Turnpoint Exchange includes airspace files. The airspace files listed under Arizona Soaring Association were not provided by ASA, are not approved by ASA, and are known to not properly depict the location of the US Mexico border. In the file asa_2010_sua.sua the border is defined by the...

The key to aviation safety has finally been revealed! Who would have thought that the reef knot, which has been familiar since early childhood to anyone with the simplest knowledge of knots, could make such a difference. I had previously thought that knot tying was only of great importance to...

On a day when all but one competitor did not attempt the task, apparently due to thunderstorms, one competitor completes it and takes 1000 points. The contest is pretty much over. Are we rewarding the right behavior? Why wasn't the day devalued? Comments invited especially from the Std class...

I am using NiMh rechargable cells in my PowerFLARM portable. Yesterday, while charging, I noticed that the base of the case was hot and I disconnected the unit immediately. When I opened the battery compartment I found all cells were hot to the touch and that each was about the same...

I'd like to hear other people's experience of PCAS performance for the portable unit. I'm particularly interested in side by side comparison with ZAON MRX. Yesterday I flew my PA28-180 with both the ZAON MRX and the portable on the glareshield. Several times I saw traffic reported by the...

Several PowerFLARM purchasers have wondered about the frequency with which the FLARMnet file is updated and why the number of records in the Butterfly FLARMnet file has not changed recently. The good news is that FLARMnet folks are responsive to questions. The bad news is that you won't like the...

Can anyone comment of why Power FLARM transmit power appears to be much less than the transmit power allowed by FCC for this class of FHSS device? (ref test report on file with FCC) Is this a limitation of the RF module that was selected? Was it to increase battery life? Was it expected that...

Anyone have any inside knowledge and able to explain what this means: "A new superior display is being developed in parallel to make sure the user experience and features of portable PowerFLARM and the ‘Brick’ with remote display are the same." Superior to what? Is this display in some way...

I had a look at the on-line SSA Sailplane Directory and have to say it looks like a very nice addition to our information sources. I noticed that there were no pictures of the ASW-28 and was thinking of submitting some. I then found the conditions for posting pictures: "It is a condition of...

In a recent thread it was asserted that it was possible to get sport pilot airplane privileges without taking a knowledge test and flight test if the pilot held a private glider rating. For some reason I cannot see that thread. I had doubts that this was true and followed up with AOPA. The text...

What happened to Day 5 Unofficial? It seems to be Day 4 republished? If today is going to be rained out it would be nice to know what happened yesterday. Andy

As implemented in the latest version the maximum value of Max Altitude is limited to 15,000ft which is not useful in SW USA. It should be obvious to anyone that the limit should be setable at least as high as 18,000ft. In fact there is no reason for any hard limit at all as the pilot may fly in a...

Special thanks to John Leibacher for TP Exchange in general, and for his assistance at very short notice with creating files for an ASA club contest remote site. While working on the file preparation I was surprised to find that some Cambridge format (DAT) files on TP exchange use...

I don't know what other people do with their dead glider batteries but I have been saving mine with the intention of eventually disposing of them in a "green" way. Turns out Checker Auto takes batteries for recycling. Not only do they take full size car batteries but they also take any size SLA...

Was looking for a report of the Uvalde incident mentioned in another thread and found this: http://www.ntsb.gov/ntsb/brief.asp?ev_id=20080811X01215&key=1 Glad everyone got down ok but have to wonder why the glider and the tug were at the same altitude, and in the same place, a minute...

I noted in John's USA team Blog that he lowers the gear before rigging. I know other pilots do this too. I have to ask why. For modern glass gliders and Cobra trailers ... Reasons for leaving the gear up until the wings are on: 1. If gear is down and a hydraulic trailer jack bleeds down...

For some reason I can't reply to the old thread that discussed adding new ratings to sport pilot without a flight test. The reply option is not available. Anyway... It seems FAA has had second thought on this and has issued an NPRM. Some of it reads as follows: "Currently, to obtain additional...

Can someone please point me to the connector pin specifications for the cannon D connectors on the 302 and the mode 25 GPS NAV. I'd like to find out if the Cannon D sub connector on the 302 has the same pin specification as the GPS NAV. I could not find the info in my manuals or on the...
