Tail dolly hazard
The July issue of SSA Soaring magazine has a cover photo that shows at least 3 unattended gliders with the tail dolly left on. In Arizona you'd get an earfull for doing this as it puts any other glider within half a wing span at risk.
Maybe it doesn't matter at soaring sites where there are no thermals or wind gusts? Maybe it's only an issue if a wing wheel is being used? Andy GY |

Tail dolly hazard
Andy,
Being our soaring encampment at Lake Placid... I agree with you 100%. Your typical ground crew not paying attention. BTW, it wasn't that windy but no real excuse. You can't find me in the photo because I already took the first tow up and out of there... Not able to yell at everyone. : Tim Hanke Adirondack Soaring On Wednesday, June 18, 2014 12:36:24 PM UTC-4, Andy wrote: The July issue of SSA Soaring magazine has a cover photo that shows at least 3 unattended gliders with the tail dolly left on.

Tail dolly hazard
I agree for most gliders, but the Genesis-2 tail dolly must remain on at all times while on the ground. If the tail dolly is removed the wing assumes a high angle of attack and a 5 knot wind will move the ship. My dolly has a built in lock that prevents rotation and I chock both wheels if I leave the ship unattended.

With the parking brake applied the glider would be stable even with the tail dolly still on unless there was a substantial wind. That said, I do not leave the tail dolly on when the glider is unattended. |
