Study Notes
Airplane Pitch and Control
- Pitching nosedown occurs when power is reduced without control adjustments due to decreased elevator effectiveness from diminished downwash created by the propeller slipstream.
Convective Turbulence Indicators
- Towering cumulus clouds serve as an indicator of potential convective turbulence.
Formation of Cumulonimbus Clouds
- Cumulonimbus clouds require lifting action combined with unstable, moist air for their formation.
Response to Severe Turbulence
- Pilots should aim to maintain a level flight attitude when encountering severe turbulence conditions.
Mountain Wave Turbulence Prediction
- Anticipate possible mountain wave turbulence when winds exceed 40 knots across a mountain ridge in stable air conditions.
Radiation Fog Characteristics
- Radiation fog forms in warm, moist air over low, flatland regions during clear, calm nights.
Steam Fog and Hazards
- Low-level turbulence and hazardous icing conditions often accompany steam fog.
Advection Fog Causes
- Advection fog occurs when an air mass moves inland from the coast during winter months.
Winds and Fog Types
- Advection fog and upslope fog rely on wind presence for their formation and existence.
Hazardous Windshear Locations
- Expect hazardous windshear in areas marked by low-level temperature inversions, within frontal zones, and regions of clear air turbulence.
Thunderstorm Life-Cycle: Dissipating Stage
- The dissipating stage of a thunderstorm is primarily characterized by the predominance of downdrafts.
Turbulent Cloud Types
- Cumulonimbus clouds are associated with the highest levels of turbulence.
