Whenever the icing AOA is illuminated the aircraft is protected by an earlier stall threshold as follows: |
Both the stall alert and stick pusher thresholds are modified |
|
|
Aircraft ice protection is provided by: |
Electrical heating and pneumatic boots |
|
|
In normal operating conditions, what NP is required for the propeller anti icing system? |
NP above 63% |
|
|
During Hotel mode operation, with the probes and windshield heating both switched ON, what items are heated? |
Static ports and STBY pitot |
|
|
Electrical current for anti-icing is provided by the ACW system for: |
Propeller blades Windshields Pitots Flight control horns |
|
If there is fault with the de/anti icing automatic mode, when should the DE ICING manual mode push button be selected to SLOW? |
When SAT is below - 20°, causes a cycle length of 180 seconds |
|
|
With both the airframe and engine de-icing selected on, they are: |
De-iced sequentially |
|
|
With OEI, are both sides of the airframe de-icing system supplied? |
Yes |
|
|
What things are protected pneumatically? |
- outer, center, and inner wing leading edges - horizontal tailplane leading edges - engine air intakes and gas paths |
|
|
What systems are protected electrically? |
- propeller blades - windshields - probes - flight control horns |
|
|
With the bleeds turned off, will the pneumatic system still supply bleed air for de-icing? |
Yes |
|
|
Where is the ice detector? |
Under the left wing |
|
|
What temperature does clear ice form? |
2 and - 10 |
|
|
What temperature does rime ice form? |
-15 to - 20 |
|
When would you use the guarded switch? |
When both MFC modules are lost, FAULT light will be on. Switch to OVRD in this instance (activates emergency de-icing) |
|
|
Are static ports monitored by the FWS? |
No |
|
|
What three things are required to alert the APM provided SAT is below - 10? |
- icing AOA illuminated - de icing airframe pb selected on - ice accretion was detected at least once during flight |
|
|
When is APM alert CRZ SPD LO generated? |
When speed is 10kts lower than the theoretical minimum drag speed |
|
What is the normal state for the de-icing mode select Pb? |
Pushbutton released |
