Hi all,

This is about a 70% tech question and 30% flight sim question so I will post it on both boards.

On FS, you can go under EFIS and get those red boxes that mark the glidepath on an ILS approach. Can you get those boxes on a real aircraft??

You can have heads up display (I think Alaska is the only airline who has it installed on there aircraft), although it is EFIS, it is not what most people think of when they here EFIS. When you say EFIS people think the screens infront of the pilots.

Not that I know of -- Not on airliners anyway. I know of one system from Sierra Flight Systems which is based in Boise, Idaho that offers this feature superimposed on their EADI that not only simulates ILS beams but also offers it for any runway that is listed on the Jeppesen nav database. The only difference is that it's blue instead of red.

The system is aimed at the high-end General Aviation market and is currently being certified by the FAA. I have seen it working on an experimental aircraft and it is quite impressive. This system consists of two displays each capable of displaying the PFD info (ADI, spd tape, alt info and other guidance cues that look uncannily like an F-18 HUD); flight plan map that offers waypoint navigation "powered" by GPS; and electronic engine displays. On top of this, 3-D terrain and obstacle data are superimposed on the PFD display that are quite accurate (with GPS position).

Regards,
Nut

So if you wanted to fly an ILS approach, you would see the boxes if the aircraft had a HUD?

Note; Horizon have had HUD on their Dash 8s for years.
EFIS is the screens on the instrument panel," electronic flight instrument system". HUD is a separate term and system.

Yes you would see the boxes on the HUD.
AVT007 but the HUD is also falls in the catagory of Electronic Flight Instrumentn System.

Ianhol...Yes you would see the boxes on the HUD.

I beg to disagree with you. Technically you do have ILS guidances but not in the form of the boxes MS FS98 style that USAFHummer is talking about. Both the BAE and Flight Dynamics HUD (the two most used on airliners) provide guidance by having the pilot put "a big circle on top of a smaller one", not having the aircraft flying through a bunch of boxes.

Best Regards,
Nut
