Pro Star prepares to install Pro Line Fusion on Challengers
Collins announced the existing EFD-4077 CRT displays installed in the Challenger 604 were becoming obsolete and would be phased out after 2023. Pro Star Aviation is stepping up to the plate with CL604 retrofits.

Pro Star Aviation, an aerospace modification centre located at Manchester-Boston Regional airport in New Hampshire, is collaborating with Collins Aerospace to retrofit Bombardier Challenger 604 aircraft with the Collins Pro Line Fusion integrated cockpit.

Collins recently announced the existing EFD-4077 CRT displays installed in the Challenger 604 were becoming obsolete and would be phased out after 2023. In addition, the Pro Line 4 FMS software would no longer support the new functionality required for the new airspace requirements such as PBN, RNAV and ADS-B.

“The Pro Line Fusion upgrade brings this venerable aircraft into the 21st century,” says director of business development Jeff Shaw. “It literally leapfrogs an entire generation of avionics equipment to the current production equipment of today.”

The Pro Line Fusion upgrade provides enhanced operational capabilities, increases aircraft value and meets NextGen requirements without parts obsolescence concerns. Transition to the Pro Line Fusion will be straightforward. Baseline features include easy navigation with no hidden menus, three 14.1" widescreen LCDs, the industry's first touch-control primary flight displays, synthetic vision and optional satellite and multi-scan radar. All of these features help pilots fly with precision, safety and situational awareness.
