Only if your irony on finals to Vanguard.
Just for the record Nr Fairey - you are in my opinion an excellent and clear communicator and your post has made a really eloquent and convincing intellectual and technical arguement that will of course have a dramatic impact on CAA policy and has helped educate and inform thousands of PPrUNE members.
Back to reality, I believe that since the late 90s any UK registered helicopter needs HUMS if it is to carry to carry more than 9 pax, so a S76 or As365 would need HUMS to fly to Vanguard with a full load but I believe there was a FODCOM lasy year that says the CAA are to abandon that rule for onshore operation.
