Can the gear warning be tested when NOT in flight (i.e. glider in the cradle)?

From the menu stack, info / sensors screen.  Scroll down to find switch inputs.  These will indicate N0 when open, N1 when closed.

I use spoilers on takeoff.  When the alarm goes off just hit the go button.  Alarm is silenced.  You don't even have to turn it back on.  when you close the spoilers it resets itself.

Here are some notes on the gear warning system...

A typical “flight” consists of the following states and transitions

 

1)            Sitting on the ground (not flying: IAS <25kts, with undercarriage down and airbrakes closed)

a.            IAS > 25kts

2)            Flying, launch not complete

a.            undercarriage is put up

3)            Flying

a.            undercarriage is put down

4)            Landing

a.            IAS < 25 knots

5)            Landed

a.            Timeout for 1 minutes

6)            BACK TO STATE 1

 

You get "GEAR!" warning anytime spoilers are open and the gear is up

You get "SPOILERS!" warning if spoilers are open and the launch is not complete

"Launch complete" state is set when you are flying and gear is up and spoilers are closed

"Launch complete" state is reset when not flying (ie: IAS < 25kts) for a few seconds

 

It will be confusing if:

•             The pitot/static sensors are not calibrated and you manage to get IAS of >25kts sat on the ground

•             You don’t know about the 1 minute timeout.  This is necessary so you don’t get a spoilers warning on the ground run after landing.

 

You can test the whole system if you have the glider on a belly dolly and can give the pitot more than 25kts of pressure.

 

For people that need to open their spoilers on takeoff clicking BR (or GO) cancels the warning (until the brakes or gear changes state).
