Re: [Aus-soaring] See You Flight Analysis

[Adam Woolley]

G'day John, I use SeeYou on every flight, such an awesome program for flight analysis.  I generally only look at, then compare with the top 10 placers for the day (see attached *.pdf for quickness/ease).. *Start Time (just through soaring spot) - did the winner, or general pack with 900 points start early, mid, late? *Start Height (compared to the other starters) - often you can see then if someone got a wave climb pre-start, or whether you were in the ballpark of a good start height.   - such a critical part of the flight, start high and right over your start point - IN an UP cycle.  Often these come and go every 15-20mins, so waiting for it is well worth it (unless you think that it's a distance day) *Achieved Speeds - for general interest really, as it's the points that matter! *Average Climb Rate for the day  - this a real leveller sometimes, amazing how much better the top guns can pick the better climbs *Percentage time thermalling - generally less than 30% is good - again, compare to the top 10 for the day, you might find that <20% was good for the day, or 35%!? *Alt Loss - a great way to see how quickly you're centring climbs - downside, everyone has different logging rates.  If someone flies with 1sec, they'll generally have a poor figure in this section.  If you have yours set on 10sec, often your result will look grand. - thankfully most pilots fly off 4sec, so it'll still give you a good indication of how you're going against others. *Tries - Easy way to see how much time you're losing in mucking around in unwanted climbs, that you should've just bumped and moved on.   - I record my tries like this:  6 tries, 5.5mins 'wasted'. *Netto (in cruise) - just experimenting with this one now myself.  I think it shows what the average air you were flying through was doing.   - I'm aiming to have better than 0.7kts or better each day atm *L/D - means nothing without the next part (unless flying in 18m class where all the gliders are identical in performance) *L/D Difference - I fly a Cirrus (36:1); if I get 40:1 for the day, I mark it down as +4 - then compare across the 10 top place getters for the day.  It'll then show, how I'm going in relative terms *Average Glide - keep in mind glider performance, but how do my glide distances shape up *IAS - Average cruise speed for the day.  This might show that you're flying to slow in general between climbs for the day, or about right. *Extra Distance - the extra kilometres covered in deviations. - compare the task length with the straight line distance covered - I use 7% as a number to stay within for the day.  300km task, ok to fly an extra 21km? Of course, the most can be learnt from talking with as many people as possible about the flight at the bar - often this is the best part of the day/gliding! SeeYou, WPP P.s. I just add in the start time on the left, and Netto on the right atm.

Maybe this could be broken down into practice and comps situations. Main issues would be what do you look at, and what relative importance do you place on each aspect. Has this tool provided any tangible benefits to your flying in enabling things to be done differently in the future, or do you just see it as a historical record of things past, and leave it at that.   Cheers,   John Trezise _______________________________________________ Aus-soaring mailing list Aus-soaring@lists.internode.on.net To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring
