Airspeed Indicator
a.
Under standard atmospheric conditions at sea level, the airspeed indicator (Figure 1­5)
shows the speed at which the airplane is moving through the surrounding air mass. The
pointer is activated by the difference in pressure between static air pressure and the
impact air pressure from the pitot tube. The face of the instrument is calibrated in
knots. The airspeed indicator provides a continuous indication by which you can
maintain flight within safe minimum and maximum airspeed limits for various
performance conditions. Refer to NATOPS for additional information.
b.
Use and Limitations. The airspeed indicator is the nose attitude crosscheck
instrument in all climbs and descents and a performance instrument in level flight. It
will give you an indirect indication of nose attitude with a constant power setting. For
any particular power setting, there is only one nose attitude that will hold altitude and
airspeed constant for any momentary weight. The airspeed is controlled by power
during level flight and by nose attitude during a climb or descent. Since the airspeed
indicator is a pitot­static instrument, there is a slight lag (2­3 knots) when
accelerating or decelerating. Realize also that the airspeed indicator lags behind nose
movement in climbs and descents, so when correcting for airspeed in a climb or
descent, reference the gyro for miniature aircraft nose movement and allow sufficient
time for the airspeed to react prior to initiating another nose attitude correction.
