The advent of EFIS in the Aviation Industry
The use of Aircraft EFIS Systems became a standard in almost all aircraft and was known as the standard in the Boeing Aviation Company in the late 1980s.EFIS is the abbreviation for Electronic Flight Instrument System. Moving from the rather obsolete electromechanical flight deck instrumentation display technology to the more advanced and user-friendly electronic EFI was a big step in aviation safety and security
Early EFIS systems portrayed information using cathode ray tube technology but later changed the conventional flight instruments for both pilots presented as a multi-colour liquid-crystal display (LCD)instrument display screen.
The typical system comprises of an Electronic Attitude Direction Indicator (EADI), Primary Flight Display (PFD}and an Electronic Horizontal Situation Indicator (EHSI) Navigation Display.
the Aviation Aircraft Company, Boeing was one of the first to use the Aircraft EFIS Systems in the late 1980s. starting with the Boeing 737 classic, a midsize aircraft in the 300 to 500 series. Known as the new generation which was produced from 1984 to the year 2000 delivering almost 2000 aircraft. In November 1993, feeling a threat in its market share by Airbus, on their loyal customers such as Lufthansa and United Airlines, the board of directors quickly authorized the start of the Next Generation Program in the 737 Classic series with plans to include the 600 to 900 series and to exclusively use the EFIS system especially after engineering trade studies and customer feedback discussions. The Next Generation series was launched late 1993 with almost 7000 units sold as of January 2019 with a variant called the P8-Poseidon. With the success of the Aircraft EFIS Systems running full steam ahead.
Boeing released more and more generation Boeing 737s
Business jets in its civilian side with a new design for the United States military starting with the US Navy C-40A a variant of the 737-700C and the PLAAF 737 electronic signals intelligence (ELINT) version. All because of the unconfirmed hype of EFIS. Countries across the world started and still use the 737 passenger, BBJ and cargo variants in government and military applications including Colombia, China, India, Brazil, Australia, DRC, Argentina, Chile and Indonesia and many more.
The advent of Aircraft EFIS Systems in the aviation business and competition not only in passenger airlines, cargo lines and the military since the success of EFIS have created not only safer and faster aircraft but also a huge variety for almost any possible use. The main competition in civilian aircraft design is between Boeing with almost 20 000 aircraft since 1967 and has a further firm order of almost 5000 as of January 2019 and Airbus with a comparison of almost 15 000 aircraft and a firm order of almost 6 100 as of January 2019
