Aeronautical General Knowledge

To avoid vortex ring state, rotorcraft pilots should:

• Not use roll or pitch

• Increase induced flow

• Not use high-rate vertical descents

• Not use low-rate vertical descents

What are the 3 conditions needed for a rotorcraft to enter vortex ring state in nil wind?

• High rate of descent, powered flight, fast lateral movement

• High rate of descent, powered flight, slow to no lateral movement

• Slow rate of descent, powered flight, slow to no lateral movement

• Slow rate of descent, unpowered flight, fast lateral movement

To recover from vortex ring state, the pilot should NOT immediately apply large amounts of:

• Weight

• Lift

• Drag

• Thrust

If hovering a rotorcraft near an obstacle, such as a building or solid fence, there will be an increase in recirculation. This will cause the RPA to be:

• Cause the rotorcraft to hover

• Pushed up and away from the obstacle

• Pushed away from the obstacle

• Drawn towards the obstacle

When operating a rotorcraft, an increase in induced flow will:

• Increase the angle of attack, but reduce thrust

• Reduce the angle of attack, but increase thrust

• Reduce both the angle of attack and thrust

• Increase both the angle of attack and thrust

During the steady hover of a rotorcraft (no climb or descent), total rotor thrust (TRT) must be:

• Greater than forward speed

• Greater than weight

• Equal to weight

• Less than weight

What is the traditional unit for speed in aviation?

• Knots

• Kilometres per hour

• Feet per second

• Metres per second

Thunderstorms will develop at Port Hedland from 0400 UTC. Port Hedland is eight hours ahead of UTC. What is the local time thunderstorms will develop?

• 1800

• 0400

• 1200

• 1400

When landing a fixed-wing aircraft, a headwind will:

• Have no effect on landing distance required

• Increase the landing distance required

• Reduce the landing distance required

• Not specified

When air traffic control advises that another aircraft is in your "nine o'clock position," where is the aircraft located relative to you?

• Ninety degrees to your left

• Straight ahead of you

• Ninety degrees to your right

• Directly behind you
