FAA Part 107 Drone Practice Test 2025 – 400 Free Practice Questions to Pass the Exam

When flying in Class G airspace, ATC authorization is generally not required. Class G airspace is uncontrolled airspace, meaning that air traffic control does not have the regulatory authority to manage operations within it as they do in controlled airspace. This allows pilots, including those operating drones, more freedom when flying in these areas without needing specific clearance from ATC.

In the scenario where the entire flight to inspect railroad tracks occurs within Class G airspace, it's important to remember that the pilot is responsible for ensuring they are operating safely and in compliance with any applicable regulations. Therefore, since there is no obligation to obtain ATC authorization in this type of airspace, the correct understanding is that the pilot can conduct their inspection without needing any additional approval from air traffic control.

While it might seem that certain situations, like proximity to Class D airspace or specific altitudes, could require ATC interaction, they do not apply here when remaining fully within Class G airspace. Thus, operating within this airspace simplifies the process for unmanned aircraft operators.
