R44 II Definitions

Knot indicated airspeed, shown on airspeed indicator

Knots calibrated airspeed: Speed shown on the airspeed indicator corrected for instrument and position error

Knots true airspeed: relative to undisturbed air, it is KCAS corrected for pressure altitude and temperature

Never exceed airspeed

Speed for best rate of climb

stabilized level-flight speed for maximum continuous power

Mean sea level: altitude above sea level indicated in feet by the altimeter, when the barometric subscale is set to the atmospheric pressure existing at sea level

Altitude in feet, indicated by the altimeter, when the barometric subscale is set to 29.92 Hg

Altitude in feet, in ISA conditions in which the air would have the same density

International standard atmosphere: pressure is 29.92 Hg at sea level, temperature at 15° C at sea level. and temperature decreases at 1.98° C per 1,000 feet of altitude

Brake horse power

Manifold pressure: absolute pressure in the engine intake manifold

Revolutions per minute

Maximum continuous power

Take-off power

altitude at which full throttle produces maximum allowable power

Take-off gross weight

Outside air temperature
