ATR systems - Landing gear

Correction to the video:
- In the video, I state that the brake overheat alert is triggered when the temperature exeeds 150 °C. This is true for ATR 72. For ATR 42, the limitation is 160 °C. The reason is that they have different brakes.

The landing gear is one of the main systems of an aircraft. The main scope is to support the aircraft during ground operations, take-off, and landing. The landing phase is the most demanding and defines the main design specifications.

The certification requirement is that the main landing gear must be able to absorb a touch down with a vertical speed of 600 feet per minute, or 10 feet per second, at maximum certified landing weight.

This video is meant to give an introduction to the system. For a full description, please read FCOM.DSC.32.
