Power off stalling speed or the minimum steady flight speed at which the aircraft is controllable.
Stalling speed or the minimum steady flight speed in the landing configuration.
The safe one-engine inoperative speed selected to provide a reasonable margin against the
occurrence of an unintentional stall when making intentional engine cuts.
Best angle of climb speed.
best single-engine angle of climb speed.
Best rate of climb speed.
The best single engine rate of climb speed.
The indicated airspeed the aircraft should be at when 50 feet above the runway in landing
One-engine-inoperative enroute climb speed.
Barometric pressure corrected to sea level.
Free air temperature is the free air static temperature, obtained either from ground
meteorological sources or from inflight temperature indications adjusted for compressibility
The number actually read from an altimeter when, the barometric scale (Kollsman
window) has been set to 29.92 inches of mercury (1013 millibars).
International Standard Atmosphere in which:
The air is a dry perfect gas:
The temperature at sea level is 59 degrees Fahrenheit, 15 degrees Celsius;
The pressure at sea level is 29.92 inches Hg;
The temperature gradient from seal level to the altitude at which the temperature is -69.7
degrees Fahrenheit is -0.003566 Fahrenheit per foot and zero above that altitude.
Indicated pressure altitude corrected for altimeter error.
The wind velocities recorded as variables on the charts of this manual are to be understood as
the headwind or tailwind components of the actual winds at 50 feet above runway surface (tower
