Loss of Tail Rotor Efficiency

What does LTE stand for in the context of helicopters?

• Loss of Total Engine

• Loss of Tail Rotor Efficiency

• Limited Thrust Engagement

• Lateral Torque Effect

What is the primary cause of Loss of Tail Rotor Efficiency (LTE)?

• Technical failure of the engine

• Maintenance error

• Wind conditions

• Pilot fatigue

Under what general flight conditions is Loss of Tail Rotor Efficiency (LTE) most likely to occur?

• High forward speed and low power

• High altitude and low temperature

• Very little or no forward speed and high power

• During autorotation

For which type of helicopter is the explanation of LTE in this video primarily applicable?

• Helicopters with the main rotor turning clockwise

• Helicopters with the main rotor turning anti-clockwise

• Helicopters with two main rotors

• Helicopters with no tail rotor

In the first case of Loss of Tail Rotor Efficiency (LTE), what interferes with the tail rotor?

• Engine vibrations

• Main rotor disk vortices

• Turbulence from the main landing gear

• External objects hitting the tail rotor

What wind conditions, relative to the helicopter's 12 o'clock position, are associated with the first case of LTE?

• Wind of 5 to 17 knots from the 12 o'clock position

• Wind of 5 to 17 knots from the 10 o'clock position

• Wind of 5 to 17 knots from the 3 o'clock position

• Wind of 10 to 30 knots from the 6 o'clock position

What wind conditions, relative to the helicopter's 12 o'clock position, are associated with the second case of LTE?

• A crosswind of 5 to 17 knots from the 7 to 11 o'clock position.

• A headwind of 20 knots or more.

• A tailwind of 5 to 10 knots.

• No wind conditions specified.

What wind condition is described as the third case of LTE?

• A strong headwind.

• A wind of 10 to 30 knots coming from behind the helicopter.

• A wind from the right side of the helicopter.

• No wind, only engine failure.

What is the primary danger associated with Loss of Tail-rotor Effectiveness (LTE)?

• Rapid forward acceleration of the helicopter.

• Sudden loss of engine power.

• Rapid, uncontrolled yawing of the helicopter.

• Unexpected increase in altitude.

Which flight condition increases a helicopter's risk of experiencing Loss of Tail-rotor Effectiveness (LTE)?

• Flying at low altitude with high speed.

• Flying in cold weather with a light load.

• Flying at high altitude, in hot conditions, with a heavy gross weight, and at slow speed.

• Flying with strong headwinds.
