14. An all moving tailplane is used in preference to elevators on high speed aircraft: because the effect of the elevator is reversed above the critical Mach number. because shock wave formation on the elevator causes excessive stick forces. a. b because shock wave formation ahead of the elevator causes separation and loss of elevator effectiveness. C. d. because it would be physically impossible for a pilot to control the aircraft in pitch with a conventional tailplane and elevator configuration. 15. Mach Trim is a device which: moves the centre of gravity to maintain stable lateral stick forces in the transonic region. automatically compensates for pitch changes while flying in the transonic speed region. prevents the aircraft from exceeding its critical Mach number. a. b. C. d. switches out the trim control to prevent damage in the transonic region. 16. What is the moement of the centre of pressure when the wing tips of a sweptwing aeroplane are shock stalled first? a. Outward and forward. b с. d. Inward and aft. Outward and aft. Inward and forward.
