Hawker 800XP To Get Pro Line 21 Upgrade

Raytheon Aircraft Corporation and Rockwell-Collins have joined forces to sweep the clutter out of the Hawker 800XP Pro Line 21 cockpit, as shown in this photo of the mock-up at Booth 7276. Indeed, were it not for the Hawker's familiar "ram's horns" yokes and distinctive glareshield shape, some might mistake the revamped cockpit mockup as one belonging in an all-new aircraft. Four, ten-by-eight inch flat panel displays dominate the instrument panel of the Hawker 800XP fitted with Pro Line 21 avionics, replacing the old aircraft's high-tech-antique mixture of five small CRT tubes and almost two dozen "steam gauges."

The Hawker 800XP Pro Line 21's left and right outside screens are configured as primary flight displays. The left inner screen normally is used as an engine instrument and airframe system status display, with the right inside screen used as a strategic planning, navigation display. Similar to the Premier 1, Raytheon elected to retain a conventional annunciator light panel in the center of the Hawker 800XP's instrument panel rather than equipping the reworked aircraft with a full EICAS system. Multifunction control display units at the bottom center of the panel provide FMS and radio tuning functions. The revamped Hawker 800XP most likely will be fitted with dual Collins 5000- or 6000-series flight management systems, although Show news couldn't confirm this prior to press time.

The Hawker 800XP fitted with Pro Line 21 also gets a new glareshield control panel, featuring a central flight guidance control panel flanked by left- and right-side EFIS display control panels. A new solid-state standby attitude indicator replaces the mechanical "peanut gyro" in the center of the panel.
