What title says. Afaik the air would push them down again when pushing the retract button.

not a bug. There are no flaps in M2K. You talking about dive brakes and they will not work when out of fuel and engine stopped.

 

From the manual

Additionally, there is a reserve electrical pump (EP) which is connected to system 2 and that automatically starts when the pressure in system 2 fells below 160 bars. This pump provides 190 bars of pressure only, for flight controls and parking brake/emergency brakes accumulator.

 

 

Now if you run out of fuel, you only have a short time of battery life so it will not work for long.

 

Out of fuel mean M2K is now a lawn dart with no input/control once battery dies (which is rather quick if you have all systems on). Remember this is a FBW plane.

1- learn the correct name of the system you want to describe. As said there are no flaps, but airbrakes and SLATs (becs).

2- RTFM, p55. These systems are on HYD 1, not backed up by EP.

Sorry meant airbrakes, was super tired when reporting this. Airbrakes wont retract (go back inside) when deployed and pressing button again. is this realistic? Do I have to switch off battery for a few seconds to make airbrakes retract (/as then hydraulic pump would go off/pressure would drop then I hope?)

Sorry for confusion with flaps.

What was the situation ?

We’re you in flight with engine off or on the ground ?

 

Hyd 1 & Hyd 2 are driven by the rotating engine.

EP driven fed by the battery only back up some emergency systems on Hyd 2 (emergency landing gear, emergency break).

 

Air brakes are on Hyd 1.

 

If no pressure in Hyd 1 we can assume it should loose pressure and maybe retract. That is a point to dig.

Maybe its just your control mappings? Are you sure you have mapped the toggle airbrakes command to your selected button and not the extend command?

2500% positive I pressed correct button.

 

Was in flight, fuel empty ("gliding"), so by battery powered hydraulic system. deploy worked fine, could not retract anymore. was doing at least Mach 0.5

But are you sure that the button you pressed isn't mapped to just extend airbrakes?

 

Edit: Ah, if you are out of fuel and your systems offline, then the airbrakes will not retract. i have had this a number of times, when my AA refuelling skills have, shall we say, not been up to the mark. Whether this is realistic or not, i couldn't say, but i suspect that it probably is.

yes 2500%, I use that button in EVERY hard turnfight I do (so nearly daily basis).

What we would need to know is your engine's RPM, since HYD 1 is driven by engine.

Whether airbrakes retract ("fermer") or not is depending on engine RPM?? wow.

No, but it would be useful to find the threshold where there isn't enough RPM to drive HYD 1 pump.

Oh. This is a very good thing to test (for one of Razbams testers).
