whereas the ABRIS uses satellite navigation system inputs, the PVI-800 uses data from the Inertial Navigation Unit (INU).

2-43: PVI-800 panel

1. Upper display window

2. Lower display window

3. Keypad [0 – 9 + RALT]

4. “ППМ” (Waypoint mode) button. To select a waypoint from the flight plan, press this modal button (the button will light) and then press the button of the desired waypoint from the keypad. Upon selection, the waypoint will become the steerpoint. The PVI-800 can store up to the six waypoints. When in “ППМ” mode, the upper window will display the latitude coordinate and the lower window will display the longitude coordinate. The selected waypoint number will be displayed in the waypoint window. Note that waypoint steering information displayed on the HUD will be from the PVI-800 and not the ABRIS. [Q + RALT]

5. “ОР” (Reference point update) button. Used to select a reference point for an INU update. Up to four INU reference points can be set in the mission editor. [E + RALT].

6. “АЭР” (Airfield) button. This mode is used to select an airfield for RTB mode and it displays the coordinates of one of two airfields. In the simulation, airfield 1 will be your takeoff location and airfield 2 will be your landing location. If no landing or takeoff location is specified in the mission editor, this function will do nothing. [T + RALT]

7. “ОТ” (Target point) button. This mode is used to select a Target Point (TP) for ingress and entering coordinates for new TPs. Up to 10 TPs can be saved. TPs can be defined either as a fly over location, or with a Shkval lock. [U + RALT]

8. “ВВОД” (Enter) button. Used for the entering of data [I + RALT].

9. “φ/λ” (Own aircraft coordinates) button. Displays ownship coordinates. [A + RALT]

10. “Ψ:Z/T/Sпм” button. Indication of DTA (DH sub-mode) or XTE (DT sub-mode), time and distance to current waypoint in the Waypoint, Reference, Airfield, and Target navigation modes. [S + RALT]

DH sub-mode indication:

DT sub-mode indication:

11. PVI Master Mode selector can be rotated left [V + RALT] and right [B + RALT]:

o “ОТКЛ” = Powers the PVI-800 off.

o “КВД” = Verification of entered data. This mode allows you to check a waypoint‟s coordinate and other data without changing the active navigation mode or steerpoint.

o “ВВОД” = Edit waypoint. This function allows you to enter waypoint coordinates, wind conditions, and other data. To do so:

 Select EDIT

 Press “ППМ” and the small upper window will display the total number of waypoints currently stored.

 Press 1 – 6 on the keypad to select the desired waypoint number and the current waypoint coordinates will be displayed.

 Using the keypad, enter new coordinates for the selected waypoint. Note that you should indicate N/S or E/W prior to entering the coordinate. To make the coordinate positive, press the 0 key first; to make the coordinate negative, press the 1 key first. When set to negative, a “-“ symbol will appear left of the coordinate.

 After the coordinate has been entered, press the ENTER button. Or, you may press CANCEL to clear the data on the display.

o “РАБ” = OPER (normal operation)

o “ИМП” = Simulated flight. This mode will simulate the entered flight plan with a simulated ground speed of 1,000 km/h. This can be used to check all bearings, ranges, tracks, and other data prior to flight.

o “К-1”, “К-2” = Non-functional programming modes.

12. Waypoint display

13. Airfield number, fixed point, target point, or correction point display.

14. “ПЗ” (Rerun) button. Inertial navigation unit (INU) for in-flight realignment. No function.

15. “ТВ” (Precise alignment) button. INU precise alignment. This will align the INS gyrocompass and provide the most precise alignment with the heading finding function. This alignment takes about 30 minutes to complete. [R + RALT]

16. “НВ” (Normal alignment) button. INU normal alignment. [Y + RALT]

17. “СБРОС” (Reset) button. Press this button to remove data entered when in EDIT mode. [O + RALT]

18. “КС” (Initial point coordinates) button. Pressing this button will display your initial coordinate point and allow you to enter a new one. By default, the initial point coordinate comes from the mission editor. In this case, the initial point (КС) and own aircraft (“φ/λ”) coordinates will similar. [P + RALT]

19. “Ψи/T/Sкм” (True heading/time/distance) button. Indication of true heading, time, and distance to final waypoint in the Waypoint, reference, airfield, and target modes. [F + RALT]

20. “Ац/Дц” (Heading/range to target point) button. Indication of heading and range to target in the Ingress mode. [G + RALT]

21. “δ/V” (Wind direction/speed) button. Indication of the wind direction and wind speed. Used meteo wind direction (from) that differs on the 180° degrees from navigation wind (to). [D + RALT]

22. “И-251В - ПРОЛ” (I-251V Shkval – Fly over INU update) switch. Mode of operation for INU correction. When set to "И-251В", INU coordinates will be corrected using the Shkval optics. When set to "ПРОЛ", the coordinates will be corrected by over-flying a reference point. [V + RCTRL]

23. “ЯРКОСТЬ” (Brightness) knob. Adjust panel backlighting brightness. Increase brightness [P + RSHIFT + RCTRL]] and decrease brightness [[P + RSHIFT + RALT]].

24. “ВЦУ - ОТКЛ” (Data link – Off) switch. Off-board targeting data link power ON-OFF, respectively. [B + RCTRL]

PVI navigation indication form

PVTz-800 Off-Board Targeting Data Link Mode Panel

This panel is located directly below the PVI-800 navigation control panel described above. The function of the PVTz-800 is to manage ownship data link identification and send-receive mode.

2-44: PVTz-800 off-board targeting data link mode panel

The PVTz-800 data link panel allows you to set your data link identification number and the manner in which you send and receive information with your flight members over the data link (maximum of four aircraft per data link group). Please reference the ABRIS section of this manual to learn how data link information is visually presented to you. In a multiplayer mission, it is possible to have multiple data link groups in the mission at the same time; however, each would have to be on a different frequency. The data link panel consists of two dials, the "КТО Я" dial and the "РЕЖИМ" dial. The "КТО Я" (my ID number) dial, can be set 1 through 4 and allows you to set your own data link identification number. Each flight member should be assigned a unique ID number and the flight leader should be assigned ID 1. [I + LCTRL] The “РЕЖИМ" (data mode) dial, allows you to select one of four options regarding how you receive and pass data link information to the rest of your flight. [M + LCTRL] The options include:

1. "ОТКЛ" (Disable) disables data link communication with your flight.

2. "ПРИЕМ" (Receive) is a receive data only mode (you cannot send data) and it is a secure mode that is difficult to detect by enemy electronic emission detection systems.

3. "ВЕДОМ" (Wingman) mode allows you to send and receive information from other flight members including the flight lead (ID 1). Wingman icons will be displayed on the ABRIS.

4. "КОМ" (Commander) mode allows you to send and receive information from Jjust the flight leader. Wingman icons will be displayed on the ABRIS.

For more information about sending and receiving data link information, please consult the earlier PRT Data Link Control Panel chapter in this manual.
