Answer is Right!
Answer is Wrong!
The correct answer is B. 5.0 m.
The centre to centre spacing of heliport lighting along the periphery of landing and takeoff area should be 5.0 m. This is to ensure that the lights are evenly spaced and provide adequate illumination for safe landing and takeoff.
Option A is incorrect because it is too small. The lights would not be spaced far enough apart to provide adequate illumination.
Option C is incorrect because it is too large. The lights would be spaced too far apart, which would create a gap in the lighting that could be hazardous to aircraft.
Option D is incorrect because it is not a valid option.
