FAA Military Competency Practice Exam

In Class E airspace near an airport with an operating control tower, when must a pilot establish communication?

1. 3 NM prior to arrival

2. 4 NM, and up to and including 2,500 feet AGL

3. Only during the final approach phase

4. As soon as the aircraft is airborne

The correct answer is: 4 NM, and up to and including 2,500 feet AGL

When operating in Class E airspace near an airport with an active control tower, establishing communication with the tower is essential for maintaining safety and orderly traffic flow. The requirement to establish communication up to 4 nautical miles (NM) from the airport and including up to and at 2,500 feet above ground level (AGL) is particularly important because it allows pilots to receive essential traffic information, weather updates, and any pertinent instructions for landing procedures. This communication requirement is designed to ensure that pilots are sufficiently informed and prepared before entering the busy airspace around airports. It also helps air traffic controllers manage air traffic effectively, especially as aircraft are arriving or departing, thus minimizing the risk of collisions or miscommunication. Engaging with the control tower within this specified range helps facilitate smoother operations and safer flight practices. Other potential answers might not cover the necessary safety protocols effectively. For instance, establishing communication only after becoming airborne or just during the final approach phase may not provide adequate time for coordination or to receive important instructions applicable during the transition into the airport's airspace. Similarly, a distance of 3 NM would not follow the established requirement of 4 NM as a standard minimum, potentially putting the aircraft in a situation lacking proper communication before entering a congested
