CIV5C. .. .I am somewhat confused by your post. Nowhere did I state that we should not discuss MNPS, RVSM or whatever you like. What I said was that someone with no training or experience in MNPS operation, which aviator4294s post clearly demonstrated, should not be operating in this area. Most airlines spend a great deal of time and money training their crews in North Atlantic operation. Discusions on PPRuNe are no substitute for this.. .. .aviator4294. .. .As well as practical training, some airlines produce computer based training courses for MNPS operation. These include procedures in the event of engine failure, weather avoidence, wake turbulence and radio failure. They also contain audio/visual briefings on all of the diversion airfields. You also need to bear in mind that once airbourne you might be rerouted. Make sure that you know how to calculate ITTs and amend the distances. Also ensure that you fully understand the track structure in case of a diversion.. .There are currently several pilots who are highly experieced in MNPS operation who are sitting at home looking for work. Why not take one of these guys with you to sit on the jump-seat. He would be worth his weight in gold if you had a problem.. .. .Airclues
