Big Pistons Forever
From your quote of the Cessna pamphlet it makes no sense to me for the following reasons; the PA28-140 Service bulletin 753, Dec 1982 gives a height loss of 1,000 ft for one spin, Cessna 152/172 manuals also give 1,000 ft loss for the first rotation, Robin 2160 suggests 1300 ft should be allowed for a full recovery from the first rotation.
The above figures are given for the published POH spin recovery technique. In most of the light aircraft POH the standard spin recovery carried out for type approval is used although sometimes badly written and vague using terms: "briskly", "pause" etc. The original Slingsby manuals did state that the hand control should be moved forward and centralised but following a number of fatalities this was later amended adding "...even if the stick requires moving fully forward to its limit".
