dresoccer4 Posted January 10, 2020 Share Posted January 10, 2020 so i just landed but had no brake pressure :( however my landing was so good that i was able to roll the entire length of the runway and come to a complete stop with no brakes :D but anyway, i checked the gear handle and it's in the neutral position, but the pressure gauge is still 0. i thought that if the gear handle was neutral then the pressure pump would refill it? can someone please fill me in on whats happening?

Kang Posted January 10, 2020 Share Posted January 10, 2020 There is no pump to refill the air on the MiG-21. It's a tank of compressed air and if you use it up, it's all gone. It has to be replaced/refilled by ground crew. The whole thing about the gear handle is that if you forget to return it to neutral and leave it in up after take-off, the wheel brakes will stay engaged thus depleting the air over time for no benefit to you. If you use a lot of air otherwise (for example using the brakes, or just extending and retracting the gear a lot) you might end up with low pressure left.

IVAN01rch Posted January 22, 2020 Share Posted January 22, 2020 You also should depress flapper position button! Link to comment Share on other sites More sharing options...
AeriaGloria Posted January 22, 2020 Share Posted January 22, 2020 Doesn’t that just increase the lifetime of the springs?

Kang Posted January 23, 2020 Share Posted January 23, 2020 Doesn’t that just increase the lifetime of the springs? I'd think so. It certainly does not use any of the compressed air at least. Link to comment Share on other sites More sharing options...
Skopikus Posted March 9, 2020 Share Posted March 9, 2020 Maybe you pressing brakes in air? It was my case when I forgot to "invert" brake control in settings and my brakes was always on. Link to comment Share on other sites More sharing options...

JIMJAM Posted March 23, 2020 Share Posted March 23, 2020 Just got it and LOVE the plane. Reminds me of the F-104. If you don't show the proper respect and get sloppy it will bite you in the butt. Every button/switch etc on my TM HOTAS is valuable and I have FIVE dedicated just to the gear! Now that I have about 1 hr tt in her I can free some up but in VR looking down towards the gear/AP etc is tough. I have also flown into the ground while trying to find these very small switches.

rossmum Posted March 24, 2020 Share Posted March 24, 2020 I have all the gear controls bound on my HOTAS for muscle memory purposes (same with weapons control panel). It's easier to reach for something IRL than swap hands on the stick, look at the relevant control, move the mouse to it and click it while my subtle head movements are making it hard to be precise, then swap hands again.

JG14_Smil Posted March 26, 2020 Share Posted March 26, 2020 I've seen pneumatic function loss with a full tank of air. Is it tied to running engine below a minimum RPM? I was experimenting with going below 80% when it happened. Link to comment Share on other sites More sharing options...
rossmum Posted March 27, 2020 Share Posted March 27, 2020 It should be totally independent of the engine, it's feeding off a fixed air tank rather than the bleed air off the compressor. I don't know how the tank would be full but the system not functional, I've never experienced it. You're absolutely sure the gauge read full for both normal and emergency pressure?

2IAE-CrashBG Posted March 28, 2020 Share Posted March 28, 2020 How long after take off did you put the handle in neutral? That air is also used to stop the wheels from rotating after you put the gear up [sIGPIC]http://i43.photobucket.com/albums/e381/46crash/crahshig.png[/sIGPIC] Bulgarian DCS Community Link to comment Share on other sites More sharing options...
