The problem is thus: We are taught a 'safe' approach speed - it's normally a bit more than 1.3 Vso, for 'safety'. Then we add a bit for the wind, a bit for the gust, and a bit for mother/wife/kids, uncle tom cobley and all.

Another factor usually forgotten is that your 'book' stall speeds are based on max gross weight. They reduce as you reduce the a/c weight, so your landing speeds should reduce accordingly.

You finish up with a bunch of people dragging something like a PA28 over the hedge at 75 kts with full flap (and I know people who go faster). There lies the road to broken nosewheels as well as holes in the hedge.

Frankly we're taught so much to fear the stall, I believe there's far more of a danger of people going off the far end than stalling in - how many accident reports have you seen recently where someone with a functioning engine come up short? You've also got a pretty good AOA indicator in the cockpit of every plane I've ever flown.. here's a clue.. it's right in your hand

P.S. I'm a weekend warrior too...
