And that you have read the right altitude/temperature figures on the MAP chart, and appreciated that there is the section on the MAP chart labelled ‘full throttle’ when you are no longer gearbox/drivetrain/torque limited, but limited by the fact the engine won’t give anymore... i.e. instead of having a theoretical max, you will have an actual maximum engine power available with no specified figure (you won’t get the extra 2.8” take-off power), and you need to establish what that actual maximum power available is. Admittedly this is only an issue at higher altitude if you have a healthy engine/mags/gauge*, but that is precisely where it is really going to matter. It’s a wake up call when you start getting droop at 21” and you are used to being able to pull 25.5”, particularly if you are not prepared and expecting it!
