If both wing and engine anti ice valves are open and then closed what happens to the stick shaker logic? |
Stick shaker logic will be set based on icing conditions |
|
|
If ONLY engine anti ice valves are open and then closed what happens to the stick shaker logic? |

|
|
On the wings what surface is heated? |
3 leading edge slats on both sides |
|

|
What indication on the DU will tell you the Cowl Anti Ice is ON? |
A green TAI will display above the N1 |
|
|
When does EAI need to be used in flight and how would you turn it on? |
Flight in icing conditions when ice build up is occurring on windshield blades including tempretures <-40.
To turn on; Engine Start Switches....CONT (PM) EAI Switches....ON (PM)
To turn off; EAI Switches....OFF (PM) Engine Start Switches....OFF (PM) |
|
|
When would WAI need to be used in flight and how would you turn it ON/OFF? |
Icing conditions (+10TAT - -40C SAT) with ice buildup on the windshield/windshield blades
To turn on; Wing Anti Ice Switch....ON (PM)
To turn off; Wing Anti Ice Switch....OFF (PM) |
|
|

10 minutes |
|
|
What indication do you get if there is a window overheat? |
