Duly noted.

I gave the dictionary a shot, this is what I got:

1. A rubbing away or wearing down by friction.
2. A gradual diminution in number or strength because of constant stress.

I could've gone further, I am sure I would've come to the right definition, but one thing I've learned in these forums is that there are a lot of "aviation slang" words, might as well cut to the chase and ask in the forum, since the first two definitions didnt throw much light at me.

Anyways, thanks for clearing it out for me.

Safe flights.
