Ambient noise level

Business aircraft cabins are generally not quiet. Not with the turbulent boundary-layer rush of air around the fuselage at Mach 0.85 and the whine of a couple of jet engines no great distance from the comfy chairs. Then there are the pumps, hydraulics, fans, gears, actuators, electric motors, worn bearings and air distribution through the metal ductwork, not to mention the occasional hum of the microwave and induction oven, the rattling of glasses and flatware in the galley and that giant sucking sound coming from the lavatory.

Today at EBACE, Nextant Aerospace launched the $4.95 million 400XTi (the “i” stands for innovation) as the latest evolution of its remanufactured Beechjet. Compared to the 400XT, the new version introduces a number of improvements, including an all-new cabin that offers more space and reduced noise.
