Background:
I've been a 121 FO for about 4 years and 3000 (sic) hours. In the interest of personal improvement and possibly getting back into corporate aviation, I am pursuing my ATP certificate.

Challenges:
The challenges I foresee are two fold. One, going back to a single pilot mindset after years of having someone else set the radios and spin the bugs. Two, flying round gauges after flying glass for several years. (what's an instrument scan again??)

I'm looking at doing the 10hr program at AllATPs.

Anyone care to share there experiences or recommendations relating to earning an ATP rating?.
