Control column flailing during the flare - a dangerous practice by some pilots.
Frantic "see-sawing" of the control column, otherwise technically known as gross over-controlling, is a common characteristic seen both during simulator and line operations. Often the habit is ingrained from ab-initio days. Although it may or not result in a smooth touchdown, this rather distasteful technique invariably uses up extra runway which in turn is usually countered by heavy manual braking and passenger discomfort.
It appears not to be a deliberate landing technique, but rather an unconscious "twitch" factor habit where the pilot is feeling for the runway in the hope of making a smooth touch down. Interestingly, it often does seem to work on most occasions; thereby reinforcing the pilots belief that it is the best way to achieve a smooth landing. The usual ensuing float before final touchdown may also be a factor in over-runs, although this is never mentioned as a contributory cause in accident reports.
For any PM, it is a wise precaution to keep valuable bits of his/her anatomy well clear of the control column full aft movement when their compatriot is feeling for the deck in such a manner, as well as knees well spread to avoid being speared by the excessive lateral lashing of the control wheel. That danger to boobs, balls or knees fortunately does not exist with a side stick controller which may be a factor in the good safety record of the Airbus series of airliners.
Have any other Pprune readers witnessed at first this hand appalling landing technique by some pilots, which is quite distressing to those of us who consider a beautifully executed smooth and gentle flare and touch down on the right spot on the runway, an event of consummate skill?
