Good Morning,
please excuse my ignorance, but I seem to be seeing discrepancies within the Cessna 150 climb speeds. The 1968 POH says that 57MPH is the best angle of climb speed, whereas the 1969 POH says that 64MPH is the best angle of climb speed, is there really any difference or is it just the newer POHs were more accurate as I don't believe there are any significant differences between the 1968 and 1969 Cessna 150s that would cause this.

Are the later figures used as a safety margin against the stall speed?
Or am I just being extremely pedantic? :roll:

No that is a good question, which has already been posed in Technical Discussion.

This is probably the better part of the forum, maybe one of the mods can move the other thread in here and close this one.

I understand that the cause may be knot-mph conversion discrepancies between the 1968 and 1969 pohs, however the 1967 poh says 52mph, which is again fairly different. I think they mean 52 knots ≈ 60Mph
