Having received several inquiries regarding my B50 plus Volkslogger
that I am offering, I've put together an email packet of information and photos. The price set is $1395 (well under 75%). If you would like to receive this, please send an email to me directly. Steve Koerner (Steve Koerner) wrote in message . com... RD: If you choose to go with the B50 (a very good instrument), I can offer a B50 plus Volkslogger system at 75% of current price. This system was removed from my glider which was sold sans instruments. Both units are in perfect operation. The Volkslogger is the new connector type. Email me direct. I can send photos if needed. Manuals are provided. Steve Koerner Mesa AZ |

If you are looking for a logger and Pocket PC system with a moving map and
reachable airports highlighted on the screen, Glide Navigator II and a Cambridge 302A will automatically calculate and display wind speed and direction. The 302A offers more memory for flight logs and waypoints than any other logger. It is very nice to never have to worry about whether your logger is going to run out of memory.

Chances are, if you don't download a flight right away you dont care too much about it. The other disadvantage of the 302a that I see is that its panel mounted.... you need a laptop or PDA to get the logs. With the Colibri, Volkslogger, and SDI Posigraph, you can bring it home and use your desktop, or take it to the scorer at a contest. Kevin |

I find the fact that our 302A is panel mounted to be
one of its main attractions (as long as you have the panel space). We don't have wires to the rear or the cockpit side to install. We never have to carry the logger around and so won't drop it, forget it or loose it. It takes a couple minutes to download the file to my old 1550 with the free Cambridge Utility programme. If my syndicate partner and I didn't have our own PDAs we could leave the PDA with the glider and just take the secure file home or to the scorer in the CF card. I used to use a GPS-NAV and carry it back ond forth like a Volkslogger or Colibri etc but I much prefer the fixed mount logger. Also the panel monted logger can be left sealed and secured in the glider (e.g.with signed paper tape) which saves the hassle of getting the OO to observe and confirm the the logger was actually flown in the correct glider - in the event of someone actually following all the security rules for badge claims. Each to their own. John Galloway At 13:12 28 May 2004, Kevin Christner wrote: ....

Hi Kevin,
I'm sure that some people will prefer a portable logger and some will prefer one mounted in the panel. The 302A works best when mounted in the panel, but there is no requirement that it be mounted in the panel. I flew with mine stowed behind me today in an SZD Junior. There is no need to view it in flight. I used double sized plastic tape to secure the GPS antenna to the top of the 302A. I also attached a RAM base with 1" ball so that I can mount it on the canopy in our club's ASK-21. It worked fine, but is a bit clunky. Another mounting solution would be to put it behind the instrument panel (not using a hole in the panel) - secured to another instrument. As someone else pointed out in another posting, a portable logger is not as nice for a syndicate because if someone takes it home for downloading it may not be available for the other syndicate partners when they need it. That is not a problem when it is mounted in (or behind) the instrument panel. You say the Colibri logs for 16 hours at 4 second intervals. That is pretty good - definitely acceptable. But the 302A can log for 25 hours at 1 second intervals. That makes the 3D flight replay very smooth in StrePla - I like that.

wrote: it is difficult to get the polar right for netto and speed to fly, and changing the polar also requires opening the case, which makes it unsuitable for gliders with multiple spans. I'll have to take issue with that and elucidate some of the design and other points of the B50 seeing as some issues have been raised. Some of these are of wider interest. Yes, you do need to open the case (unless we've set the polar for you) but you will likely do this only once. We can supply the numbers for the polar if you give us the glider type and the minimum flying weight of the glider i.e. glider, equipment, pilot + parachute, no water. Or you can derive the numbers using the B50polar.exe utility on our website. Please read the accompanying text for for "how to instructions". Don't use Vne as the high speed point, use the highest speed you would use for that weight. Don't use a speed over the "knee" in the polar for standard class gliders. The multiple span case isn't that hard to accomodate as the polar difference is small and mainly at the low speed end and while climbing. While climbing the netto and speed to fly functions aren't active and the glider polar isn't used. In straight flight the polar difference is at best about 0.2 knots Not much more than a pointer width and pretty much irrelevant operationally. In addition if you simply put in the polar for short span the slightly lower sink rate at low speeds will mean the instrument will correctly call for slightly lower speeds which makes this calculation almost self compensating. In any case at low speeds the sink vs airspeed is a very flat curve and small errors are of little consequence. You can't fly that accurately anyway. The ballast and bugs controls on the front of the B50 allow you to adjust the polar in flight anyway. You may find your glider isn't quite as good as the polar that is entered (likely as these are test flown polars with gliders in excellent condition and clean, in smooth air). Simply put in 5% bugs and this will likely fix things. Late in the day if the wings are dirty you can adjust for this easily. The control knobs mean that Macready, bugs and ballast are instantly settable without scrolling through menus etc. The netto and speed to fly both take the bugs setting into account. I really haven't had too much feedback except of the " it works great and I know what's going on for the first time " kind. Most seem happy once the polar has been set once. The vario now goes to +12/-10 knots on the indicator and +/-19.9 on the averager and the audio doesn't saturate until at least +15 knots so you can still center strong thermals. Only two holes are required for installation. They can both be 57mm or one can be 80mm for the vario indicator if you have the room. About half the people seem to have room. No big deal to bolt one extra indicator into a standard panel hole and plug in a D9 connector. The display is clear and unambiguous with great contrast and high resolution neither of which is necessarily the case with LCD type pointers. I'm always somewhat bemused by "easy installation". You install once and use every time you fly. Does anyone seriously want to compromise useability in favor of installability? Not enough panel space? Take a look at the instrument panel photo I took in flight (on our website). That is a Ventus A panel(the glider is a Ventus C a 17.6 TOP). That is a transponder at the bottom, the B40 is missing but there is still one spare 57mm hole and another 57mm hole occupied by the engine instrument. Someone mentioned the "fly faster sound". It is actually the same as "fly slower" but the two tones are alternated much faster so it sounds different. Recent B50's have an asymetric silent band for non zero Macready settings. You don't hear the "fly faster" until you are flying slower than than best glide for the air that you are in. This means it isn't as annoying in gusty air. The visual indicator still shows correct STF at all times. This is damped somewhat more than the vario. Older B50's can be upgraded. The mod is very simple. There is audio warning when you enter lift that is stronger than the current Macready setting. Custom configurations of the audio are available on special order but I'd think carefully about requesting this as what is there is pretty rational and just requires installation and connection to a good TE probe, pitot and static to work very well. We can supply a connector if you are connecting a GPS for retransmit to a PDA or B2000, or the screw terminals make field installation relatively painless. No internal logger means you can choose your own favorite brand or use a GPS engine or even a handheld GPS as GPS data source. The vario doesn't go away for logger recalibration either. There is of course nothing to stop you leaving your logger in the aircraft and downloading it to a PDA instead of taking it away. Anyway unless doing a badge or record flight or in a contest requiring IGC loggers all the PDA programs have flight loggers built in as does the B2000. If you fly cross country only for your own satisfaction or practice and want to review your flights this saves considerable money over buying an IGC logger. A casual web search yesterday turned up a GPS mouse type device that stores 15 hours of NMEA data at the one second rate. I'm sure there are others. It is relatively trivial to turn NMEA data to IGC format files. Seeing as it appears to be a sealed device if GPS altitude only was allowed, simple OO procedures make this a low cost logger/GPS source .(hint, hint) We've been in the glider instrument business fulltime for 26 years under the same ownership and management and that doesn't look like changing anytime soon. If you haven't already done so check out our website at www.borgeltinstruments.com There are some general knowledge and interest articles too. Mike Borgelt Borgelt Instruments |
