Answer:
The minimum requirements for airplane operations under Special VFR (SVFR) in Class D airspace at night are as follows:
1. The airplane must be under radar surveillance at all times while in Class D airspace: This means that air traffic control (ATC) must have radar coverage and be able to provide continuous radar monitoring of the aircraft's position.
2. The airplane must be equipped for IFR with an altitude reporting transponder: The aircraft must have the necessary instruments and equipment required for Instrument Flight Rules (IFR) operations. Additionally, it must be equipped with an altitude reporting transponder, which enables ATC to receive altitude information from the aircraft.
3. The pilot must be instrument rated: The pilot operating the aircraft must hold an Instrument Rating, which signifies that they have the necessary knowledge, skills, and experience to operate an aircraft under IFR conditions.
4. The airplane must be IFR equipped: The aircraft itself must have the required instruments and equipment to operate under IFR conditions. This includes navigation equipment, communication systems, and other necessary instruments to comply with IFR regulations.
It's important to note that these requirements are specific to operating under SVFR in Class D airspace at night. Other airspace classes and operational scenarios may have different requirements. Pilots should always consult the applicable regulations and consult with ATC for specific requirements and procedures before conducting SVFR operations.
