A tight turn after release from tow is also a good way for the data analyst to determine when the glider released and therefore the release altitude. Pam

Subject: Re: [Aus-soaring] Altitude badge claims As it looks to be a good season with perhaps lots of Gold height claims please remember that it is for a gain of height. Identification of the low point after release is just as important as the high point. REMEMBER to NOTCH the barograph (dive down a little after release, then pull up if you released in a thermal). The flight recorder pressure altitude IS a barograph and should be treated the same. Also if you are using a longer sample interval either do a pilot event marker or make sure you stay below release altitude for long enough to get at least one point recorded. I'd hate to be unable to certify your gain from the record.
