Seeing over the nose

TC,

It might be interesting to note during initial flight training an instructor keep telling me to find some insect blotch on the windscreen and use it as a reference for the planes attitude along the horizon. One day we got in and I advised him the durn window was so clean I couldn't find a decent reference mark on it. He licked his thumb, stuck in on the windscreen in front of me and said, "there, use that!" as he pointed to the home made blotch he'd just made.

Ren:D

Using a sharpie on your moniter is creating an artificial HUD and is GAMEY.  The mark can always be used as an aiming device.

Creating a thumbprint on a windscreen works for only 1 head position, ie. move your head and your target reference changes.
