Yesterday I sat in the aft most emergency exit row on the right side of the aircraft with the flight attendant jumpseat across from me. On the taxi in I noticed the left side emergency exit door viewing window didn’t look normal. As we taxied in the view out the small window was the ground moving below the aircraft, not the horizon. Now I’d assume this is so a flight attendant on the other side of the aircraft can decide if it’s safe to use that door in an emergency. My question is, how is this window constructed to accomplish this? I didn’t have a chance as we deplaned to look at it closer. It was a bit disorienting to look at it as we moved I’ll admit.

It does the same thing but is a large circular piece of glass with a chamfered end.

Sounds like a version of a fresnel lens used commonly by HGV drivers to eliminate blind spots by the side of their lorries see http://www.truckview.net/

Interesting, thanks Cking.

It is normal. The window is a small prism, designed to allow the cabin crews to see if the area were the slide is going to deploy into, is clear of obstructions. The same type of window is fitted to the 737 doors.

That’s what I thought at first but that would require some sort of blister on the outside of the aircraft?

On a hunch, a small mirror working much the same as a submarine’s periscope?
