VG's do lower your stall speed. I have them i know. but if I may make an analogy? It's <br />like <br />flooring your car 100 feet from a yellow light then getting Nitros and trying to make the <br />yellow light from a block away. always make a good approach and watch your speed and <br />bank angle. it's ok to go around.

I am not sure that speed, as an absolute, should be the real question in this debate. Personally I can't see how it matters a jot whether you stall at 42 knots or 36 knots, if you don't maintain enough margin over the stall speed you are putting yourself at risk.<br /><br />What is important is the behaviour of the aircraft at the stall. In the sixties when Piper and Cessna were trying to build a 'Plane for every garage' they recognised the bad PR form the stall/spin accidents and tried to build the 'stall proof' aircraft. Colts and 150s were their answer and Colts, which I learned on, were very stall resistant indeed. Unfortunately they were also slow and soggy. These days the focus seems to be more on efficiency, eg, the Cirrus and other plastic fantastics.<br /><br />Unfortunately comparing the behaviour of aircraft with and without VGs is difficult. While they may lower stall speed somewhat for all aircraft how they affect the actual stall on different aircraft may be different. If we could be sure they made all aircraft stall straight ahead with no wing drop then we'd have a result, however if your particular aircraft always stalled that way, or nearly so then it is more difficult to suggest that it would be beneficial on all.<br /><br />Does anyone have any definitive figures on how they affect cruise speed at particular engine settings?<br /><br />Almost as many questions as answers.

Luis, SSS stands for the Superfluous Seaplane Site. Or Serious Seaplane Sightings. Or Serious Seaplane Sighs. Something like that. Frankly, I wish it would go away--but look for an invitation in your email.
