What Avionik Straubing does

Avionik Straubing is a German EASA-certified avionics services and product development company founded in 1977 at Straubing-Wallmühle airfield. It operates three integrated business lines: design and certification of proprietary avionics hardware (the APS4A altitude preselect system, MFI02 multifunction indicator, LPV Converter with EASA/FAA STC, FQIS fuel quantity systems, HCU200 heater control unit, and Datenlogger/CAWSDU data logger), maintenance and repair services spanning COM/NAV, autopilot, FMS, GPS, radar, and David Clark headsets across OEM platforms (Garmin, Honeywell, S-TEC, Collins, Bendix/King), and panel modernization from analog upgrades to glass cockpit installations (Garmin G500/G600, Aspen). The company is an EASA Part 21J Design Organization with hundreds of issued STCs, a Part 145 maintenance organization, FAA and CAA UK certified, and operates an in-house environmental testing laboratory per RTCA DO-160 and MIL-standards.

The firm generates revenue through four channels: hourly maintenance and repair services, quoted installation and panel modernization projects, development and certification fees (STC/ETSO licensing), and new and used equipment sales via avionik.de shop (3,300+ used device database). Pricing is uniformly quote-based with no public price disclosure. Customer segments are General Aviation (private owners, single/twin-engine, gliders, ultralights) and Business Aviation as primary verticals, with secondary exposure to Commercial Aviation and Defense. Geographic reach centers on Central Europe with expansion into the UK (post-2025 CAA approval) and Middle East. The company maintains authorized dealer and installation relationships with roughly 25 OEMs.

In 2026, ownership transferred from founding couple Gunter and Iris Hemmel to long-term executives Josef Breu, Martin Scheifl, and Stefan Schönsteiner via a Management Buyout. The legal structure comprises two GmbH entities: Vertriebs- und Service GmbH (sales and service) and Entwicklungs GmbH (development), both registered in Straubing. The company is privately held with no external investors, no parent company, and no disclosed funding rounds.

Direct peers

• Aspen Avionics: Aspen produces glass cockpit Evolution displays for retrofit GA aircraft and is a Core-tier partner of Avionik Straubing. The two compete and collaborate in the same panel-modernization workflow for single and twin-engine aircraft owners.
• Avidyne Corporation: Avidyne designs and manufactures avionics for General Aviation (IFD-series navigators, displays) and is a Core-tier partner of Avionik Straubing. Both serve the same GA/Business Aviation customers with integrated cockpit and navigation solutions, with similar DO-178/DO-254-driven development pipelines.
• Trig Avionics: Trig Avionics produces transponders, radios and ADS-B solutions for GA and is a Minor partner of Avionik Straubing. Both supply and install certified retrofit avionics products across the European GA fleet.
• Mid-Continent Instruments and Avionics: Mid-Continent manufactures standby instruments, attitude indicators and avionics for GA and Business Aviation. It is a Minor partner of Avionik Straubing and pursues an analogous strategy of certified niche products plus MRO support.
• Genesys Aerosystems (S-TEC): Genesys Aerosystems, owner of S-TEC, makes autopilots and avionics (HelisAS, Auto-Flight) — a Core-tier partner of Avionik Straubing. Its S-TEC autopilot service and certification scope closely mirrors Avionik Straubing's autopilot workshop and STC activity.

Emerging players

• FreeFlight Systems: FreeFlight Systems specializes in ADS-B and situational awareness avionics with significant overlap to Avionik Straubing's GA retrofit offerings. It is a Minor partner and competes in the same ADS-B mandate-driven upgrade cycle.
• Sandel Avionics: Sandel Avionics makes terrain awareness and primary display units for helicopters and fixed-wing aircraft. As a Minor partner of Avionik Straubing, it overlaps in the certified retrofit display and alerting segment.

Broad incumbents

• Garmin Aviation: Garmin is the dominant GA/Business Aviation avionics OEM (G1000, GTN, TXi, GFC) and Avionik Straubing's most important Core partner. Both sell and install overlapping products, but Garmin's scale and direct dealer network dwarfs the boutique shop.
• Universal Avionics: Universal Avionics is a larger certified avionics manufacturer (FMS, SBAS, displays) for Business Aviation and helicopters. It competes with Avionik Straubing's development and STC capabilities at a larger scale across the same retrofit and forward-fit segments.

Regional players

• RUAG Aviation: RUAG Aviation is a European aerospace MRO with deep certification breadth (EASA Part 21J, 145) and a similar mixed military/civilian avionics scope. It is a geographic peer for European-level avionics retrofit, certification and MRO bids.
