AOPA magazine called Australian Pilot (August-September 2014) has an article called Short Field Landings. The author is Bill Grieve of Aeroskill Ultralight Flight Training Centre, Caboolture. He recommends pilots should first learn to fly slow at an altitude where "mistakes don't hurt." He then writes:
"If a wing starts to drop, pick it up with opposite rudder using secondary effect of roll. If the aircraft starts to yaw, correct it with sharp punches on the rudder to yaw the aircraft without inducing roll. Remember you are flying near the stall - if a wing drops and you try to pick it up with aileron, the down-going aileron on the dropped wing causes that wing to exceed critical angle of attack and the wing will drop further sometimes violently."
He continues: "For a short field landing you are now dragging the aircraft in with power- remember that once you are set up on final, with wings level and at the correct speed, the stick is not moved sideways. Use rudder to pick up a dropped wing. To overcome the angle of descent/rate of descent problems associated with slow flight in short-field landings, use power to drag the aircraft in much flatter. I'm sure there are many other techniques used to achieve the same result but this is the one I use and teach."
Presumably as Bill Grieve is an experienced instructor at an Ultralight flying school, he article is aimed at Ultralight pilots. It may go some way to explain why pilots flying ultralights have a higher accident rate than standard general aviation pilots flying Cessnas, Warriors and similar everyday flying school aeroplanes.
It seems extraordinary that Bill Grieve would continue to perpetuate the hoary old myth of picking a wing up with rudder when close to the stall. More alarming is his advice to students to "correct yaw with sharp punches on the rudder without inducing roll.::eek:
Is the short field technique he advocates common to only ultralight types? My understanding of Light Sports Aircraft is they are designed to stall benignly and part of the design includes the ailerons are effective below stall speed. As for "dragging" in to land with power to make the approach flatter, the situation becomes fraught with danger if for some reason the engine falters (according to some reports, happens in ultralights more often than standard aeroplanes)
It is good that that AOPA encourages people to send articles for publication, but maybe there is a need to vet these articles for technical integrity before publication.
