IPT 4 Flashcards
(22 cards)
What checklist should you use when in Icing conditions?
Use the deicing/ anti-icing confit checklist in QRH BECAUSE ITS REQUIRED
What does the term “Cold Soaked” mean ?
- wings contain fuel that is very cold due to flying at high altitude in cold temps.
- wings have been filled with very cold temperature fuel
What is a contaminant ?
Any type of substance that when in contact with the critical surfaces of an aircraft causes a degradation of lift or operation of those surfaces
What qualifies as a contaminant ?
Snow Frost Ice Slush Freezing precipitation
What are the critical surfaces of the plane when it comes to icing?
Upper/Lower wing surfaces Control surfaces (flaps, ailerons, spoilers) Winglets Horizontal stab Vertical stab Fuselage Engine inlet
What type of fluid is a DE-ICE ?
TYPE 1
Type 3
What are the most critical types of freezing precipitation?
Freezing Drizzle Freezing Rain Freezing Fog Ice Pellets Small Hail Sleet or Grains of Ice
When is a runaway considered wet?
Shiny appearance due to thin layer of water
Not more than 1/8th inch of depth though
What is considered standing water on the runway?
More than an eighth of an inch of water depth on the runway
What is considered a contaminated runway?
A runway is considered to be contaminated when more than 25% of the runway service area within the required length and width being used is contaminated
How would you determine that you were in SLD icing conditions?
The flight deck side windows will give you the proper indication. If any ice accumulates on cockpit side windows you should assume that SLD icing conditions are present
Are you required to leave SLD icing conditions?
Yes immediately
If you have to abort takeoff after being de-iced is your holdover time considered exceeded?
Yes due to shearing of the fluid off the wings you will need to be iced again
If icing conditions are expected below 1700 AGL what should be selected?
ENG REF ANTI-ICE to the ON position
If icing conditions exist, what position should the Ice Detection Override switch be in?
Selected to ENG during the normal AFTER START FLOW
When should you select the engine ignition to the ON position for take-off?
If there is:
Standing Water
Ice
Slush
Snow
On the runway
What EICAS messages might you see at low thrust in icing conditions ?
STAB A/ICE FAIL
WG A/ICE FAIL
ANTI-ICING LOW CAPACITY
What are the key points of the departure briefing ?
T- threats
E-Emergencies
R-Ramp/Taxi
D-Departure procedure
What situations are considered an abnormal start?
- NO LIGHT OFF (ITT doesn’t RISE) within 10 seconds after first fuel flow indications (on ground only)
- ITT approaches start limit (800C)
- N2 decreases or remains steady for more than 30 seconds ➡️(HUNG START)🍩
- N2 indicates no rotation up to 10 seconds after the start command
- Any unusual noise or vibration
- Engine instruments indicate abnormal conditions
- Flames are visible from exhaust pipe
- Oil pressure does not reach at least 34 PSI after the engine reaches stabilized idle
How would you perform a DRY MOTORING procedure?
- Reset FADEC and confirm it resets properly if NOT, do not proceed
- Thrust levers to IDLE
- Ignition to OFF
- Start/Stop Selector goes to RUN-START-RUN for 1 minute on cycles 1-5
Minimum of 30 seconds Dry Motoring*
What would you do if you received an ENGINE FUEL LOW TEMP message on EICAS when you’re on the ground?
Check that the ICING INHIBITOR has been added to the fuel
What is the proper order of communications off the gate?
•Contact RAMP for pushback
- mention Flt# and SID
- Expect taxi to a spot then contact METERING 19.95/28.1
- Contact METERING with spot number when ready to Taxi, expect to monitor GROUND.
