The TT21 and TT22 transponders are the smaller and lighter among the S mode transponders.

Approved by the EASA and the FAA, they integrate an alticoder for a simplified installation and more space. The TT21 offers an output power of 130W, whereas the TT22 can rise until 250W and is adapted to high altitude and high performances flights. They are pleasant, with a luminous and waterproof display, and are compatible with ADS-B for an ameliorated air surveillance and more effective trajectories.
