The trick to flying the Chinook is learning how small it is.
In time...some folks can get the "feel" for where the Cargo Hook is and how high off the ground the aft gear are....but it is a rare pilot that can also "feel" where the Aft Gear is.
When it came to putting the Aft Gear down on a Rice Paddy Dike....that took some doing. Putting the Cargo Hook into the Hook Up guy's hands was no mean trick but even some never got it figured out.
Pitch Attitude and knowing which particular Pitch attitude was needed or what Cyclic Stick Position was needed when doing maneuvers with the aft gear or sometimes forward gear in contact with the ground took some getting used to as once the gear were on the ground....two inches of aft cyclic glued the gear and then all pitch attitude control was done by use of the Thrust Lever (Collective Lever).
