retractable landing gear
- Sinônimos
- retractable undercarriage
- Definição1
- The type of landing gear that can be folded up into the structure when the aircraft is off the ground. A fixed (nonretractable) landing gear produces a large amount of drag when the aircraft is flying at a high speed. To reduce this drag, the landing gear is retracted, or folded up into the structure.

- Contexto
- Retractable landing gear can present additional problems. Landing gear operation usually induces pitching moments and drag which should be considered by the investigator. If the landing gear is retracted or extended at airspeeds greater than the placard speed, structural damage may occur, especially regarding gear doors and fillets.
