quick question

First off i read a very interesting Article today Good ol Pratt & whitney they makes of the famed PT6, are devolping an engine to replace the pt6 a totaly differnt design. that to me is liek WOW becuase the pt6 has been around for ever and now there looking for ways to replace her.
Anywyas my question is about High Floation VS Standered. Iv heard when you upgrade to high floation you have to change gear doors tires everything. becuase they are bigger etc. Now what is High Floation? and how is it better vs standered ?
