ProTrack Manual, page 46, 'Specifications' Alarm sounds 1st warning: One 3.8 second pulsating alarm if vertical airspeed exceeds 13 m/sec at the preset altitude. Sound sequence: Pulsating, low repetition. 2nd warning: One 5.0 second pulsating alarm if vertical airspeed exceeds 13 m/sec at the preset altitude. Sound sequence: Pulsating, high repetiton. 3rd warning: Siren alarm as long as vertical airspeed exceeds 29 m/sec. at or below the preset altitude. Sound sequence: High pitch continuous siren.

You can find instructions on how to set up the Garmin ForeTrex 101/201 here. Have you set transfer mode to 'Garmin'? Which software are you using for downloading? HTH, Klaus My Logbook

Being in agreement is so GAY! Hah, I always wanted to say that to you. My Logbook

Ah, now I understand! American spelling of 'for (e) TRACKS' Unfortunately, they never upgraded the ForeTrex series to the modern SiRF III chipset as they did with the ForeRunner xx5 series. I wish they would build a ForeTrex 205, or better yet 405! I still think nothing beats the Wintec WBT-201, although I haven' tested the new Wintec WSG-1000 with display yet. K. My Logbook

I did some jumps with the 305. It works ok, although the filters are set up for running, not for freefall speeds. Therefore it tends to overcompensate when you have sudden speed/accelaration/yerk changes, i.e during opening. This ballon jump was recorded with a 305. Klaus My Logbook

Fun? Me? If it wasn't for collecting test data for Paralog, I wouldn't throw myself out of a perfectly good airplane. PS: Anyone interested in buying four barely used rare earth magnets? My Logbook

That explains why I always pass out after exit! My Logbook

Jarno, thanks for confirming this! I suspected as much when two of my bank cards were unusable after spending a day in the back pocket of my pants while flying my Blade. Although I still don't know when they came close enough to the magnets to be erased. My guess is they would need to touch or be very close. Maybe a magnetically shielded purse would make a nice addition to the Birdman clothing line? Klaus My Logbook

Now that's what I call a CAMPOS! Although you are wearing the wrong goggles. Here you go, fixed it for you... My Logbook

Long way: Right-click on the jump in the table. Select 'Copy' from the popup-menu. Paste jump into application of your choice (e.g. Word/Excel). Short way: Drag-and-Drop the jump from the table to Word/Excel. My Logbook

It seems the sig parser ignores the first markup it encounters. Insert some non-blank text or another dummy-markup fixes it. My Logbook

It seems the sig parser ignores the first markup. (url) in your case, (s) in mine. When you insert some non-blank text or another dummy-markup, it works again... My Logbook

Links are still working in my sig, but Strikethrough stopped working. My Logbook

Jen, any chance you can get a Garmin ForeRunner 305 (or similar) for this? It records heart rate together with the GPS position and has quite a decent GPS receiver, although the flight data is filtered strongly. If not, the Wintec 201 should give you what you need. Here you can find more details on how to use it in skydiving. Please report your findings! HTH, Klaus Edit: As Gadget said: The unit will normally not loose the signal while in the plane. My logbook also has several examples of complete flights captured with this unit. My Logbook

Someday? They were the norm when I went to school. My Logbook

Would they allow you to ride horses? There has been a recent scientific study showing that skydiving is less dangerous than riding a horse. Let me know if you need details, Klaus My Logbook

When climbing directly after exiting the plane, your trajectory is 'forward-up', so the AoA is less than seen on photos. Should the trajectory be 30-35°, the resulting AoA would be 10-15° and everybody on this thread would be happy Yuri, I am sure you can milk your formulas for the inclination of the trajectory for us?

This seems to be the first documented freefall photographer: Photographs Self During ‘CHUTE JUMP' FEW photographs possess such thrilling and extraordinary interest as those appearing on this page, which were taken in mid-air by a German parachute jumper during his leap through space. With a camera attached to his belt, Herr Willi Ruge snapped the shutter three times during his descent. The first two photos were taken with a camera pointing toward his head —one as he was plunging head downward before he pulled the rip cord, and the other just as the parachute opened. The third picture was taken with the camera pointed downward as he neared the ground. Owing to stringent air regulations in Germany it was necessary for Ruge and his companions to keep to themselves the bold idea of taking photographs during the descent. Although these photos are the first of their kind, the stunt has since been successfully performed by a corporal of U. S. Army Air Service. I wonder whether he bought beer ;-) My Logbook

Tried the unit this weekend @ 5Hz. To summarize, I am not very impressed: - As already mentioned by Scott, the unit is much larger than the WBT-201. - The software that comes with the unit is even worse than TimeMachineX. . Setup and log download only possible through USB, not trough BT. - Aquisition seems to be faster then the WBT-201. - On 3 jumps I could not record a single usable jump, although the unit had a fix all the way to altitude. - The unit is not compatible with Paralog ;-) I will give it another try @ 2Hz this weekend, maybe this yields usable logs. I am sure I will stick with the WBT-201, though. I wouldn't be surprised if Wintec came out with a new unit capable of logging at higher rates in the near future. Their WBT-300 already tracks @ 4Hz (no logging, though) and the GPS module used in the WBT-201 is also capable of tracking @ 4Hz... It might help to voice your interest for such a device to [email protected]. Klaus My Logbook

Paralog (currently) requires every jump to be a seperate track. I turn the unit on before boarding and turn it off after landing. My Logbook

Why don't you simply log a couple of jumps and send me the data? My Logbook

That shouldn't be a problem as the GPS streams regular NMEA over BlueTooth. You might have to use the PC version of the u-blox software to configure the device, though. I have one on the way to me

No need to buy a new GPS to record more than one datum per second if you have a Wintec WBT-201 and a PocketPC: 1. Download and install the u-blox (maker of the GPS chip used in the WBT-201) configuration software. 2. Using this tool, 2a. set the transfer speed to 57600 Bd (UBX CF-PRT), 2b. set the measurement period to 250 ms (UBX CFG-RATE) 2c. set the dynamic pattern to 5 - Airborne < 1g (UBX CFG-NAV2) 2d. enable SBAS and set it to be applied (UBX CFG-SBAS) 2e. disable NMEA sentences VTG, GLL and ZDA (UBX CFG-MSG) 2e. save the current configuration (UBX CFG-CFG) 3. Log the data from your WBT-201 during your jump with this tool (Unfortunatly, the WBT-201 can not log internally > 1Hz). 4. Load the data recorded in step 4 into Paralog My Logbook

On a PC/Laptop as well. Klaus My Logbook
