Study Notes
Airspace Systems Overview
- The airspace designations standardize classifications in the U.S. to align with international standards.
- Uncontrolled airspace is classified as Class G.
Class G Airspace
- Class G extends from the surface to either 1,200 ft or 700 ft AGL.
- VFR pilots in Class G have reduced cloud and visibility restrictions due to minimal IFR traffic.
Class E Airspace
- Class E starts from either 700 ft or 1,200 ft AGL, not including 18,000 ft MSL.
- The floor of Class E is identified by a fuzzy magenta line on charts.
Class D Airspace
- Represented by a blue segmented circle on sectional charts.
- Lateral dimensions depend on the instrument procedures established for that airspace.
- Only classified as Class D when the control tower operates.
Communication Requirements
- Two-way radio communication with ATC is necessary for takeoffs and landings at towered airports, regardless of weather.
- Must establish communication with the controlling ATC facility before entering Class C airspace.
- Minimum required radio equipment for Class C includes: two-way radio, 4096-code transponder, and an encoding altimeter.
Airspace Operations
- Operations within Class C airspace must be conducted in aircraft with a Mode C transponder.
- For satellite airports within Class C, pilots must contact ATC after takeoff.
- Pilots must contact approach control before entering Class C airspace.
Federal Airspace and Restricted Areas
- Federal Airways are Class E airspace extending from 1,200 ft AGL to 17,999 ft.
- Hazards in restricted areas include invisible aerial gunnery or guided missiles, requiring prior authorization for entry.
Military Operations Areas (MOA)
- Areas like Devils Lake East MOA may have military training activities necessitating cautious flying.
- Pilots can expect IFR training flights above 1,500 AGL at high speeds on routes like IR 644.
Temporary Flight Restrictions (TFR)
- TFRs may be issued to protect public figures among other reasons.
Wildlife Refuge Guidelines
- Pilots should fly no lower than 2,000 ft AGL over national wildlife refuges.
Flight Visibility and Cloud Clearance
- Minimum flight visibility for VFR operations over 10,000 ft MSL is 5 miles.
- Horizontal distance from clouds required for VFR above 10,000 ft is 1 mile; 1,000 ft above clouds clearance required.
- In Class G airspace at 700 ft AGL, at least 1 mile visibility is required during daylight.
Controlled Airspace Requirements
- In controlled airspace below 10,000 ft, visibility must be at least 3 miles during VFR.
- Basic VFR conditions for Class D airspace are a ceiling of 1,000 ft and visibility of 3 miles.
- A rotating beacon operational during daylight hours indicates below basic VFR weather conditions at airports in Class G airspace.
