Avionics Modifications

Avcon offers custom Avionics installations for various aircraft. These installations replace outdated parts and systems, extending the aircraft service life and improving utility.

Example of an Avcon ADS-B installation (Garmin GTN750 in Learjet).

ADS-B For Learjets

Avcon offers various ADS-B equipment configurations for legacy Learjets. Our Garmin-based solutions integrate seamlessly with existing equipment, providing ADS-B(Out) compliance and options for ADS-B(In) capabilities.

Installations start at just $54,500.*

What is ADS-B?

ADS-B was developed as a modern replacement for radar – using satellites to provide near-real-time updates on aircraft position, heading, speed, and altitude, both to pilots and to air-traffic controllers on the ground.

ADS-B In the United States

Pending regulations require all aircraft operating above 3000 ft MSL to be equipped with ADS-B – and are expected to leave over 50,000 General Aviation aircraft on the ground, come January 1st 2020.

Haven’t scheduled your installation? Don’t worry: we install cost-effective ADS-B compliance solutions with minimal downtime, allowing you to stay in the air after the mandate takes effect.

Solutions for Any Aircraft

Avcon works with all its customers to provide the best ADS-B solutions. Our engineers can design a modification for ADS-B equipment in your aircraft and file for STC approval, or get a one-time-use STC installation license from another avionics shop (if an applicable STC already exists).

Reduced Vertical Separation Minimums (RVSM)

RVSM equipment reduces minimum vertical separation from 2,000 ft to 1,000 ft, between FL290 and FL410. RVSM equipment is required to fly at those altitudes, and can be retrofitted to unequipped aircraft to provide additional flight path options and flexibility.

Seamless Interfacing. State-Of-The-Art Components.

Avcon’s RVSM modification installs reliable, state-of-the-art components that integrate into an easy-to-read panel layout. Your existing autopilot computer may be inspected and, if necessary, repaired by an outside vendor. All components are installed with new wiring and plumbing.

The installation includes Rosemount Pitot/Static Probes, altimeters, and associated equipment, changing the existing air data sensor interface to your autopilot and flight director systems. The second-generation Kollsman ADC’s will interface seamlessly with Universal, Sandel, and other high-quality glass cockpit displays.
