The McKinney airspace from the surface up to 2,900 ft MSL is best described as which type of airspace?

• A. Class G airspace
• B. Class E airspace
• C. Class B airspace
• D. Class C airspace

Answer: (B)

This is about how US airspace is classified by where the controlled airspace begins. When airspace from the surface upward remains controlled, it’s Class E. In the McKinney area, the slice from the surface up to 2,900 ft MSL is within controlled airspace, specifically Class E, meaning IFR traffic is protected and ATC separation applies, while VFR pilots operate without a required clearance. This differs from Class G, which would be the uncontrolled airspace if there were no controlled airspace over it; it also isn’t Class B or Class C, which surround the major Dallas-area airports with much tighter ATC services. So the best description for that layer is Class E airspace.
