Part 91.215 (Transponder and Altitude Reporting Equipment)

Part 91.215 is a regulation that requires aircraft operating under visual flight rules (VFR) in certain airspace to have functioning transponders with altitude-reporting capabilities. Specifically, in controlled airspace like around airports or high-altitude regions, the aircraft must broadcast its identification and altitude to air traffic control. This helps controllers track the aircraft’s position and altitude in real-time, ensuring safe separation from other aircraft and improving overall airspace safety. The regulation specifies the equipment standards and operational requirements necessary for compliance.
