Certified Flight Instructor (CFI) Practice Exam

Prior to entering Class D airspace, what must each aircraft establish?

1. VFR communication plans

2. Two-way radio communications with ATC

3. A flight plan

4. Visual line of sight

The correct answer is: Two-way radio communications with ATC

Before entering Class D airspace, aircraft are required to establish two-way radio communications with Air Traffic Control (ATC). Class D airspace is defined by its controlled nature, where ATC provides services to manage the flow of traffic and ensure safety. In order to enter and operate within this airspace safely, it is essential for pilots to communicate with ATC to receive necessary instructions and clearances. This requirement ensures that pilots are aware of other aircraft in the vicinity and that ATC can provide guidance regarding the current traffic conditions, weather, and any other pertinent flight information. Establishing this communication is crucial for maintaining safety, as it helps prevent conflicts with other aircraft operating in the controlled airspace.
