play with all the airspeeds and it hardly makes any difference to your rate of descent. Vertical velocity is only around 20 knots anyway at 2000ft per minute - that aint gonna kill you - the tree coming through the perspex will though !!
Playing with the airspeed in auto will give you a staggering rate of accuracy in selecting your touch down point - as long as you get enough back on for flare time of course !
