SAFE Winch Launching

Look, I didn't start this thread. You don't have a perfect winch and neither does anybody else. There's a LOT of room for improvements in every aspect of winch design. Keep an open mind. If you think that automatic gear changes don't matter, put a tension logger on yours for a few launches. The results will astonish you. What gets my dander up is "emotional" opposition to all attempts at innovation based on the idea that your domestic winch is 'perfect'. Sorry to ask you this again Bill, but could you please quantify what problems your alleged 'tension spikes' actually cause? We just don't seem to get weak link or cable breaks associated with gearchanges. Even if they do exist, there is enough elasticity in a 1km plus winch cable to absorb them. As you have been told repeatedly by everyone with a decent quality automatic gearbox winch, the gear changes are totally smooth and imperceptible at the glider end. And can you prove that your mega expensive superwinches will do any better in rough conditions with a wobbly student pilot at the controls of the glider? Derek Copeland |
