Knowledge Validation Flashcards
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

CDL
(Configuration Deviation List)
Located in AFM

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
When is a pre-takeoff contamination check required
After the HOT has been exceeded or the HOT is no longer valid due to changing weather conditions.
Operating in Heavy Snow to ensure wings, control surfacess and critical surfaces are free of contaminants.
Can the pre takeoff contamination check be performed if the deice process was initiated at a location other than the wings?
NO
Engine failure procedure says hold STD
What do you do at fix?
Hold on inbound course
Standard Turns
Right Turns
What is the landing performance heirarcy
RW RCC values when reported
Contaminant type and BA
Most restrictive RCC is used for landing assessment
Are RCCs bidirectional
YES
They are evaluated to include displaced thresholds and are measured equally in either direction
What does TALPA stand for?
Takeoff and Landing Perforformance Assessment
What is the RCAM
Runway Condition Assessment Matrix
It is the tool used to access and report surface conditions
Maps FICON (field condition) contamination type and depth to a RCC
RCCs are used for?
For landing distance calculations
Used for departures to identify the runway third with most limiting contaminant
Used to determine operating limitations such as crosswind limits with low runway friction
RCC of 0 represents what?
NIL
Runway immediately closed
Limitations of RCC of 1 and 2
An Alternate must be listed
Not required with multiple runways with one runway reporting 3 or higher for every 3rd.
Dispatch requires expected runway to have reported an RCC of 3 or higher
How long are RCC Notams for?
RSC Notams are valid for 8 hours
What percentage of the runway surface needs to be covered to be considered contaminated?
Greater than 25%
What are RCCs used for?
For determining landing performance.
Used for departures to identify the runway third with the most limiting contaminant.
Used to determine operating crosswind limitations
What does TALPA stand for?
Takeoff and Landing Performance Assessment
What is RCAM
Runway Condition Assessment Matrix
Used to assess and report surface conditions when contaminants are present via FICON
Maps contamination type and depth to a RCC
What does RCC represent?
The braking action expected for a particular contaminant level
When powering up the aircraft, what is the minimum voltage?
22.5 volts
21V -22V consult SOP Safety and Power up table.
