Seems like an excellent idea. If they could be made to auto transmit position,say every 20 seconds, great! Especially as you are only seeing whats in your area. Great for pair flying and lead and follow. Come on someone, have you tried this in the air? The Rino can't be set to auto transmit every 20 seconds, as apparently one of the FCC waiver restrictions was that position would only be transmitted, once, each time the push-to-talk switch is pressed, or when a manually entered location query is received from another unit.

In my original post that started this thread, I talked about using the
Rino for "collision avoidance." Some private discussions have made me realize I should have said "proximity warning". I wasn't suggesting watching the Rino to tell when you were about to collide with the other glider, but to tell you when to spend extra time LOOKING for him. Knowing when to spend extra time scanning -- with an extra shot of adrenalin -- would probably have prevented the recent Washington fatality. And reading the description by the surviving pilot, I can see that I've been in similar situations several times. Flying with a friend, we split up to try different areas of lift, can't see each other, and aren't sure when we come back into danger range unless we tie up 123.3 or 123.5 or some other frequency -- and even that isn't possible sometimes due to others tying it up.

I suggest you use the radio in this situation. You and your friend are so close, he'll hear you, even if another glider a few miles away is transmitting. Better some unintentional noise on the frequency than the noise of a collision. -- Change "netto" to "net" to email me directly Eric Greenwell Washington State USA |

The Rino transmits a position each time you transmit. If your unit is set up
to accept polls, you can poll your buddys unit without input from the other unit. Polling is limited to one data position each 30 seconds. More data than just the other units position comes with each data burst Each unit will track up to 50 other units. It is really quite sophisticated for $150. I am interested in tracking (on the ground) several gliders racing around a lap racing course. Bill Snead Georgetown Texas |

Regarding Eric's comment below, if a glider pilot called on the radio
every time he lost sight of his flying buddy, he'd be drummed out of the soaring community for over-use of the frequency -- especially in areas like Minden where there are alot of other gliders. Even in less crowded areas, if you're at high altitude, your radio signal will interfere with other gliders over 100 miles away. While we all agree that "Better some unintentional noise on the frequency than the noise of a collision," the problem is that there are literally thousands of times we lose sight of a buddy before a collision occurs. I think that's what's so deadly about this situation. It breeds a false sense of safety (aka complacency). How many of us can truly say that he/she has called on the radio every time they've lost sight of a friend -- especially when the last time you saw him, he was half a mile away and headed away from you? But that sounds like just what happened in Washington. That's why I think we need to put some energy into several areas: 1. Getting more glider pilots to use the FRS or GMRS band for air-to-air. Clearly useful for two or more flying buddies, but if enough of us start to use it, we might be able to settle on a standard "glider" or "aircraft" frequency, much as we now tryon 123.3 and 123.5 when we see another unknown glider. 2. Alternatively, getting more glider pilots to get their ham licenses and use the 2 meter band for air-to-air communications. Opens up a lot of frequencies and 2 meters is close enough to the aircraft band that you can even use your COM antenna for the ham unit, with a relay to switch between. (ICOM sells such a device.) Getting your license only takes several hours of study of the Technician question pool, accessible at http://www.remote.arrl.org/arrlvec/pools.html Make sure you use the current question pool, not an obsolete one or one that is going into use a few months from now. (They change every so often, maybe once every few years.) The times and locations for taking ham exams is listed at http://www.remote.arrl.org/arrlvec/examsearch.phtml 3. Getting flying buddies to use Rino's for proximity warning. Again, if enough of us do that, we could settle on a standard frequency and privacy code so we could pick each other up even when not known before hand. ======== Eric Greenwell wrote in message ...
