Performance and Flight Planning Terminology
• Standard Temperature is the temperature that would be
found at a given pressure altitude in the standard
atmosphere. It is 15° C (59° F) at sea level pressure altitude
and decreases approximately 2° C (3.6° F) for each 1000
feet of altitude increase. See ISA definition.
HP Horsepower is the power developed by the engine.
MCP Maximum Continuous Power is the maximum power that
can be used continuously.
MAP Manifold Pressure is the pressure measured in the
engine’s induction system expressed as in. Hg.
RPM Revolutions Per Minute is engine rotational speed.
• Static RPM is RPM attained during a full-throttle engine
runup when the airplane is on the ground and stationary.
g One “ g ” is a quantity of acceleration equal to that of earth’s
gravity.
• Demonstrated Crosswind Velocity is the velocity of the
crosswind component for which adequate control of the
airplane during taxi, takeoff, and landing was actually
demonstrated during certification testing. Demonstrated
crosswind is not considered to be limiting.
• Service Ceiling is the maximum altitude at which the
aircraft at maximum weight has the capability of climbing at
a rate of 100 feet per minute.
GPH Gallons Per Hour is the amount of fuel (in gallons)
consumed by the aircraft per hour.
NMPG Nautical Miles Per Gallon is the distance (in nautical miles)
which can be expected per gallon of fuel consumed at a
specific engine power setting and/or flight configuration.
