Two identical aeroplanes A and B, with the same mass, are flying steady level co-ordinated 20 degree bank turns. If the TAS of A is 130 kt and the TAS of B is 200 kt:
Possible answers:
the turn radius of A is greater than that of B.
the load factor of A is greater than that of B.
the rate of turn of A is greater that of B. (correct)
the lift coefficient of A is less thant that of B.
Is it, just theoretically, possible, that the last question could be also correct, since the question doesn´t state anything about same aircraft configuration (flaps/spoilers) or same air density?
Identical aeroplanes with same mass and same AOB suggests that they are both producing the same amount of lift.
Lift = CL 1/2Rho TAS squared
Aircraft A is flying at a lower TAS, so to generate the same lift as aircraft B with the same air density it would require a greater CL. This is not an option in the question.
It would be possible for aircraft A to generate the same lift with a lower CL than aircraft B, but to achieve this it would need a value of Rho that was greater than that for aircraft B. Nothing in the questions suggests that this is the case, so option D is unlikely to be the correct answer. You would be unwise to select this option in the exam.
But there is certainly enough information to indicate that option C is the correct answer.
