Floatplanes and Skiplanes
Floatplanes and skiplanes should be secured in the same manner
as for conventional aeroplanes – to tiedown anchors or ‘deadmen’
sunk under the water or snow.
In addition to using underwater anchors, some floatplane operators
have been known to partially flood the floats of their aircraft to
keep the aircraft more stabilised in the water during windstorms.
This technique has also been applied when floatplane aircraft are
tied down on land, in this case to provide added weight.
If the storm is forecast to be severe, serious consideration should
be given to beaching the floatplane and transporting it to a hangar
or more sheltered location to be tied down.
Skiplane pilots sometimes pack soft snow around the skis, then
pour water on the snow, and allow the skis to freeze to the ice.
Although these techniques are not recommended practices, they
have proven effective in preventing aircraft damage from sudden
windstorms. Extreme care must be taken to reverse the effects of
any such measures prior to operation of the aircraft!
