Emergency Mindset(s)

Some time ago, Tom Knauff issued a list of things that could go wrong
with an aerotow launch. He pointed out that most could be avoided by
somebody outside the glider noticing and drawing the attention of the
pilot etc. to the issue.

Checking that the spoilers are closed (Airbrakes in UK terminology,
for most gliders) is on the list.

It might help some people to look and check a bit better, so here is
the list. Feel free to let me know of anything else that might be
added to it.


I have added a few items to Tom’s list, including things specific to
car or winch launching. I hope Tom does not mind me publishing the
consolidated list here.

Items 1-41 are cribbed from From Thomas Knauff, well-known USA gliding
instructor and safety specialist
