How long do pilot-controlled runway lights remain on after activation?

Pilot-controlled runway lights are designed to enhance visibility at airports during takeoff and landing, particularly in low visibility conditions. When activated by a pilot using the designated radio frequency, these lights will remain illuminated for a specific period to provide adequate time for the pilot to taxi or take off without the need for constant reactivation.

Option B, which states that the lights remain on for 15 minutes after activation, is correct. This duration is generally established to balance between sufficient time for the aircraft's operation and the need to conserve energy and reduce unnecessary light pollution for surrounding areas. The 15-minute duration also allows for flexibility, as pilots may need a little time to securely prepare for their flight operations.

Understanding the correct activation duration of pilot-controlled lights is essential for pilots as it ensures they can plan their movements efficiently while in the vicinity of the runway. This knowledge is crucial during both training and actual flight operations.
