OK, so it can turn on a quarter, instead. It's just 15 cents difference, doesn't really matter for a $300,000 airplane.Take another quote from the Rob M. article: " The A5 can turn on a dime in the air..."
Huh? Turn radius is a function of wing loading and low speed capability. The Searey clearly has a lower wing loading.
The two Icon crashes involved failure to turn on a dime and avoid the shore/trees.
It's a metaphor, not a performance measurement. The impression of turn radius will from *inside the cockpit*. This impression will be based on how the controls feel, not by a measurement of actual turn radius.
