If the 747 is parked with the rear-most bogies...

at the back of the piano keys, and my eye-point is set correctly in the cockpit, where down the runway should be touching the glareshield?

For common reference, let's use RW27L at Heathrow.

I figure I have the ability to look down 13 degrees if I look at the glareshield and what is touching it. If we take the eye-point to be 40 ft high, then that means the closest point in front of the aircraft that I can see is 1 / sin(13) * 40 ft or 177 ft?

I think the eyepoint is 32 feet agl?

Not sure...now I'm looking I'm getting different answers. Seems with the aircraft sat on the ground, the eye-point from the ground, vertically to the eye-point is 26 ft.

40 ft seems to be the threshold crossing height of the gear.

I have this view set up at the moment, but not sure if it is angled down enough, and whether it is too "zoomed in" or not.

The horizon disappears when the aircraft pitches through +13 degrees.

The top of the hump is around 32'2". The eye point looks about 3'4" below this from Boeing Station diagrams. Say, around 29 feet. 26 feet is the top of the pilots floor ("waterline 312")
