Study Notes
Thunderstorms
- Thunderstorms are a significant weather challenge for aviation, requiring critical knowledge for safe navigation.
- Three essential components for thunderstorm development: moisture, a lifting force, and atmospheric instability.
- Moisture is a critical ingredient, and a lifting force (e.g., cold front, warm air at the surface, or mountain range) is required to elevate this moisture.
- Atmospheric instability sets the stage for a thunderstorm, where warm air rests below cooler air.
Thunderstorm Stages
- Cumulus stage: vigorous updrafts construct cloud towers.
- Mature stage: precipitation begins to form, along with lightning and thunder, indicating intense energy release.
- Dissipating stage: updrafts weaken, and downdrafts prevail, leading to the storm's eventual decay.
Dangers of Thunderstorms
- Severe turbulence, hail, lightning, wind shear, and microbursts pose significant threats to aircraft.
- Microbursts are intense downdrafts that can result in drastic performance drops for aircraft during takeoff or landing.
Safety Measures
- Thorough pre-flight weather briefings to avoid flying into a brewing storm.
- Real-time, in-flight weather updates to navigate away from unforeseen developments.
- Maintain a safe distance (at least 20 nautical miles) from severe storms, take guidance from air traffic control, and be prepared to alter course decisively.
Wind Shear
- Wind shear refers to a rapid change in wind speed or direction over a short distance, posing critical consequences for aircraft during takeoff and landing.
- Causes of wind shear: weather fronts, thunderstorms, or topography.
- Microbursts are an intense form of wind shear that can occur during thunderstorms, posing severe risks for aircraft.
Wind Shear Safety Measures
- Thorough pre-flight weather briefings to identify potential wind shear conditions.
- Onboard detection systems and technologies, such as the Low-Level Wind Shear Alert System (LLWAS).
- Training and preparedness for wind shear situations are essential in a pilot's skill set.
Pilot Response to Wind Shear
- Techniques to maintain control over the aircraft's performance during wind shear conditions, such as powering up and adopting a nose-down attitude in a headwind shift.
Precipitation and Flight Safety
- Rain: light to moderate rain typically poses minimal risk, but heavy rain can reduce visibility and alter runway friction.
- Snow: snowfall can decrease visibility and affect aircraft performance due to accumulation on wings and surfaces.
- Sleet: sleet can accumulate on aircraft surfaces, leading to additional weight and potential control issues, and create slippery conditions on runways and taxiways.
- Freezing Rain: freezing rain is hazardous for aviation, as it can disrupt aerodynamic flow, increase weight, and lead to a loss of lift.
- Hail: hail can be extremely dangerous for aircraft, especially during thunderstorms.
