Having taught and seen the "Jacobson Flare" in action, I recall a friend asking a instructor at one of the major IFR training schools if they taught the "Jacobson Flare". The reply.... "Nope, we just land".... that about sums it up. Jacobson relies on flying a constant angle final approach to a nominated aiming point with a stable path descent. Jacobson clearly states to hold the aiming point constant on finals using a "cut off angle" as the determining factor for the flare. A supposed glideslope for VFR pilots.... That's about all I can remember, like Ace, I'll see if I can dig up some further info.
