after a 1 hour flight short bevor landing the C172 (with enough Fuel , no failures in sim Settings) just went off-Engine is off. all Other systems running. Couldn’t turn it on again. why? i crashed …
Carburetor icing is a possibility…

2300 Feet in Aalborg, Denmark, 12 Celsius now, was at 6000 the whole flight coming from south.
You’re prolly right, but keep in mind that carburetor icing can occur at pretty much any temperature in high humidity, as the flowing air in the carburetor is typically 40C below ambient, I think.

Well 12 Celsius live weather live time, day was like 20 Celsius pure sun.
hmm thats interesting wish theres a log or something that tells me what went wrong
40C is a bit much or? means with 40 plus in 500 Feet flight in africa i must anti ice..

Yes! It is standard practice for pilots to always turn on carb heat (at least temporarily) before any reduction in power (throttling back), no matter what the temperature, even if it’s 40C outside. You should add this to your routine, every real world pilot does that…

The 172 in Flight Sim is fuel injected. There’s no carb heat. Or am I missing something?

yeah thanks i guess the 6000 feet was enough . i just read about it when high pressure area is even more.
hmm dont know, then why where the engine going off suddenly with enough fuel. i tried all the 60 seconds before i crashed. all switches or levelers..
not another bug please…
Ah, ok, did not know that…
That’ll bite you on the 152 because it has a carburetor, but not a fuel injected 172. Lots of things can cause the engine to quit though. Too lean? Did you lean the mixture at cruise and then descend without putting it back to rich? Fuel starvation (as opposed to exhaustion?). Have to check the fuel selector and shutoff switches. Mags get switched off? If it happens again, I’d pause the sim and check to see if anything changed on your panel in that regard. Sometimes a controller conflict could cause an issue like this, where you’re inadvertantly changing something and not realizing it. Or you click on the panel by mistake.

Thanks , but nothing like that. i did not lean. all switches where good. i tried to move the fuel switch and all other levelers and switches in case of a bug and tried to get the engine on again.. nothing.
i didn pause the sim.
engine went just off..with half of fuel in both tanks left.
Full throttle and full mixture…
but the 172 has a carbon heat switch i did not touch this …??
The only other things i can think of are if failures were armed in the realism settings. And there was also an issue where controls were getting reset to a default state after pausing the sim, pressing escape, task switching, or plugging in a controller. If the USB connection is loose it might inadvertently reconnect a controller and do that too.
Otherwise, I’d say it’s a good time to practice best glide and and dead stick landings!

hehe yeah … i clicked all the switches and levelers with mouse so it cant be my joystick or throttle…i mean it can Asobo has so many bugs in this sim…sure its not the carb heat switch? i mean why is it there if its a fuel injected engine?
edit..found a german version of a checklist for the 172 Skyhawk (thats the one ingame right?)
it says to operate the carburetor heat…so its in this plane
That manual was likely for a 172M model or older, when a carbureted engine was still the standard, since the 172R they’ve come standard with fuel injected engines so there’s no carb heat control.

This actually depends on the aircraft.
I used to own a 1964 Cessna 172, and in it’s POH (Pilot Operating Handbook) it stated to introduce carb heat with any reduction in power.
I now have a 1973 Piper Cherokee 180, and directly from it’s POH in the “Approach and Landing” section states “Carburetor heat should not be applied unless there is an indication of carburetor icing, since the use of carburetor heat causes a reduction in power which may be critical in case of a go-around.”

You’ve got a carb heat switch in your 172? (It’s usually a pull out knob like the throttle). Screenshot please. Or did you mean the pitot heat or cabin heat? Or did you mean the 152?
In the 172, on Xbox. Just around 23%, engine cut off, but no failure armed from menu. I saw the turn on engine button combo and I pressed them which had the engine running again. After an hour of flight.
