I enter and leave my glider from the "low" side - that's the side with
the wing on the ground; otherwise, it's a noticeably higher sill to
crawl over on my ASH 26 E. The boom microphone is easily pushed to the
side of the cockpit.

I think I'd like a panel mounted directional mike because I wouldn't
have to make an effort to put my mouth close to the boom mike while I'm
looking around for clouds and traffic, and while trying to coordinate a
photo shoot with another glider.

Hi All
A Question about Boom Mics. Why are they always mounted on the right
side of the cockpit? Is there any reason for not being able to mount
them on the Left side.
Thanks

I've sometimes wondered why a highly directional mike couldn't be
mounted in the instrument panel which would be completely out of
harm's way.

I have a friend in Auckland NZ who has a mike as you describe mounted in the panel in his ASW27. It works well

Actually there is someone in Germany offering such panel-mounted
microphones for 49 EUR in the classified ads on
http://www.segelflug.de/cgi-bin/clas...lassifieds.cgi

Search for "Einbaumicro" or Ad no. 10339. I guess you also could use any
other highly directional mike from your nearest electronics supplier....

your right hand from your right side; I've no doubt someone on the web sells
swords if you don't have one handy...) On the other hand, American Plains

Henry Ford. He (sensibly, it can be argued) decided to put the driver on the
left side of the Model T because it was 'generally the custom' over here with
horse-drawn carriages to pass on the right of oncoming carriages, and
(presumably) it followed that ladies typically entered carriages from the
right side. What I've read (attributions entirely forgotten) claimed Ford
decided to continue the lady-entrance-tradition (think 'horseless carriage,'
long dresses, dirt 'roads,' and few sidewalks outside of cities' downtowns),
as both likely - insofar as the ladies would be concerned (many of whom would
have to be convinced that spending money on the newfangled contraption for
'everyman' was in the house budget) - to be cleaner (in the event of
sidewalks) and safer (in the event of passing traffic).


I also think it used to be considered unlucky to mount from the right!

Never read that one! I generally entered my Zuni (think ~6-foot-long
removeable canopy; 'AS W-12-like' landing gear) from the low side. At camps
with ramps, right-side preferred because nothing projects above the side rail;
at my home field, operations favor the left side, which requires getting
legs/butt over ~6" of projecting flap handle.

Your club's K21 is different from my club's pair, then. Their canopies
open fore and aft. Are you sure you aren't thinking of a K13, a G.103 or
even a Puchacz?

Even those with an understanding of sinister and dexter may still find
it a bit wierd.

This is mainly historical, as canopies primarily hinged on the right.
Most people put GPS, etc on the right so all of the erroneous equipment is
on the right, such that in the event of a bail out you don’t have to fight
your way over all of the rubbish.
Any equipment that is removed from the cockpit is a bonus as it frees up
the exit route. I can give you an example of someone having to climb over
the GPS stick on mount to bail out in the 20 seconds before it hit the
ground, he won’t mount it there again. Flying is about good habits, so
putting all of the excess equipment in the same place is a good practice.

Panel mounts are now fitted to a lot of new gliders in Europe and are very
good, with no issues to report.

I'm not confused, but maybe my description was poorly written:

The hinges are aligned transversely and, therefore, as the
rotational freedoms are normal to the hinge axes, the canopies
open fore and aft.

The K13, G103 and the Junior etc. have longitudinal hinges,
allowing the canopies to open "sideways".

I have, of course, once made the mistake of loosing both
catches of a Junior canopy while ground handling. Luckily for my
wallet, we operate from a grass airfield....
