TQ-Avionics

What TQ-Avionics does

TQ-Avionics is a division of privately held German electronics group TQ-Systems GmbH, headquartered in Seefeld, Germany. The division designs and manufactures certified avionics for the general aviation market, with a product portfolio centered on the KRT2 VHF radio transceiver, the KTX2 Mode-S transponder (including the newer KTX2-S.V2), portable radio stations, and a broad accessory ecosystem targeting drop-in replacement of legacy European avionics from Becker, Dittel, Filser, and Funkwerk.

The division's technical value proposition rests on formal certification under EASA, LBA, and EN 9100 regimes, with products holding ETSO/TSO approvals and EASA Form 1 documentation. It has also integrated third-party GPS capability through a technology partnership with Aspen Avionics (NexNav). Customer segments include glider pilots, motor aircraft owners, aerobatic aircraft operators, and maintenance/repair organizations across Germany, the United States, China, Hungary, and Slovenia.

TQ-Avionics operates a hybrid go-to-market combining direct field sales supported by Field Application Engineers with regional dealer and distributor channels. Revenue mechanics are not publicly disclosed; the business is funded and resourced through its parent TQ-Systems, which also operates divisions in E²MS, Embedded, E-Mobility, RoboDrive, Automation, Medical, and Product Compliance. Leadership is held by Detlef Schneider (CEO) and Rüdiger Stahl (Managing Director).

Core offering

TQ-Avionics designs, develops, and manufactures certified avionics products for general aviation aircraft, including ETSO/TSO-certified VHF radio transceivers (KRT2 family), Mode-S transponders with ADS-B Out capability (KTX2 family), and portable radio stations (TB1 RT, TB2 R, TB3 R). The company also supplies a comprehensive accessory ecosystem including adapter plates, mounting frames, cable sets, adapter plugs for legacy avionics systems, GPS sources, and microphones, all produced at its Seefeld, Germany facility.

Product overview

TQ-Avionics is a certified avionics solutions provider for general aviation, offering a unified portfolio of flight radios and transponders manufactured in Germany. The product line centers on the KRT2 flight radio family (KRT2-S, KRT2-F, KRT2-P variants in different form factors) and the KTX2 Mode-S transponder family (KTX2-F, KTX2-S.V2, KTX2-Basic), all featuring ETSO/TSO certification. These core devices are complemented by portable radio stations (TB1 RT, TB2 R, TB3 R) that bundle KRT2 and KTX2 in portable configurations. A comprehensive accessory ecosystem includes adapter plates, mounting frames, cable sets, adapter plugs for legacy radio systems (Becker, Dittel, Filser, Funkwerk), GPS sources for ADS-B Out functionality, and dedicated microphones. The products are characterized by exceptionally low weight, compact design, minimal power consumption, and intuitive operation.

Broad incumbents

• BendixKing (Honeywell): Honeywell-owned legacy GA avionics brand offering radios, transponders and ADF equipment for general aviation; broad incumbent portfolio competing for the same retro-fit and line-fit slots as TQ.
• Garmin: Dominant avionics incumbent with the GNC/GTN/GTR/GX-series radios and GTX Mode-S transponder family serving GA, business and commercial aviation; sets the competitive ceiling and integration standard for VHF radio + transponder cockpit slots.
• Collins Aerospace (RTX): Large diversified aerospace incumbent supplying radios, transponders and integrated avionics suites across business, commercial and military aviation; establishes the high-end integration standard and serves as competitive ceiling for GA expansion strategies.

Direct peers

• Trig Avionics: UK-based maker of VHF radios and Mode-S transponders (TY91/92, TAS-A/TAS600) for general aviation — directly competitive with TQ's KRT2 and KTX2 product lines in the same 57mm form factor segment.
• Aspen Avionics: US GA avionics manufacturer (Evolution PFD/MFD, NexNav GPS sources); already named as TQ's integration partner for GPS, and a comparable GA retrofit/SaaS-style avionics supplier targeting the same owner-flown segment.
• Funkwerk Avionics: German producer of ATR radio transceivers and Mode-S transponders (ATR500/600, FSG40/50/60) for gliders and motor aircraft — directly comparable product families that TQ specifically targets with adapter replacements.
• Filser (formerly Dittel/Filser avionics): German glider-avionics specialist with ATR and FSG-series radios directly named in TQ's adapter compatibility list, indicating overlapping customer base in the European glider community.
• Dynon Avionics: Specialist in experimental and certified GA avionics (SkyView, SV-COM, SV-XPNDR); comparable platform play in the light aircraft and glider cockpit retrofit market that TQ targets.
• Becker Avionik: German avionics manufacturer producing VHF transceivers (AR6201, RT3201) for general and military aviation; TQ explicitly markets adapter plugs for replacement of Becker radios, indicating head-to-head retrofit competition.

Emerging players

• FreeFlight Systems: US-based avionics manufacturer specializing in ADS-B Out transponders and GPS sensors for GA and business aviation — overlapping with TQ's KTX2/S and TQ ADS-B Out kit portfolio at the ADS-B mandate replacement frontier.
