What is the altitude range for GFA 3?

The correct answer indicates that the altitude range for GFA 3 is from the surface (SFC) up to 5,000 feet. This range is established in air traffic management to provide specific altitude parameters for aircraft operations, ensuring safe navigation for lower-flying aircraft, including general aviation and light aircraft.

Within this range, air traffic control can monitor and manage traffic more effectively, and pilots are provided with clear guidelines on altitude restrictions. GFA 3 encompasses the lower altitudes where weather phenomena, turbulence, or other factors related to aviation might be prevalent.

The other provided altitude ranges do not align with the defined limits for GFA 3, which specifically covers the surface to 5,000 feet. This ensures that all aircraft operating within this range are adequately informed of potential hazards and airspace regulations related to their altitude.
