badhi · Answer

oh i think they have given the "total acceleration" which consist of the acceleration towards the center (maybe from air pressure or something) + accleration of the plane by itself.

from radius of curvature you can find the perpendicular component . since

total acceleration vector = perpendicular acceleraton component + acceleration vector of  generated by the plane

you can find the acceleration vector generated by the plane from that

firekat97 · Answer

so the perpendicular component is the acceleration toward the centre?

badhi · Answer

I guess so. That can be obtained with the radius of curvature

firekat97 · Answer

ummm okay thanks, but how would we know to include the acceleration toward the centre?
