Exterior section
In the "Exterior" section of the manual, you can select the aircraft's external options.
Wheel chocks
To immobilize the aircraft on the ground, use wheel chocks.
They work as parking brakes. You can use the usual game shortcuts for them (on the keyboard, HOTAS, or button boxes).
You can also activate and deactivate them from the cockpit by clicking on the wheels.
The activation option is available in the book in the EXTERIOR section.
