Why do you think pressing APU bleed should do anything other then stop bleed air from the APU?

The md-11 has feature when after egine start and all systems have been switched over to the engines by the apu, you switch the apu air bleed off which starts an automatic apu shut down. On the apu section on the OH panel the off light is on and the apu should shut down.chris finlay

Chris,Like it you are aware of this system feature.You'r absolute right here, however the APU shutdown cycle takes about 90 seconds.Just checked it in my FSX version and it worked correctly, no bug involved there.Wonder why it's not working for you.Regards,Harry

Chris,Just reading this posting as well, but during a turn-around situation.Should work as if it was a 'first' start.Probably a bug indeed.Regards,Harry

First thanks to PMDG-Team for this MD11. I like it very much and it

Paul,if you believe me or not, this white dotted arc wasn't any new information for me. I wouldn't post here, if this bug is based on my handling. You didn't find any mistake in my depiction. My intension is not to blame developers, i want to prevent this 100%, and this isn't possible, when i fly under ATC conditions. I said this turns happens randomly.I did this flight yesterday once more and found another bug in MCDU accidentally. I was on my intercept turn, short before capturing ILS RWY 29 in Vienna. ATC gave me spontanly no clearance to capture ILS29 (he likes to stress me:-)) and instructed me a first heading of 285 and a new ILS11 to Capture due to ground conditions, i was in heading select mode, this gave me time to input new the RWY Info and i cleared then the discontinuity to the FAF as i do it most. At this time NAV Mode became active again without pushing the NAV button and aircraft turned direct to the IAF, but it should hold the preselected heading of 285, til i push NAV again. i fixed it manually, but the more you fly the aircraft under real conditions the more bugs you will detect.To fly complete automated star and transition, aren't real conditions, not even to test selected heading when coming out of NAV mode.
Hi, I think my pictures will explain why and what happens. But when Autoland is activated, it will override the NAV and HDG selections. No bug. Maybe in 747 I had to deactivate the FlighDirector

Hi Paul,yes, it must be a bug. I had a similar situation approaching EDDF, I had to leave a waypoint at a heading with left turn and then the airplane makes a nearly 360

While Rollout I use the feet to brake the airplane when the speed is 30 Knots or minor. But when I set Auto Brakes to off before using the manual brakes, the airplane will stop and I found no way to leave the RWY. Online with ATC it would be a very bad situation. You see, no brakes, thrust, but no taxi speed.brakesd.jpg---------------------------------------------------------------------------------------------------------------------------------------
i forget to reply on your "bug"if you are in this situation, press the "AFS override off" buttons, then you will move on. But don't do this during flight, you will lose all protections like stall, etc...To aware from this, choose manual breaking erlier e.g at 80knots. The reason is, some still armed automatism will prevent you from leaving the runway middleline if you choose manual breaking to late. Markus surely is able to give you a more professional comment on this.:-)regardspaul

I did it before, but it makes no difference. I also tried to set Auto Brakes back to Med, than use brakes, nothing changed. And it was no autoland, after approach only was show, the Autopilot was disengaged at 1500 ft.Now I do not set Auto Brakes to OFF before I am on the taxiway to the gate.Regards Peter

autobrakes are disarmed at the moment you decide to break manually. The position the knob has, is as far as i know regardless.are you sure you pushed this buttons, when stucking at the runway?but once more, you should be able to prevent this, when deciding to break manual earliergood luckpaulPS: try to arm AFS after disarming again and give manual thrust, i can't remember when i had this problem at last.

@Paul, maybe the Heading Problem could be prevented when not only turning the Headingbutton. Everytime I use it, first I push it. I hope this will work. :(

Why are you guys not pressing the Hdg/Trk button to zero it to current heading before you change it ? And why aren't you checking the arc before you select HDG mode? If you don't like the arc how long can it take to push the button, start turning it, pull the button to have the aircraft start the turn and then finish turning the knob to desired heading? For you guys understandably embaressed about doing a 360 in the middle of nowhere, what were you doing and for how long before you noticed you were turning in the wrong direction?

Paul Smith.
