Selkirk College IATPL Program Manual
Beech 95 POH Effective September 1, 2005 Appendix 14 - 14
(a) all engines developing maximum rated power at the time of critical engine
failure;
(b) the aeroplane at minimum take-off weight and in a rearmost centre of
gravity; and
(c) landing gear retracted, flaps in take-off position, and the propeller of the
failed critical engine windmilling.
Intentional One Engine Inoperative Speed - a speed above both (V
mc
) and stall speed,
selected to provide a margin of lateral and directional control when one engine is
suddenly rendered inoperative. Intentional failing of one engine below this
speed is not recommended.
Meteorological Terminology
Outside Air Temperature is the free air static temperature. It is expressed
in degrees Celsius.
Standard Temperature is 15 C at sea level pressure altitude and decreases
1.98 degrees per thousand feet.
Pressure altitude is the altitude read from an altimeter when the altimeter
barometric scale has been set to 29.92 inches of mercury.
Density Altitude is pressure altitude corrected for non-standard air
temperature.
Engine Power Terminology
Brake Horsepower is the power developed by the engine
Revolutions per Minute is engine speed.
Is absolute pressure in the engine intake manifold in units of inches of
mercury.
Airplane Performance and Flight Planning Terminology
Useable Fuel is the fuel available for flight planning
Unusable Fuel is the quantity of fuel that can not be safely used in flight.
Gallons Per Hour is the amount of fuel in gallons consumed per hour.
Nautical Miles per Gallon is the distance in nautical miles that can be
expected per gallon of fuel consumed at a specific engine power and or
flight configuration.
g is acceleration due to gravity
