- inlet pressure
- i. The total pressure taken in the engine inlet as a measure of air density. This parameter is sent to the fuel control for fuel scheduling. It is normally known as P1 pressure.ii. As it relates to the performance data on pumps, when not otherwise specified, the total static pressure measured in a standard testing chamber by a vacuum gauge located near the inlet port. Also called intake pressure, fine pressure, or head pressure.
