I think the best alarm would be the alarming fact that you are not
climbing well on tow (if at all) and that when you look out at the spoiler, you SEE that they are up! Of course a preflight checklist would prevent having to rely on any alarm. |

That things like that have not been done is one reason that the WC concept has not been successful: a more important factor, I believe, than the choice of a particular design. Jack |

So, If I wanted to fly world class for 2 weeks a year I would have to buy a PW5 rather than say an ASW20 and accept that I would loose out on a large amount of fun for the other 50 weeks of the year. Guess you havent heard of hiring huh :-) Here is an interesting fact - hiring a PW5 in either NZ or Nitra would have cost you more than renting a Ventus 2 for a proper World Gliding Champs. |

As a former 1-26 owner, why am I not surprised?
Soaring is going to die a well deserved death, killed from within, not from outside influence. Lennie, I see you still havent got a life yet. When are you going to go gliding again? Come on over, I will take you gliding, it may get rid of all that negativity you display towards our sport/hobby. If you are not interested in gliding then please sod off and leave us alone. I do not post on Lathe websites, as I am not interested in them. Neither do I post on bird-watching websites, again as I am not interested. Do you see what I am getting at? Owain |

Perhaps if the PW5 didnt look like it does there wouldn't be as much debate about the world class? I think the overall idea of the single design class etc. was well founded with great intentions, but after seeing the selection of platforms which were put forward to become the single design; i'd have probably asked them all to 're-tender'. If a design which looks similar to a current std class glider were put forward at the cost and specification of the pw5 (with perhaps at slightly better performance), i beleive it would have been a more rousing success. Back in reference to the thread, Jon's original post says it all... A glider with 1940's performance made for a single design competition at a y2k price that looks like the pw5 is destined to failure in gliding and will never represent 'value for money'. I beleive it would have been far easier to try change the design of the PW5 or similar than try and socially engineer the gliding populis's ways and personalities. Chris ;-) |

lots of links in your chain then.

I test the circuit before each flight. My spoiler warning curcuit rigged between the landing gear and spoilers on my Jantar. The switch for the landing gear only opens if the landing gear is down and the button on the handle is fully up, indicating a positive lock on the landing gears. The switch on the spoilers only opens when the spoilers are in the fully locked position. To test, I depress the button on the landing gear handle and pop the spoilers a little. This activates the gear warning by closing both switches. Just in case one of the switches fails during flight, causing the alarm to go off, I can deactive the system to avoid a beep-beep-beep on a long flight. I have a toggle switch mounted high on the panel to power the circuit. Right next to the switch is a large red LED. If I chose to deactive the gear warning system, the red LED goes on.

"K.P. Termaat" wrote in message ...
Probably my explanation was not good enough. The airbrake microswitch and the switch of the pressure transducer are in series. However with no pressure (glider on the ground) the switch of the pressure transducer is closed and opens reluctantly when pressure comes on (glider rolling for take off). So this system gives a warning for airbrakes unlocked (or open) prior to take off; it does not give an alert when flying with normal speed and airbrakes open. See my figure 5 of http://home.wxs.nl/~kpt9/gear.htm Karel, NL That seems to be exactly the opposite of what would be required by most pilots. There is no hazard associated with having the airbrakes unlocked when the glider is not in motion. The hazard starts when the airspeed gets high enough for the airbrakes to suck open if not locked. Cambridge 302 alarms at about 25kts (not sure of exact figure) if airbakes not locked. I hear it on about half my launches with ballast as I use airbrakes for better roll control. Andy |
