What is the minimum safe single-engine speed (Vsse) in KIAS?

The minimum safe single-engine speed (Vsse) is a critical parameter for multi-engine aircraft operation, especially during engine failure scenarios. Vsse represents the minimum speed at which a pilot can safely attempt to maintain controlled flight with one engine inoperative. Typically, this speed is determined by the aircraft manufacturer and is often found in the Pilot Operating Handbook (POH) for specific aircraft.

For the option identified as correct, 82 knots indicated airspeed (KIAS) serves as a speed that ensures adequate control and performance can be maintained even with one engine not functioning. It is set above the stall speed in the clean configuration for a multi-engine plane, which allows for maintaining control authority during critical phases such as engine-out procedures.

The other options do not meet the requisite speed to ensure safe operation in a single-engine environment, as they might either be too low, which could lead the pilot into the stall region if an engine fails, or not aligned with typical values prescribed for comparable multi-engine aircraft. Therefore, 82 KIAS is recognized as the standard for minimum safe single-engine operation, encapsulating both performance and safety considerations imperative for effective flight in a multi-engine environment.
