leans

An illusion in which the pilot perceives the aircraft to be tilted, leading him or her to lean the aircraft in the opposite direction to balance it. The pilot is unable to perceive changes along the lateral axis of the aircraft. If an aircraft is banked to any one side at a rate lower than 2°/s and the pilot does not refer to the instruments (and other outside visual clues are absent), he or she may not perceive this change and may believe that the aircraft is still flying with the wings level. If the wings are then leveled, the pilot will feel that the aircraft is banked in the reverse direction and may tend to bank (lean) it to the original side.

References in classic literature ?

cried the lean Friar, fairly gnashing his teeth with rage.

Down slipped the fat Brother from off his horse on one side, and down slipped the lean Brother on the other.

Send some money straightway to these poor folk, lest the fat one waste away and grow as lean as the lean one, and the lean one waste away to nothing at all, ere they get to Lincoln Town; but send them only ten shillings apiece, lest they grow puffed up with pride, Any more than that that thou sendest, send to me.

So he went first to the lean Friar, and, thrusting his hand into the pouch, he drew forth a leathern bag and counted therefrom one hundred and ten pounds of golden money.
