Bad combination of AB detents settings can lead to abnormal nozzles vs AB operation


Recommended Posts

Hi,

         Only after the latest updates which include a an otherwise very useful setting of controlling the AB detents as a % of throttles position, I've noticed that if you put an AB detent % summed with the deadzone % which would give a result of over 100, the engines will forever remain in FULL AB while the exhaust nozzles will correctly listen to the IAS-MACH-THROTTLE function and can go fully closed with the afterburners blasting at max gas flow rate, definitely proving an engine model fault, only due to this reaction of the nozzles which don't listen to engine regimes conditions, but only to throttle inputs and IAS/MACH function, not caring if the afterburners are in full demand! To cut any useless replies from the start, you never possibly can have a full afterburner condition with the nozzle fully closed without having the engine either get into a violent surge or eventually blowing off altogether.

Regards.

When you can't prove something with words, let the math do the talking.

I have an insatiable passion for helping simulated aircraft fly realistically. Don't underestimate my knowledge before understanding what I talk about!

This has probably already been fixed, there was a bug in sensed throttle positions with the new detent and deadzone setting. It will come out soon in the next patch.
