Tost internal Winch
Who out there uses the Tost winch for rewinding the rope into the tow plane?
What procedure do you use? Do you stop at the end of the rope, then start up again when ready to launch, or do you have a slow 'rolling' start. Do you have problems with 'jerking' the glider and overrunning the rope? We need the weight of collctive experience--no 'armchair experts' please. We use a PA-25-235 Pawnee, paved runway, shared with power and parachute traffic. Thanks -- Hartley Falbaum, CFIG, etc, ASW27B "KF" |

There is a sign for "roll until the rope is tight" and another sign for "rope is tight, take off now". Normally, attaching the rope is the last point on the checklist. This means when the rope is attached, the glider is ready to go. This usually results in a "rolling" start, but there is always the extra signal for "take off now". Without this explicit sign, the tug has to stop at the end of the rope and wait. This is the case when there's power traffic on final. (We have a power runway and a glider runway side by side. It's the wingrunners responsibility to ensure that there's no traffic in final. No parallel operation.) Do you have problems with 'jerking' the glider and overrunning the rope? Never had a problem, but we operate on grass. On paved runways, you will have to use the brake. Stefan |

Hi Brian,I fly a Husky with a winch in it (no tost, but similar).I use the same procedure as you described it, except
that I canīt see the winch, but we painted the last meter (approx. one yard) red/white, which I see in the mirror and we do have marks on the runway, which give me a rough indication how much rope is still on the winch.However, I still have one question. Why do you think that towing with a winch is not as fast as towing/landing without a winch and with the rope attached?I donīt see a difference, as you have to take out the slack/pull out the rope in both cases!?Regards,Markus |

I pretty much agree with BT. The only reason landing with the rope
might be faster than the winch is in the situation where the towplane can land or taxi up from behind the glider. I have seen this senerio used quite a bit. The Ground crew just carrys a hay hook and grabs the rope with it and starts pulling the rope over to the glider while the tow plane continues moving ahead. The tow plane does not stop until it is nearly all of the slack is out. The Crew then hooks up the glider and the tow plane moves forward a few feet to take up the slack. If the glider is ready the tow will commence as soon as the slack is out. This is faster only because the towplane does not have to stop for the crew to retrieve the glider end of the rope.
