NVG Flashcards
What are the considerations for hovering NVG/NVS?
Movement over areas of limited contrast such as tall grass, water or desert, tends to cause spatial disorientation. To avoid spatial disorientation seek areas that provide adequate contrast and use proper scanning techniques.
What are the standards for VMC takeoff?
- Maintain heading +/- 10 deg below 50ft, until clear of obstacles or through ETL.
- Maintain ground alignment with takeoff direction.
- Above 50ft acft in trim.
- Accelerate to desired airspeed +/- 10kts, 5 deg nose low not to exceed 10 deg nose low
- Apply takeoff power - 10% above hover power not to exceed Max Tq until desired alt, vsse or conditions permit.
What are the VMC takeoff considerations under NVG/NVS?
If sufficient illumination exists a VMC takeoff can be performed the same as day. If insufficient illumination does not exist perform an altitude-over-airspeed takeoff, power permitting. Visual obstacle such as shadows should be treated as physical obstacles.
What are the standards for fuel management?
- Determine fuel requirements.
- Verify fuel page settings.
- Verify required fuel for mission at takeoff.
- Compute fuel check 15-30 after entering mission profile.
- Manage fuel system.
- Establish bingo fuel setting.
Bingo-fuel req to fly to refuel sight with vfr/ifr reserve
Joker-fuel level above bingo designated to return to base
What are the standards for VMC Approach?
- Suitable landing area.
- Power req vs power available for approach.
- Maintain constant approach angle.
- Maintain ground track alignment.
- Maintain rate of closure for conditions.
- Align acft with landing direction below 50ft
- Perform smooth controlled termination to a hover or to the ground.
What are the considerations for a VMC Approach NVG/NVS?
Apparent rate of closure may be difficult to estimate at night. During final 100” the rate of closure should be slower than a during the day to avoid sudden attitude changes. Terrain and vegetation may decrease in contrast. Use proper scanning techniques.
What are the standards for hovering?
- Takeoff to a hover - 5 feet
- Perform hover power checks - Go/No-Go Tq
- Determine if power is available for mission - OGE/IGE maneuvers
- Execute descent with minimum drift
Drift IGE +/- 3ft OGE +/-12ft
Heading +/- 10 deg
Altitude IGE +/- 2ft OGE +/- 10ft
What are the VMC confined area considerations?
Size of landing area Suitability of landing area Barriers Approach path Touchdown direction Touchdown point Winds
What are the standards for slope operations?
- Set parking brake
- Maintain heading +/- 5deg
- Maintain min drift after contacting the ground
- Do not exceed slope limits- 7 deg nose up, 12 deg nose down and 10 deg in roll from hover attitude
- Smooth and controlled descent and touchdown
- Smooth and controlled ascent
After achieving desired attitude reduce collective and neutralize collective prior to 25% Tq
What are the standards for roll on landing?
- Touchdown at or above ETL.
- Maintain ground track with min drift.
- Maintain constant approach angle.
- Below 50ft maintain runway alignment +/- 5 deg.
Aerodynamic braking duel engine should be accomplished above 30% Tq.
Rate of closure should be slower than day.
What are the standards for single engine landing?
- Maintain airspeed at or above vsse until 10-20” above intended landing area.
- Maintain ground track with min drift.
- Maintain constant approach angle to first 1/3 of usable landing surface.
- Maintain runway/usable landing area alignment +/- 5 deg.
Aerodynamic braking duel eng 30% Tq or single eng 60% Tq
Rate of closure may be difficult to detect under NVD
What are the standards for a rolling takeoff?
- Stabilator 0 deg
- Simulated power 10% below hover power +/- 3 deg.
- Maintain heading +/- 5 deg.
- Do not allow acft to drop nose low before acft leaves the ground.
- Maintain ground track.
- In trim commensurate with obstacles.
- Establish and maintain climb angle for terrain and obstacles.
- Accelerate to max R/C or desired airspeed.
What are the 3 terrain flight takeoff?
Continuous angle-10% above OGE- robust power
Alt over airspeed- 10% above OGE- marginal pwr
Airspeed over alt- OGE pwr not available
Terrain flight approach.
- Tactical situation
- Long axis
- Obstacles
- Wind
- Arrival path
What are the 3 terrain flight techniques?
- Low level- 80-200’
- Contour- 25-80’
- Noe- Surface to 25’
Pilot should use a shallower than usual approach angle to see over the nose.
