Message: [QUOTE="Cardinal, post: 5266, member: 40"] There is a chart plotting bank angle against load factor against stall speed increase. I think its in the old Flight Training Handbook, Ch 17, but I don't have one and they're getting hard to find. The Gleim CFI book has it reprinted. You are on the right track, load factor is the inverse cosine of the bank angle. ( 1/Cos60 ) Modest bank angles, as you well know, generate very small increase in load factor, but at 60 degrees it starts to get serious 45 degrees = 1.4 Gs, 1.20 x Vs 60 degrees = 2.0 Gs. 1.40 x Vs 75 degrees = 4.0 Gs, 2.00 x Vs Much beyond that and the the values go off the chart. I think Garrison has written on this subject several times, but not very recently. He is an aerodynamic and literary god among men, IMHO. [/QUOTE]
