Maybe there is something to be said about JAR/EASA/Euro licenses after all. Arrive, do company SOP training (now very often the manufacturer's SOPs), 20-40 sectors line training and then on line. Not until the aircraft and country you are landing in knows what nationality of licence you hold can much else be justified. Unfortunately, every country believes they invented aviation (and conveniently forgets about Lilienthal, Cayley, Pilcher: but that's another story)so each will create and enforce their own unnecessary, arcane and pointless rules and procedures. The people who pay for this don't realise how much this costs until their national carriers face competition from operators from more enlightened nations.
