Final manoeuvre
Oh! Here’s another reference to the manoeuvre to be going on with:
From
Select Committee on Chinook ZD 576
Supplementary memoranda following October Hearings
Question 590
Captain Hadlow said that he considered that the position in which the rudder was found by the Air Accidents Investigation Branch (a 77 degree left pedal 1.7 inches forward) was a last ditch effort to turn the aircraft.
Small yaw pedal inputs are used with cyclic to maintain balanced flight when performing a turn at low speeds but at higher forward speeds little or no yaw input is required to turn the aircraft. But large yaw pedal inputs are made, with cyclic and collective, during "hover" turns and when also performing "fast stops". This technique uses all the flying control inputs to turn the aircraft into a sideways position whilst in forward flight, in order to use its large surface area to act as an air brake and assist in the rapid reduction of speed.
