SR20 Airplane Description
Airspeed Indicator
• Note •
Serials 1337 and subsequent: The standby airspeed indicator
is mounted on the LH bolster panel and shows only indicated
airspeed.
Indicated and true airspeeds are indicated on a dual-scale, internally
lit precision airspeed indicator installed in the pilot’s instrument panel.
The instrument senses difference in static and Pitot pressures and
displays the result in knots on an airspeed scale. A single pointer
sweeps an indicated airspeed scale calibrated from 40 to 220 knots.
The ‘zero’ index is at the 12 o’clock position. A sub-scale aligns true
airspeed with the corresponding indicated airspeed when the altitude/
temperature correction is set in the correction window. A knob in the
lower left corner of the instrument is used to rotate the pressure
altitude scale in the correction window to align the current pressure
altitude with the outside air temperature.
Vertical Speed Indicator
• Note •
Serials 1337 and subsequent: The Vertical Speed Indicator is
integrated into the PFD.
Airplane rate of climb or descent in feet per minute is displayed on the
internally lit Vertical Speed indicator installed in the pilot's instrument
panel. The instrument senses rate of change in static pressure from a
reference pressure and displays the result in climb or descent feet per
minute (FPM). Climb is indicated by clockwise rotation of the pointer
from zero and descent is indicated by counter clockwise rotation. The
'0' (zero) reference point is at the 9 o'clock position. The scale is
calibrated from 0 to 2000 FPM in 100-FPM increments in both the 'UP'
and 'DOWN' directions.
