Brakes

Toe Brakes

The toe brakes are hydraulic disc brakes, fed from the aircraft's single hydraulic system through a dedicated brake accumulator.

Note

Pedal force does not generate the pressure. Without pressure there is no braking, however hard you push.

The brake accumulator is fed from the main system, but isolated from it. In case of a failure of the hydraulic system, use the handpump to get the pressure to 1500 PSI before landing. That should be good for two to three applications of the brakes.

Parking brake

The parking brake works in two modes:

  • Simplified: just toggle the parking brake by whatever means.

  • Realistic: to set the parking brake, pull the handle while toe brakes are fully depressed, then release toe brakes; to release, depress toe brakes fully to unlatch the mechanism. (For convenience, pushing the handle works as well, but that's not realistic, man!)

Chocks

Chocks are deployed by default when you spawn cold & dark, and can be removed using the EFB app. They are removed automatically when you release the parking brake.

The wheel chocks were donated to the project by Bagolu. Thanks!

Known Issues

  • Limitation: In the real Twotter, the parking brake is a latch that holds the toe brake cylinders in place. The mod relies under the hood on the stock parking brake system to hold the aircraft in place, this makes FSEconomy happy. This might be subject to change now that I've figured out how to prime the hydraulics system during load.

  • In Crosswind, the toe brakes can barely hold the aircraft during the 85% Ng run-up.
