What happens to the speed brake when the flaps are extended?

When the flaps are extended, the speed brake will remain extended. This is because the design of the aircraft systems often allows the speed brakes to operate independently of the flap position. The purpose of the speed brake is to increase drag and reduce lift, allowing for more controlled descent and approach speeds, which is particularly useful when the aircraft is configured for landing with extended flaps.

In many aircraft, the speed brake system is designed to provide enhanced control during approach and landing, ensuring that the pilot can manage the descent profile effectively. The independent operation of the speed brakes, in relation to the flaps, allows pilots to use both systems for their specific performance benefits without one interfering with the other. Therefore, the correct response highlights the functionality of the speed brake mechanism in conjunction with flap deployment during flight operations.
