Create a mission:

1. place a helicopter unit where the player is the pilot
2. put this into the init.sqf of the mission:

waitUntil{!(isNull findDisplay 46)};
(findDisplay 46) displayAddEventHandler ["KeyDown", {
_handled = false;
if(_this select 1 == 59) then {
1 fadeSound 0.5;
_handled = true;
};
_handled;
}];

The action is now on F1.

3. Start, fly a bit, press boost and a direction key at the same time and spam F1.
4. See how your controls should freeze
