ITT do not behave as it should with altitude

Some customers have commented that the ITT behavior is not as it supposed to, that the ITT should increase as the altitude is increased, this behavior is true in all flat rated turboprops, controlled by an engine management computer, but in the turboprop engines in FS are not controlled by an engine management computer, and in turboprops engines not flat rated this behavior is correct, the ITT decreases as altitude is increased. The flat rated behavior may be simulated by forcing some values to show what it supposed to, but this will not affect the engine performance. This is why we don't simulate the ITT behavior in flat rated turboprop engines.
