ultralight accident on Lake Winnipesaukee

[Cub Driver]

The poster who claimed that a "seaplane" turned over on Lake
Winnipesaukee, NH, recently as a result of a boater's wake was a bit
wide of the mark.

The aircraft was actually an ultralight, whose pilot blamed the mishap
on the wind.

<<Bob Hirschfield, 54, of 3 Quimby Rd., Meredith, said the incident
was not a crash. "I knew I was going over so I turned the engine off,"
he said.>>

Make no mistake...

The poster who made the claim is also a troll, so I'm sure facts are
irrelevant if they do not support his purpose.

I bet he's a reporter.

don't insult the troll.

I suppose i should be insulted by being called a troll. Is that a real
"pilot" term? Funny that when i zoom around with my pilot friend in his
C-172 and he gets disoriented over the LI sound, I have to show him how to
operate the GPS. Oh well, I guess I'll just have to spend the $3500 bucks
to finish my flight training. Then will you be nice?

But thanx for the correction. It was an ultralight that into the drink,
and the pilot was rescued by boaters, as the picture shows.

I was attempting to learn about rules governing seaplane landings on the
lake, which is quite busy, but many of you people are hostile to anyone
that hasn't received their private pilot license. Sad.

dork.

No we're pretty much hostile to everyone.

It's a real Usenet term:

And the thang wasn't flipped by a boat's wake, as you claimed.

Nor was he rescued; rather, he was surrounded by the boaters.

My posting finger has a mind of its own. I meant to say that somebody
marketed inflatable floats for the Piper Cub, but the concept never
caught on because even a Cub can get up to an altitude at which the
floats began to hyper-inflate.

I wonder if it would be possible to make inflatable floats that could be
deflated once in the air to reduce drag. Maybe a little electric air pump to
inflate them again before landing?

Might be bad in case of electrical failure. What about having two "opposite"
bleeder like valves, that when there is a pressure difference, one opens up
to equalize the outside, and inside of the floats?

Well, first...what you're talking about would be simply an open passage. So
forget the "two 'opposite' bleeder like valves" idea. If you have two
valves, one of which allows air movement with a negative pressure difference
and one of which allows air movement with a positive pressure difference,
then you just have the equivalent to an open passage for air to move.

Second, for it to work, you'd need a float that worked correctly when
inflated only to ambient pressure. Most "inflatable" objects (the floats in
question included) generally maintain a higher pressure inside than ambient,
and this is what gives them structure. It wouldn't be appropriate to
operate the floats when the internal pressure is the same as ambient
pressure. You really need the internal pressure to remain at least somewhat
higher than ambient.

Third, an inflatable object is pretty good at resisting an internal pressure
higher than ambient, and a calibrated valve certainly would allow one to
maintain any specific pressure or relative pressure difference desired. But
it would be hard to get the internal pressure *below* ambient, which would
be required in order to allow external air to flow back into the object.
Without any structure built into the object to prevent it from collapsing
(such as that found in self-inflating camping bedrolls, for example), an
increase in ambient pressure would simply make the object smaller. It
wouldn't take on more air.

There are a variety of solutions to dealing with the pressure changes due to
altitude. But in general, they all involve enough complexity and weight
that you're better off just getting rigid floats if you anticipate
significant altitude changes. Inflatable floats do exist, and they are
appropriate solutions for some aircraft, but just not those that climb any
significant amount.

I looked at a T-Bird II that was forsale, it had inflatable floats that
were fed from the exhaust of the Rotax engine. Didn't look closely at
the rigging for that as it was hanging from the roof of the hanger...

The owner was deceased, but seller attested to seeing it work as setup...
