Study Notes

Class E Airspace Overview

Class E airspace, also known as "Echo," is controlled airspace not classified as A, B, C, or D, prevalent in the 48 contiguous states and Alaska.
Identified primarily as the airspace "everywhere else."

Identification on Sectional Charts

Floors of Class E airspace indicated by specific visual cues:
- 1,200 FT AGL: Blue vignette
- 700 FT AGL: Magenta vignette
- Surface: Dashed magenta line

Breakdown of Class E Airspace

Class E airspace is categorized into distinct sections represented by the acronym "SET FOOD":
- S: Surface airport areas
- E: Extensions
- T: Transition airspace
- F: Federal airways
- O: Off-shore airspace
- O: Other (below & above A)
- D: Domestic enroute areas

Specific Class E Sections

Surface Airport Areas: These are indicated by a dashed magenta area to protect instrument approach procedures.
Extensions: Rectangular dashed magenta areas that facilitate approach procedures for Class B, C, or D airports.
Transition Airspace: Areas facilitating traffic movement between terminal areas and enroute environments; identified by:
- 700 FT AGL: Magenta vignette
- 1,200 FT AGL: Blue vignette
Federal Airways: "Highways in the sky," 8 NM wide, spanning from 1,200 FT AGL to 18,000 FT MSL, depicted by blue lines on charts.
Off-shore Airspace: Designated to manage IFR separation beyond 12 NM from the coast, shown with "zipper" borders starting at 1,300 FT MSL.
Other Airspace Areas: Extends from 14,500 FT to 18,000 FT MSL, with Class E continuing above Class A airspace up to FL 600 and beyond.
Domestic Enroute Areas: Positioned outside or between federal airways to assist with air traffic control separation.

Flight Requirements and VFR Minimums

Class E Airspace Flight Requirements: No specific requirements to operate within.
VFR Minimums at or above 10,000 FT: Visibility must be at least 5 miles.
VFR Minimums below 10,000 FT: Visibility must be at least 3 miles.
