Gulf Coast Avionics received FAA field approval for a significant cockpit upgrade of a Citation 501, which included new metal instrument panels designed by Gulf Coast engineers and interfaces to the legacy autopilot, radar and Tcas. The upgrade includes dual Garmin GTN 750 touchscreen GPS navcoms, dual GTX 33 transponders, GMA 35 remote audio processor, GDL 69 XM receiver and interfaces to the legacy avionics. “I really have to compliment our chief inspector, Sarah Smith, and the entire engineering and installation group,” said Rick Garcia, Gulf Coast president and CEO. “This was not an easy task, but the result is a beautiful and capable Citation.”
