Operating an aircraft in Class B airspace requires a 4096 code transponder with altitude reporting capabilities. Class B airspace is the most restrictive type of controlled airspace and typically surrounds major airports. To ensure safe separation and situational awareness among the high volume of air traffic in these areas, the FAA mandates that all aircraft operating within Class B airspace be equipped with a transponder that not only transmits a unique 4096 code but also has the ability to report the aircraft's altitude. This altitude reporting feature provides air traffic control with essential information to manage traffic effectively and maintain safe distances between aircraft.

In contrast, while a VOR receiver, a basic 4096 code transponder without altitude reporting, and a GPS system are useful instruments for navigation and situational awareness, they do not fulfill the specific regulatory requirement for operating in Class B airspace. Only the combination of a 4096 code transponder with altitude reporting meets the necessary criteria for ensuring the safety and efficiency of operations in such a busy airspace.
