Why does the Emergency/Parking Brake need to be on prior to starting the external inspection?
To check the brake wear indicators.
Just because the parking brake is on, does this guarantee there is sufficient hydraulic pressure to check the brake wear indicators?
No
Hydraulic 1 and 2 must be pressurized
If the hydraulic pressure is depleted for the brakes, how can it be restored prior to the external walk around?
Activation of system 1 and 2 hydraulic pumps.
On the external inspection, you notice that the air data smart probes are covered in frost. What would be an appropriate action by the pilot?
Turn the ADSP Heater Switch to ON to remove frozen contaminants.
When parked aircraft have been exposed to freezing conditions, moisture can freeze inside the ADSPs and create undesired indications on the ground.
When airspeed indication is present on the PFD’s what messages may be displayed?
AFCS FAULT
AT FAIL
AP FAIL
FD FAIL
YD FAIL
APPR 2 NOT AVAIL
When is the ADSP Heater button pushed out?
After engine start, after Hydraulic Sys 1 pump is turned off.
Provide at least one other condition that would require heat being applied to the ADSPs during preflight.
OAT is at or below freezing and water, ice, or snow is present or suspected
On the first flight with temperatures below -18C
Smart Probes frozen
Eroneous airspeed indications present on the PFD with the following EICAS messages:
AFCS FAULT
AT FAIL - AP FAIL - FD FAIL - YD FAIL - APPR 2 NOT AVAIL
Describe preflight of Nose Landing Gear
Wheels and Tires - Check condition: flat spots, chord showing, pressure etc.
Check Clear of Ice ***
Uplock Hook - UNLOCKED
Downlock Springs - Check Condition
Strut / Wheel Well / Doors - Condition, No Leaks
Ground Locking Pin - Removed
Landing and Taxi Lights - Condition, Clean and Undamaged
Items with *** indicate what?
Items with *** must be accomplished when icing conditions exist or suspected
Describe the preflight of the RAT
Rat Safety Lock Pin - Removed
What is the proper preflight of the Engine Inlet
Check for FOD and leaks inside air inlet.
Ensure there is no damage to T12 sensor and FADEC cooling inlet is clear.
What is the proper preflight action of the Fan Blades?
Check for damaged blades and ensure fan is free to rotate
Check for damage on spinner
How many magnetic level indicators do we have to inspect?
3 on each wing
Describe the Main Landing Gear inspection
Wheels and tires - Condition
Up Lock Hook - unlocked
Down Lock Springs - Condition
Strut / Wheel Wells - Condition and no leaks
Grond Locking Pin - Removed
Break Wear Indicators - Check
What document would you refer to regarding missing static discharges?
Where is it located?
CDL
(Configuration Deviation List)
Located in AFM
What atmospheric conditions require a cold weather preflight inspection?
OAT is 5 degrees or less
Wing fuel temperature 0 degrees C or less
conditions conducive to icing exist
RON and may have frozen contaminants
Residual ice from previous flight
Cold soaked aircraft
What checklist is required prior to completing the deice/anti ice process
The Before Start Checklist
What is the guidance the checklist provides regarding running the APU during deicing procedures?
Should remain off
Where are the Deice / Anti-Ice communications elements found?
They are required
Found in Communication Elements Table
List the required communications elements
Type of fluid used
Percentage of fluid
Time of beginning of final step
Deicing complete
When does the final Hold Over Time begin?
When the final fluid application commences.
What does the HOT represent?
A range of time in which the fluid provides acceptable protection for varying precipation intensities
In the HOT table, what do the longer and shorter times represent?
Heavier vs. Lighter precipitation
What should the crew use to determine a HOT
Official weather observations
Tables from the GDPM should only be used in the absence of intensities listed in the official observation
GDPM Precipitation intensities and types
