Work Step by Step

(a) We know that the pilot measures the correct proper time of the cockpit clock as he is in the rest frame with respect to the clock. (b) You measure the correct proper time in the large clock on the control tower because you are in the rest frame w.r.t to the clock on the control tower. (c) As pilot is in the rest frame w.r.t to the airplane, he measures the correct proper length of the airplane. (d) Now you are in the rest frame w.r.t the runway, so you measure the correct proper length of the runway.
