Anti-Ice System Failure / Excessive Ice Accumulation
1. ICE PROTECT A and B Circuit Breakers................................. SET
2. Fluid Quantity................................... SWITCH TO FULLEST TANK
3. WIND SHLD Push-Button...................................................PRESS
a. Repeat operation of windshield pump to verify metering
pumps are primed properly as evidenced by deicing fluid
exiting windshield nozzles.
4. ICE PROTECT Mode Switch ................................... VERIFY HIGH
5. PUMP BKUP Switch ..................................................................ON
If determined windshield pump is not priming:
6. Exit Icing Conditions Immediately.
7. Airspeed.....................................................95 KIAS OR GREATER
Maintain a minimum airspeed of 95 KIAS or higher to stay above
pre-stall buffet. If unable to maintain this airspeed, allow altitude to
decrease in order to maintain 95 KIAS.
8. Minimum Approach Speed w/ Residual Ice (Flaps 50%)...88 KIAS
In severe icing conditions, it may not be possible to maintain
altitude or proper glide path on approach; in this case, it is
imperative that a safe airspeed be maintained, the stall warning
system may not function and there may be little or no pre-stall
buffet with heavy ice loads on the wing.
9. FLAPS ........................................................ MINIMUM REQUIRED
When landing is assured, select the minimum flap setting
required, not to exceed 50%, and maintain extra airspeed
consistent with available field length. Do not retract the flaps once
they have been extended unless required for go-around.
