Category: 4-letter acronyms[edit]

I replaced the category, as the category cannot be placed on the EFIS redirect page as suggested. As EFIS is indeed a 4-letter acronym, the category appellation is appropriate. Gjs238 15:18, 27 December 2005 (UTC)

Electronic Flight Information System ???[edit]

Are we sure the "I" in EFIS stands for "Information", and not "Instrument" ? Mdfillipp 16:11, 23 August 2006 (UTC)

I doubt "I" was mistakenly taken as "information" instead of "Instrument" too. I don't find the origin of "EFIS", but in FAA site, it calls electronic flight instrument system EFIS, though also in FAA site, it is "EFIS -- Electronic Flight Information Systems".

I knew "EFIS" from Boeing aircraft manuals, and "I" is refered as instrument exclusively. --Natasha2006 15:15, 11 June 2007 (UTC)

Electronic Flight Instrument System[edit]

EFIS form, fit, function and interfaces are defined in ARINC Specification 725, Electronic Flight Instruments. (See Lockheed 07:04, 29 August 2006 (UTC)

the two can be used interchangeably and mean the same thing... It is not possible to have a system which fits to one of the descriptions and not the other, unless one of the descriptions of the system are incorrect...

Amalgamation of this page with Electronic Flight Information System page[edit]

There is much overlap between these pages. One page could cover the topic.

To start the ball rolling, I have prepared a major edit for this page. It covers nearly all the content of the existing "Instrument" page, together with some content of the "Information" page.

Initially I have leaned a little towards theory. There is a need to add something about the sensors that feed the EFIS.

The revamped page could include descriptions of some typical display details. Ideally, this part of the topic would use lots of pictures. I have none, hence the links to brochures, etc.

  • IMHO: PFD is one class of MFD. Section "MFD" to be renamed into "Navigation MFD"... perhaps. Because MFD term has very wide meaning.--Berserkerus (talk) 19:47, 29 November 2008 (UTC)

Why not merged?[edit]

Why would not have been merged?

See my note on how misleading over in discussion of that page.

The Garmin G1000 page is already flagged for lack of ref's


Great job with this page edit. — Preceding unsigned comment added by K.Hollingsworth486 (talkcontribs) 12:23, 10 August 2012 (UTC)
