Unrealistic engine behavior at high altitudes
-
@lilycrose Remember, the tables are at max gross weight at ISA. Here's my flight at 55% power at near max gross weight in cruise as a test flight. OAT is bit below ISA for FL280 at -40C. My indicated TAS is about 220 knots so within 10 knots of the chart.
@Hawkeye That's interesting, are you at full throttle or setting the MAP? And I have a full fuel load but only 50 lbs of cargo and 120 lbs in the Pilot seat, so I can see the speed faster, but the fuel burn is much higher as well. And -40C is only 1 degree off standard day.

@lilycrose I’m using my throttle to set the power to the proper setting within the power charts. I’m demonstrating that the turbocharger is overperforming at high altitudes because when the proper power settings are achieved, the aircraft behaves as expected per the manual. TLDR: Turbocharger issue, not Flight Model Issue.
