View over the nose (proper seating position) (Read 1165 times)

Whenever I get a new plane, the first thing I do is go into the config file and adjust the eyepoint to provide a comfortable view over the nose.   I am wondering how many "degrees of ground" it is appropriate to see over the glareshield.  This is always an issue because with limited vertical screenspace, I obviously want to be able to see all the primary instruments, but at the same time, don't want the horizon to be an inch from the top of the screen!
To put this another way, when an average pilot is sitting in a plane (say a pa-28 or cessna 172), how many degrees can he pull the nose up before the horizon aligns with the top of the glareshield?

It would vary by aircraft.  Even a Cessna 172 and 182 are noticeably different in my opinion.

When flaring in a real "plane" do you ever come close to covering up your view of the runway center-line?

That is quite possible in many taildraggers.  Like in my first reply, it really varies from airplane to airplane.  Some airplanes have good views over the nose, some don't.

Well, at the risk of looking like Brett Henderson's signature, here is what I'm using for a PA-28.  Keep in mind that the airplane is already at an attitude of +5 degree due to the stoop of the main gear.  Does this look about right?  I don't have a frame of reference for the real world in regards to this, so I'm just guessing, and trying not to stray too far from whatever the defaults were for this airplane.  My zoom factor is .85, which I have decided upon for all my airplanes as the best compromise, from big ones to little ones.

I'm curious as to where you have the eyepoint set longitudinally... if I were to set the view at 85% and put the eye point about where it is in RL (just in front of the headrest), I wouldn't have anywhere near that much view, to the sides, anyway.

At any rate, what you show there looks about right, as compared to RL... although the panel would appear closer. But I think the human eye has a wider field of view than the sim- even with the panel taking up more of the foreground, it's usually quite easy in RL to determine where the runway edges are, with your peripheral vision.

Without Track IR, I find it very difficult to simulate what can be seen in RL, and I don't like to move the eyepoint around in flight, especially during landings...so my usual compromise is to set the zoom at about 70%, and set the eyepoint about where it would be in RL. This works pretty well with most sim models, but with taildraggers and some large "trikes", I may have to bump the eyepoint up on final, or while taxiing, to simulate "craning your neck".
Sometimes, if it is an open-cockpit job, I might do what biplane pilots often do, especially with a passenger in the front seat: lean my head out over the side to see past the nose.

Seeing past the nose is very important when landing, because as long as it is possible to do so, just before touchdown you need to concentrate on the far end of the runway. Being able to see that point is more useful, for keeping you centered, than the peripheral view. It's also the best focal point for judging your attitude at touchdown.

but when flying something like the Lockheed Vega, I just line it up best I can and hope for the best.  Grin Maybe RL Vega pilots were able to lean forward and see a little more, I don't know.

My only very slight critcism of your picture is that you have yourself on the runway centerline rather than the aircraft center.  Contrary to previous opinion, peripheral vision is extremely important - take it from one who has instructed many hours from the back seats of cubs, champs etc.  When the flare is started and we're feeling down the last few feet into the three point, you can either admire the student's haircut or watch out the sides hoping it all stays the same Smiley.

I have a 3 screen setup, and my eyepoint is ahead of the headrest, zoom is .85, and I'm translated down somewhat from the default view for this plane.  The virtual yoke is directly center of it all.  The outer two screens are essentially in the periphery of my vision.  This is what I see on my center screen:

Close enough.  In a normal touchdown, the high point of your nose cowl would be slightly above those trees on the left side of the departure end and your mains would be touching at that point - assuming the gear was down  Smiley.

Being a short person, back when I was flying the Cessna 172N, the glare shield often comes close to covering the whole view for me during the final second or two of the flare.  That screenshot you posted above seems a bit too high from my point of view... though I've never been in a piper.  I normally have to straighten myself a bit before I can even see the nose of the plane.  I'm 5'7" btw.
 

Cheers,

Used a cushion in my Pacer and I'm 6'  Smiley.

Had I used a cushion, my feet might not have reached the rudder pedals!  Cheesy
