Imagine you are on tow and barely climbing (since your spoilers are out), your first thought is that something is wrong with the tow plane, and once you see the tow pilot waggle the rudder (which may also cause the wings to rock a little), I bet over 90% of pilots will release, even if they just practiced this manuver a week ago. There are many examples confirming this, luckily not all of them resulted in accidents. Bottom line: Use radios! If this doesn't work, do not waggle rudders until at safe altitude, unless the tow plane can not climb at all. Ramy |

I think the standard and enforced use of signals is the best way all
around. Too many times when things get busy, radios or mikes are dropped, misplaced, tuned off frequency or you name it. Too many clubs start introducing their own idiosyncratic signals. Standardize them. But what do I know? MSL seems logical to me, but some insist on AGL. Sometimes when reading these threads, especially if one is an infrequent follower, one comes away with the impression, "I'm glad I'm not flying with him" followed very quickly with "I'm glad he's not flying with me". Lots of emotion out there. Leave the FAA out of things. |

Thread winner, right there. -T8 No one argue against practice, but against a signal which does not work in most cases and kills people. Yes, part of the solution is to practice everything over and over again, perhaps every flight instead of doing actual soaring, but why not use better methods to adress this situation, such as radios? Every tow plane and every glider should have an operating radio. And if a radio call is not solving the problem, continue towing to a safe altitude before giving a signal. In most situations a tow plane can continue climbing slowly even with open spoilers. If this is not the case, it is probably a real emergency and there may not be enough time even for a signal.

Ramy The signal works perfectly - it can always be given and seen. If the human receiving the signal doesn't understand it, that's not the signal's fault. If the human can't understand a simple visual signal, why would anyone suppose they could operate a radio correctly? I can't understand Japanese. That doesn't mean Japanese is an unworkable language, it just means I can't understand it. Fortunately, so far, my life hasn't depended on understanding Japanese. My life certainly can depend on understanding the rudder wag so I damn well understand it. The real mystery, in fact the only mystery, is why anyone would pilot a glider when they don't understand a life saving signal. |

The statistics confirms that. Following your example, we don't use Japanese when talking on the radio (in the US), although there is nothing wrong with Japanese, right? IMHO, those who believe that they are safe since they practice and never make mistakes are at the highest risk of accidents. Ramy |

![]() The signal works perfectly - it can always be given and seen. *If the human receiving the signal doesn't understand it, that's not the signal's fault. *If the human can't understand a simple visual signal, why would anyone suppose they could operate a radio correctly? Over the years the rudder wag has been used to relay many things.I once tried to steer a tow plane and got a rudder wag (meaning NO, I will deliver you where I know the best lift can be found). For many years, the rudder wag was used to indicate "Get off now dummy, you're in a thermal". These little memories never go away, they are always there hiding in little dusty corners of our minds. If you have left the spoilers unlocked, the tow won't be going well. You know something is wrong...................when you see a rudder wag, your memory can pump out a bad snap reaction. This is exactly what happened to Joe at Minden. The tow wasn't going well, he knew something was wrong and probably suspected the tow planes engine wasn't putting out enough power. Joe had a radio, but I suspect the battery had gone dead sometime during the morning pattern tows. After repeatedly calling for Joe to close his spoilers and just after clearing the wires at the end of 30, the tow pilot gave the rudder wag. A CFI with thousands of hours instructing, pulled the plug, turned 180 left and flew into the wires. This accident should never have happened, but the point is, IT DID! How can we prevent it reaccurring? + Always do a com-check before every takeoff. + Never give the rudder wag below 1000 feet + Learn and use the proper signals. My club is religious about com-checks and the tow pilot won't start the tow until he gets a Canopy & Spoilers Closed & Locked, slack out, JJ's ready for takeoff. |
