The pilot is requested to increase speed to 250 kt by the ATC. The new CL is... Options: A. 0.47 B. 0.38 C. 0.2 D. 0.40 Answer: B Explanation: The lift coefficient (CL) is directly proportional to the airspeed of the aeroplane. Therefore, when the pilot increases the airspeed from 200 kt to 250 kt, the new CL decreases accordingly. In this case, with the new airspeed of 250 kt, the new CL is calculated to be 0.38. Question 2 For a twin-engine aeroplane, a reason for limiting a propeller's diameter is to... Options: A. avoid excessive propeller-tip velocities at high RPMs. B. increase ground clearance. Abilitazioni Abilitazioni Quiz ATPL (A) Principles of Flight PDF https://www.easy-quizzz.com/it/ C. avoid a reduction in power absorption. D. reduce the aeroplane's minimum control speed. Answer: A Explanation: Limiting a propeller's diameter for a twin-engine aeroplane is necessary to avoid excessive propeller-tip velocities at high RPMs. Question 3 An aeroplane has a stall speed of 100 kt. When the aeroplane is flying a level co-ordinated turn with a load factor of 1.5, the aeroplane will stall in this turn at: Options: A. 150 kt. B. 122 kt. C. 82 kt. D. 141 kt. Answer: B Explanation: In a level co-ordinated turn with a load factor of 1.5, the stall speed will increase by the square root of the load factor. Therefore, the aeroplane will stall in this turn at approximately 122 kt. Question 4 The speed VC in gust diagram... Options: A. equals 55 ft/s. B. equals 50 ft/s. C. equals 25 ft/s. D. equals 66 ft/s. Answer: B Explanation: In a gust diagram, the speed VC represents the minimum speed required to maintain level flight in turbulent conditions.

IAS increases. B. TAS decreases. C. lift coefficient increases. D. lift coefficient decreases. Answer: C Explanation: When climbing above the tropopause at constant Mach number and aeroplane mass, the lift coefficient increases due to the reduction in air density which requires higher lift to maintain level flight. Question 6 After suspecting a fuel leak, the aircrew flying a jet transport aircraft decides to divert to the nearest suitable airport. At what speed should they fly? Options: A. Maximum Range Speed B. Maximum Endurance Speed C. MMO D. Long Range Speed Answer: A Explanation: The aircrew should fly at Maximum Range Speed when diverting to the nearest suitable airport after suspecting a fuel leak in a jet transport aircraft. Question 7 Outboard ailerons are (1) at (2) speeds, to prevent (3) Options: A. (1) locked; (2) high; (3) aileron reversal. B. (1) locked; (2) low; (3) aileron reversal. Abilitazioni Abilitazioni Quiz ATPL (A) Principles of Flight PDF https://www.easy-quizzz.com/it/ C. (1) unlocked; (2) high; (3) aeroelastic phenomena. D. (1) unlocked; (2) low; (3) aeroelastic phenomena Answer: A Explanation: Outboard ailerons are locked at high speeds, to prevent aileron reversal. Question 8 Dihedral contributes positively to lateral stability by: Options: A. Increasing lift on the wing away from the wind. B. Increasing drag on the wing away from the wind. C. Increasing the lift on the wing into the wind. D. Increasing drag on the wing into the wind. Answer: C Explanation: Dihedral contributes positively to lateral stability by increasing the lift on the wing into the wind. Question 9 Refer to figure. What does line 3 represent? Options: A. Induced drag B. Parasite drag C. Total drag D. Profile drag Answer: A Explanation: Question 10 In twin engine aeroplanes with propellers turning clockwise as seen from behind: Options: Abilitazioni Abilitazioni Quiz ATPL (A) Principles of Flight PDF https://www.easy-quizzz.com/it/ A. the left engine is the critical engine. B. the ‘minimum control speed’ is determined by the failure of the right engine. C. the left engine produces a higher yaw moment if the right engine fails than vice versa. D. the right engine is the critical engine. Answer: A Explanation: In twin engine aeroplanes with propellers turning clockwise as seen from behind, the left engine is considered the critical engine because it produces more yawing moment in the event of an engine failure.
