First i would like to congratulate nitin on finally getting a picture from Chandigarh on this forum!!
Secondly i want to ask a question about Heads Up Display, if you notice the top right corner of this pic, this Gulfstream has a HUD, How come its only located on the Captains side.
Further, do any other commercial airliners come with HUD? What is the significance of such an option?
And lastly are there any regional airlines operating Gulfstream aircraft:?

Yes... several.... jetBlue has them in their E190...... Alaska has or is adding them to their B737.... I think Southwest is as well...and I'm sure there are many many more

At least a few do, like some AS 737s. The advantage is that in tricky approaches (either terrain or weather), the pilot's eyes are outside the cockpit.

Probably expense...it's typically an option, and an expensive one. Since only one pilot is actually flying, you can probably live with one HUD most of the time.

It's an option on the 737 now. Not sure about other current Boeing or Airbus production. Dual HUD's will be standard on the 787. I'm not a pilot, but as I understand the benefit is it allows the pilot to keep his eyes out the window while still getting crucial info (the HUD basically duplicates the PFD). Among other things, I believe this allows you to have lower minimums.

For a long time, it has been an option.
Air Inter, as far back as the late sixties had their Caravelle / Mercure aircraft equipped with one.
When they received their A320s, they had them fitted , too. Sadly,they were removed a few years ago as only the Orly-based airplanes had them and it was a bugger in terms of fleet training.
Here are the pics, first of a deployed HUD :
In visual flight, it used to allow for a very accurate flight path control, especially useful in mountainous terrain, haze, over the sea approaches.
On an LVP approach, it allows the captain to monitor the approach status / conditions while looking outside
On a LVP takeoff, allows a virtual vision of the runway, therefore getting very low minima.
Quoting Tdscanuck (Reply 3): (the HUD basically duplicates the PFD).
Not quite. All HUD's base their main information on the actual airplane energy, here translated into the *flight path vector* symbol....Makes for very stable approaches as you just *place* the *bird* on the runway markers.
The symbology changes on an ILS approach, on which one can visualize the ILS windows, or during takeoff where the centerline is materialised.
What is interesting is that HUDs seem to have regained a lot of favour from the bean counters : B^ having them allows crews to go down to CatIII manual flying, costing less than a redundant A/P set.
All new types :787s, 380s and 350s will have them, either as an option of as a basic equipment ( Jury is still out for the 350 where it seems to be part of the basic package).

So its a very selective option? Depending on routes flown by a particular airline? I ahve gathers from Justplanes.com that alaska flies to various unusual airports. Is that a reason?

I havent seen one in the A380 till now! Can anyoen confirm if its an option or a standard feature?
Personally i feel its a technology transferred from airforce fighters, can that be a right assumption?

AS has them on ALL of their 737's. Their M83's don't have them. WN has them on all of their 737's, IIRC. The idea of the HUD is to help keep the pilots eyes on the final approach and the instruments at the same time rather than going without the HUD and the pilot would have to look at the approach and then look down at the intruments then look up at the approach and repeat. HUD's eliminate that practice.

Alaska flies in some horrible weather. The improved ability to fly in low visibility, apparently, significantly decreases the number of flights they have to cancel or divert because of weather.

...And they make it soooooo easy to fly a precise approach down to minimums. Simply keep a small circle centered in a larger circle, and you'll fly a perfect approach.

I believe they have them on all. They first got them on the ex-Morris 733s, liked them a lot, and then retrofitted them to their whole fleet (and are now having them installed on 73Gs from the factory).

This should be an add-on to the G-IV as I don't believe it came as on option from the factory that way. The G450 and 550 have it as an option, if not standard. There are some models that will display just PFD/nav info, while others like the ones on new Global's integrate an EVS camera to display a synthetic infrared view of the terrain on the HUD as well.

Quoting HAWK21M (Reply 16): Anyone aware of the Manufacturers for the Type HUD approved on the B737s.
Back when I transitioned to the 738, AA published Marconi as the manufacturer of its HUDs. The supplier has changed names numerous times since then and I don't know who claims that title today.
Quoting 2H4 (Reply 10): ...And they make it soooooo easy to fly a precise approach down to minimums. Simply keep a small circle centered in a larger circle, and you'll fly a perfect approach.
Actually, you have to keep the larger circle (airplane symbol really) around the smaller circle (flight director symbol). And it is not "soooooo easy" as it looks. The display is so "expanded" that virtually any deviation looks large to the pilot and he will be working his a** off while the plane doesn't appear to be moving at all the those not flying --it is a common teaching technique to show new FO's what the CA was doing as they essentially see no deviations the entire approach. It also takes some getting used to as the fancy "trend vectors" often don't match trend directions (again, due to the greatly expanded displays). Still... a very good tool indeed. And yes, AA's experience is that the 737s CAT-III HUD is way cheaper to purchase and maintain than a comparable CAT-III autopilot system --and it was proven to be more accurate as well.

Ah, my mistake. My impression of the overall ease of use was based on the fact that a monkey like myself could successfully fly such a precise approach through weather in the sim.

Oh, well with "that" definition... you are correct. When AA began initial testing to determine if it wanted HUD or CAT-III for its 738s, some of the secretaries at the school-house were brought to the sim to fly CAT-III HUD approaches. They more often than not successfully landed the plane. Stopping was another matter though.

And it is great for hitting your head on while getting into the pilots seat (the joy of bieng a 6'4" mechanic). Since we don't see the 738 here. Have they fixed the problems of MU failures due to overheating?

I can only imagine. Its only taken me 7+ years, but I only hit my head once or twice a year now.
Quote: Have they fixed the problems of MU failures due to overheating?
Yes... a few years ago. Now I'll see a "system fail" msg two-three times per year. I still see OHU's overheating though that is usually caused by pilots leaving the combiner down (and the system "on") between flights --even though the checklist requires the combiner to be "stowed" after parking.
