@stefan_jat Pressure altitude was around 15,000ft. Density altitude around 17,000ft. The weight was at about 80% of full load.
The maximum allowed MP is 41in, but the maximum MP goes higher than that at sea level, hence the need for an overboost warning. Also, maximum pressure should and does go down with altitude. My question is if 36in of MP is normal at 15,000ft.
Thank you.
