engines would not power down and lower rpm for landing

[Ramstein]

engines would not power down and lower rpm for landing. I hit a bunch of targets, came in to land, and engines would not lower the engine rpm and power enough to land,, they engines would just throttle up by themselves when I tried to land. As if they refused to slow down, and let the plane slow down, they kept the plane at abround 200 mph.. no matter what I tried, they just would not slow down, and drop power... I had two choices, abort mssion and kil the mission, or try to manually shut down the engines in flight..

 

I could apply more throttle to turn around and keep trying more approaches, but could never get it drop below around 180mph on the runway (Anapa),, it would just keep trying to power back up..

 

what went wrong,, and the fuel gauges were just above the 1. (large 1 on the fuel dials)

 

thanx..

Maybe engine throttle is mapped to more than one axis?

Can you post a track? That will narrow down the guess work. It could be a list of things.

[Iceman2011]

I'd suggest u check your key bindings

[Ramstein]

problem hasn't come back, I flew some more and didn't have the problem come back... just more weird stuff..

What was the temperature of the mission?

 

You get a lot of fluctuations and unwanted thrust at extreme temperatures (can't remember if it were -50 or +50 celcius)

or try to manually shut down the engines in flight

 

As a small note, if they're being really troublesome, the easiest way to shut them down is to pull the fire handle for the affected engine. Note that fire handles do not set off the fire extinguishers (this is the separate switch to the right on the glare shield), what they do is that they sever the fuel supply to the engine. Not really the "textbook" way to do it, but it works. :P

 

Just make sure to do it when set up on a good key for gliding home, and make sure to jet your stores. Also, on a gliding landing, do not extend flaps early. (And maintain eyeball on hydraulic pressure to make sure you'll be able to get your gears out.)

 

Another possible thing to do would be to set both engine fuel flow switches to override, in case there's a malfunction in the engine governors, might solve the issue without having to turn them off. (Though you should of course still RTB under that condition.)

What's possible regarding engine-out landing (with 'good' engines) is that you start your APU and motor one of the engines to get hyd power. Though I believe not a textbook solution, still possible, but dependant on engine condition.

It's certainly not textbook, in fact it's only possible at all due to a bug. ;)

 

There should be no useable hyd pressure at all in a system if the engine that powers it is not operating.

 

Basically within seconds of an engine shutdown, you 'should' loose the corresponding hyd system. If and when the bug is fixed, be prepared to change your emergency procedures. ;)

I sort of figured this yes. But thanks for confirming that it is indeed a bug.

Where is a situation where you lose both hydraulic systems but engines are good? I have yet to use the manual reversion or whatever its called.

[Eddie]

It should be able to happen, either with random failures or battle damage. But to be honest I've not seen it either.

Only thing to do then is as you said, Manual Reversion.
