What was the benefit of a retractable landing gear?
The primary benefits of being able to retract the landing gear are increased climb performance and higher cruise airspeeds due to the resulting decrease in drag. Retractable landing gear systems may be operated either hydraulically or electrically or may employ a combination of the two systems.
How many types of retractable landing gear systems are there?
There are three main types of Retractable Landing Gear, Electrical, Hydraulic, and Manual. Each have their pros and cons, but each operate on the same principles and generally only differ in their actuation system. Manual systems are the simplest, but are only used on small, low performance aircraft.
What type of motor is used in retractable landing gear system?
reversible electric motor
This system uses a two-position switch on the instrument panel, not unlike other landing-gear switches. In the Piper system, the switch controls a reversible electric motor. This motor is powered by the aircraft’s electrical system to operate a hydraulic pump used to pressurize hydraulic actuators.
Which motor is used in retractable landing gear system?
What are the 4 different landing gear types and discuss their features?
There are 4 basic categories of Landing Gear that General Aviation planes use: Tricycle, Tail-Wheel (Conventional), Pontoons, and Skis. Tricycle Gear planes are by far the most common, as they are only marginally heavier than the older Tail-Wheel design but have several advantages.

What is a retractable landing gear?
Retractable landing gear is designed to streamline the airplane (reduce the drag) by allowing the landing gear to be stowed inside the structure during cruising flight. Fixed landing gear is common with slow (e.g. general aviation) aircraft and most commercial aircraft use retractable landing gear.
What are the three basic landing gear types?
The Essential Types of Landing Gear
- Conventional Landing Gear. Conventional, tail dragger or tailwheel-type airplane landing gear — it goes by many names.
- Tandem Landing Gear.
- Tricycle-Type Landing Gear.
