Study Notes
Vertical Extent of Class E Airspace
- Extends from 14,500' MSL or 1,500' AGL (whichever is higher) up to but not including 18,000' MSL, and above FL 600.
Lateral Extent of Class E Airspace
- Covers the entire continental U.S. with a small exception in Alaska; extends 12 nautical miles offshore.
Entry Requirements for Class E Airspace
- No specific requirements for VFR pilots; IFR pilots must obtain ATC clearance.
Communications Requirements in Class E Airspace
- VFR pilots are not required to communicate; IFR pilots must maintain two-way radio communication with ATC.
Equipment Requirements in Class E Airspace
- Mode C transponder is required at and above 10,000' MSL; otherwise, there are no special equipment requirements.
Pilot Certification Requirements in Class E Airspace
- Student pilots are permitted to operate in Class E airspace.
Traffic Separation Provided by ATC in Class E Airspace
- ATC provides separation for IFR traffic only (IFR/IFR).
Speed Limit in Class E Airspace
- Maximum speed is 250 knots below 10,000' MSL; speed is unrestricted above this altitude.
Class E Depiction on VFR Sectional Chart
- Various depictions:
- Surface: indicated by a dashed magenta line.
- 700' AGL: depicted as a magenta vignette.
- 1,200' AGL: shown as a blue vignette.
Basic VFR Weather Minimums, Class E Below 10,000' MSL
- Visibility requirement: 3 statute miles.
- Cloud clearance: 500' below, 1,000' above, and 2,000' horizontally.
Basic VFR Weather Minimums, Class E At or Above 10,000' MSL
- Visibility requirement: 5 statute miles.
- Cloud clearance: 1,000' below, 1,000' above, and 1 statute mile horizontally.
Types of Class E Airspace Areas
- Surface area for an airport.
- Extensions to Class B, C, or D surface areas.
- Transition areas.
- Federal airways.
- En route domestic areas.
- Offshore airspace areas.
Floor Altitude of Class E Airspace Designated for Federal Airways
- Set at 1,200' AGL.
Floor Altitudes of Class E Airspace Designated for Transition Areas
- Can be 700' AGL or 1,200' AGL.
Class E Airspace: Controlled vs. Uncontrolled
- Although VFR pilots can operate without talking to ATC, Class E is considered controlled airspace due to IFR operations needing ATC clearance and communication.
