As I mentioned at title, I wonder how he is able to keep his head up while flying ? To be exact we are using our head parallel to ground most of the time while our body is perpendicular to ground but when tony stark is flying it is not the case, both his body and his head are parallel to ground which is very hard for a person to do, would not it cause a lot of pain in the neck ?

1Just to be clear, you're talking about how, when flying head-first, he generally has his head tilted back a bit to watch forward? And are you looking for movie continuity? Comics?– FuzzyBootsMay 27, 2016 at 18:07

Yes, btw I think it is tilted more than a bit to watch forward while flying and I'm talking about movies, here is an image of him while flying link– Berk CanMay 27, 2016 at 18:14

maybe his neck is reinforced...– ArminMay 27, 2016 at 18:23

3he is in a robotic suit - if he can redirect thermonuclear missiles...he can probably move his neck around– NKCampbellMay 27, 2016 at 18:24

1@NKCampbell: If you think about how you would do that yourself, he'd need his helmet to press against his face or forehead to keep that posture. Instead, whenever we see Stark's head inside his helmet, there is a distinct lack of face-pressing occurring.– EllesedilMay 27, 2016 at 18:26
1 Answer
As often happens when there's no explicit answer from the producers, there are a few different possibilities.
Bracing
This article explores some of the science of a flight suit such as the Iron Man suit, and notes that there would almost certainly be a system to keep the person in it in a fixed position.
The suit is likely locking Tony's legs into the appropriate position during flight. Tony's legs need to be rigid and directly behind his torso, where most of his weight is, in order to prevent him from spinning like a pinwheel instead of flying straight ahead. Leave it to Jarvis to make adjustments from there.
Similarly, it is possible that his head is locked into place during flight, meaning that, at the least, he doesn't have to employ any effort to tilt his head like that.
Camera
Another, possibly more intriguing possibility, is that he doesn't actually have his head locked into position like that. As seen in this question/answer, the scenes seem to indicate that some or all of what he's seeing is just project displays inside the helmet. Thus, he could be relaxing face-down into a pillowed headrest while the armor's head is tilted up with the view from the cameras.
Less steep angles than you might think
The image you linked seems to indicate that Tony's helmet is at a 90 degree angle to the body:
But other angles suggest that his torso is arced, meaning the head's at a less steep angle:
This further suggests bracing (since a bowed position like that would be uncomfortable to hold) as well as reducing the angle.
