Failures!

[lanmancz]

Heh, so apparently there are random failures already present in the model! I wasn't aware of that but I just had a captain's altimeter fail, got stuck at 510 ft. Have to fly from FO side for change Nice!

Hello

Random failures is not simulated by IXEG. So it must have been builtin failures by x-plane that are enabled.

Correct - quite a few of the built-in X-Plane failures will work, because some of our systems are default X-Plane systems. Some systems you can fail through our FAILURES menu.

So I just had another one, FO's airspeed indicator this time. Lol, I was flying this plane since day 1 without a single failure and now I get 2 within 3 flights

Anyway. How do you please select which speed indicator should the auto-throttle use as a reference ? Or does it need both instruments operating in order to work properly ? Because I now have FO's speed indicator stuck at 843 knots and the A/T is a bit confused and tries to retard my throttles if I arm it. I don't think I see any air data selector in the cockpit (like in the 757/767). I'm currently running on CMD A in LVL CHG+LNAV mode with manual throttle setting. It keeps the selected IAS by applying correct pitch but the moment I arm the A/T it retard the throttles to idle.

edit: lol the FO's digital instrument readout can surely show some funky values while malfunctioning - I think 94563 knots was the record I've seen so far :-) The analog one is just stuck on max.

edit2: Oh I've just noticed that the entire pitot-static system on FO's side is screwed. Altimeter and vertical speed is dead as well. I didn't notice it at low altitude.

edit3: Ah, there is the EFI selector switch on the overhead panel which I can select to 1 which now feeds both displays correct data from the first system but arming A/T still shows crazy numbers in the IAS/MACH window (like 20000) and tries to retard the throttles. Shouldn't the A/T be also fed from the selected system ?

Hi, we don´t really code or allow for the X-Planes failures to work properly - so all bets are off. We recommend flying without X-Plane´s failures enabled, doing so may give you weird results.

That being said, its perfectly normal for the autothrottle to go to idle during LVL CHG (in a descent). But if you have a huge airspeed, the reversion mode will kick in and try to retard the throttles as well...

Ah, ok. I will disable them then. Good to know that it's not really supported.

I was actually climbing at the time. The 2nd pitot-static system completely failed shortly after takeoff. As I later in the flight figured out I could switch the EFI to get data solely from the system 1 and managed to land at my destination safely The A/T was completely unusable during the flight though because even with EFI set to 1 it was still thinking I was overspeeding.

Anyway, thanks for reply!

Btw : Should I also disable the default xplane damage settings ? (gear door, flaps, surfaces)

[Litjan]

Yeah, I would think so - disable all of X-Plane´s failures (remove flaps in overspeed, etc...).

Some failures will work (like engine fire, failure, etc.) - others might cause unwanted effects. I think you still did good to work around the problem and safely land, though! Thats why we have humans in the cockpit - they can think outsided the box and do stuff that a computer can´t plan for...
