Allowing a bidding program (or any other app) on the Company iPad does not imply it is approved for use in-flight. You can put movies, videos, and music on your Company iPad but you're not supposed to be using them when you're the PF or PM.

Besides, I get way too engrossed in doing my bid to even think about working on it when I'm supposed to be flying the airplane. I suspect I'm not the only one with this operating limitation...
