What does RSA stand for in airport operations?

The term RSA in airport operations stands for Runway Safety Area. This area is critical for the safety of aircraft operations, as it is designed to provide a buffer zone around the runway to enhance safety during takeoffs and landings. The Runway Safety Area is intended to reduce the risk of damage to aircraft in the event of an overshoot, undershoot, or loss of control during these critical phases of flight.

In a well-defined Runway Safety Area, specific standards must be met concerning the dimensions and conditions of the area to ensure that it serves its purpose effectively. This includes having the area free from obstructions and properly graded to prevent any hazards to aircraft operations. This emphasis on the physical characteristics and management of the area illustrates its importance in maintaining overall airport safety.
