FAR 91.127 — Class E Airport Operations
FAR 91.127 covers operations on or near airports in Class E airspace, including traffic patterns, tower communications, and lost-comm procedures.
FAR 91.127 sets the rules for flying on or near an airport in Class E airspace. Unless ATC or Part 93 says otherwise, you must follow the same operating requirements as Class G airports under § 91.126 — meaning standard left traffic for airplanes (right traffic if indicated), and proper direction of turns for helicopters and gliders.
Key requirements:
- Comply with § 91.126 for traffic patterns and direction of turns.
- Follow any Part 93 traffic patterns specifically established for that airport.
- At airports with an operational control tower, you must establish two-way radio communications with the tower before reaching 4 NM from the airport and up to and including 2,500 feet AGL, and maintain them while operating to, from, through, or on the airport.
If your radio fails in flight under VFR, you may still land if weather is at or above basic VFR minimums, you maintain visual contact with the tower, and you receive a light-gun clearance to land. Under IFR, lost comm requires you to follow § 91.185. This rule matters because Class E surface areas often surround towered fields, and busting the comm requirement is a common checkride and enforcement issue.
