- Sinônimos
- air brake
- Definição1
- A type of secondary control on an airplane, a control which does not rotate the aircraft about any of its three axes. Speed brakes produce drag without affecting lift, or causing the aircraft to pitch. The drag they produce allows a highly streamlined airplane to descend at a steep angle without picking up excessive speed.

- Contexto
- Although performance data in the pilot’s or operations manual may provide some useful information, the actual conditions of the accident will rarely be the same as assumed for the manual’s performance charts. A few knots’ difference in assumed rejected takeoff or touchdown speed, or a few seconds’ delay in speed brake deployment, can have a significant effect on stopping distance. Once again, the Performance Group should solicit the assistance of the aircraft manufacturer for more accurate analyses.
- A flight manual discussion included a comment that the circuit breaker should be reset during taxi “after landing.” This step was included in the “Approach and Landing” phase of the checklist without any clarifying statement. The crew reset the circuit breaker at the time sequence for before-landing procedures which resulted in the air brake deployment and subsequent hard landing.
