rely on the flight manual for guidance.
"Guidance"?
"Guidance"?
Unbeliever! The manual is the Bible!
Thou shalt set the EGT needle to the divine number and, yea and verily, the EGT for each cylinder shall be so and thine engine shall be safe. Any other number shall be heresy and unsafe!
Thou shalt not suggest that 25 degrees C ROP or its F equivalent was a number chosen by the manufacturers' marketing department, because that number just about coincides with peak power and the fastest the aircraft will cruise, back in an era when competition between each new model put out by manufacturers was won and lost on a couple of knots. Thou shalt not suggest that the objective data show that setting mixture to 25 degrees C ROP is about the worst place for your engine, because that EGT just about coincides with the hottest CHT.
Give 'er a thrashing at 25 C ROP - that'll muster the hottest CHT you can - and have faith in the manual.
