The feet given in the Pilot’s Operating Hand book (POH) are in density altitude or pressure altitude? I think its density altitude as we know that destiny altitude is used for performance. However, for example, altitudes shown in the aeronautical charts are given in MSL.
My POH says to start leaning once reach the 3000 feet, but it does not say in which type of feet (MSL), (Density altitude), (Pressure Altitude)
How can you determine what altitude the POH is talking about?
