Basic VFR Weather Minimums Flashcards

Study Notes

Class A Airspace

Flight visibility is not specified for Class A airspace.
Distance from clouds is not applicable.

Class B Airspace

Requires a flight visibility of 3 statute miles.
Distance from clouds must be clear of clouds.

Class C Airspace

Flight visibility is 3 statute miles.
Requires 512 bah (500 feet below, 1,000 feet above, 2,000 feet horizontal) for distance from clouds.

Class D Airspace

Flight visibility also set at 3 statute miles.
Adheres to 512 bah distance from clouds.

Class E Airspace

Less than 10,000 feet MSL: flight visibility requirement is 3 statute miles.
At or above 10,000 feet MSL: flight visibility increases to 5 statute miles.
Distance from clouds below 10,000 feet MSL follows 512 bah; above, it follows 111 bah.

Class G Airspace

Visibility requirements vary based on conditions:
- Daytime, 1,200 feet or less AGL: 1 statute mile visibility.
- Nighttime, 1,200 feet or less AGL: 3 statute miles visibility.
- Daytime, more than 1,200 feet AGL but less than 10,000 feet MSL: 1 statute mile visibility.
- Nighttime, above 1,200 feet AGL but below 10,000 feet MSL: 3 statute miles visibility.
- Above 10,000 feet MSL: 5 statute miles visibility.
Distance requirements include:
- Daytime, 1,200 feet or less AGL: clear of clouds.
- Nighttime, 1,200 feet or less AGL: 512 bah.
- Other conditions (both day and night) above 1,200 feet follow 512 bah or 111 bah guidelines accordingly.

Special VFR Weather Minimums

Operations must be ATC cleared, clear of clouds, and have at least 1 statute mile visibility.
Only permitted between sunrise and sunset unless specific IFR conditions are met.

Ground and Flight Visibility

Under special VFR, aircraft cannot take off or land unless:
- Ground visibility is at least 1 statute mile.
- If visibility isn't reported, flight visibility must meet the 1 statute mile requirement.

IFR and VFR Conditions

Low IFR: Ceiling less than 500 feet and/or visibility less than 1 statute mile.
IFR: Ceiling between 500 to less than 1,000 feet and/or visibility between 1 to less than 3 statute miles.
Marginal VFR: Ceiling between 1,000 to 3,000 feet and/or visibility between 3 to 5 statute miles.
VFR: Ceiling greater than 3,000 feet and visibility greater than 5 statute miles, including clear sky conditions.
