Sorry to hear you ran out of Crayons, JJ. My favorite
mis-identification happend at a regionals at Lubbock. There was a somewhat frantic call over the radio 'Watch out, Zuni!!!' I was flying the only Zuni at the contest. Trouble was, my plane was on the grid and I was sitting in my crew vehicle, and my plane was totally stationary. I guess the guy in the air saw a 'Z' on a glider, and just assumed. It was a DG-600. Should I be flattered or insulted that the pilot confused a DG-600 for a Zuni? Signed, Confused |

At a regional contest in the U.S. this past spring, we had a bit of
"entertainment" on the radio. The launch was underway, with about four Pawnee's, one Cezzna Agtruck (Agwagon?), and one Cezzna 175, all towing up about 50 gliders. Over the radio: "Towplane, speed up!" Response: "Which Towplane?" Glider Guider: "The Pawnee!" Response: "Which Pawnee?" And then, I was laughing so hard, I couldn't concentrate on flying my own glider. But the play continued. "What color Pawnee?" Glider Guider: "White" Response: "Which white Pawnee? What color stripes?" Glider Guider: "I can't tell" I guess he finally got off tow. I don't know if they ever figured out which Pawnee needed more speed. Ray Lovinggood Carrboro, North Carolina, USA |

Many contests now have the towplanes put their "callsigns" on the flaps
with tape or JJ's crayon. Puts the info right where the person who needs it can see it. Helps out tremendously in case you missed looking at the N number in the heat of a contest launch.

![]() Over the radio: "Towplane, speed up!" Response: "Which Towplane?" Glider Guider: "The Pawnee!" Response: "Which Pawnee?" Funny, looking back at it. I'm laughing as well, being an occasional towpilot. But it brings to mind that in the USA, we have a signal to ask the towpilot to increase speed. NO RADIO REQUIRED. A 10 minute DVD on the Standard SSA Signals is offered for FREE by request from the Soaring Safety Foundation at www.soaringsafety.org (or get one at the SSF booth February 14-16, 2008 SSA Convention in Albuquerque.) A review of the signals is also on the SSF website, along with a wingrunner and towpilot course. Lots of good stuff on the SSF website, but safety is a hard sell, and Imust agree, not as entertaining as looking at the OLC or browsing the sailplane classified ads. But the fact is that US glider pilots must know all 18 SSA signals before solo and on glider rating checkrides. SInce those events are, for many of us, a distant memory, it's a good idea to review all signals soon, or insist upon it during your next Flight Review (oops, unless that "BFR" is technically satisfied in an airplane, helicopter, balloon, or as part of an airline job.) Glider specific procedures can be reviewed on your Flight Review in a glider or on your "First Flight" of the new year with a CFIG, as promoted, again, by your Soaring Safety Foundation. All towpilots and wingrunners must review the signals as well. By the way, if you disagree with the effectiveness of the current signal to speed up (Hint: "Rock & Roll"), volunteer to chair a committee to change it. Refer to the FAA regulation CFR 91.309 (a)(5) that basically tells us that all glider pilots and towpilots must agree on certain tow procedures before aerotow launch. This includes discussing tow speed. A hassle at a contest indeed, but a radio call before launch requesting a tow speed may eliminate the assumption on the part of the glider pilot that towpilots can read minds. A non-radio option is to have all towpilots tow at a relatively fast speed, then the glider pilot could use the "slow down" signal, (yaw or "fishtail"), which only works if the towpilot knows the signal and is checking the mirror. Make the radio call, but simultaneously perform the proper signal. It's a team effort, this aerotow bit. Learn, review, and practice the signals. This suggestion includes glider pilots, wingrunners and towpilots. Get the free DVD from the Soaring Safety Foundation, or review the signals at www.soaringsafety.org Thought for the next thread: Towpilot gives the fast rudder waggle signal just after takeoff and a majority of glider pilots - - - release. Wrong. Good luck landing your 10 to 1 brick glider. Know the signals! Burt Marfa, west Texas USA |

As a fellow towpilot I have my opinion on the visual signals.
My thoughts a It's hard enough looking in the mirror to see the glider in the first place. The mirror vibrates enough that I have to take a hand and steady it to get a be tter (not good) view. The field of view is limited and the towplane tail obscures the glider often. The towpilot is scanning many things, so the glider pilot will have to maintain the signal for quite a while to be seen and understood. The radio is quicker and easier. The issue about miss identified tow planes will only happen at contests. (Or at very busy sites maybe ?) Since the radio is the usual method of communication, the visual signals do not get practiced. Therefore they might have been memorized, but they are not practiced on every tow. I keep a placard in my cockpit, just in case. The only 2 signals that I have reliably memorized are a) wave-off by tow plane (he rocks his wing) and b) check your spoilers/glider (rudder waggle). The rest I'll take the time to look up if needed. The signals were developed in a time when gliders and tow planes didn't always have radios. Now we normally have radios and the only signals we need are the true emergency signals. Todd Smith 3S |

After calling for the sailplane to close his spoilers, the tow pilot gave the signal (rudder wag) which was mis-understood and the sailplane released at 300 feet, made a 180 degree turn and hit the wires at the end of 30. Student severely injured and instructor later died from complications relating to the accident. The radio should be the primary means of communications and the tow should not be initiated without a com check. Joe would be with us today if he had followed this procedure. JJ |

I don't really care if the signal is changed but I will never use it. If you are really too slow, trying to rock the wings enough to alert the tow pilot is not too wise. If you really can rock the wings enough to alert the tow pilot you probably aren't really too slow. At most contest I've been to, the tow speed is agreed by the tow pilot and the glider pilot by being set at the mandatory pilot meeting. True, the first day usually finds some of the less experienced tow pilots flying slow, but there should never be a need for all pilots to request a tow speed prior to launch. The frequency must be kept clear to safety calls. Andy |

![]() By the way, if you disagree with the effectiveness of the current signal to speed up (Hint: "Rock & Roll"), volunteer to chair a committee to change it. It may work if you're flying a Gollywomper, but not with a heavily ballasted racing ship. At one contest, my tow pilot hit a strong thermal and rapidly slowed down. Before I could even hit the microphone button, I had almost lost control and sank rapidly into low tow position, well below his mirrors. I had too little airspeed to rock or waggle anything, and my only pitch control was the rope holding the nose up, so I released and dropped backwards off the tow rope. I've had a few similar experiences, but would never ever try to signal the towplane pilot except by radio. Mike |

Too-slow tows are a constant problem at contests. Not being a tow
pilot, I can only guess a the problem, but I suspect that tow pilots used to pulling 2-33s can't seem to adjust to what happens with heavily ballasted gliders on a hot day. The radio is full of radio calls, wing rocking, (yes, contest pilots know the signals) and more radio calls to no effect. It happened to me last summer. The big problem was not "more speed" on a well-balanced tow. My towplane simply took off for the sky while I was still rolling on the ground! Towing a fully ballasted glider requires the towplane to gain speed while low, and make sure the glider has taken off before climbing. The contest rules say 70 mph, and that means gain speed to 70 while still in ground effect. Most hilarious radio exchange: Lubbock, standard class nationals. Full water, slight cross and downwind. The same towplane is always too slow. "Towplane X, 70 mph please. ...(no answer) TOWPLANE X, MORE SPEED (no answer) .... TOWPLANE X, I NEED MORE SPEED NOW!" (pause) "all right, all right, ... but what do y'all want to fly so fast for anyhow?" Of course many seasoned contest tow pilots provide excellent and dedicated servce, for little reward, and we're very thankful for them. John Cochrane |
