Chuck's Mirage F1 Guide

[Iron Sights]

I thought you just didn’t deploy airbrakes while landing, but I thought was ok after touchdown. It looks like the airbrakes might strike the ground on landing, if deployed, but I am not sure this. Seems like it should be ok to open them after you touch down. However, I also always use the chute, since she always seems squirrelly until the chute kicks in.

On what I have it says : 
No Airbrake during flaring and keep RPM above 7000.

And the manual doesn't say to use Parachute in every case but mainly with a plane above 11T.
They tell how to airbrake to 100knots as follow : 

Keeping the nose high at 13° of AOA and then at about 100knots putting the nose down and brake.
