Runway Condition Report (RCR)
Runway split into thirds with each described using:
- Runway Conditions Code (RWYCC)
- Contaminant Type
- Contaminate Coverage (%)
- Contaminant Depth
NOTE: Runway thirds reflect physical extent of the RW rather than reflecting position and length of declared distances within this extent
- Runway with significant displaced threshold
- Intersection T/O
- When part of a runway is declared as a runway safety area but its available for take-off in the opposite direction
Promulgated through:
- SNOWTAM
- ATIS
- ATC
What is a DRY Runway
A runway whose surface is free of visible moisture and not contaminated within the area intended to be used
What is a WET Runway
A runway whose surface is covered by any visible dampness or water up to and including 3mm deep within the area intended to be used
What is a CONTAMINATED Runway
A runway of which a significant portion of its surface area (whether in isolated areas or not) within the length and width being used is covered by one or more of:
- More than 3mm of water, wet snow, dry snow, slush
- Compacted snow, or
- Ice
What is Degraded Braking action?
A runway covered by compacted snow or ice or a runway that is reported to be slippery when wet.
A reported braking action is usually given for such runways
What is a slippery runway?
A runway having a theoretical aircraft braking coefficient of 0.05 mu
Runway Condition Assessment Matric (RCAM) used in conjunction with RCR to establish Runway Braking Action
Details for each condition code:
- Assessment criteria of the RCR code
- Downgrade assessment criteria
- Associated crosswind limitation (Embraer RCAM)
TORA, ASDA, TODA
Takeoff Distance Required (TODR)
The greater of:
All Engines operating
- 115% of horizontal distance travelled to reach a screen height of 35ft
One Engine Inoperative (Wet/Dry)
- Horizontal distance from Brake Release Point (BRP) to the point aircraft attains 35ft (15ft Wet) assuming critical engine fails at Vef
Jet engine do not have a critical engine EXCEPT - The upwind one. If you lose the in to wind engine, the aircraft will yaw more (on the ground)
E190 has 4 different flap settings for T/O
Flap 1
Flap 2
Flap 3
Flap 4
With ATTCS T/O 2 give T/O 1 RSV when ATTCS activated
T/O 3 gives you T/O 3 RSV - which isn’t T/O 1 RSV
The N1 target calculated by the FADEC should be within:
-0.1% to +0.5% of calculated N1 target
