gear up warning trip switch

BIG WARNING on using L-Nav as your gear warning system.
You only have one volume knob and it controls volume for ALL functions, en mass.
If you like to turn down the volume of your vario when entering the pattern to land, you will be turning down the volume of your gear warning alarm also.

Major strong point of newer systems, like the S80, is that volume adjustment is distinct for each alarm or audio function. Thus, if you turn down the volume of the vario when entering the pattern the volume of the gear warning will not be affected.

Wish I could have helped.

But don't fly with your gear down - you may just retract it in the
pattern before landing then. In the Air Force it was mandatory to give
a gear check call over the radio to receive landing clearance. Get into
the habit of using a written checklist which includes a gear check and
make that radio call. And look at the gear lever before making the call
and afterwards, as well. It takes less than a second. And make sure
the Up and Down positions are clearly labeled so there's no confusion
should you get into a rush.

Sorry, I've scoured my hangar and can not find the switches I offered to

I have a complete system, never installed, that I picked up somewhere
back in the early 90s. It includes two micro switches, a battery
connector for a 9-v radio battery, a piezo horn, and an ON/OFF
switch. It's all wired together, but can be taken apart to use a
switch in your own installation. Frankly, I'd wire it into ship's
power without a switch. Just one more thing to forget.

Send me your address and I'll send it to you for free (assuming I can
locate it, I think I know where it is). I'll need postage if you're
not in the US.

I broke the gear up warning trip switch on my glider. It was
positioned near the landing gear mechanism and had a wire that
actuated a warning sound.

Des anyone know a source for a replacement?

Thanks,

My current set up is for a micro. I was just going to duplicate what
was there. I'm not sure how to set up the reed?

Thank you Dan, that is a very generous gesture and I truly appreciate it. I have a L-nav as one of my flight computers and as I understand my manual it also can be used as a gear up warning but. I don;t understand how to use it. I also have thought about the opportunity for the switch failing and having to fly with gear down.

Since my knowledge of how the wiring is weak I choose to just replace the existing switch.

Thanks again Dan,

Dennis

If I can add to Dan's excellent advice, make it a habit to retract the gear immediately after releasing from tow - and checking it! I bet everybody flying a retract gear glider has had the experience of getting distracted when releasing and forgetting, usually leading to a friend asking on the radio if there is a reason your gear is hanging! But I have also seen a pilot (in a new glider) cross over the field after an XC flight, with the gear obviously still down, then RETRACT IT on downwind. A quick radio call from the ground corrected the problem, fortunately, before an expensive short landing roll/slide.

Even better, IMO, if you have a nose hook, is to retract the gear while still on tow. I bring up my wheel passing through 1000' on tow; one less thing to worry about when releasing low into a tight little thermal...

I saw a very experienced national champion (or near to it) kind of guy land gear up after a several hour soaring flight. During the tow he'd been asked if it was ok for the trainee tow pilot to practice descending on tow (with compensation on the tow time) and this had somehow led to him forgetting to put the gear up.

I second Kirk's, suggestion. I bring mine up at 200' as the reminder for the impossible turn

Dennis,
Send me a picture of the switch you need to replace along with some rough dimensions. I've got a bin of switches that might hold something close enough to be a replacement. Reed switches are a fine solution too, but if you're just looking to replace what you have let me know by PM. nimbus3mail at giant search domain mail service dot com

Cheers,
Craig
