What is the power-off stalling speed associated with?

1. Landing configuration only

2. Takeoff configuration only

3. Both landing and takeoff configurations

4. Climb configuration only

The correct answer is: Landing configuration only

The power-off stalling speed is primarily associated with the landing configuration of an aircraft. When an aircraft is in a landing configuration, it typically has a slower speed due to the extended flaps, which increase lift at lower speeds but also create more drag. This means the aircraft will reach its stalling speed (the minimum airspeed at which steady level flight is possible) at a higher angle of attack compared to clean or takeoff configurations. In landing configuration, pilots need to be aware of the power-off stalling speed as this is critical during the final approach and landing phases. If an aircraft is stalled during landing, particularly at low altitudes, recovery can become challenging and dangerous. While takeoff configuration may also be a consideration, the specific context of power-off stalls emphasizes the scenario where sufficient power is not available, making it most relevant to landing situations where maintaining control and speed is vital as the aircraft approaches the runway.
