The purpose of this Safety Enhancement is to improve flight crew awareness of airplane position on the runway and distance remaining during takeoff roll and landing rollout. Airport operators should add, as feasible, distance remaining signs on runways at Part 139 airports where Part 121 operations are conducted.
CAST's Joint Implementation Measurement and Data Analysis Team (JIMDAT) provided a prioritized list of runways without "distance remaining" signs to the FAA's Airports organization. This completes Output 1 of the Safety Enhancement.
