/ TURBINE PILOT / NEW AGAIN Garmin G5000 cockpit infuses new capabilities into Citation Excels BY THOMAS B. HAINES The chime we heard over Oklahoma followed by the succinct message on the Garmin touchscreen display was something that the designers at Cessna probably couldn't have imaged when they conceived the Citation Excel in the early 1990s. When the Model 560XL was certified in April 1998 it carried a load of cathode-ray tubes in the panel as part of the then super-modern Honeywell Primus 1000 cockpit suite.
