a) establish two way radio communication, obtain clearance to enter, mode C transponder
b) establish two way radio communication, mode C transponder only if designated
c) establish two way radio communication, obtain clearance to enter, mode C transponder only designated d) none of the above

Answer 1

To enter Class D airspace under VFR, you must establish two-way radio communication with ATC; a Mode C transponder is required in certain conditions.

Step-by-step explanation:

To enter a Class D airspace under Visual Flight Rules (VFR), you must establish two-way radio communication with the air traffic control (ATC) facility responsible for that airspace. You only need to have an operable Mode C transponder if you are flying at or above 2,500 feet above the surface and within 4 nautical miles of the primary airport in the Class D airspace or in designated areas. Clearance to enter is not a requirement for Class D airspace; rather, two-way radio communication ensures you are recognized by ATC and they know your intentions.
