LOW AIRSPEED AWARENESS SYSTEM
(Continued)
When the P/S HEAT/LOW A/S AWARE switch is turned ON prior to
takeoff, the BELOW ICING MIN SPD annunciator will be illuminated
white, indicating that the airspeed is below 97.5 + 2.2 knots. Once the
airspeed exceeds 97.5 + 2.2 knots, the BELOW ICING MIN SPD
annunciator will extinguish. If the airspeed falls back below 97.5 + 2.2
knots, the BELOW ICING MIN SPD annunciator will flash between
amber and white and the stall warning horn will sound intermittently
until the airspeed is increased above 97.5 + 2.2 knots.
Pressing the flashing BELOW ICING MIN SPD annunciator, which
incorporates a momentary switch, silences the stall warning horn and
causes the annunciator to stop flashing. The annunciator will remain
illuminated solid white as long as the airspeed is below 97.5 + 2.2
knots. The autopilot must be disengaged when the flashing amber and
white annunciation is activated.
The BELOW ICING MIN SPD annunciator brightness is controlled by
the LED PANELS/ANNUN rheostat located on the lower part of the
instrument panel to the left of the control pedestal. For daytime
operations the rheostat should be rotated full counter-clockwise to the
DAY position to make sure it is visible in bright light conditions. For all
other lighting conditions, the LED PANELS/ANNUN rheostat can be
adjusted clockwise to control lighting intensity.
