Answer: A

Which of the following statements about the stall of a straight wing aeroplane is correct?

A: Buffeting is the result of tailplane flow separation..
B: Just before the stall the aeroplane will be have an increased nose down tendency.

What is the advantage of a balanced field length condition ?

A: For a balanced field length the required take-off runway length always equals the available runway length.
B: A balanced take-off provides the lowest elevator input force requirement for rotation.
C: A balanced field length gives the minimum required field length in the event of an engine failure.
D: A balanced field length provides the greatest margin between “net” and “gross” take-off flight paths.
