Radio Stack
This panel, visible by pressing SHIFT + 2 is entirely fictitious but contains some useful controls. The radio stack is taken from the default FS98 737 and works in conjunction with the major navigational instruments on the main panel.
At the top of this panel is a button that allows the arming of the aircraft spoilers. The idea is that the spoilers will then be automatically extended when the aircraft lands.
To the left of the radio stack is a green (orange when pressed) parking brake button. Below the brake are two switches, one for fuel and the other for ignition. If you like to start your flight with the engines off (as it should be) then you will need to ensure that the parking brake is "on" before starting the engine. I will not be held responsible for damage to the aircraft, property or personnel if you start the engine without first applying the parking brake.
