I'm having a slight bit of difficulty trying to get the HGS display to line up properly for takeoff (I can fiddle with it on landing to get the display correct by using the left, right and up arrow buttons). However, when I try to made the same adjustments for takeoff (using the same keys) the movement to the left and right is way too exagerated. Is there another key stroke method that allows adjustment of a view with a finer control?

 

Here is an example of the problem ... this is as close as I can get the display to align before takeoff ... notice the right edge is cut off.

 

Hi Charles,

 

I might be wrong, but to me your screenshot looks as if you were "sitting" too far to the right and as if your "head" was turned slightly to the left. Have you tried moving a bit to the left on the x-axis and "straighten" your line of sight?

 

Best regards,

Stefan

You're not sitting in the seat properly.  Note the yoke is not centered on the screen.

 

CTRL+ENTER/BACKSPACE

CTRL+SHIFT+ENTER/BACKSPACE

SHIFT+ENTER/BACKSPACE

...are the key commands to move you in the 3 dimensions (which is which I always forget until I start using them).

If you think about it the HUD doesn't even make sense if this kind of thing doesn't happen - it's supposed to conform to the real world outside, not to wherever your head position happens to be. Ours works exactly like the real one does - optically colimated to infinity and conformal to the outside scenery.

Uh ... Ryan ... dude ... you lost me on that one.

 

This turned out to be a EZCA issue. The view that I was using was shifted a little too far to the right. Unfortunately, there is no "fine" control over the EZCA view ... pressing the left arrow makes the view shift way too far to the left ... same thing with the right arrow and the up arrow. I simply had to shift it over and back again then back again and back again (ad infinitum) until it just happened to be in a place where I could see both tapes on the left and right.

 

Save the view and I'm happy.

Ummm, So Ryan, after that technical rendition, what are you saying so us non technical types can understand?....eg..Makes no difference in the 737NGX where your seating position is, the HUD should always be correct, or as Stephan and Kyle said, you need to be seated central to the front screen, at an 'approved' height?. I think the latter.

Ryan is saying, that the correct seating position is required to be properly aligned. Just as in the real aircraft where seating position is crucial.

A picture is worth a thousand words, so a video must be worth millions. Here's an excellent one, portraying the real-world behaviour of the HUD and showing what "optical collimation" means in practice. As you'll see, the position of the HUD graphics, most importantly the flight path marker, does not shift in relation to the world outside when the camera bobs around. You'll also notice that some shots look exactly like the picture provided by Charles in his original post. QED.

Hi Petja, Great video. Yes, this was my thought when I saw Charles post...move your position in the seat a tad because the HUD will remain true to the view outside.

Actually, there is. Using edit mode will make the controls use much more fine steps, (you can make a new view "HUD" and make sure you are positioned and zoomed properly), and there is also a setting somewhere in options that makes for finer steps.

Peter:

 

I'll have to look into that ... thanks ... as for now I got pretty lucky and was able to center the pilot's head almost perfectly so that the HGS (and the left and right tapes) are fully visible.

 

I made a cursory inspection of that ... I believe you enter edit mode by pressing Num 2 and then make the changes ... then press Num 2 again to save those changes. When I did that the -> and <- arrow buttons still jumped around a bunch. Discovering that option which allows finer control would be much more preferable than the way I accomplished it.
