Do your straps up tightly for winch launches!

Doug,

the reading of an ASI is very rarely connected to winch launch accidents,
and certainly not in the initial climb.
Sliding back in the seat (or movement of a seatpan) during initial rotation
has already claimed a number of lives.

Wouldn't the exact effect depend on the relative areas
of the pot pitot and the usually very small holes in
the T.E. probe? The AAIB are normally very thorough
in their investigations, so I am happy to believe them,
and that this error was not the primary cause of the
accident. Neither am I recommending that you should
connect your instruments up in this way.
No, the area of the openings would not matter, unless there was a
significant leak.

If your description is correct, then I would not assume that the
primary cause was the straps, which as you point out could not be
conclusively determined due to post impact damage. Can you check the
report again and make sure you have correctly reported the results?
