IPT 4

Question 1

What checklist should you use when in Icing conditions?

Answer 1

Use the deicing/ anti-icing confit checklist in QRH BECAUSE ITS REQUIRED

Question 2

What does the term “Cold Soaked” mean ?

Answer 2

• 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

Question 3

What is a contaminant ?

Answer 3

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

Question 4

What qualifies as a contaminant ?

Answer 4

Snow
Frost
Ice 
Slush
Freezing precipitation

Question 5

What are the critical surfaces of the plane when it comes to icing?

Answer 5

Upper/Lower wing surfaces
Control surfaces (flaps, ailerons, spoilers)
Winglets
Horizontal stab
Vertical stab
Fuselage 
Engine inlet

Question 6

What type of fluid is a DE-ICE ?

Answer 6

TYPE 1

Type 3

Question 7

What are the most critical types of freezing precipitation?

Answer 7

Freezing Drizzle 
Freezing Rain
Freezing Fog
Ice Pellets
Small Hail
Sleet or Grains of Ice

Question 8

When is a runaway considered wet?

Answer 8

Shiny appearance due to thin layer of water

Not more than 1/8th inch of depth though

Question 9

What is considered standing water on the runway?

Answer 9

More than an eighth of an inch of water depth on the runway

Question 10

What is considered a contaminated runway?

Answer 10

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

Question 11

How would you determine that you were in SLD icing conditions?

Answer 11

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

Question 12

Are you required to leave SLD icing conditions?

Answer 12

Yes immediately

Question 13

If you have to abort takeoff after being de-iced is your holdover time considered exceeded?

Answer 13

Yes due to shearing of the fluid off the wings you will need to be iced again

Question 14

If icing conditions are expected below 1700 AGL what should be selected?

Answer 14

ENG REF ANTI-ICE to the ON position

Question 15

If icing conditions exist, what position should the Ice Detection Override switch be in?

Answer 15

Selected to ENG during the normal AFTER START FLOW

Question 16

When should you select the engine ignition to the ON position for take-off?

Answer 16

If there is:

Standing Water
Ice
Slush
Snow

On the runway

Question 17

What EICAS messages might you see at low thrust in icing conditions ?

Answer 17

STAB A/ICE FAIL
WG A/ICE FAIL
ANTI-ICING LOW CAPACITY

Question 18

What are the key points of the departure briefing ?

Answer 18

T- threats
E-Emergencies
R-Ramp/Taxi
D-Departure procedure

Question 19

What situations are considered an abnormal start?

Answer 19

1. NO LIGHT OFF (ITT doesn’t RISE) within 10 seconds after first fuel flow indications (on ground only)
2. ITT approaches start limit (800C)
3. N2 decreases or remains steady for more than 30 seconds ➡️(HUNG START)🍩
4. N2 indicates no rotation up to 10 seconds after the start command
5. Any unusual noise or vibration
6. Engine instruments indicate abnormal conditions
7. Flames are visible from exhaust pipe
8. Oil pressure does not reach at least 34 PSI after the engine reaches stabilized idle

Question 20

How would you perform a DRY MOTORING procedure?

Answer 20

1. Reset FADEC and confirm it resets properly if NOT, do not proceed
2. Thrust levers to IDLE
3. Ignition to OFF
4. Start/Stop Selector goes to RUN-START-RUN for 1 minute on cycles 1-5

Minimum of 30 seconds Dry Motoring*

Question 21

What would you do if you received an ENGINE FUEL LOW TEMP message on EICAS when you’re on the ground?

Answer 21

Check that the ICING INHIBITOR has been added to the fuel

Question 22

What is the proper order of communications off the gate?

Answer 22

•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.
