Near an airport with instrument approaches, Class E airspace commonly begins at what altitude?

Choices

  • ✓ 700 feet AGLcorrect

    A 700-foot AGL floor is common near airports with instrument approaches (shown by the magenta shading).

  • 18,000 feet MSL

    That is the base of Class A, not a typical Class E floor.

  • The surface everywhere

    Surface Class E exists in some places but is not the common floor near these airports.

  • 10,000 feet MSL

    10,000 MSL is a speed/transponder threshold, not the Class E floor.

Why

Class E commonly begins at 1,200 feet AGL, or 700 feet AGL near airports with instrument approaches, and at the surface in some locations.
