Hi Maz,

My husband is an engineer and know a few pilots as well. I think a good place to start would be to go to a sight called pprune. Just google it. It is an industry website for pilots and engineers. There you can find threads and ask questions just like you have asked. The difference is that they are read by people in the industry here and else where and should know what is going on.

Good luck,

Leanne.
