N/A
15
Q
The Cold Wx Preflight Inspection Must be Performed when:
A
- OAT is ≤5℃ or
- Wing Fuel Temp is ≤0℃ or
- Atmospheric conditions conducive to icing exist or
- A/C has remained overnight and may have frozen contaminants due to exposure to frost or precip or
- Through flight with residual ice accumulated
- Cold soak is suspected in fuel tank area
