F/A-18A/B HUD Camera

  The F/A-18A/B, Head Up Display (HUD) camera is a new configuration operating on the Lot XII and lower series F-18s.  
  Part Number  93 - 2040 - 501            NSN  5821-01-662-2657             MX-10403A/AXQ  
  Part Number  93 - 2040 - 502            NSN 5821-01-662-2666              MX-10403B/AXQ  
  The input connector to the camera utilizes the same connector type and the same pin function as the legacy camera.
The body of the camera is the same size and utilizes the same mechanical mounting provisions used on the legacy 
The GO indicator lamp is Night Vision Goggle (NVG) compatible.
The camera looks into the HUD-combining glasses and accurately records the HUD symbology and outside world,  
   permitting accurate recording of “what the pilot saw.”
The new camera has been flown by the US Navy and the following enhanced features were noted:
            ◊ Better color and higher resolution
            ◊ FOV extended coverage including recording of all the azimuth heading numerics and the complete roll angle 
               information in the Navigation mode.
            ◊ Intended low-light level coverage including night recording
            ◊ Two Built-In Test (BIT) features

  Vibration (non-gunfire) random/sine low frequency region V-FF-3. Perform vibration. Equipment was operating and
   monitored during testing.
Vibration (gunfire) sine test schedule (total time each axis – 150 min)
Vibration (gunfire) sine test levels. Perform sine vibration. Total time in each axis was 150 minutes.
Vibration (non-gunfire) random test levels. Perform endurance levels 120 minutes each axis. Equipment was  
   operating and monitored during testing.
Service shock (longitudinal, vertical and lateral). Perform 6 total shocks, 3 in each direction for each test.
   Figure 4-3.2: Service shock test requirements / Shock response spectrum region S-FF-2.
Crash safety (Perform crash safety per Fig 4-5). Crash test requirements. All shock regions.
Thermal non-operating thermal cycling: -57°C. Dwell for a period of 2 hrs. Raise the temperature to +125°C
   and dwell for 16 hrs.
Operating thermal cycling: -40°C. Dwell for a period of 2 hrs. Raise the temperature to +71°C and dwell for 16 hrs. 
   Raise the chamber temperature to +85°C and dwell for 30 minutes.
Thermal shock: Perform thermal shock per MIL-STD-810C Method 503.1. Three thermal cycles from +71°C to –57°C
   with a 5 minute maximum transfer time and a 4 hr dwell at each temperature plateau.
Altitude: Normal operating – test per MIL-STD-810F, Procedure 2. Reduce pressure at a rate not to exceed
   2,000 Ft/min to an altitude of 50,000 ft. Dwell for a period of 1 hr.
Explosive decompression: Test per MIL-STD-810F, Procedure 4. Reduce chamber pressure to 2,437m (8,000 ft),
   then in <0.1 seconds reduce pressure to an altitude of 12,192 m (40,000 ft). Maintain this pressure for 10 minutes.
Salt and fog: Test per MIL-STD-810F, Method 509.4. Perform 2 cycles of salt fog of 24 hrs and 24 hrs drying per cycle.
Explosive atmosphere: Test per MIL-STD-810F, Method 511.4, Procedure 1 (operation in explosive atmosphere).
