Longest glide?

I had one flight with two especially long glides in my Discus 2.
196km @ 85:1 (12000ft to 4000ft)
190km @ 260:1 (13500ft to 11000ft)

Not in wave, in thermals.

Actually, going further back I found a couple of better ones.

224km @ 237:1 (13500ft to 10500ft).
145km @ -856:1 (7700ft to 8300ft).

In the venerable LS4!

Turning was probably unnecessary at all on most of those days, but it's faster if you turn in the strong climbs and then cruise faster than slowing up and not turning at all. So it's a bit of a silly thing to judge your flying on really

So, I guess the question is..... "What's the longest still air glide", not, "How far did you go without turning"?

A few replies are the 2nd type, I think JSC wanted the 1st type.....

I flew with KS back from a leg to Nevada at Parowan a few years ago. I think we were cruising near VNE most of the way without a turn but there was this EERIE WHISTLING SOUND FILLING THE COCKPIT! It sounded like Yankee Doodle Dandy!ZB

Longest glide means just that, the longest glide of the flight, without any climb, typically the final glide. Otherwise this is not a glide, but straight flight with no turning, which is also interesting number when not done in wave or ridge lift.

what does this mean?

Bob, to "dolphin" is when lift (or less sink) is detected while on a glide, you pull up and slow down to gain altitude (energy) without turning. Some "S" turning is OK but the point is to not stop forward progress by circling. Especially in long-wing gliders, a final glide can be started well below the theoretical altitude needed, and by careful dolphin flying (or "bumping up" the glide) you can work your way up to a nice comfortable finish. Also works under cloud streets or along energy lines.

One has to be careful not to overdo it during fast inter-thermal cruise and pull on the stick every-time the vario beeps - this "technique" pretty much guarantees that by the time you slow down to min sink, you will be IN SINK!

So best used on days with well marked thermals (clouds, dust devils, gaggles) or late in the day when on a slow final glide and broad areas of light lift or reduced sink are common.

cool, i didnd't know there was a word for it. the book jus says "slow down in lift, speed up in sink"

What this means to me is that Ramy Yanetz is quite possibly the winner. Ramy flys a ASW 27 and in my opinion is one of the very best long range, go for it, damn the torpedos, XC thermal pilots in the world.
Very few pure glider pilots are in his league and it has been that way for a long time.
120 mile final glides from 18k in the Sierra to Byron?
His latest flight up to the far Northern California coast and then out to sea in the middle of nowhere near Ft. Bragg and return + more, raised my eyebrows for sure, again.

A Mark Holiday from South Africa also had an impressive flight some years
back. Flew Something like 300k at an average speed of 250kph without
turning. Must have been a nice convergence or something like that.

It was Friday of a regional at Sugarbush,Vt. in 1973. There were no contest days yet. In those days, Saturday and Sunday could be used to make a contest. The day looked bleak and some pilots were starting to leave. All of a sudden, a lennie appeared right over the airport. I climbed to 15,00 ft. That was the end of the lift for the day. I glided 113 miles close to the coast. It was a contest day. The next two days were good and we had a contest. Thanks lennie!
