Hb29m 03:28, 5 January 2007 (UTC)The EFIS is not part of the FMS... in an usual cockpit setup an FMS provide data to one or more EFIS via some avionic link (ARINC 429, RS-485 or MIL-STD-1553). The EFIS part should be merged with the EFIS page. -- Sagremor 02:50, 13 November 2006 (UTC)
I am a fresh avionic software engineer and major in fms, so I am very earnest to learn lots of basic knowledge about it.Could anyone please give me a help? thanks –– Hb29m 03:28, 5 January 2007 (UTC)
Radios are taken as more precise, and are taken as the first priority in navigation(or, position location), although they are limited by some conditions like territories.
GPS is much more widerly used, and fairly precise not only in position location, but in ground speed, track and other parameter measurement. —The preceding unsigned comment was added by Natasha2006 ( talk • contribs) 21:37, 9 March 2007 (UTC).
I put it there because they have close relationship. Maybe there is a way to make it better presented. Any advice would be appreciated!
I work at an avionics company where we produce Flight Management Computers, GPS and other products. We use the term FMS to describe a single FMC or a group of FMCs in an aircraft.

The link for Rockwell Collins ( http://www.rockwellcollins.com/products/cs/br/flight_mgmt/index.html) doesn't go anywhere. GBrady ( talk) 20:14, 9 May 2008 (UTC)
"The Flight Management Computer is located in the cockpit between the pilots' seats, beneath the main panel. It's composed of two small alphanumeric keypads and two screens, one of each pilot. Twelve keys are lined up at the sides of the screen, labeled L1 to L6 for the left side, and R1 to R6 for the right side."
I doubt that this is the case of all FMC on all airplane models, including the exact names of the keys! There is no reason that the computer itself should be physically located at that place... David.Monniaux ( talk) 04:59, 2 October 2008 (UTC)

I had to add some ugly "citation needed" tag to the article where it says that FMS use 5x DME channels - any chance of linking information for this? The manual I have for an FMS system says that two DME channels are pilot-controlled, two more are FMS-controlled, and two are just there watching morse-code on the standby frequencies. Mathematically, only 3 are needed for position calculation ( Trilateration). Ojw ( talk) 21:54, 28 October 2009 (UTC)
Indeed with a standard DME (such as a DME-442) each FMS uses just one channel. But this channel scans up to 5 different DME stations (within ten seconds) and uses the five different slant ranges to determine the aircraft's position with a high level of accuracy. Only two stations are needed for position, but five stations allow significantly better accuracy and integrity of the position allowing much better ANP.
For a citation, use AVIONICS by Carl Spitzer page 20-6. I will edit the article with the citation shortly. —Preceding unsigned comment added by 66.131.221.58 ( talk) 18:44, 1 November 2009 (UTC)
