For normal configurations, is approach speed the speed used on final approach with landing flaps and slats?

The statement is true because, during the final approach phase of flight for normal configurations, the approach speed is indeed the designated speed at which the aircraft operates when landing flaps and slats are deployed. This speed is calculated based on a variety of factors including the aircraft's weight, configuration, and environmental conditions.

Approach speed is essential to ensure that the aircraft remains within safe operating margins at all times during this critical phase of flight. It allows for adequate control and responsiveness, ensuring that the pilot can manage the aircraft effectively while aligning with the runway for landing. The use of landing flaps and slats serves to enhance lift and improve aircraft handling characteristics at slower speeds, making adherence to the approach speed vital for a safe landing.
