Aircraft Avionics Parts
Certified aircraft avionics touch three regulatory worlds: the TSO that approves the box, the STC or AML that approves installation in your airframe, and the FAR that governs use (Part 91 IFR currency, ADS-B Out mandate, ELT requirements). We stock avionics consumables and support parts — antennas, harnesses, racks, trays, mounting hardware — and we coordinate avionics-shop work when a full install is needed.
ADS-B Out
The 2020 mandate is in effect. All US Class A, B, and C airspace (and the Mode C veil) requires ADS-B Out. Common compliance paths:
- Garmin GTX 335 / GTX 345 — 1090ES transponder with integrated ADS-B Out, optional ADS-B In.
- Uavionix tailBeacon / skyBeacon — UAT (978 MHz) solutions that replace the tail or wingtip nav light.
- Stratus ESG — another proven 1090ES transponder path.
Panel families
- Garmin — GTN 650/750 GPS-nav-com, GNS series (legacy but supported), GTX transponders, GFC 500/600 autopilots, G3X and G5 primary flight displays, G1000 integrated cockpit.
- Avidyne — IFD 540/440 GPS-nav-com, AMX 240 audio panel, DFC 90 autopilot, Entegra PFD (Cirrus legacy).

Ordering and installation
