What does RESA stand for?

RESA stands for Runway End Safety Area. This term refers to a designated area at the end of a runway that is designed to enhance safety by providing a buffer zone in the event of an overrun or undershoot of aircraft during takeoff or landing. The primary purpose of a RESA is to reduce the risk of accidents and damage to the aircraft and its occupants when an incident occurs at the runway's end. RESAs are critical components of airport design and operate under specific regulations to ensure that the area is properly maintained and kept free of obstacles.

The other options do not accurately represent the standard terminology used in aviation safety. For example, "Runway Emergency Safety Area" and "Reinforced Emergency Safety Area" do not exist as recognized terms in aviation. Similarly, "Runway End Safety Act" appears to be a misnomer, as there is no legislative act specifically by that name that pertains to this safety standard. Understanding the terminology and its implications is essential for anyone involved in airside operations and safety.
