Study Notes

VFR Weather Minimums

Class B Airspace: Requires 3 miles visibility and clear of clouds.
Classes C, D, and E (Below 10,000 MSL): 3 miles visibility with cloud clearance of 500 feet below, 1,000 feet above, and 2,000 feet horizontally.
Class E Above 10,000 MSL: 5 miles visibility with cloud clearance of 1,000 feet below, 1,000 feet above, and 1 mile horizontally.
Class C Airspace: Same requirements as Classes C, D, and E below 10,000 MSL (3 miles visibility, cloud clearance).
Class D Airspace: Identical visibility and cloud clearance requirement as Classes C and E below 10,000 MSL.
Class G Airspace (1,200 AGL or Less/Daytime): Requires 1 mile visibility and clear of clouds.
Class G Airspace (1,200 AGL or Less/Nighttime): 3 miles visibility with standard cloud clearance.
Class G Airspace (Greater than 1,200 AGL but Below 10,000 MSL/Daytime): 1 mile visibility and standard cloud clearance required.
Class G Airspace (Greater than 1,200 AGL but Below 10,000 MSL/Nighttime): 3 miles visibility with standard cloud clearance.
Class G Airspace (Above 10,000 MSL): Requires 5 miles visibility with cloud clearance of 1,000 feet below, 1,000 feet above, and 1 mile horizontally.

Flight Rules and Conditions

VFR (Visual Flight Rules): Requires ceilings greater than 3,000 feet and visibility of at least 5 miles.
MVFR (Marginal Visual Flight Rules): Ceilings between 1,000-3,000 feet and visibility between 3-5 miles.
IFR (Instrument Flight Rules): Ceilings between 500-1,000 feet and visibility of 1-3 miles.
LIFR (Low Instrument Flight Rules): Ceilings below 500 feet and visibility less than 1 mile.

Weather Phenomena

Cold Front Weather: Characterized by cumulus and cumulonimbus clouds, squall lines, thunderstorms, frontal turbulence, and rapid weather changes. Moves generally from northwest to southeast with significant pressure changes and visibility patterns.
Warm Front Weather: Associated with widespread rainfall, fog, low ceilings, and heavy snow in winter as warm air rises over cold air, leading to widespread low visibility conditions.

Thunderstorm Development

Stages of Thunderstorms:
- Cumulus Stage: Formation of growing clouds.
- Mature Stage: Thunderstorm fully developed with precipitation.
- Dissipating Stage: Loss of energy and weakening of the storm.

Accident Definitions and Criteria

NTSB Accident Definition: Involves any operation-related occurrence leading to serious injury or substantial damage, occurring from boarding to disembarkation.
Serious Injury Criteria: Hospitalization exceeding 48 hours, or includes specific severe injuries like fractures (excluding minor toe, finger, or nose injuries) and severe burns.
Substantial Damage Definition: Damage that affects the aircraft’s structural strength, performance, or flight characteristics, requiring major repair or part replacement.

Incident Definition

NTSB Incident Definition: Includes property damage over $25,000, in-flight fires, flight control system malfunctions, total loss of electronic cockpit information, and compliance with resolution advisories in IFR.
