Hi,
Let me just just add couple of thoughts regarding radio usage and experiences with it in different part of the world. I live and fly in Poland where radio is installed in most probably every single glider and towplane. That's not a strict law requirement, you can fly in class G airspace without one but every flight club I know or heard of requires it with a strict "no radio - no fly" policy. Batteries "management" (for club gliders): - charged overnight, every pilot has to connect the one he used to the charger at the end of a day, - in the morning, you take a battery and check its voltage (under resistance), - mandatory radio check during pre-flight inspection. There is no standard phraseology only common practices: - towplanes use shortened call signs, one-two letters at most, e.g. "sierra faster!" (glider to towplane), - gliders use their competition numbers as call signs, - only student pilots wait for wing-rock signal to release, - pilots release when they feel it's apriopriate and signal via radio e.g. "papa november released", - usually it's stated what's the minimum release height. On a good day in my club there are usually 2 towplanes and 2 winches in use During a competition there can be 8 towplanes in use and radio communication is reduced to emergency+start signals only. Regarding open spoilers, there's always a person on the ground coordinating tows, landings, etc. and every start is observed so he can signal glider to close spoilers via radio. Of course if spoilers open later it's up to a towplane to signal it. Also more performant gliders with water balast keep spoilers open a little for first several seconds to stabilize wings and reduce risk of a wing drop. So it's guaranteded a pilot has his hand on a spoiler handle in this case. Just to summarize, in my opinio radios increase safety a lot. But of course they're not a remedy to safety problems.

![]() wrote in message ... Hand on spoiler shoud be for all flights....ballast or not.... NO! In general, you should not have your fingers wrapped around the spoiler handle on launch, any more than you should have your hand around the release handle. A bump or a startle could cause you to anadvertantly open the spoilers. The ergomatics of gliders differ, but I generally prefer to put a fist behind the spoiler lever. This assures the spoilers stay closed and (incidently) anchors my hand in the general vicinity of the release. Radio now requires additional training and practice to learn the established "standards": of radio use.... ....Which any glider pilot should be easily capable of learning...The normal method that humans use to communicate is the human voice. Nothing is simpler or more natural for us to process. Radio requires new layers of complexity to the system....such as chargers....ground personel etc... Sorry, that's just nonsense. Radios are cheap, simple to use and reliable. Further, they are necessary because we share the sky with airplanes, virtually all of which are radio equipped. It's perfectly reasonable for them to expect that we have them too. Would you have us eliminate everything from our cockpits that the Wright Broothers wouldn't recognize? Vaughn |

Nothing to argue with there. I've always felt that this was the
prudent way to use the rudder waggle. The accident that started this discussion was a cessna 150 with 150 hp with the Capstan in tow. I believe the Capstan has at least 45 degree if not vertical speed limiting airbrakes. It is approved for cloud flying. I flew it at IVSM with Shane, it took hardly any brake to make a normal approach. I wouldn't be surprised that if the brakes on the Capstan were full open the combination could not climb All I am asking is not to give a rudder wag until at safe altitude if possible. Ramy |

You're right: they're vertical speed-limiting brakes. For those who don't know the Capstan, its brakes are at least as powerful as those on a Puchacz, which also has vertical speed-limiting brakes. I've only flown a Capstan once. At the end of that flight P1 demoed the brakes with much the steepest approach and landing I've ridden through: it made a fully braked ASW-20 approach, which I've flown quite a lot, look shallow. -- martin@ | Martin Gregorie gregorie. | Essex, UK org | |
