Mirage F1CE/EE Speed brake function.

At present the Speed brakes can only be selected IN or OUT. This is incorrect.

MOMENTARY BLIP FUNCTION

IRL you can momentarily hold or "Blip" the speed brake. This involves "Blipping" of the speed brake or holding the speed brake to an intermediate position. If "blipping" the speed brake switch the Speed brakes will only deploy for as long as the switch is held in the intermediate position. As soon as the speed brake is released then the speed brakes surfaces retract. This is ideal for formation work when all you need is a little drag increase for a short period RFN. See video below Pilot is "blipping" the speed brake.

So if the pilot wishes he can move and hold the speed brake to the intermediate position the speed brakes will fully extended. as soon as the speed brake switch is released then they will retract.

LOCK FUNCTION

This is the only function currently modeled in DCS F1. this is used for long duration speed brake events, like descents etc. iRL the pilot must press the speed brake switch aft through an internal detent. The switch then remains in the locked OUT position. the pilot can remove his thumb from the speed brake switch.

The video below is of a Mirage IIIO Speed brake switch in operation the F1 is identical. You can clearly see the operation of the detent switch.

The airbrake is able to be momentary for me. There are three bindings required.

"Airbrake" is momentary
"Airbrake On" locks the switch into position
"Airbrake Off" does what you expect it to
