Study Notes
Wind Shear
- A change in direction and/or wind speed over a short distance
- Microbursts are dangerous sources of wind shear
- Microbursts are downdrafts associated with connective activity
- Recovery from wind shear includes using full power and climbing just above the stall speed
Icing
- FARs state that pilots cannot fly into known icing without anti-icing/deicing equipment
