Boeing 747 Classic Gains EFIS, Courtesy of Jet Aviation
Bringing modern avionics to an older-generation airliner, Jet Aviation has
just installed the first electronic flight instrument system (EFIS)
into a Boeing 747 Classic, complete with a high-resolution, 6 x
8 in wide-angle, active-matrix liquid-crystal display. The EFIS,
supplied by Astronics Corporation of America, replaces electro-mechanical
flight instruments and provides functions of primary flight and
navigation that brings functionality associated with the current
generation 747-400. The displays, accepting digital and existing
synchro and analog inputs, are capable of receiving and processing
FMS, INAS/ADIRU, TCAS, TAWS/EGPWS, navigation radios, air data,
radio altimeter systems, weather, traffic and terrain systems. Working
with JRG Design Inc over the period of a year, Jet Aviation designed,
engineered and certified the EFIS integration and the more than
300 interfaces to achieve Supplemental Type Certification.
