In a previous article, ".Blueskies." said:
most basic flight and engine controls. Even a LSA 'amphib' with wheels
on the floats cannot change the configuration
while in flight - the wheels need to be fixed either extended (for land
takeoff and landing) or retracted for water
takeoff and 'landing'.

The makers of one flying-boat style LSA (memory says Mermaid or Merlin or
something like that) have gotten a waiver that allows Light Sport pilots
to get special training to operate the gear.

I got accused of being humorless last night. I'm considering quoting
Lieutenant Commander Data: "Perhaps the joke was not funny."
