You're not of course, because you'll be too slow and, unless you reacted IMMEDIATELY and got the stick far enough forward for a zero G push-over you'll be below stall speed, from where any turn will spin immediately. The rule of thumb[*] is to push over until your dive attitude is as steep as you were going up and then hold the attitude without attempting to turn until you've reached the landing approach speed you'd chosen for the day. Then, and only then you decide whether you've space to land ahead or whether you need to turn. Yes, I agree with this, except there's no need to push. Simply keeping the stick roughly in the middle will allow the nose to fall through as the speed drops, without any danger of stalling, and with the wing operating at an efficient (low drag) angle of attack. Easing the stick forward enough to get zero G is OK too, but unnecessary. Negative G is likely to be counterproductive and actually cause more drag and therefore bleed off more energy than a small amount of positive G. [*] unless, of course, its a low break where you'd become a lawn dart if you used the above technique. Off a winch you'll always have plenty of specs ahead, so a shallower recovery attitude is OK once you're comfortable above stall speed and anyway you won't need to turn. I don't agree. Assuming you maintain a low drag angle of attack, you'll arrive back at the release height with the same speed you had on the way up. We know you made the pull up into the climb from just above ground level, with an adequate safely margin from stalling, and with lower speed than you had in the climb. There's no reason at all that you can't safely pull out of the dive, starting from the cable break height, even if the cable broke just as you were entering full climb. |
