Dane Meyer was interested in the strain imposed on a canopy in a downplane configuration. Although I haven't got any figures - my impression is that the canopy loads are much higher than straight and level. The canopy shudders and the lines moan when you're really motoring. I'm not at all concerned about a canopy failure though. After all, it has already been loaded to 5 G's or so in slowing me from terminal. Also, the load factor is limited by the strength in your leg grips. I'm not exactly sure how low I've gone with a downplane but its probably not under 300 feet. I've always got enough altitude to turn into wind and land without hooking it. Also, I don't want to have high airspeed from the outswing in case there's some turbulence in the landing area. Breakoff is determined by whoever goes first. It's often determined by closeness to the landing area. Don't think of taking a downplane under a grand unless you you can accurately "eyeball" your altitude. It's important to have objects on the ground as visual clues. The altimeter is too distracting and innacurate. -- Made in New Zealand --> Brent Callaghan AT&T Information Systems, Lincroft, NJ {ihnp4|mtuxo|pegasus}!poseidon!brent (201) 576-3475
