Whats the difference between pan pan & and mayday?
As I understand it, pan is a step below mayday, meaning you have a serous situation, though it is not immediately an emergency. An example I know of is a pilot of a light aircraft not getting three greens on lowering gear to go into an uncontrolled strip, on calling pan pan pan he got another aircraft in the vicinity to formate with him and visually confirm gear deployment. Turned out to be a broken light circuit and the gear was down fine in this example. As he had fuel in hand, the situation was not an emergency in the pilots mind hence using pan rather than mayday, if the other pilot had confirmed a stuck up gear, he may have called mayday.
