Thanks for the replies.
The aircraft are old (MD's) and the type is not well supported by Big B with regard to performance; I requested a copy of the FPPM and was told they don't do soft copies for that a/c and I would have to buy the paper one for 500USD!. The cost of getting them involved, purchasing scap packages and their lovely software would mostly likely cost more than getting a good provider.
I'm too busy right now anyway to be able to dedicate any time to an in-house solution.
Thanks again,
D.O.G
