FAA Ground School Practice Test

Unless otherwise specified, Federal Airways include Class E airspace extending upward from what altitude?

1. 1000 FT above the surface

2. 1200 FT above the surface

3. 1500 FT above the surface

4. 2000 FT above the surface

The correct answer is: 1200 FT above the surface

Federal Airways, which are also known as Jet Routes in the United States, typically operate within Class E airspace that begins at an altitude of 1,200 feet above the surface unless specified otherwise. This altitude is significant because it provides a structure for the flow of traffic at a safe altitude while still allowing for operations in the lower airspace for different types of aircraft, including general aviation. The designation of 1,200 feet as the floor for federal airways allows for consistent management of air traffic and effective separation of aircraft, particularly in terminal areas and while transitioning through different airspace classifications. Understanding this standard altitude for Class E airspace is crucial for pilots to ensure compliance with air traffic control regulations and maintain safety throughout their flight operations.
