A large airliner cruises at a velocity of 250 m/s. Assuming that the aircraft maintains the same speed and altitude whilst flying at a roll angle of 25 degrees to perform a circular turn, write down expressions for the following... a) The resultant force the aircraft produces in order to turn in terms of its weight and roll angle. b) The sideways force required for the turn in terms of the aircraft weight and roll angle. c) The centripetal acceleration required to make the turn in terms of roll angle. d) The radius of the turn performed in terms of flight velocity and roll angle. Hence, calculate this radius
