KTX2 Standard

The KTX2 transponder offers the highest possible flight safety because, in addition to the Squawk and flight level, a 24-bit identifier is transmitted which is uniquely assigned to each aircraft. In addition, the air traffic control unit can specifically interrogate certain transponders. The KTX2 thus makes a significant contribution to flight safety.
