Loss of engine control above Mach 1.2?

[HawkDCS]

Seems like once your over Mach 1.2 you cant bring engines down in RPM just select A/B on and off? Is this just normal for the engines to stabilize thrust or is this a bug.

 

Feel free to test if you take bird up to Mach 1.5 FL350 then idle throttles the A/B turns off but turbines stay 99% till you slow down quite a bit.

 

Is this normal? Does it have some thing to do with 18 not having intake ramps?

Couldn't tell you the actual engine schedule, but yes, not uncommon to have higher RPM maintained at high airspeeds for stall prevention.

 

1-2-2 of the RL flight manual if you are inclined to read about it.

Here is the link so you can see what Rainmaker is referring to.
