Skky,
There are several companies out there specializing in custom departure procedures (and they are affordable).
hmmmm...my favorite to use is a company called
Operations Based Navigation!
There are only a few airlines which have OEI procedures in the FMC, and they have been associated with RNP procedure designs. There is one for Burbank, so they didnt have to limit weights on hot days...
and I am glad that you realize that SID, or the missed approach on a plate is not OEI.
I mean you could use them, as long as you calc out OEI performance with temp, and unload the aircraft!
