At what speed does the stall warning indicator activate?

The stall warning indicator activates at a speed range that is designed to provide pilots with a timely warning before reaching the critical stall speed of the aircraft. In the case of the King Air 350, the correct answer is that the stall warning indicator activates 5 to 10 knots above stall speed. This range is crucial for ensuring that pilots have a buffer zone to react appropriately and take corrective actions to prevent a stall situation.

The indicator's activation at this speed is important because it allows pilots to react before the aircraft reaches an aerodynamic condition where control could be lost. This proactive system enhances flight safety by encouraging vigilance and promoting better handling technique in various phases of flight, particularly during approaches and go-arounds where stall risks are heightened.

Understanding this speed range is vital for pilots flying the King Air 350, as it helps them maintain situational awareness and make more informed decisions regarding their flight operations.
