It's not often we do dual tows, and even less often we have a tow upset on a dual tow, let alone capture it all on dual cameras!

@@jordanstclaire Yeah for sure, and that's what we train for is if your too far out of station with the tug or you can't regain control release immediately, cause the tow pilot certainly will cut you off if he has too and then you risk damage to your controls and landing with the rope attached. We were taught to release if the tow plane dipped his wings side to side get off before the 3rd dip or he'll do it. I thought my tow position was bad when I'm learning and this one jist takes the cake and that position is super hard to maintain as you and many others would know.

It could end much worse, if the rope would stuck into the aileron, blocking it in non-neutral position. I know of such an accident that happened in Poland, the pilot in similar situation wanted to shake off the rope from the wing, applied aileron and rope moved there and blocked. Sadly, that did not end well...

I worked with a guy who used to seed rice paddies in Northern California. It wasn't uncommon for large flocks of migratory waterfowl to be in the rice paddies. He taught me that when a flock of birds comes up in front of the airplane, it's best to neutralize the controls and fly through them instead of maneuvering to avoid them. The reason being to prevent jamming the flight controls. It's a lesson I've carried with me through my flying career. I include it in all of my takeoff and approach briefings where there is an increased chance we encounter larger birds. Luckily, I haven't had a flock pop up in front of me, but I did take a lone Canadian goose directly to the windscreen on short final.

Good reaction from the tow pilot. I'm quite surprised that the glider pilot was able to get so far out of position, and would love to hear the cause 'from the horse's mouth'. It's real easy to jump to conclusions that would dismiss the glider pilot's skills, but he/she is probably perfectly skilled in flying but something was omitted in this case?

Whenever a glider 'trades altitude for airspeed' it can overtake the tow plane. On a single glider aerotow this can easily happen when the glider drifts a bit higher than the towplane and then (incorrectly) pushes stick forward to return to level position. Nose down will increase the glider's airspeed (faster than the towplane) and put slack in the towrope. The correct way to return the glider to level behind the towplane is to yaw the sailplane to reduce lift and increase drag. This keeps the rope taut and restores correct position. If the glider is threatening to rear-end the towplane, glider pilot can open spoilers to increase drag, slow glider, and tauten the rope. Slack rope is commonly triggered by turbulence. We all learn how to remove it, and with practice we learn how to promptly input corrections that maintain correct position in turbulence. Since the towplane is 200 in front of the glider, it can fly into sink when the glider flies into lift (and vice-versa). Glider pilot can compensate with elevator, spoilers and yaw.

@@Paul-vh6ul I think most of us here know how that works. Still incidents occur even with extremely experienced and/or professional pilots. I think that we can assume that the pilot in this case was perfectly proficient in aerotow, because you'd never attempt a dual-tow. And still he/she got way out of position, so knowing what really happened is important to learn from the incident. Was it weather related, airflow related, human factors, who knows?

Did a lot of tugging before continuing my pilot career. The danger is when you have a lot of inexperienced pilots around you. Then anything can happen. The scariest for me was when a friend of mine was tugging a glider with the old version of a Pawnee, the one that has the fuel tank between the engine and the cockpit, the worst possible position for a fuel tank. At the start the glider pilot had not coupled the elevator correct and had not done a sufficient steering column check, so with no elevator control the glider went straight up pulling the tail of the tow plane hard up at lift off. So in fractions of a second the tow plane crashed into the ground before the tug pilot was able to release the rope. His Pawnee caught a fierce fire and my friend was burned to death in front of his two young daughters. My take from this as a tug pilot was to always,always have your eyes glued to glider at take off and your hand on the release handle.

We used to do plenty of double tows in the mountains of British Columbia moving gliders from airport to airport. The turbulence is strong and we found it much better to just stay horizontal on high tow, short glider just a bit higher than normal. The tug was then just yanked from side to side rather than up and down with the stall horn blaring. The other benefit was that in low-tow the glider would get covered in oil from the L-19 birddog tug. Not by the book, but we swore by it.

It just made me thankful that the people I did mine with (many years ago) knew what they were doing and we (ALL) were properly briefed. I would say all 3 were LUCKY they didn't end up in a spiral mess hurtling,,,, well you know. And after all that, the glider on the left (pilots facing) turns RIGHT, right into the path of the right glider, I just about freaked out. Anyway, glad you showed video 2 - I will go flying with those guys any time.

I'll prefix this by saying I have no idea what I'm talking about. But it looked like the tow plane experienced a some yaw when the tail was pulled down, so much so that the left hand glider (pilot facing) was almost directly behind the tow plane when it released. I wonder if they just wanted to get out of the way of the path of the tow plane and knew the right hand glider was quite a bit lower than them?

In any briefing with critical items the best process is using repeat back. The instructor says to the low pilot. “When the top glider moves to the center high position, you move over and assume the normal low tow position.” Then the low pilot repeats back those instructions word for word. (At a USA nuclear power plant, the instructor would repeat it back again, three way communications. It becomes so instinctive to Operators that they will do it back to their wife, usually with a bad outcome)

@Tungsten Kid to my knowledge (please correct me if wrong), a sailplane is like what is in this clip, an unpowered aircraft with a large wingspan. The term glider can include such things as motor-gliders which I have flown, which are aircraft which have a small engine but are operated similar to a sailplane and also similar to a typical light aircraft. Gliders can also include paragliders and para-motors. Most of the time, the term glider will be reference to a sailplane. I hope this makes at least some sense.

Another thing done wrong was the turn after release. The pilot in the higher/shorter position should have turned left, not right, given that the other glider was on his right. Likely a case of habit, always turning ti the right expecting the towplane to go left. The pilots should have had a prior agreement that the left glider foes left, the right glider goes right and the towplane carries on straight forward.

During the late 1970s in the UK there were a series of accidents involving gliders pulling up abruptly behind the tug with the tug's tail being pulled up often resulting in a fatal accident to the tug. The glider was, typically a Ka6E which only had a belly hook, a very light elevator and an inexperienced pilot. The BGA had asked us at Booker to investigate what happened and I was given the, unenviable, job of tug pilot in a 180 hp Super Cub. What we found was that if the glider (a Ka 13 on the belly hook) was gently climbed out of position the combination could reach a stable situation with the tow rope at an upwards angle of 45 degrees from the tug, the Ka 13 at almost full up elevator and the Super Cub still fully under control. We had a chase plane with a photographer (actually he was David Attenborough's film camera man) taking pictures of it which I still have somewhere. We later tried the Ka13 making a rapid climb and the outcome was very different. On the first one I attempted to keep the Super Cub under control by pulling on the stick. The result of this tussle was that the tug's tailplane stalled resulting in a very violent pitch down to near vertical with a fair amount of negative G (my head hit the metalwork in the top of the cabin). Since it was at 2000 ft there was plenty of time to recover and I was, of course expecting something to happen. We then tried the same manoeuvre but without me getting into a pulling match with the glider. This resulted in the tugs tail being gently lifted, the tug starting a descent and almost immediately the weak link breaking. The tug remained under control throughout. The moral seemed to be don't pull, although this obviously didn't work if you were very near the ground. The purpose of the tests, all done without radio contact bye the way, was to try to find a way of making an automatic release on the tug. Several attempts at this were made, but none were successful. The problem seemed to go away initially with keeping inexperienced pilots out of Ka6E's and later with Ka6E's being retired. The fin and rudder could also stall if the glider got violently out of position laterally (usually with a Chipmunk as a tug), but in this case the problem was self correcting as the tug assumed a new heading which put the glider directly behind again.

Years ago, I was asked to design a dual-tow installation on a Transavia Airtruk (I'm an aeronautical engineer). I used two TOST belly releases, installed upside-down so they would automatically release if either glider got too high. I flew the high glider and investigated out-of-position potential problems - the Transavia Airtruk was an unconventional layout and had two tail assemblies, and a very short fuselage, so the vertical out-of-position did not cause the tug pilot any problem, but the lateral out of position was potentially dangerous. Overall, the experiment was abandoned, because the added risks of a dual tow with any tug were far too great to justify the small cost benefit. It's a fool of an idea, been tried many times - it simply isn't worth the risk.

good thing the tow-pilot was obviously just waiting for the sh!t to hit the fan and reacted almost instantly :) plus the other glider pilot reacted great too because the upset of the towplane makes it way slower than the glider who's in upper tow and additionally in a higher position (more energy).

@BoazRosenan
@BoazRosenan Жыл бұрын
In the video with the correct dual tow, the gliders lined up behind the tow plane while still on the ground. As a result, the tow rope for the glider at the back was under the wing of the glider at the front. This means that if either the glider at the back or the tow plane would have lifted off the ground before the front glider, the cable would have hit the wing and the front glider would have tipped over, possibly doing a ground loop right in front of the glider behind it. Wouldn't it be safer for each glider to keep to the side, like the two gliders in the first video did? And then, only once in the air, would they position themselves at the center?

Yeah it depends on the experience levels of the pilots, and weather. In that last example's case they had thousands of hours flying those gliders, so no chance of the rear gliding leaping into the air. Yes you could leave the gliders separated horizontally for a bit longer if needed. Cheers!

I've towed two before there's no chance the tow is plane going to take off first. I like the in trail method, when two gliders start to the side its very hard to maintain directional control, needing a lot of rudder to stay off to the side and dragging a wing (snagging a rope) is very possible. also if the ropes in a wide V snag on weeds or clumps of grass it tends to swerve the towplanes tail causing a lot of foot work. in my opinion starting in trail is good as long as the lightest (soonest to lift off) is in the middle, lessening the chances of the rear glider pulling the rope up... the back pilot needs to be the most competent, first staying disciplined and low and reacting properly if the first glider has a rope break or the towplane upsets... largest risk is to the sailplane in the low tow position if the robe breaks or is released by the towplane where the glider has to eat the mess of rope... generally double tows lost their usefulness after WW2.

The same problem we have at our airfield. We use a microlight as a tug with one glider in tow. The Problem is that the tug has a takeoff-weight of about 420kg with a 700kg glider in tow. In case the glider pilot is not knowing what is expected of him, the tug-pilot is in big trouble. As the tug-pilot I would have released the glider earlier at minute 3:55 for an off-field landing.

Ah the good ole days where we met in a room or part of the hanger, went over checklists, verified everyone knew what position they would be in, what they should see, and gone over emergency situations and what to do. If on take off x y or z happens cut loose. if on take off, something happens, cut loose and land in these fields here, here or here. once above x feet on climb out it is safe to circle back and attempt landing at the airfield. You know, basic stuff so you are not scrambling in an emergency to figure what to do and where to land and turning to tight, bleeding to much speed, stalling out and crashing trying to be back to the airport when yo don't have the altitude to do that.

I have done many tows behind a Pawnee in my Glidinhg carreer. At our club, IE. Orient in S.A., we were instructed to always fly in Low Tow position behind the Tug on normal Aerotows. Although I have done many High tow position tows at other clubs which insist on High Tow position. Just a point that occurs to me from viewing the video. The Glider Pilot flying in High Tow position cannot see the Glider below him at any time if they assume an in-line stacked position (I.E Low tow and high tow directly in line behind the Tug.) Nail biting stuff. This double tow or multi-tow idea was pioneered in War time. Looks pretty hairy to me, I certainly would not try it unless I was at War.🙂 Interesting video, thanks Paul

I've flown a number of dual tows, and it's not as tricky or dangerous as this video might make it look! I've also flown high and low tow in Australia and NZ, and both are fine really, but with high tow you have to be much faster on the release if anything goes wrong or you get too high. Usually I'll tow with what the club usually does, because their mirrors on the tow plane will be set up for one or the other...

I'm not a pilot, yet, but I find it hard to believe that the cost savings of a dual-tow is worth the potential of something going really wrong. The lower sailplane that had the rope wrapping around the wing was really lucky that it didn't go worse than it did. I continue to wonder why someone has not designed a tow rope system that lets the tow pilot release the tow rope at the sailplane so there would never be a time when an emergency tow rope release by the tow pilot would leave the sailplane with a rope hanging from it's nose.
@gregschmidt62
@gregschmidt62 Жыл бұрын
If the sailplane pilot doesn't want a rope hanging from the nose of his sailplane, he's quite able to release the rope. There's a release at each point of attachment to an aircraft, controlled by the pilot of that aircraft. It's completely unnecessary to try to invent a tow rope system that would put the tow pilot in charge of all the releases.

So if the towplane releases, which way should each glider go? Ordinarily (at least in the US), an individual glider should turn right, and the plane left. With two gliders, both going right seems somewhat risky. Should the high tow go up and right, and the low down and right? Watching that rope wrap around the wing did not make me feel good.

In some countries/scenarios, the tow plane keeps flying straight after the rope release. If the aerotow is next to a mountain slope, the glider may also fly straight. Turning opposite directions after the release has on at least one occasion led to a mid-air collision. I once did a 180 off aerotow and found myself head to head with another glider! Now I turn 45 degrees right, and then turn immediately 90 degrees left and reestablish visual contact with the towplane asap. Then turn another 45 left and look for other gliders before completing the 180. I often want to make a 180 to return to a thermal that we flew through while on aerotow.

Perhaps that is what the guy in low right position was trying to do but traded too much potential energy for speed/and or hit a thermal. Not optimal but a non-event excepting the guy in 1st tow position broke right when he should have broken left on release.
