Certified quality products for aviation

TQ is one of the leading solution providers for innovative and future-oriented technologies.

In 2016 TQ took over the avionic department of the company Dittel. The merger of decades of avionics and electronics experience is the basis for the highest quality of TQ avionics products.

After receiving the ADOA and POA approvals from LBA and EASA in 2017, we have been producing our KRT2 state-of-the-art radios and KTX2 transponders since the beginning of 2018, and are themselves issuing the EASA Form1.
