Thank you very much for producing the Cessna Pamphlet which is extremely interesting.
Your said:
"Cessna produced a pamphlet in the late 1970’s that expanded on the spin for all Cessna SEP’s by model. For all models the first 180 deg of rotation was considered the spin entry and a normal stall recovery ( ie start with pushing wheel forward) could be used. Only after 2 full turns is the spin considered fully developed and the POH spin recovery method should be used."
The pamphlet did not say anything of the kind. Below is word for word copied and pasted from the pamphlet:
During this incipient phase, spin recoveries in those airplanes approved for intentional spins are usually rapid, and, in some airplanes, may occur merely by relaxing the pro-spin rudder and elevator deflections. However, positive spin recovery control inputs should be used regardless of the phase of the spin during which recovery is initiated. Briefly, these control inputs should be 1) neutral ailerons and power off, 2) full rudder opposite to the direction of rotation, 3) just after the rudder reaches the stop, elevator briskly forward to break the stall, and 4) as rotation stops, neutralize the controls and recover from the resulting dive. Using these procedures, recoveries are typically accomplished in from 1/8 to 1/2 turn during the incipient phase.
