You have the (rare) experience of a pilot. Therefore I would suggest you think about making iPhone, iPad and Android apps for pilots (i guess most of them use iOS). Start with really small ideas (virtual horizon, display pitch, etc.) and grow to more sophisticated projects (eg. flight planning and so on). There is a lot of money to be made on those platforms; pilots are willing to pay for tools that help them, and non-pilots don't know what they need and can't easily produce such apps out of the blue. I bet you would also easily find a co-founder once you have concrete ideas / concepts.
