What is the maximum airspeed limit of the Landing Light while it's extended?

• A. 180 knots
• B. 130 knots
• C. 170 knots
• D. 200 knots

Answer: (A)

Extending the landing light adds drag and subjects the light assembly, wiring, and mounting to higher aerodynamic loads. To protect that hardware and keep the light reliable, the flight manual sets a maximum airspeed for the extended configuration. The published limit is 180 knots, so staying at or below this speed keeps the light and its mechanism within safe structural tolerances, even with gusts or maneuvering. Speeds above 180 knots could over-stress the extended light or affect its alignment, risking damage or failure. So 180 knots is the correct maximum. Lower speeds listed are acceptable but not the maximum, and 200 knots would exceed the limit.
