The problem as I see it with throttle mounted warning systems is the
nature of flight with our aeroplanes - many / most / almost all? flights
have an aerobatic component that would include closing the throttle such
as for spin entry. The warning system would then operate and one would
switch it off or be distracted by its operation (and forget to switch it
on again!). Using the flaps as the switch (flaps down with no gear
operates buzzer) would get around this, but if landing flapless the
system would not operate. This would be my preferred option, but is not
failsafe.
I am not electronics buff, but is there no chance of using a modified
"park distance control" unit from a car? And bumping up the range to
operate as a low range ground proximity unit ?(radio altimeter) I know
some cars (mercedes) also have a radar type unit for cruise control?
One could also then perhaps wire it to a solenoid that blocks operation
of the gear up select when on the ground, or to a microswitch so that
the second the gear up lever moves out of position a buzzer goes off?

Hi all
I've been watching the comments about gear warning
systems with interest, as this is something I'd like
to fit to my own aircraft. A few comments do come to
mind:
1) Throttle / flap switches: Simple idea, but not
entirely foolproof. At the flying school where I
learned to fly we started on Cessnas (172 or 152), and
went onto an old Piper Arrow for more advanced
training. There were several near "wheels up"
incidents in the Arrow, despite it having a
throttle-linked gear warning. The problem was that the
Arrow (that version anyway) did not have a stall
warning buzzer / horn. Pilots who forgot the gear
inevitably heard the warning buzzer on finals, as they
throttled back, but often thought it was the stall
warning (as they had heard in the Cessna). Of course
the response was to put on the power and lower the
nose, which stopped the warning. After two or three
cycles of this, they would assume that the stall
warning was malfunctioning and ignore it. I know of at
least two approaches where a sharp pair of eye in the
tower prevented an accident!
Potential solution is to integrate a synthetic voice
that actually says 'gear". This might not be too
expensive, given the cost of memory chips today.
Incidentally the SA Airforce Harvards had a similar
buzzer system for gear, not sure what they had for
stall warning.
2) Bypassing the system for aerobatics: This can be
done fairly simply, but again the problem is ensuring
that the bypass is de-activated for circuits. On
another type of aircraft that I work with we have a
similar gear warning system (throttle-linked), with a
bypass switch for deliberate low power situations. Our
safety here is that we have a two crew cockpit, and
that the position of the switch is checked by
challenge - response on the pre-landing checklist.
Nice ideas. Not entirely foolproof, but then nothing
ever is ;-)

I'm looking into the problem as we speak - will post here as soon as I have
it up and running again.
Thanks for testing,

I had some problem renewing on-line as well. I chose to pay via Pay Pal but
the system appeared to ignore my selection (Pay Pal). I did this several
times without success. It did finally work after I filled in the info in
the Credit Card section (shouldn't be necessary if paying by Pay pal). An
error message appeared saying something like ECHO data is missing or
something. It did work though. The site is absolutely great and very
professional looking. Thanks Deon et al.

ditto...
I have re-ordered the same stuff three times (slow learner) then called the
800 number at ECHO only to find out RedStar is a test account. If they ever
process my orders I'll have a dozen or so patches and pitot covers and
several renewals. Meanwhile, check's in the mail!

Troopers,
Let me try not to be long winded on this,
I had all new membership and renewals moved to the encrypted platform of the Online
Store; you now "purchase" you annual membership or renewal like you do a
ball cap or polo using a visa/MC in a fully secure ecommerce platform. Sooo easy.
However, we have store-encoded minor handling/shipping charges that apply to all
products and are added to your membership fees that you will see, the reality
is I reduced the membership/renewal fees to offset this cost. And:
I've set up for the production of membership cards for all members FAST and non
FAST, that will ship as soon as I get final competitive quotes and we go to production.
These have your name and member number, aircraft, etc. If your wondering
why we are doing this, think negotiations for rate reductions for RPA members,
national BP or FBO fuel discounts, event merchandise and fee discounts
to members...Register or renew now, as the cards ship they will be sent out by
an intrepid RPA veteran we all know...
Out.
D.B. Pointy Head.

The Harvard (and T6) gear warning system is a horn powered in series through
both gear switches, a throttle switch and a normally closed relay contact.
The relay also contains normally open contacts and serves as an automatic
re-energizing horn cut-out for low power, gear up manouvering. It is
activated by a momentary contact switch that closes the NO contacts, opens
the NC contacts and kills the horn. At the same time the relay coil is also
energized from the gear & throttle switches which keeps the NO contacts
closed until the throttle is opened. That opens the NO, closes the NC and
resets the warning circuit to energize again when the throttle is closed.
Simple and works fine.
The manual calls for a throttle switch setting of approx. 11" MAP - I ignore
that and set it about 17".
