Accident report - PDA's can restrict emergency exit

Real glider pilots have no need for pee tubes, quick connects, funnels,
misc. plumbing parts etc. Why do you think they installed that storm window
so low on the canopy side instead of directly overhead?

Just be sure to slow to below 60 knots prior to "gear" extension to avoid
the possibility of flutter - - guaranteed to be an unpleasant experience.
Frostbite, though rare, can be nasty.

I just did some calculations considering accelerations, masses and mechanics
of materials. It turns out that if I stay connected to the pee tube and
bail out at under 103 kts, the force of the bail out will extend my penis by
2.8" before the latex tubing breaks (in colder temperatures the max bailout
speed does drop). Well, that extension of 2.8" falls just between the
elastic and yield (not ultimate) values of my penis, so after extending out
by 2.8", my penis will retract by 1.6" for a net permanent gain of 1.2"
Mind you, 1.2" is only about a 10% increase over current length, but that's
OK too. ;-)

However, after some feedback from some friends, I decided it is best to only
connect the quick disconnect when I have to use the pee tube. No need for
the guillotine.

Jim, let's not discuss spring-loaded guillotines and pee tubes in the same
thread! J

I also used male and female sterop plugs for the connections made to the
canopy.

The issue that's been bugging me is what to do with the external catheter.
In the flurry of an egress, it does take a few moments to disconnect the
QD
from the drain tubing. Maybe a winter project is a small spring loaded
guillotine below the seat pan that would cut the drain tubing.

Ever tried to pull off an USB connector by pulling across ?! Any cable
on
the canopy system is a serious thread.

I have a Volkslogger mounted on the canopy frame of our LS3a. I spliced
a
male/female pair of "mic" cables into the wire connecting it to the
battery such that they will part if the canopy is jettisoned. Some
comments:

- The screw retaining ring on the plugs has been removed.

- The cables on either side of the plugs are secured onto the support
post
and canopy frame respectively with cable ties. The geometry is such that
if the canopy jettison latch is released the load on the wires will
always
be axial which quickly pulls the plugs apart.

- There is a small loop in the cable to allow just enough slack for the
canopy to open on its "parallelogram" mechanism without the cable
becoming
tight.

- When the canopy is closed the loop forms in a location where it can't
be
easily kicked loose on entry/exit or in flight.

- A fair amount of planning and testing went into getting it to work
just right. These installations are easier to wrong than right.

I have tested it a number of times by taking the canopy off without
first releasing the cable. It always pulls out cleanly without any force
or damage. On the flip side we have yet to loose a trace due to the wire
coming loose when it is not supposed to.

My mic plugs have 4 pins, of which I am using two so there are two
spare.
When I finally get around to installing a PDA I have some options to
use the same cable for PDA power etc.

But when we installed a Flarm I avoided mounting it on the canopy
because
that would have required a second plug set for the remote display cable.
Getting this to work side by side with the existing cable looked a bit
tricky.

If I did it again I would experiment with RJ45 plugs with the
locking tabs broken off. It may be possible to mount two cables in
parallel to have enough pairs to meet future requirements.
