BUG: Refueling Engine Auto-Start While Fuel Ran Out

[Worrazen]

When running out of fuel mid flight, the engines auto-start while refeuling which immediately stop refueling which makes me to wait for another 180 seconds once I shut them down manually.

 

I don't see the practical purpose unless the refueling wouldn't be stopped or at least the engines starting when the refueling is done.

just make sure to throttle down and kill engines after a deadstick landing. This would be the correct way of doing it IRL as well. ECU doesn't care -why- the engine shut down, if it sees commands that tell it to attempt restart, it will...

Okay, if extra-killing the already killed engines is going to work... maybe it does make sense, i'll try it.

the "stop engine" command does not kill the engine, nor does the "start engine" command start the engine.

 

A jet engine is not like a car engine. You, the pilot, have little to zero direct control over the operation of the engine in anything approaching a modern jet aircraft. The ADEC or FADEC receives your commands, interprets your intent, and then does what is needed to get the engine to operate as commanded.

 

What you are describing is a result of the F/ADEC seeing the engines die due to a drop in fuel pressure, and subsequently re-starting when fuel is available. The F/ADEC has no way of determining that the fuel simply ran out (it probably isn't even programmed to consider that a possibility). For all it knows, you had been performing sustained inverted maneuvers, which starved the fuel pumps. Since this likely -is- a programmed failure mode, the F/ADEC assumes that you wish to be able to fly your plane when you turn it back up the right way, and it re-starts the engines when it sees fuel pressure in the lines.
