Great thread! Two thoughts:
1. First, with regards to "why" vs. "what", with every passing decade we learn more and more about how human brains work, and many of the discoveries reveal that what we have always THOUGHT just ain't so. For example, several studies (no, this isn't an April Fool joke!) have shown that risk-taking behavior is strongly affected by physiology. For example, you're more likely to take the risks of a low save if you happen to prefer spicy foods! (See http://www.nbcnews.com/health/your-l...udy-6C10851877) Maybe the 'chuckleheads' are unfortunately addicted to jalapenos . . . and just can't help it. And you simply can't 'un-teach' an individual's fundamental neurology.

2. Second, on the question of what is a proper 'safe' altitude for the XC pilot, the answer, I believe (based on 50+ years of soaring experience, including 35 as a CFI) is the famous "IT DEPENDS". Over an airport in the pattern? Over unlandable terrain? Over a large, flat, open field? In a 1-26? In an ASG-29? No wind or strong gusty wind? I strongly believe that teaching 'standard' numbers for such situations is a cop-out by instructors who're reverting to the simple teaching of rote (the lowest level of learning).

As to a clear metric, yes it depends. Rules of thumb need to be carefully evaluated if they match the situation.

One thing that I think we miss in the discussion is that, from a regulatory standpoint, a low save is (again depending on the situation) a potential emergency.

In the US, §91.119 has a very clear metric on this. Unless you are INTENDING to land (or takeoff), you must remain at least 1,000 feet above any obstacle with 2,000 feet horizontal of your position in a congested area. In uncongested areas you must remain 500 feet above the surface, except over "sparsely populated areas" and water surfaces, at least 500 feet away from, essentially, persons or man-made objects.

Sorry I am quoting regulation here, but certainly something as food for thought, and if anything a guide for serial low-savers.

Jim, good point there. I have also agreed with the concept of teaching situational awareness and decision making over set and fast "numerology". I have found that using numerical guidelines is fine as a starting point in training but once a student has the basics of airmanship it is time to move on. I desire a student to be relatively comfortable without reference to an altimeter or an airspeed indicator.
This is not a popular or at least stated opinion amounst the cfi pools today but its not a radical stance and in fact, its a teaching methodology that prepares pilots for unexpected occurances. If you read any of Derrick Piggots training books you will see the same tact being expressed. Its an emphasis on what I would call "intuative airmanship". Old timers and detractors call it seat pants flying. I consider it essential stick n rudder skills.

What Jim says in 1. Discoveries regarding the brain are still happening. This study, published in June 2015, expands the knowledge of physiology related to the brain and body. Interesting that it was overlooked for so many years. Though the study relates to the physiology, it certainly opens the door to behavioral effects also in the sense of overall well-being, personal vulnerability, and attitude as part of the body's feedback loops.

I like spicy peppers and try and grow them annually. They do trigger physiological effects.

I've made some low saves from 400ft, but only where I've had the option to land, once rounding the turnpoint at the same time and field hopping on the sea breeze (UK) until I climbed out again. I believe I understand the risks. I've also bailed on low save attempts, especially after about 30 minutes where I felt the conditions and expended effort might lead to 'the mistake'. By conditions, I mean heat and undetected change in winds. 30 minutes seems to be my personal limit.

As part of the scoring team, I recall an early GPS trace (1993-1994) from a UK national's pilot thermalling at 250-450 agl for 35 minutes and getting away to complete the task, in an ASH-25. You can see where he did this by looking up Daventry, UK. It was just ESE of Bourough Hill. Plenty of landable fields, if they'd been harvested. IIRC, the contests in both years were held after the harvest was well underway.

If you're going to cite regulations, let me ask you this: Do you fly up
to cloud base? I'll wager more pilots are guilty of one than the other.

It's easy to lose track of regulatory requirements when deeply involved
in saving the flight but, as others have also said, getting to the point
of executing a low save indicates lapses in judgment further back in the
flight. To take from Nancy Reagan, "Just don't get low."

Having said that, I recall catching a thermal off a pig farm as I was
turning final to land at that farm. The lift was smooth, gentle, and
smelly, but I got away! ...Only to land out later at an airport (still
not at home).

Numbers are for non-thinkers. How does it feel? Turbulence? Wind
drift? Terrain? Narrow or wide area of lift? Airspeed? Coordination?
Any one of these things can cause a really bad day and it's incumbent on
each of us to know what is "safe" for us in a given situation. As Dirty
Harry said, "A man's gotta know his limitations."

Fly safe!

How does a Comp pilot think ?
You can loose points spending 1/2 an hour struggling and then landing time

points are important.
Find a safe field as far down track as you can and land ,stopping the
clock,better points ,less tired,and back for the next day..
I've lost points to pilots who didn't try so hard because time points
I've also lost a day fixing the ship because I put it in the wrong field .
If the days over unless that last climb is going to get you home,stick it
in a
good field ASAP it's the best points you will get.
Once you have that in your head it's easier to rationalise ignoring that
1/2knot at 700 ft .
This assumes the comp is based on time and distance

Jonathon, thats a valid point. Some of us however are engaged in a different type of competition flying involving distance and record flying. For this type of endevor, staying in the air is the paramont concern. In these instances we take the risks necessary to keep going, making distance, many times is super marginal end of the day or very early in the day conditions.

Making educated low saves in these cases are historically frequent and necessary. Given the basics as stated previously of having a field already set up etc, making low saves is a necessary skill thats is seen in every record setter especially when trying to do it in low performance ships.

One side note is, most of the lower performance ships are dang good at landing slow and consequently, can use little pea size patches to set down safely which would make a js1 or other high performance glider pilot cringe

No question "tactical thinking" affects contest scores, such "potential
effects" existing probably regardless of the set of rules under which Joe
Pilot competes.

The "type of pilot thinking" I had in mind when starting this thread was less
"contest tactical" and more "thinking as it affects Joe Sailplane Pilot's
potential for continuing existence." It's something that's long intrigued
me...might Joe S. Pilot's thought processes have a fundamental effect on his
potential for damaging glider/self to where he can't fly the same plane
tomorrow? (Hey, if George Moffat could be intrigued by pilot psychology as it
affected contests, I figure "psychology as it affects future existence" isn't
that big a stretch. Besides, I always wanted to use "George Moffat" and "I" in
the same sentence!)

I have in mind "Joe Average" Sailplane (J.A.S.) Pilot, soaring for fun on a
"routine sailplane flight" in which s/he expects to routinely (as distinct
from "overtly aggressively") challenge only the sky and his or her skill set.
In the U.S. at any rate, considering only this century, several pilots each
year manage to kill themselves during such "for fun" flights, and that
statistical toll is *after* I arbitrarily ignore fatalities "too easily
rationalizable" due to age and "stupid stuff" you or I would, of course,
*never* do.

"Low saves" were selected as a point of departure for discussing mind sets
that are generally - and maybe less generally - associated with that flight
condition, and NOT because "I have a thing for (or against) low saves."

"Generally associated mindsets" would include (say) Joe Newbie Pilot's
heightened anxiety/tenseness/nervousness due to the landing-may-be-imminent
flight condition combining with pushing their personal flight envelope. I'd
sure hope that J.A.S. Pilot would have some basic understanding of what s/he
should mentally expect the first time such a new/stress-enhancing/thin-margin
situation faces them...as surely it will and ought to be expected to.

"Less generally associated mindsets" include (in my case) active recognition
that if I get it badly wrong, - e.g. lousy coordination; "too slow" (aka too
high an angle of attack); untreated gust stall; improperly responding to (say)
wind-influenced visual optical illusion; etc. - due to my thin/may-be-thinning
ground clearance margin, I could just kill myself...as distinct from die.
Memory says I've always felt/thought that way about "flight with thin margins"
but regardless of when such thinking began, it's been a part of how I think
while soaring (and driving, and working/messing around anything - say, 120VAC
- with potential to kill me...) In other words, I think about death not as
something that "might HAPPEN" to me IF I screw up, but as something that *I*
will have done to myself BY screwing up. That awareness also doesn't morph
into fear; if I'm genuinely, I might die, fearful of something I can avoid
simply by choice, I don't do it.

I've actually talked about this aspect of thought with soaring buddies, and
it's never been clear to me if it's something unique, uncommon or common, but
I'm pretty much convinced it's not universal. Some of the more memorable
conversations involved folks who O'beer-Thirty-described their own thin-margin
situations with high-ish/active potential to kill them, but from whom I was
unable to elicit any admission they seriously recognized potential death as
anything more than a theoretical possibility. ("I'd never hose up *that*
badly!") Others seem to put black-and-white faith in their own personal "hard
deck" as if it were a talisman. ("How much altitude do I need at XYZ to get
safely out of the mountains back to Boulder?")

Without intending to pick on anyone or discount the sensibility of the hard
deck suggestion which I'll paraphrase as, "Talismanic hard deck = (height
fudge factor plus) 2x the demonstrated minimum height needed to recover from a
major wing/drop/incipient spin" put forth earlier in this thread, when I
combine the "talismanic protection aspect" which MAY accompany using such a
mental device with the potential reality of actually *experiencing* an
uncommanded departure from controlled flight "down low/close to the
above-defined hard deck," I can't help but wonder if the experience might
prove quite thoroughly more alarming than any/all practice in spin recoveries
"performed aloft." And, if that alarm may bring with it additional
flight-control-(mis-)handling problems by J.A.S. Pilot leading to the hard
deck maybe not being so talismanic as previously believed. Point being, that
thin margins are thin margins, and as such ALWAYS carry with them potential
for bad/deadly outcomes, which is one reason we generally practice spin
recoveries well above any proposed "hard XC deck" I've ever seen proposed.

Understand, I'm not "playing this mental game" out of (say) seasonal boredom,
or by way of trying to frighten people away from the sport, or a tendency to
contemplate my navel, but as a way of trying to get inside Joe Sailplane
Pilots' heads to (possibly) see if how they think matters as it affects how
they approach flying and consequently how they actually fly. While I see
"arbitrary hard decks" (and other such "shorthand guidelines") as a useful
training concept, particularly if approached by Joe CFIG with
cautionary/explanatory sharing of the hidden assumptions underlying them (the
"why" of the "shorthand what"), they - along with the rest of our training -
would seem inadequate, judging from NTSB glider fatality statistics. I suppose
it's possible we - the sailplane pilot community - have reached the
"irreducible minimum" number of annual deaths, but I'm far from convinced such
a conclusion is warranted. I know lifetime instructors (Tom Knauff comes to
mind) have their own specific training-based thoughts and suggestions as well.

Bob W.

I think Platypus once said something like "If you're considering a course of action, think about whether you would look like an idiot if it were to go wrong. If it would, you should seriously consider not doing it"

The biggest reason that I personally use a hard-deck is as the final safety check to dangerous thought processes in the cockpit. For me, it is just too easy to mentally assume all will work out and continue to push the limits of what I "feel" is safe in the moment versus what a removed unbiased observer would determine.

I think it comes back to the old saying about old and bold pilots...
