[CORRECT AS IS] Maximum RPM at high altitude?

While trying the Viper I realised that around 30k ft the max RPM is around 95%, both with and without afterburner. This happens both in today's beta as well as the previous version.

 

Is this the expected behaviour?

 

Yes, Also After Burner (AB) should not affect RPM. RPM is not set and depends on many factor. The only thing to worry about is make sure RPM does not exceed 108% (plus or minus 1%) But AFAIK, nothing says RPM should be a specific number.

 

Obviously if you have throttle all the way forward to max AB and you only have 25% RPM, that is different. But 90% to 106% RPM at mil power and above I would consider normal.

To whom it may concern,

I am an idiot, unfortunately for the world, I have a internet connection and a fondness for beer....apologies for that.

Thank you for you patience.

100% RPM is based on the design engine limitations. Because turbine engines spin at ~25,000 RPM it's pointless to show the actual engine speed, so the gauge depicts a percentage. The engine will still spin more slowly than this 100% rated RPM at high altitude for the same reasons that all engines produce less power at altitude.

Interestingly the RPM changes significantly even at low altitude in the F16.

100% <300ktias, 102% from 400 to 500kias and 97% at 900kias.

 

On the F-5 the RPM doesn't change with speed at low alt.
