<P class=MsoNormal>A full scale friend lent me a book by Alan Cassidy

speed to enter snap divided by the Power ON stall speed -
Squared.<BR><BR><BR><BR>His example (Pits S2A) was 105/55 =1.909
(1.909)2 =3.64 Gs. This means you would try to have
an instantaneous 3.64 G loading if entering the “flick roll” at 105
mph.<BR><BR><BR><BR>What I find fascinating about the formula is the “power

mathematically we cannot do a snap. Or the instantaneous Gs required
