1How does the speed of sound in the atmosphere vary with changes in altitude in the troposphere?

A.Decreases with increasing altitude due strictly to decreasing static temperature

B.Increases with increasing altitude due to decreasing air density

C.Remains constant because pressure and density decrease proportionally

D.Decreases with altitude primarily due to decreasing static pressure

Explanation: The speed of sound in a perfect gas depends solely on absolute static temperature (a = sqrt(gamma * R * T)). In the standard troposphere, ambient temperature decreases with altitude, which causes the speed of sound to decrease.

2Which of the following correctly defines the flight Mach Number (M)?

A.The ratio of true airspeed (TAS) to the local speed of sound (a)

B.The ratio of indicated airspeed (IAS) to equivalent airspeed (EAS)

C.The ratio of calibrated airspeed (CAS) to local speed of sound

D.The ratio of dynamic pressure to static pressure at sea level

Explanation: Flight Mach number is defined as the ratio of the aircraft's true airspeed (TAS) to the speed of sound (a) in the local ambient atmosphere (M = TAS / a).

3What is the definition of Critical Mach Number (Mcrit)?

A.The freestream Mach number at which airflow over any part of the aircraft first reaches Mach 1.0

B.The freestream Mach number at which the entire aircraft experiences supersonic flow

C.The maximum operating Mach number (MMO) structural limit

D.The Mach number at which total aircraft drag reaches its minimum value

Explanation: Critical Mach Number (Mcrit) is the free-stream Mach number at which local airflow over the surface of the aircraft (typically the upper wing surface) first reaches sonic velocity (Mach 1.0).

4What is the primary aerodynamic advantage of sweeping aircraft wings back for high-speed jet transport aircraft?

A.It increases the Critical Mach Number (Mcrit) by reducing the airflow velocity component normal to the leading edge

B.It increases maximum lift coefficient (CLmax) at low speeds

C.It eliminates spanwise airflow and wingtip stall tendencies

D.It decreases structural weight and wing torsional loads

Explanation: Wing sweep delays compressibility effects by reducing the component of airflow velocity perpendicular to the wing leading edge (V_normal = V_freestream * cos(sweep angle)), thereby increasing Mcrit.

5In heavy jet performance, what is the definition of V1?

A.Takeoff decision speed: the maximum speed at which the pilot must take first action to reject the takeoff, and the minimum speed to continue after critical engine failure

B.The minimum speed at which the aircraft can become airborne with one engine inoperative

C.The rotation speed at which backpressure is applied to initiate pitch attitude increase

D.The final takeoff climb speed achieved at 1,500 feet above airfield elevation

Explanation: V1 is the takeoff decision speed. If a critical engine fails before V1, the takeoff must be rejected; if an engine fails at or after V1, the takeoff must be continued.

6What is the operational definition of Rotation Speed (Vr)?

A.The speed at which pitch rotation is initiated to achieve the target takeoff climb pitch attitude

B.The speed at which the main landing gear leaves the runway surface

C.The speed achieved at the screen height of 35 feet above the takeoff surface

D.The minimum speed for directional control on the ground with an engine inoperative

Explanation: Vr is the rotation speed at which the pilot initiates control stick/yoke backpressure to rotate the aircraft pitch attitude to reach V2 by the screen height.

7What is the definition of V2 speed for a transport category jet?

A.Takeoff safety speed to be attained by the 35 ft screen height with one engine inoperative

B.Maximum speed for landing gear retraction following liftoff

C.Minimum speed at which the aircraft can safely fly in the en-route clean configuration

D.Decision speed for initiating reverse thrust during a rejected takeoff

Explanation: V2 is the target takeoff safety speed that must be attained by the screen height (35 feet dry / 15 feet wet) and maintained during the second segment climb following an engine failure.

8What is Take-off Run Available (TORA)?

A.The length of runway declared available and suitable for the ground run of an aeroplane taking off

B.The total distance from brake release to reaching 35 ft screen height

C.The length of runway plus stopway length

D.The length of runway plus clearway length

Explanation: TORA is the declared length of runway suitable for the ground roll of an aircraft during takeoff.

9How is Take-off Distance Available (TODA) calculated?

A.TORA plus Clearway length

B.TORA plus Stopway length

C.TORA minus clearway length

D.TORA plus Stopway plus Clearway

Explanation: TODA is defined as Take-off Run Available (TORA) plus the length of any clearway available (TODA = TORA + Clearway).

10How is Accelerate-Stop Distance Available (ASDA) defined?

A.TORA plus Stopway length

B.TORA plus Clearway length

C.TODA plus Stopway length

D.Length of runway suitable for landing roll

Explanation: ASDA is Take-off Run Available (TORA) plus the length of any declared stopway (ASDA = TORA + Stopway).
