3.3. ENGINE POWER TERMINOLOGY
MCP Maximum Continuous Power is the maximum power for abnormal or emergency operations.
BHP Brake Horsepower is the power developed by the engine.
RPM Revolutions Per Minute is engine speed.
Static RPM Static RPM is engine speed attained during a full throttle engine run up when the
airplane is on the ground and stationary.
3.4. AIRPLANE PERFORMANCE AND FLIGHT PLANNING TERMINOLOGY
DCV Demonstrated Crosswind Velocity is the velocity of the crosswind component for which
adequate control of the airplane during takeoff and landing was actually demonstrated
during certification tests. The value shown 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 100 ft/min.
GPH Gallons Per Hour is the amount of fuel consumed per hour.
FPM Feet Per Minute is the distance, in feet, travelled over the duration of one minute.
g One “g” is a quantity of acceleration equal to that of earth’s gravity.
T/O Take off
3.5. WEIGHT AND BALANCE TERMINOLOGY
Reference Datum Reference Datum is an imaginary vertical plane from which all horizontal distances
are measured for balance purposes.
C.G. Center of Gravity is the point at which an airplane would balance if suspended. Its
distance from the reference datum is found by dividing the total moment by the total
weight of the airplane.
Arm Arm is the horizontal distance from the reference datum to the center of gravity (C.G.)
of an item. The airplane’s arm is obtained by adding the airplane’s individual moments
and dividing the sum by the total weight.
Moment Moment is the product of the weight of an item multiplied by its arm.
C.G. Arm Center of Gravity Arm is the arm obtained by adding the airplane's individual moments
and dividing the sum by the total weight.
C.G. Limits Center of Gravity Limits are the extreme center of gravity locations within which the
airplane must be operated at a given weight.
MAC Mean Aerodynamic Chord is a chord of an imaginary rectangular airfoil having the
same pitching moments throughout the flight range as that of the actual wing.
Standard
Empty
Weight
Standard Empty Weight is the weight of a standard airplane, including unusable
fuel, full
operating fluids and full engine oil.
Basic Empty
Weight Basic Empty Weight is the standard empty weight plus the weight of optional
equipment.
Payload Payload is weight of occupants, cargo and baggage.
Maximum
Takeoff
Weight Maximum Takeoff Weight is the maximum weight approved for the start of the
takeoff roll.
Maximum
Landing
Weight Maximum Landing Weight is the maximum weight approved for the landing
touchdown.
Useful Load Useful Load is the difference between basic empty weight and maximum takeoff
weight.
