Quoting stall speeds with VG's
Was wondering if the wealth of PPrune knowledge would know this.
Let's say an aircraft's stall speed is 50 knots and with Vortex Generators fitted, it becomes 45 knots.
Does this mean that the POH would be modified (in theory) to say 45 knots stall, or are stall speeds identified by a seperate line item in the POH?
From memory as an example I think I heard someone saying a while abck that a Chieftain stall speed varied depending on whether or not VG's are fitted so that made me think there might be an extra line item. I guess I'm wondering if the new stall speed with VG's actually REPLACES the stall speed without them...........?
