Now that it seems we have gotten Nick's attention back on this board ( good to see you back) I would like to ask you once again to explain the relation ship between the tail rotor disk and the fin area. I say once again as you explained this to me once over the phone, but I want be sure of the numbers.
For the record, I was asking Nick about the size of the tail fin and its effect on keeping the a/c sort of going in the right direction in a tail rotor failure. Nick explained a glaring difference that I had not considered. Tail rotor DRIVE failure (tail rotor stopped) and fixed pitch failure.
Nick, can I ask you to explain again, I seem to remember a number of 1.3 times the area.........
