What is considered a WET runway?
-Covering 25% of the runway by any visible moisture or water up to 3mm depth (If not Compacted snow, Ice, Wet Ice)
-A damp runway is considered WET
(Can be calculated with the benefit of Thrust Rversers)
What is considered a DRY Runway?
-Free from visible moisture
- Not Contaminated
(Performance is calculated without the benefit of thurstreversers)
What is considered a Contaminated Runway?
Runway is contaminated if more than 25% of its surface is covered:
- A layer of fluid contaminant, deeper than 3mm
- A hard contaminant
(Compacted Snow, Ice (cold and dry), Wet Ice)
Are you allowed to use Flex on contaminated runways?
NO
What rules applies to RWY covered with Wet Ice
No T/O or landing are allowed
What to enter in Flysmart when no Upgrade/Downgrade (T/O)
Enter the the condition. DO NOT enter anything in the RWCC field
What to enter in Flysmart when RWCC is Upgraded (T/O)
Can only be upgraded from RWCC 0 or 1 and to a max of 3.
Use the GRF Takeoff table to find the equivalents from the SNOWTAM
What to enter in Flysmart when RWCC is Downgraded (T/O)
Enter the Runway condition and the Downgraded RWCC.
What are acceptable or contaminants on the aircraft for T/O?
- Thin layer of frost on the underside of the wing tank areas (3mm or less)
- A layer of thin hoard frost on the top of the fuselage
Explain Icing contition
When temperateure is 10 degrees celsius or below and visible moisture is present, or contaminants on the ground that might be ingested to the engines.
Icing condition can be disregarded in Climb and Cruise when SAT is below -40 degrees.
When does Anti skid deactivate?
Below 20kt
How can you see the FDP on a RNP Approach in the Airbus?
The first waypoint in the FMS which have a coded FPA.
What altitudes should you and should you not temperature correct in a RNP Approach?
Correct:
Altitudes between IF down to FDP (Final Descent point).
Also correct FPA in case of no Final App
Not Correct:
FAP/FAF
What colour and Viscosity is Type I De-Icing fluid?
Low Viscosity, orange colour
What colour and Viscosity is Type II De-Icing fluid?
Containts thickening agent, Light Yellor colour
What colour and Viscosity is Type III De-Icing fluid?
Not Used in Braathens, Light Yelow
What colour and Viscosity is Type IV De-Icing fluid?
Same as II but longer holdover time.
Dyed green.
Explain Engine Run ups
When icing condition and 3 degrees or less, engine runup is required before and after flights.
Set parking break and accellerate to 70% N1 for 30s with an interval not more than 30 min.
What shall be reported to the crew after a de-/anti-icing procedure?
- Type of fluid
- Fluid name name of types II or IV
- Concentration of Fluid (mixed with water)
- Local Time of start of the second application of fluid
- The date
- Statement “Post deicing/anti-icing check complete”
