• The Trig TT21 is a two part transponder system,
  which includes an integrated altitude encoder. In
  design and technology it is equivalent to the
  TT22, however, the transmitted output power of
  the TT21 is lower, qualifying the unit as a Class
  2 transponder.

• Class 2 transponders are suitable for aircraft
  cruising slower than 175 knots, and operating
  below 15,000 feet, VFR or IFR.

  15K or faster than 175 knots, you need the more
