2.3.2.2. Airspeed Tape and Bug
Airspeed is indicated by a moving airspeed tape against a fixed position airspeed
pointer, shown on the left-hand side of the Attitude Display (
Figure 2-30
). A numerical,
rolling drum readout indicating airspeed values to the closest one knot or mile per hour
is provided adjacent to the fixed pointer. Tick marks are provided on the airspeed tape
every 10 knots (or mph, if so configured). Airspeeds between 20 kts (23 mph) to 450 kts
(518 mph) are displayed. Outside of this range, the airspeed value is dashed.
Color speed bands are displayed on the indicated airspeed tape, corresponding to the
color arcs found on a mechanical airspeed indicator. All helicopters have a red line for
Power On (Vne). Red/ White Power off line, and a blue line for max auto rotation speed.
Redline airspeed limits that vary with pressure altitude can be displayed when
configured by the installer. The colors are configured to correspond with your aircraft’s
approved markings on the mechanical airspeed indicator.
