Mostly because it conjures up a nicer mental image than being, "Happier than
a pig in a waller". Or I ain't had this much fun since the hogs ate my little brother. -- bumper ZZ (reverse all after @) "Dare to be different . . . circle in sink."

![]() There's something I've always wondered: why are clams happy in America? And is this happy clam a shellfish or a cult member? The expression is totally American and originated in about the 1830's in New England. The original is often quoted as "Happy as clams at high tide" or similar. That's when it's difficult to dig them up and eat them! I also experimented with extra canopy strings (I had to buy about 4,000 feet of red yarn to replace a lost string, so have plenty spare). They were for ever getting trapped in the canopy and even when free weren't that useful. Anyone need 3,900 feet of red yarn? Mike |

Sorry Bill not knocking your suggestion which is technically
sound but, ASI,Altimeter, 2 varios, turn and slip, AH, compass, FLARM, transponder, radio, ELT, GPS, Palm Top, Anti collision strobe, AoA meter, logger, data link and batteries to power the above. I need a bigger glider or perhaps dispense with the pilot :-) At 21:42 09 July 2006, Bill Daniels wrote: 'Marc Ramsey' wrote in message .com... I suspect that surface ports on the top and bottom of the nose will also only work at zero slip/skid angle. Marc Why would that be? If both top and bottom ports are on the center line they should be equally influenced by slip/skid induced crossflow. You'd just be measuring the pressure difference between the ports not the absolute pressure. BTW, the guys at Black Forrest with pitch strings report they give advanced warning of lift so zooms can start a few seconds sooner. An electronic AOA indicator should do the same. Seems an AOA indicator is both a safety device and a performance boon. Bill Daniels |

I already do so to some extent, when I use the "make waypoint here" feature over a good outlanding field, then use that waypoint as my "target" for the glide computer. I've been working with digital terrain elevation data since the mid-80s. There are noticeable errors in some of the publicly available source data. Fitting data for a usable area into the memory available in a PDA requires a reduction in resolution. One also needs to consider the possibility of significant GPS altitude errors. This data is fine for drawing maps and getting a general idea of the height of the terrain, but, in my opinion, depending on it for flying a pattern into an unfamiliar field would be a mistake... Marc is quite correct, and I should have mentioned I usually add 500 feet to my reserve to mitigate the problems he mentions; also, I normally use it over relatively level terrain where the 2D resolution wouldn't be important, and it's been accurate enough. I don't exactly use it to fly a pattern, but just to get me back to the field high enough to set up a pattern in the usual fashion - "that looks about right". Now I'm curious about the accuracy of the terrain data used in my pda, which runs SeeYou Mobile. I know SeeYou itself uses "relatively accurrate" data now after the change (last year?) to data downloaded from the Internet as needed, and SeeYou's terrain data is used to produce the terrain data for the pda. -- Change "netto" to "net" to email me directly Eric Greenwell - Washington State, USA www.motorglider.org - Download "A Guide to Self-launching Sailplane Operation" |
