Chapter 10 Winter Ops Flashcards
What is a Pre-Flight Critical Surface Inspection (CSI)?
A CSI is a pre-flight external visual inspection of the aircraft critical surfaces and engines conducted by a flight crew member to determine if the aircraft critical surfaces and engines are contaminated.
During ground icing conditions, is single engine taxi permitted?
No. The engine inlet, core, and fan blades shall be inspected prior to departure. During ground icing conditions, both engines should be started as soon as practicable after the engine inspection and should not be shut down prior to take-off.
During the walk around you discover contamination in the engine inlets, what should you do?
Failure to confirm that the engine areas are clear of contamination prior to engine start could result in an abnormal engine start due to lack of proper airflow.
If engine contamination is found, Flight Crew shall notify MOC via Flight Dispatch to coordinate the removal of the contamination with the appropriate stakeholder:
Do the cabin crew and passengers need to be briefed on de-icing?
The Pilot-in-Command shall inform the Cabin Crew and passengers that the aircraft will be de-iced. This advisory should normally be given at the gate prior to pushback but in all cases shall be done prior to de-icing
When does the flight crew read the de-icing check list?
The QRH de-icing checklist shall be referenced prior to the “Before Start Checklist”
How do you determine “active frost” conditions?
When the aircraft surface temperature cools to the frost point, frost will accrete on that surface (refer to Dew Point/Frost Point table under Guidelines / Active Frost in AC eHOT)
How cold of temperature can type IV fluid be used?
LOUT for Type IV Fluid at 100% concentration is at least -25°C, with the exception of the Dow Endurance EG106 Type IV Fluid (Canadian Stations, except for YHM) at 100% concentration where it is -29°C.
What is LOUT?
By definition, the LOUT for a specified fluid at any given temperature is the higher of:
- The lowest temperature at which the fluid meets the aerodynamic acceptance test for a given aircraft type; or
- The actual freezing point of the fluid plus its freezing point buffer of 10°C, for a Type I fluid and of 7°C for a Type II, III or IV fluid.
When preparing for on-gate de-icing, the brakes should not be released for the sole purpose of indicating an out time. How do you ensure the proper out time is recorded?
The Pilot-in-Command will communicate the departure time by sending an ACARS message to Flight Dispatch indicating such time using the following format: OUT hh:mm GATE DEICING
What is a PCI?
A PCI is an inspection of the representative surface(s), conducted by an operating flight crew member within five minutes prior to beginning the take-off roll.
How is a PCI conducted?
PCIs shall be carried out from a vantage point and under lighting conditions that permit an accurate assessment of representative surface(s). The inspection shall be conducted from inside the aircraft through an over-wing window or, if applicable for the station, from outside the aircraft by a qualified person.
What is a PDI?
Post-de-icing inspection. It is the responsibility of the service provider to complete the PDI following the completion of de-icing and/or anti-icing.
However, during single truck deice ops, the FO shall also perform a PDI immediately after completion of deicing.
Is a PCI required if a PDI has been completed?
Depends. A PCI is not required when the take-off is conducted within five minutes following a PDI.
How do you signal an emergency to the de-icing ground crew during de-ice ops?
Emergencies shall be signaled to ground service equipment during spray operations by turning on all exterior lights (wide body aircraft shall use all exterior lights except for landing lights)
What do you use if ACARS HOTDR is not available?
When ACARS communications are not available or the HOTDS (both LWE and METAR based) is unserviceable for the departure airport, Flight Crews shall use the AC eHOT app (sureWx) to determine HOT.
