TL electronic has traditionally worked in the field of defence the company’s first significant contract was for defence. We continue to work in partnership with significant organizations on design and development of military systems in the context of aviation and UAV.


TL elektronic produces a select line of General Aviation certified onboard systems. Manufactured for the exclusive use of aircraft manufacturers and commercial aircraft, TL-elektronic has both designed and developed instruments as standard equipment aboard certified aircraft as well as certified versions if its own extensive range of LSA avionics.

Light Sport Aircraft & Experimental
With 15 years experience in the LSA market TL elektronic has become one of the most recognised names in the field of Light Sport and Experimental aviation. This non-certified category of avionics provides the user with an exciting, innovative, cutting edge range of products giving pilots a barrier free line of avionics that have all the capabilities and reliability of certified instruments at a fraction of the price.

TL elektronic has been significantly involved in the design and production of avionics for Unmanned Aerial Vehicles and Unmanned Airborne Systems with defence, security and humanitarian applications providing C2I (Command Control and Intelligence) integral Flight and Engine Monitoring Systems as well as Autonomously Guided Precision Airdrop Delivery platforms.

TL electronic continues to strive forward, ambitiously reaching now for the stars as it engages into research into the design and manufacture of terrestrial, aerospace, and extra-atmospheric software and hardware systems.
