Basic VFR Weather Minimums

Has no visibility minimums or cloud distance requirements. This is because in class Alpha airspace you are required to fly IFR with...
- IFR flight plan
- Instrument rating
- Clearance and 2 way communication with ATC
- ADS-B out, RNAV, and a Mode C transponder

- covers a wide area
- forms in stable atmospheric conditions

- clouds with rain

- wispy
- seen at high altitudes
- seen in unstable air
- usually associated with icing

- unstable air
- high moisture content
- lots of lifting action

- occurs every 15 mins
- can bump you down 6000ft per min
- sudden downward motion

Forms in moist stable air that is pushed up into a terrain by the wind

- cold air that moves over warm air
- cools moist air to the dewpoint level (adiabatic level)
- has low level TB
- low icing

Fog produced from moisture developed by rain

- coastel fog that forms when a mass of warm air travels over a mass of cold air
- chilled land cools the warm air creating the fog

- occurs when heat radiates from the ground thus causing the loss of heat.
- warm moist air tends to travel over low flat areas on cool nights
