The aircraft is a rear-engined, T-tail, business aircraft with low swept wings and small underfin. The super-critical computer-designed wing uses three-dimension air-flow technology to provide improved performance throughout the flight envelope. Double-slotted Fowler flaps are operated hydraulically and permit landing approach speeds as low as 100kt. Flight deck The flight deck of the 400XP accommodates two crew and is equipped with a Rockwell Collins Pro Line 4 EFIS electronic flight and information system with a three or four-tube colour primary flight display and multifunction displays.
