NVG briefing guide

1. Solar/Lunar Considerations 2. NVG preflight will be completed by all crewmembers in the paraloft prior to flight utilizing the Hoffman box.
 * a. Sunrise/sunset-EENT sunset will be at _____ EENT will be at _____
 * b. Moonrise/moonset- Lux/luminance levels moonrise will be ____, moonset at ____ the peak luminance will be ____%
 * c. Moon angle/azimuth breif the SLAPS data and how it will affect that night's flight. For example, the moon will be low in the east and winds and the course in use will be 090 at Santa Rosa, the visibility will be degraded due to moon degaining the NVGs.
 * d. Shadowing shadows during the flight will be on the ___ side of objects and will be ___ in length. During the night they will be shifting to the ___ and getting longer/shorter.
 * e. Ambient light brief working area cultural lighting
 * f. Visual Illusions It will be difficult to discern colors of lights due to NVG limitations. Brighter lights are not necessarily closer lights. Aircraft and tower lights that are close to the horizon may blend in with lights on the ground making them difficult to see.

3. Goggle/degoggle procedures we will be utilizing chock to chock tonight. If there is any reason that a crew member needs to degoggle he will keep the flying pilot informed to the status of the NVGs.

4.Internal/External aircraft lighting 5. Radar altimeter will be set to ___ during the navigation route and while in transit.
 * a. Anti-collision lights will be utilized in accordance with the SOP. Lights will be turned on crossing the hold short line and off upon returning. They may be secured in the low work area at Santa Rosa. If they become a hazard to flight they may be secured.
 * b. Navigation lights will be utilized per the SOP and remain steady bright during the flight.
 * c. Use of searchlight will be use in accordance with SOP and Read and Initial. it will be slewed to a position to minimize impact on crew's visibility.
 * d. Internal aircraft lighting will be set at a comfortable level for the aircrew.
 * e. Map light/ lip light will be used in the NVG compatible mode as required.

6. 'Hazards brief hazards in the operating area and along planned route.

7. LZ operations brief OLF or airfield to be used.

8. NVG emergencies
 * a. Aircraft/System If the aircraft experiences an emergency or system failure the aircrew will remain goggled unless troubleshooting is inhibited by their use. If the nonflying pilot degoggles, they shall inform the flying pilot and regoggle no lower than 200 feet prior to landing.
 * b. NVG failure If either crewmember experiences an NVG failure, they will: switch to an instrument scan, inform the other crewmember that they have "goggle failure, you have the controls." A positive three way change will be completed. If the failure occurs at or below 200' in the pattern a waveoff shall be initiated by the flying pilot. If the failure occurs on takeoff the flying pilot will continue takeoff using ITO procedure and complete control change as above. Once the aircraft is in a safe regime the crew will determine if the NVGs can be swapped with the spare set. Then the aircraft commander will make a decision on the continuation of the conduct of the flight.
