Controllable spool rate

I would like to be able to add a AIR_70_CORRECTED_N2_FROM_FF table to an aircraft with a turboprop engine and have that table be used just like it is in the turbine simulation to control spool rate.

This has become a major issue for us in production training systems for turboprop based aircaft.

I would have to agree with you. To be able to control the speed to which the starter spools the engine on a turbo-prop and actually have the slow prop spin without needing to change the PropellerMOI that would be a treat.

So "Aircraft.cfg" - Control of Fuel Flow at specific N1/N2 Rates and Spool time in seconds would be an awesome additional feature.

A previously undocumented capability is to configure your fuel_flow_gain in the aircraft.cfg to be a function of engine speed (N2 for straight turbines, N1 for turboprops). It might look something like this...

fuel_flow_gain.0 = 00.0, 0.011
fuel_flow_gain.1 = 25.0, 0.011
fuel_flow_gain.2 = 60.0, 0.05

You can configure up to 5 data points.

Hope this is helpful.
