Final answer:
In VFR flight in Class D airspace, the aircraft should be equipped with communication equipment and, if specified, a transponder system. The flight crew member must also maintain continuous listening watch on a radio frequency assigned by ATC.
Step-by-step explanation:
In VFR flight in Class D airspace, a person operating an aircraft must ensure several equipment and communication requirements are met. Firstly, the aircraft should be equipped with a radio communication system capable of two-way communication with the appropriate ATC unit. Additionally, if the Class D airspace is specified as Transponder Airspace, the aircraft must have a functioning transponder system that is capable of Mode A/C/S transponder with Mode C encoding. Lastly, a flight crew member should maintain a continuous listening watch on a radio frequency assigned by ATC.
