BBQ Posted July 10, 2013 Share Posted July 10, 2013 I'm testing a mission, and realized when I had landed, that I missed an objective, and need to refuel and head back out. However, before I landed, I noticed my pitch autopilot channel was disengaged. I thought I might have taken some small arms fire or something, and since I was about to end the mission and land, didn't bother to investigate codes presented on EKRAN. Then I realized I missed an objective -- but since I had landed, the EKRAN apparently reset/finished it's fourth cycle, and so now I'm trying to figure out what is wrong with that channel. Hydraulics are all good -- the gauges all read between the lines. I've tried emergency disengage autopilot channels, and then re-enabled them each -- but the Pitch channel refuses to activate. I'm trying to look at this problem as if I'm still in flight, when in fact I'm on the runway, ready to take-off again -- the mission does not allow external views, so I can't do a BDA on the aircraft externally. Any troubleshooting advice? All other systems appear solid. :helpsmilie: Link to comment Share on other sites More sharing options...
justoc Posted July 10, 2013 Share Posted July 10, 2013 (edited) Kill your engines and repair? If not, it shouldnt be entirely too difficult to fly without that channel. Edited July 10, 2013 by justo(c) [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
BBQ Posted July 10, 2013 Author Share Posted July 10, 2013 Kill your engines and repair? If not, it shouldnt be entirely too difficult to fly without that channel. It's a nasty bit of high altitude mountain flying -- but I didn't know that "repair" was an option. Does that automatically happen when you refuel/rearm as long as the engines are off? I refueled with engines on - throttles to idle, but did not turn engines completely off. Link to comment Share on other sites More sharing options...

Engines need to be off for repairs. Believe you can leave the APU running though. To repair use the radio menu, ground crew, and ask for repairs.

justoc Posted July 11, 2013 Share Posted July 11, 2013 Thanks! Back to Sochi ... :thumbup: I learned that rather recently as well, always wondered why the repair would never work. [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
159th_Falcon Posted July 11, 2013 Share Posted July 11, 2013 One more thing, if the airport your landing on is not friendly. (ie neutral or enemy) you cannot rearm/refuel/repair there. You can check the F10 map view and click on an airports icon to see the coalition it belongs to.

seikdel Posted July 12, 2013 Share Posted July 12, 2013 FWIW, the Bank and Pitch channels are both dependent on the INU, so if you a) took INU damage or b) forgot to turn it on (I'm guilty of this), they won't work. Not sure what's happening if only one of them fails, though. 1 Link to comment Share on other sites More sharing options...
BBQ Posted July 12, 2013 Author Share Posted July 12, 2013 You nailed it seikdel -- I had indeed, forgot to switch on the INU at startup! Link to comment Share on other sites More sharing options...
seikdel Posted July 13, 2013 Share Posted July 13, 2013 Awesome. I love finding out that a fix is simple =) 1 Link to comment Share on other sites More sharing options...
BBQ Posted July 13, 2013 Author Share Posted July 13, 2013 Is it possible ony the one channel is dependent on the INU? Link to comment Share on other sites More sharing options...
Davis0079 Posted July 13, 2013 Share Posted July 13, 2013 the alt hold is dependent on the radar and barometric altimeters (possibly even the INU).....the heading hold is dependent on the compasses most likely (possibly even the INU...but the compass sounds like the easier way to tell heading)....the only way the aircraft computers can know your pitch and bank degrees is the INU......its a set of gyros and a computer that calculates the movement of the airframe..... I could be wrong...but I believe the previous poster is correct in saying that BOTH pitch and bank are INU dependent.... It only takes two things to fly, Airspeed and Money.
