Im running through typical interview questions at moment and seem to be getting bit confused by this one..
Does vmca and vmcg vary with aircraft weight ??
If asked this question in an interview my answer would be yes it does vary with weight ...
due to the fact that an increase or decrease in weight changes the centre of gravity which in turn depending on the cg position of that weight,changes the vmcg/a speeds.
example being an aft cg requires a higher vmcg/a because of the shorter moment arm meaning less effectiveness on the rudder, so the aircraft will have to increase its speed to allow directional control...!!
is this answer correct as the more i read up on this question i seem to be getting that little bit confused with conflicting info..
can anyone shed any light on this or is my answer ok..!??
Thanks for any help given....
