300 m
600 m
750 m
Answer is Wrong!
Answer is Right!
The correct answer is B. 300 m.
A clear zone is an area of land that is free of obstructions and is used to protect aircraft during takeoff and landing. The length of the clear zone required for a non-instrument runway depends on the type of aircraft using the runway. For a small aircraft, the required clear zone length is 300 m.
Option A is incorrect because the required clear zone length for a small aircraft is 300 m, not 150 m.
Option C is incorrect because the required clear zone length for a small aircraft is 300 m, not 600 m.
Option D is incorrect because the required clear zone length for a small aircraft is 300 m, not 750 m.
