Hasn't anybody told you lot!!
Bah! Humbug!!
The FOs job on the 209 is to occupy the rear most seat, which is a little vertically adjustable arrangement and, with his feet thru the horizontally cut / vertically aligned hatch, use same to keep tail from dragging on ground until full elevator authority is achieved.
He/she then works his /her way fo'rad, to assist in fwd c of g movement, and to exercise complete control over the dual thronomisters which can be operated only from the RH seat due to pilot workload, P - factor, and torque.
It works in the reverse sense on landing.......
Its in the POH!!! Honestly!!
