Electronic Yaw Alarm?

Maybe I can get my wife to supply the voice.

OUCH! What'd ya do that for??? #@$&!!@

An Electronic Slip Detector would be quite easy to construct using contacts
either side of the T+S 'slip-ball'. It would have to have one tone for a
deflection to the left and a different tone for the right.

As for the universal Slip-String, remember, it only shows if the front of
the glider is slipping.... the tailplane is most likely doing something
else !

How about a sticky note on the instrument panel that
say's.............Hey You, don't make any slow uncoordinated turns
from base to final...........OK?

I had a Yaw String alarm once. It worked great, his name was Larry.
It's amazing what enough yelling from the back seat will make you stop
doing. Sometime later during check ride a Designated Examiner asked
me to skid the airplane in a turn at a safe altitude, and I had a
difficult time doing it correctly. My favorite Yaw String Story was
when an instructor announced "My Aircraft" and took over the controls
briefly and then gave them back to the student without further
explanation. During the post flight debriefing the student inquired
as to why the aircraft was taken away from him. The instructor's
reply was "Oh I just wanted to check the Yaw String, to make sure it
wasn't broken".

I do find it extremely irritating when the yaw string gets stuck while
in the air. Years ago when flying my ASK-14 out of Hope BC I took off,
noticed it was wrapped around the B-tube, so I landed, untangled it
and took off again............I heard about that from the guys there
for the rest of that trip............something to the effect of an
"elitist"!

I realize that anything can happen to anyone at any time, especially while flying. Failure to maintain adequate flying speed, failure to properly coordinate a turn, flying with ones head up ones rectum all can lead to problems resulting in disaster, but aren't we carrying this to an extreme?

I am far from the most experienced glider pilot on this forum and I certainly don't have the technical, engineering or assembly background to create a device such as suggested herein but it would appear that we are trying to complicate the passage of bowel gas. I've seen my yaw string depart during flight, I've flown with a malfunctioning airspeed indicator, I've flown with the thrill or victory, the agony of defeat and the heart break of psoriasis, all without losing control.

To be honest when I started flying gliders I was surprised that there was no stall warning indicator. It would appear to me that such a warning would be preferable to a yaw warning. What I love about flying a glider is that by and large it is seat of the pants flying but the seats of our pants are becoming less and less sensitive as we rely more and more on items that will inform us when our flying skills are below the line.

While I am in favor of anything that will improve safety, especially when in proximity to other gliders I am wary of becoming dependent on things which replace simplicity with complexity. Besides, the glider port at which I fly has about 500 yards of yarn and plenty of tape. Thank you very much.

BTW, I like Karl S's idea of adding 10 knots to your pattern speed every decade. Some of you would now be doing 120 when you turn final.

Part of me wonders just how much value it would add to have an alarm
go off just when someone is under stress turning to final at low
altitude where it's causing them to try to skid the ship around.

I'm with you Jonathon, an alarm at a critical time may just add to the
confusion (panic) I remember the gal that released from tow at 1000
feet, then tried to land doing something like 100 knots! She overflew
the entire length of the runway, then tried to make a
180.................stalled and killed herself! Her oxygen bottle had
been turned off after she check it for normal operation. leaving just
enough O2 in the line to run the M&H regulator for a few
minutes...........then it sounded the "low O2 pressure" alarm. Not
being all that familiar with O2 use, she panicked thinking it was
essentioal.

Just fly the airplane, most experienced glider-guiders can feel when
the ship is being flown too slow.............listen to what it is
telling you. I have twice gotten too slow turning final (both times
doing an off-field landing). The H-301 started to shudder (low
elevator was getting dirty air coming off the wing). In the LS-6, I
checked the landing spot while flying about 45 knots, then lowered
the gear, pulled on landing flaps, cracked the spoilers and turned
down-wind. The ship mushed and I got a wing rock....................It
was telling me that I needed to add some speed before deploying all
the draggies.
Just fly the airplane,

I am doing 120 when I turn final...if I am flying a 2-32!

Hey! Why don't we re-visit the AOA string on the side of the canopy?
Tick marks for pattern, best L/D, and stall? Bumper, can your Mk IV
Yaw string be adapted for use as a Mk IV AOA String? And put one on
each side as your heads up display for left or right patterns?

In all seriousness, too close to stall is far worse than not perfectly
coordinated. If you combine the two, well you might have a bad day.
Really don't think a new audible warning system for a skid is a good
thing.

Just throwing in another 2 cents worth.

I think the logical evolution would be a "Takeoff Warning". It would sense
tension on the tow rope and begin yelling, "Warning! You are about to
takeoff! Any lack of skill or cunning, lapse in judgment, or poor attitude
will place you at risk of severe injury or death!"

Then any sane pilot would simply pull the release and go home safely. If
there are still those dumb enough to actually attempt to fly one of these
unsafe contraptions, an upgrade to the system could be programmed to pull
the release automatically.

C'mon people - just fly the aircraft. Competence can never be replaced by
safety devices.

Maybe not this particular device, but we all should know that statement
is very wrong, and I don't want to discourage people from thinking about
better safety devices.

Step outside this little world of soaring, and think about why the
automobile fatality rate has dropped so much over the last 50 years. The
majority of the improvement comes from safety devices like divided
highways, seat belts, crush zones, and other improvements in safety devices.
