What must a pilot do to enter Class B airspace with an inoperative transponder?

To enter Class B airspace with an inoperative transponder, the pilot is required to submit a request for a deviation from the controlling ATC facility. Class B airspace is designated with specific operational procedures and safety requirements, one of which is the functioning of a transponder. This equipment allows air traffic control to monitor and manage air traffic within this busy airspace efficiently.

When a pilot encounters a situation where the transponder is not operational, they must inform air traffic control and seek permission to operate in the Class B airspace without the necessary equipment. ATC may grant permission based on the circumstances, allowing the pilot to proceed safely. This protocol is designed to maintain safety and prevent any potential conflicts in an area where air traffic density is typically high.

Alternative options, such as installing a new transponder before flight, completing a safety inspection, or notifying passengers, do not fulfill the requirement for safely operating in Class B airspace. While maintaining aircraft safety and equipment functionality is essential, the primary regulatory requirement in this scenario is directly communicating with ATC to seek a deviation.
