| Assessment criteria | Downgrade assessment criteria | ||
| Runway Condition Code (RWYCC) | Runway surface description | Aeroplane deceleration or directional control observation | Pilot report of runway braking action |
| 6 | · DRY | --- | --- |
| 5 | · WET (The runway surface is covered by any visible dampness or water up to and including 3 mm depth | Braking deceleration is normal for wheel braking effort applied AND directional control is normal | GOOD |
| 4 |
| Braking deceleration OR directional control is between Good and medium | GOOD TO MEDIUM |
| 3 | · WET (slippery wet runway) | Braking deceleration is noticeably reduced for the wheel braking effort applied OR directional control is noticeably reduced | MEDIUM |
| 2 | More than 3 mm depth of water: · STANDING WATER | Braking deceleration OR directional control is between Medium and Poor | MEDIUM TO POOR |
| 1 |
| Braking deceleration is significantly reduced for the wheel braking effort applied OR directional control is significantly reduced | POOR |
| 0 |
| Braking deceleration is minimal to non-existent for the wheel braking effort applied OR directional control is uncertain | LESS THAN POOR |
