Wet-runway braking friction
Braking friction vs speed (TC AIM AIR 1.6.6):
| Surface | Friction vs speed |
|---|---|
| Wet runway | Falls as speed increases; improves as aircraft slows |
| Packed snow or ice (fixed temperature) | About constant |
- Separate from hydroplaning.
- Cause: water not fully squeezed from tyre contact patch.
Trap: assuming wet-runway friction holds steady with speed like packed snow or ice.
