When delaing with the posibility of having to complete a missed approach after a return from a OEI departure, a number of factors need to be considdered;
1. The OEI procedure often works on the worst case scenario........engine failure on the surface, last second airbourne and making the screen height and no more. I don't think that even with a CAT3 missed approach (from the surface in the touchdown zone) would be quite as critical..........even if the weight was the same as departure i.e. no fuel dump.
2. The minima selected for the procedure I believe should (if necessary) allow for the reduced climb performance during the missed approach and if necessary, the minima increased...........this should be in the ops manual. The standard missed approach requires a minimum of 2.5% climb which is 152ft per nm.

Old Smokey,
Yes I am aware that in most cases the OEI procedure is done following a detailed survey by qualified people. However, I am amazed by the statements here that some companies will try to make some quick home-made procedure for such a critical situation while at the same time never dream of constructing an approach procedure unless they had qualified procedure designers and a complete survey.
My comments regarding the chief pilot were designed to counter the argument made that the people who put the procedure in place don't know what they are doing - No matter how qualified (or not) the designer, it is the Chief Pilot who approves the inclusion of the procedure in the Ops Manual........and of course the National Authority (inspector) also get a copy.
