Frequently Asked Questions About Speed Brakes
6. Your Burning Questions Answered
Let's tackle some common questions about speed brakes to clear up any lingering curiosity.
Q: Are speed brakes the same as flaps?
A: Not quite! Flaps increase both lift and drag, typically used during takeoff and landing to allow for lower speeds. Speed brakes primarily increase drag, allowing the plane to slow down more quickly without significantly affecting lift.
Q: Can speed brakes be used during takeoff?
A: Generally, no. Speed brakes are designed to slow the aircraft down, so they would be counterproductive during takeoff, which requires maximum lift and thrust. Unless the pilot rejected the takeoff for some reason, then they are used to slow down the plane quicker on the ground.
Q: What happens if the speed brakes fail?
A: Aircraft are designed with redundancy in mind. Pilots are trained to handle such situations, and other control surfaces, like flaps and spoilers, can be used to help manage the aircraft's speed and descent. Air traffic control will also assist in finding a safe landing solution.
Q: Do all airplanes have speed brakes?
A: While most commercial jets do have speed brakes, not all airplanes do. Smaller general aviation aircraft may rely on other methods to control speed, such as reducing engine power or using flaps.
