I've done stalls in a 737-300 during flight test at Boeing, = and it's tame. =20 Furthermore, airliners and certainly the Legacy are designed to go slow = as well as fast, through the use of slotted flaps (and, on airliners, = leading edge slats). It's no coincidence that the stall speed of a = Legacy is 59kt, Greg Cole went to some trouble to design those = beautiful, highly effective slotted, cambered flaps and we pay a cruise = speed penalty for those big ugly flap hinge brackets. But with stall = speed below 70kt, you can run your instrument approach at 90kt and use = the lowest minimums (Cat A) on the chart. What gives, guys? Forget the inadvertant stall and let's suppose your = engine quits over rocky or forested terrain. The best available open = area is too short but every knot you can peel off your approach speed = increases your chance of survival. Knowing and trusting your plane down = to Vstall could easily save your life.
