Q7
To minimize the risk of hydroplaning during the landing the pilot of a modern airliner should:
- A make a "positive" landing and apply maximum reverse thrust and brakes as quickly as possible
- B use maximum reverse thrust, and should start braking below the hydroplaning speed
- C use normal landing, braking and reverse thrust techniques
- D postpone the landing until the risk of hydroplaning no longer exists
Show answer
Correct answer: A. make a "positive" landing and apply maximum reverse thrust and brakes as quickly as possible

- A Positive touch down, full reverse and brakes as soon as possible.
- B Smoothest possible touch down, full reverse and only brakes below VP.
- C Positive touch down, full reverse and only brakes below VP.
- D Normal landing, full reverse and brakes at VP.
Show answer
Correct answer: C. Positive touch down, full reverse and only brakes below VP.

- A LDR decreases and go-around performance is improved.
- B LDR increases and go- around performance is degraded.
- C LDR is decreased and go-around performance is degraded.
- D LDR is increased and go-around performance is improved.
Show answer
Correct answer: C. LDR is decreased and go-around performance is degraded.
