Flight Crew
Who Does The Pre-Takeoff Contamination Inspection?
Ground Crew
Within how many minutes prior to takeoff must a pre-takeoff inspection or contamination inspection be done?
5 min
When is a Pre-takeoff Contamination Inspection Required?
When the Hold Over Time (HOT) has expired.
When is a Pre-takeoff Inspection Required?
When outside the Lower HOT.
When is a Pre-takeoff Inspection not required?
When within the Lower HOT.
Can FINAL APP Mode be used in Cold Weather Operations?
Not below minimum temp noted on chart. If no temp on chart, then not below 0°C.
What type of approach mode should be used for non-precision approach during cold weather operations?
SELECTED
FPA
At what point on an approach must FPA be cold weather corrected?
From the Final Decent Point (FDP)
When are crew required to make cold weather corrections?
The the airport OAT is 0°C or below.
When should the ice shedding procedure be applied?
Required when OAT is at or below +3° for more than 30 minutes.
How should ice shedding procedures be applied?
- OAT +3°
- conditions of freezing rain, freezing drizzle, freezing fog or heavy snow
- Increase engines (ground operations permitted) to 60% N1 for 30 seconds at intervals not greater than 30 minutes.
- additional runups at intervals, to not exceed 10 min
