Darn things work even better when you tape both ends down. Just have
to make sure it's on straight first...

And they last longer on the inside of the canopy, anyway.

No one has mentioned that yaw strings work on helicopters, too.

Just as important to avoid adverse yaw on a helicopter - and no, the
"downwash" does not render them useful.

Sounds like it would be a usefull instrument for a hot air baloon.
After all, you need to know which way the wind is blowing.

Balloons do use something similar to a yaw string. They hang a piece
of rope from the periphery of the bag down to a point level with the
basket, with a piece of yarn at the end. It serves as a measure of
horizontal wind shear, which tells you which way your path will
deviate if you change altitude.

I should read twice and send once. I meant:

Time for a soda.

The FAA RFH (http://www.faa.gov/library/manuals/aircraft/media/faa-
h-8083-21.pdf) only mentions yaw strings on gyroplanes, so I added
that. Find a ref for helicopters, and add the info to the WP article.

I do not recall seeing it written anywhere, but I am a helicopter pilot and
they are on most of the Schweizers (formerly Hughes) that I flew. The
instructors seem to like them and noted when you think you are doing fine
that the yaw string was not centered. Heck, instructors are the same
everywhere, they like to find things you do wrong and point them out - thank
goodness.

Yaw strings are also fitted to the

at altitude (the coffin corner), perhaps it isn't too
surprising.Yaw strings have also been found on USAF fighters. They aid in gunnery
training.

Same way everybody makes a small fortune in aviation - start with a
big one!

Actually, you should consider using the blank surface of the yawstring
for advertising - how about string cheese? Or baling wire?
