To all the passengers who do not like the idea of training being done on an aircraft in which they are flying.. This has been done since time immemorial. Any pilot transitioning onto a new aircraft type will by definition be inexperienced on type. The first A380 passenger flights will inevitably have had pilots with very limited combined experience on type. Any airline with an expanding fleet will usually have pilots under training. The training Captain will normally be an experienced pilot. Sometimes, but not always, he will be experienced on type. Alternatively you may have flown on a flight where the Captain was on his first ever flight as Captain without supervision. He may have had a copilot who had only 3 months experience in the airline.
With zero flight time simulators once a pilot has passed the simulator course he is deemed to be safe in the real aircraft carrying passengers under the jurisdiction of a training captain. If passengers don't like the idea of that they should stop reading this forum, stop making comments on this forum and leave it to the professionals who know what is safe and what is not safe. A little knowledge is a dangerous thing. What is not dangerous, if done properly, is giving pilots line training on passenger carrying aircraft.
