those few pilots who actually aspire to fly a floatplane post-rating
Ho hum. I've been told my best bet is:
(a) save up $1m
(b) buy my own Beaver (because you can't buy lessons on someone else's)
(c) hire an instructor to teach me to fly it
but if I tried that on any of the bits of water round here I rather suspect that some bye-laws would rapidly get invented to ban it, so I'd have to move house as well.
(My AME has a mate in the US who has a floatplane on the lake at the bottom of his garden, so he gets a few hours a year that way. Maybe I've just got the wrong friends.)
