Study Questions and Answers14
airspeed indicator - ANSWERS-a sensitive differential pressure gauge that measures and
promptly shows the difference between pitot (impact) pressure and static pressure, the
undisturbed atmospheric pressure at level flight.
The Four Airspeed Types - ANSWERS-ICE-T
1. Indicated airspeed
2. Calibrated airspeed
3. Equivalent airspeed
4. True airspeed
Indicated airspeed - ANSWERS-measures air pressure reading from the pitot tube
Calibrated airspeed - ANSWERS-airspeed calculated after accounting for aircraft mechanical and
position errors(altitude)
Equivalent airspeed - ANSWERS-airspeed calculated after compensating for compression effects;
usually only needed at speeds over 200 mph
true airspeed - ANSWERS-airspeed calculated after accounting for temperature and atmospheric
pressure changes
white arc - ANSWERS-commonly referred to as the flap operating range, since its lower limit
represents the full flap stall speed and its upper limit provides the maximum flap speed.
Approaches and landings are usually flown at speeds within the white arc.
, lower limit of white arc (Vso) - ANSWERS-the stall speed or the minimum steady flight speed in
the landing configuration. In small airplanes, this is the power-off stall speed at the maximum
landing weight in the landing configuration (gear and flaps down)
upper limit of the white arc (Vfe) - ANSWERS-the maximum speed with the flaps extended
Green arc - ANSWERS-normal operating range of the airplane; most flying occurs within this
range
lower limit of green arc (Vs1) - ANSWERS-the stall speed or minimum steady flight speed in a
specified configuration; for most airplanes, this is the power-off stall speed at the maximum
takeoff weight in the clean configuration (gear up if retractable, and flaps up)
upper limit of green arc (VNo) - ANSWERS-the maximum structural cruising speed; do not
exceed this speed except in smooth air.
yellow arc - ANSWERS-caution range; fly within this range only in smooth air, and then only with
caution
fixed-wing aircraft structure - ANSWERS-1. Fuselage
2. Wings
3. Tail assembly or empennage
4. Landing gear
5. Powerplant
6. Flight instruments/controls and control surfaces
