Be aware of the difference between an Air Transport and a Commercial Transport Operation. In this case it would only be applicable where it was Commercial Transport operation to a remote landing site
Switzerland allows a similar operation.
As to the RFS applying a 10% margin for WB Ops, that would have to be about the dumbest thing I have ever heard. It is a jettisonable load after all!!
