Answer :
Final answer:
Accelerated Stop Distance Available (ASDA) is the length of the runway plus the stopway, an aviation term critical for determining aircraft safety during aborted takeoffs.
Explanation:
The Accelerated Stop Distance Available (ASDA) is defined as the length of the runway plus the stopway. This is a term used in aviation to describe the total distance available for an airplane to come to a complete stop after aborting a takeoff at high speed before the aeroplane reaches a speed where it can no longer stop safely within the confines of the runway. The ASDA is an important factor in determining whether an aircraft can safely operate from a given runway, taking into account possible emergencies that may require a sudden stop during the takeoff phase.
