Emergency Procedures/Lost Comms

Question 1

What is the purpose of lost comms procedures?

Answer 1

To remain as predictable as possible to ATC

Question 2

What altitude should you fly if you’ve lost communication with tower?

Answer 2

Flight the highest of “MEA”
- MEA
- Expected altitude
- Last assigned altitude by ATC

Question 3

What route should you fly if you lose comms with tower?

Answer 3

“AVE-F” (select the course in this order)

1. Assigned route
2. Vectored
3. Expected
4. Filed route

Question 4

How does ice cause roll upsets?

Answer 4

• Ice accumulates forward of the ailerons particularly in SLD conditions.
• During slow speeds associated with approach and landing is most common to have this anomally

Question 5

How can pilots remedy roll upsets?

Answer 5

• Reduce AOA by increasing airspeed or extending wing flaps to the first setting if at or below VFE.
• If in a turn, wings should be rolled level
• Set appropriate power and monitor the airspeed and AOA
• If flaps are extended do not retract them unless it can be determined that the upper surface of the airfoil is clear of ice. Retracting flaps will increase the AOA at a given airspeed
