One of our more experienced FIs dug through the POH and revised the SOP speeds. Pilots were firmly re-briefed and landings improved greatly.
Without wanting to appear at all accusatory, what could be the need for any organization operating certified aircraft for which there is an approved POH to have "SOP speeds"? Why would an SOP be anything other than "fly the POH speeds"? Surely the organization could not think itself more competent than the aircraft manufacturer in producing operating information for the type!?
