Thanx
misd-agin, that was a quick reply
Effectively the doc states 80lbs for the 320 (though the report is for the 300, other types are listed on page 14).
I'm still not sure of the value though, as
the 80lbs are at V1, 135kts in this case.
Using your googling idea also returned a document from Ural Airlines with an FCOM Bulletin now showing even less force required, e.g. 30daN = 67lbs on a diagram. Just spent some time perusing my 320 FCOMs for it, but nope...
Anybody with an A320 (or other "official") reference as to the force to be used during the preflight (usually during taxi) control check?
