[BUG] Pulling right engine fire handle causes complete loss of control over the aircraft

Hello,

I seem to be experiencing a recurring issue with engines failing/catching fire (my two first IVAO flights with this Aircraft in a row now after a few flights locally with absolutely no problems) - for now I will attribute this to my inability to properly operate the aircraft.

That being said this is also the second time I have experienced the same somewhat annoying bug, specifically, the repro is :

  1. Right engine fire
  2. Pull the right engine fire handle
  3. Causes the Gizmo log to print out the following error : error: 2218.238: RunLuaFunction(xp): main: [string "JGX.1.Saab.00.lua.aes"]:8357: dref.setInt: Expected two arguments.
  4. Following this, power levers & conditioner levers remain stuck in place & become unresponsive to either the Joystick input, Keyboard and/or mouse
  5. The remaining engine cannot be turned off & will keep delivering the same amount of power that was showing on the dials at the time of pulling the lever.

I was thankfully able to turn back to the airport (this was shortly after take off at 2500ft AGL in the initial climb), land & slam the brakes to kill off the 185kt of thrust still produced by the left engine which I was not able to power down and/or turn off.

I will make sure to check next time - I was very careful with the engines : 

My settings were as follows :

  1. CTOT set to 100% (so reduced from the prescribed 108%) & disabled before initiating the climb
  2. Low climb mode

Odd thing is that I am currently running a test flying session offline just pummeling the engine (max power, max conditioner lever, CTOT to 110% during takeoff), with temperatures way above 971 for both engine. This test has been running for well over 30 minutes now, yet the engines haven't melted down yet...

I want to believe I did something wrong twice in my two online flights but I can't really get my head around why when being careful things go wrong & when being wreckless & pushing the engines, all goes well...

Thanks for the info, I will patiently wait for the next update to what is already a phenomenal piece of software.

As for the failures, I do quite enjoy them and the fact they keep me on my toes & require me to practice emergency procedures for when it does happen. Funnily enough, I tend to react to bugs in the same way I would to genuine failures.

I might have to video record/capture the flight next time round in case I need to go back & see where & when I went wrong. I have not seen any IVAO/X-IVAP/SAAB related conflicts/issues mentioned on the web and/or in this forum so it is unlikely there is any correlation but the fact that I was supposedly operating within the standard flight operations makes me skeptical. So far, I must have flown 10/20 flights offline since I bought the aircraft with no issues, whereas the only 2 online/IVAO flights I attempted have resulted in engine fires only a few minutes after takeoff (roughly in the same place & time)

As for my previous "stress-test", I kept the sim running for an extra 20 minutes or so (so about 40-50 minutes of deliberate engine stress), flying straight at 2500ft AGL with max power, max condition levers, engine temperatures above 980, torque & all dials in the red & beyond for the whole duration but nothing caught fire...

I have the same problem: when flying online/IVAO some time after takeoff burn one or both engines. I have disabled the failures in X-plane, but every fly online/IVAO i have a troubles with engines & equipment. For example, the engines can burns at any time and any conditions:  when my aircraft at FL200 at 50% torque, when descend at 30% torque, etc. It is impossible to me to understand when and why engines burn. Please help, what could be the reason?

XP11 or XP10?

Dayler,

Please post you log.txt file here so we can take a look at it.

Sorry for my posts, yesterday i found that the engines burns other aircrafts too. So this is the problem with my XPL/plugins, not your aircraft. I'll try to find out what the problem is and write here. Sorry again :)
