"Training on grass" - I though this was going to be a whole different topic.......
Interesting article linked to above by the guy with lots of numbers in his name. I was actually very encouraged to see his advocacy for transmitting a 'Mayday' call ( not meant to provoke an "aviate, navigate, communicate" debate....) as this call seems to be something of an anathema to our US colleagues, in both big and small 'tin', who prefer to say they are "declaring an emergency" (typically when prompted by ATC). Pity he then went on to say the following:
Transmit “mayday, mayday, mayday” over the radio (in some parts of the world it’s “pan, pan, pan")
a) "pan' and 'mayday' are different levels of severity of problem, and b) in the civil world it's "pan-pan, pan-pan, pan-pan". "pan, pan, pan" is, or certainly was, used by military crews - probably because in the FJ world there's better things to do with the time when things are going bad.
