Is takeoff permitted with frost, ice, snow or slush adhering to any critical areas for takeoff?
No, with 2 exceptions:
- Max of 1/8” frost on underside of wing if it’s due to chilled fuel in the fuel tank
- Upper surface of fuselage may be frosted if surface features are distinguishable

15 minutes
If the primary wing NAV light burns out, how is the secondary bulb selected?
The secondary bulb will illuminate automatically
When the seatbelt sign switch is in the AUTO position, when will the seatbelt sign illuminate automatically?
When the landing gear or flaps extend, or when the cabin altitude exceeds 10,000 feet
What sends the signal for the seatbelt light to illuminate when the cabin altitude exceeds 10,000 feet?
The CPAM (Cabin Pressure Acquisition Module)
