A few years ago the CAF's He-111 {CASA 2.111D} came to our town. I was lucky enough to watch it do a circuit and land at the downtown airport where it sat for a week. I paid to go inside it and the B-17 "Sentimental Journey" several times. Too bad the 111 was destroyed. Hope they get another flying!!

During one of the tours I noticed a piece of string in the cockpit and asked its purpose. One of the aircrew said that because of the 111's asymmetrical nose it was hard to get lined up properly with the runway, and that the string showed the aircrafts true heading.

I wanted to test this so I fired up the QMB, here are the results.

In this interior view I have lined up with the runway. The red line indicates where I feel the string should go. Sorry the runway is barely visible behind the yoke. http://farm1.static.flickr.com/156/401586757_f47a153854_o.jpg

The view from the exterior, the string position marked in red. It seems to match up pretty well. Let's compare it to the real thing.

I know I have some pictures I took of the string...but they are currently buried in boxes and are inaccessible. A quick search reveals these pictures:

Barely visible here...

Bingo! Here it is and it seems to run where I said it did:

This shows the upper anchor point.

Thank you and good day.

Interesting, thanks. That would also help with long range torpedoing I guess, since it's not so easy to line the ship up from long distances (unless you use the front gunner seat and his crosshairs http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif)

Still, there should be TWO strings, one behind the other, or some other kind of object on the plane that you would aling this string to. Otherwise it's useless, since you can look to the string from many different angles... Like mechanical aiming points on the gun: you need two.

I've always centred on a horizontal line from top the the dome in front, intersecting with a vertical line from the adjuster knob on the left of the clock !

Yeah, I see. Two strings would work great.

although at first i did think it was a raaaid style journey into string theory using the he 111 as an example
