Instrument Rating Checkride Practice Test

The classification of airspace is essential for understanding how different areas of airspace operate, especially concerning instrument flight rules (IFR) and the requirements for pilots operating within them. The correct classification includes Class A, B, C, D, E, and G.

Class A airspace generally exists from 18,000 feet MSL up to and including FL600. This airspace is primarily for en route traffic and requires pilots to operate under IFR. Class B airspace surrounds major airports and requires both ATC clearance and specific pilot qualifications. Class C airspace, while still requiring communication with ATC, pertains to busy airports but has fewer restrictions than Class B. Class D surrounds smaller airports with a control tower, and Class E airspace is a controlled category that can extend from the surface or between specified altitudes. Lastly, Class G airspace is uncontrolled, allowing for operations without ATC interaction.

The inclusion of Class G is significant because it defines areas where less restrictive airspace rules apply, making it critical for understanding where a pilot may operate under VFR without filing a flight plan or obtaining clearance. The other classifications mentioned in the incorrect options do not align with the official FAA airspace designations, particularly the letters that are not
