Final answer:
The stall speed in the normal landing configuration is 1.3 times the power-off stall speed in a specified configuration.
Step-by-step explanation:
The stall speed in the normal landing configuration is 1.3 times the power-off stall speed in a specified configuration. When an airplane is operating in a normal landing configuration, it is descending with flaps extended, which increases the lift coefficient and decreases the stall speed. The power-off stall speed refers to the minimum speed at which the airplane can maintain controlled flight without engine power.
