Elliott Aviation of Moline, Ill., has received an FAA STC RVSM group approval for the Beechjet 400 and MU-300 Diamond. The RVSM solution uses the Beechjet/Diamond’s native Honeywell avionics suite. A Honeywell AZ-252 advanced air-data computer, AM-250 barometric altimeter, BA-250 barometric altimeter display and AL-800 altitude preselector/alerter replace the existing non-compliant Honeywell air data/altimetry. The project requires minimal downtime because system architecture requires very little rewiring of the aircraft, according to an Elliott Aviation spokesman.

The company has also received multiple FAA STCs for the installation of Honeywell Mark VIII EGPWS (Class A TAWS) with multifunction radar display and Honeywell CAS-67A TCAS II (ACAS) with Change 7 software. Elliott Aviation, a member of the Pinnacle Air Network, also has facilities in Des Moines, Iowa; Minneapolis; and Omaha, Neb.
