I'd always read how very bad it is to do a gear-down landing on water and the likelihood of flipping over the nose, but to see a video of it is something else... Ironically, a wheels-up landing on land in an amphibian (or on straight floats) is much less of an issue. Apparently when some Canadians take their float-planes out for the winter they just land on grass by the side of a runway on their floats. Take-off involved putting the plane on a truck and driving down the runway until rotation speed is reached - there's a video of it somewhere... -Stuart Send instant messages to your online friends http://uk.messenger.yahoo.com - Using Tomcat but need to do more?

Correct, the drag of these small wheels is enormous when they get into water at this speed, Martin. -- Unix _IS_ user friendly - it's just selective about who its friends are ! -- - Using Tomcat but need to do more?

[Flightgear-devel] terrain surface types...
Hi all , is it possible to detect the type of surface one lands on, by surface type / land cover/ or texture ? In the process of trying to design a wake / spray for the Beaver I would like to only show a spray if landing on water ... it would look a bit silly on land , and although it IS a seaplane , some (pilots) apparently take off from runways ;) . And I am adding retractable gear , but came across some interesting info while trying to find out proper operation of the gear. The gear apparently has very little shock absorption , very difficult to control/steer in a crosswind, brakes tend to fail easily and very hazardous if accidentally left extended during a water landing . now if I can just accurately model all that !
