Ice conditions can change faster than you think.
Fish schools and current changes can make weak spots in one day.
One warm sunny day can produce surface run off which makes small holes larger and weaker.A piece of debris can take the suns rays and turn the spot into a weak hole.
Be aware of ice fishing area's. where a fish house was removed ,
An ice chunk may be left as well as a large spear hole.
Some ice ops seem more forgiving, more room, more time to decision point.Drifts are less on the prevailing winds shoreline.
Make a pass dragging the ski's and pass thru to take a second look for slush in the tracks.Slush has prevented departure for many Ski planes.
A tip for landes 3600 wheel Ski's.
The tail wheel can be removed if you depart and land on snow.
Emergency procedure, If its the only way to fly off a certain condition, like slush, The center hole can be covered by a piece of aluminum between the wheel and ski when the tire is deflated,
and re pumped just to hold the plate in place.
I like flying over good ice on large lakes. Its a good feeling knowing there are options. Following shorelines in northern Mn. Ontario lakes, you can catch wolf / deer kill and Eagles on kills at times.Keep the camera ready when sneaking over the tree lines low onto the ice.
Happy Winter Flying
