Garrett Piedmont Hawthorne is now installing Rockwell Collins avionics upgrades for Citation 501s, including the Williams International FJ44-powered (Eagle II) Citation 501s. Supplemental type certification has been completed for the optional three-LCD system and an STC is in works for the standard two-display system. The standard two-screen installation features the Collins IDS-3000 integrated display system consisting of a primary flight display; a multifunction display; an RVSM-compliant ADC-3000 air data computer; integrated flight information system; an engine indicating system; WXR-800 weather radar; file server with chart and map software; Garmin radios; and an RVSM package. Estimated installed baseline price is $665,000 for the three-display system and $525,000 for the two-screen system, depending on existing equipment and desired options. The upgrade will also apply to Citation 500s, according to Michael Anderson, director of avionics for Garrett Piedmont Hawthorne. Garrett Piedmont Hawthorne has also STC’d a four-display IDS-3000 system for Falcon 200s.
