    What is the minimum engagement height for AP use?

    • 350 ft

    • 400 ft

    • 450 ft

    • 500 ft

    Correct Answer
    A. 400 ft
    Explanation
    The minimum engagement height for AP use is 400 ft. This means that the aircraft must be at least 400 ft above ground level in order to engage the AP (Autopilot) system. This height requirement ensures that the aircraft is at a safe altitude before the autopilot takes control of the aircraft's navigation and flight controls.

    What is the lowest altitude that you can disengagement the AP?

    • 40 ft

    • 80 ft

    • 60 ft

    • 50 ft

    Correct Answer
    A. 50 ft
    Explanation
    The correct answer is 50 ft. This means that the autopilot (AP) can be disengaged when the aircraft reaches an altitude of 50 ft or lower. This altitude is likely chosen to ensure that the aircraft is close to the ground and in a stable position before the pilot takes full control of the aircraft. It is important for the pilot to have control at this low altitude to ensure a safe landing or maneuvering.

    What is the Max RWY slope deviation?

    • -2% / +2%

    • -1,8% / +2%

    • -2% / +1,8%

    • -2% / + 2,1%

    Correct Answer
    A. -2% / +2%
    Explanation
    The maximum runway (RWY) slope deviation is between -2% and +2%. This means that the runway slope can vary within this range without exceeding the acceptable limits. A slope of -2% indicates a downward gradient, while +2% indicates an upward gradient. It is crucial to maintain the runway within these limits to ensure safe takeoffs and landings for aircraft.

    What is the Max altitude that the APU can provide bleed air for Airco?

    • 33000 ft

    • 21000 ft

    • 30000 ft

    • 15000 ft

    Correct Answer
    A. 15000 ft
    Explanation
    The APU (Auxiliary Power Unit) is a device that provides power to the aircraft when the main engines are not running. In addition to power, the APU also supplies bleed air, which is used for various purposes including air conditioning and pressurization. The maximum altitude at which the APU can provide bleed air for air conditioning is 15,000 ft. This means that above this altitude, the APU will not be able to supply bleed air and other sources of air conditioning and pressurization must be used.

    Rate this question:

    What is the Max altitude to start the APU?

    • 30000 ft

    • 33000 ft

    • 41000 ft

    • 25000 ft

    Correct Answer
    A. 30000 ft
    Explanation
    The maximum altitude to start the APU is 30000 ft. This means that the APU (Auxiliary Power Unit) should be started before the aircraft reaches an altitude of 30000 ft. Starting the APU at higher altitudes may not be possible or may cause issues due to the reduced air density and lower oxygen levels at higher altitudes. Therefore, it is important to start the APU at a lower altitude to ensure its proper functioning during the flight.

    Correct Answer
    A. 33000 ft
    Explanation
    The APU (Auxiliary Power Unit) is a device in an aircraft that provides electrical power when the main engines are not running. The question is asking about the maximum altitude at which the APU can provide electrical power. The correct answer is 33000 ft. This means that the APU can supply electrical power up to an altitude of 33000 ft.

    What is the Maximum Altitude For Flap Extension?

    • 41000ft

    • 21000ft

    • 20000ft

    • 15000ft

    Correct Answer
    A. 20000ft
    Explanation
    The maximum altitude for flap extension is 20000ft. Flaps are aerodynamic devices on the wings of an aircraft that help increase lift and drag during takeoff and landing. They are typically used at lower speeds and altitudes to improve the aircraft's performance. However, at higher altitudes, the air density decreases, which affects the effectiveness of the flaps. Therefore, it is not recommended to extend flaps beyond 20000ft as they may not provide the desired lift and could potentially compromise the safety and stability of the aircraft.

    • - 0,2 PSI

    • - 0,1 PSI

    • - 0,6 PSI

    Correct Answer
    A. - 0,5 PSI
    Explanation
    The maximum negative pressure is -0.5 PSI. Negative pressure refers to a pressure that is lower than the surrounding atmospheric pressure. In this case, the maximum negative pressure is 0.5 PSI below atmospheric pressure. This means that the pressure inside the system or container is 0.5 PSI lower than the pressure outside.

    • 0,4 PSI

    Correct Answer
    A. 0,2 PSI
    Explanation
    During takeoff and landing, the aircraft experiences changes in air pressure. The question asks for the maximum negative pressure, which refers to the lowest pressure experienced by the aircraft during these phases. Among the given options, 0.2 PSI is the lowest value, indicating the maximum negative pressure during takeoff and landing.

    During inflight start the Max ITT Temp is?

    • 740°C

    • 815°C

    • 875°C

    • 990°C

    Correct Answer
    A. 815°C
    Explanation
    During inflight start, the maximum allowable ITT (Interstage Turbine Temperature) is 815°C. This temperature limit is set to ensure the safety and optimal performance of the aircraft's engine. Exceeding this temperature could lead to engine damage or failure. Therefore, it is crucial for pilots to closely monitor the ITT during inflight start procedures to ensure it stays within the specified limit.

    What are the MIN / MAX N2 ratings? (CF34-8E5)

    • 58,4% / 99,4%

    • 58,5% / 99,5%

    • 58,5% / 99,4%

    • 58,4% / 99,5%

    Correct Answer
    A. 58,5% / 99,4%
    Explanation
    The MIN/N2 rating refers to the minimum and maximum rotational speed of the N2 compressor section of the CF34-8E5 engine. The correct answer is 58,5% / 99,4%, indicating that the N2 compressor can operate at a minimum rotational speed of 58.5% and a maximum rotational speed of 99.4%. This range ensures optimal performance and efficiency of the engine during different operating conditions.

    In the event of hydraulic system overheat (fluid temperature above ______), the HYD 1 OVERHEAT EICAS warning message will be displayed. In this case, the SOV can be manually commanded through a guarded pushbutton on the hydraulic system control panel.

    • 100°C

    • 125°C

    • 145°C

    Correct Answer
    A. 145°C
    Explanation
    In the event of hydraulic system overheat, the HYD 1 OVERHEAT EICAS warning message will be displayed. The correct answer is 145°C. When the fluid temperature exceeds this temperature, the warning message will be triggered. To address the issue, the SOV (Shut-Off Valve) can be manually commanded through a guarded pushbutton on the hydraulic system control panel.

    If you are flying N-1 at V2+10kt, what is the max bank angle?

    • 20°

    • 15°

    • 25°

    • 17°

    Correct Answer
    A. 25°
    Explanation
    When flying at V2+10kt, the maximum bank angle is 25°. Bank angle refers to the angle at which an aircraft is tilted or banked while turning. It is important to maintain a proper bank angle during turns to ensure stability and prevent excessive strain on the aircraft. In this scenario, the maximum bank angle of 25° is necessary to maintain control and stability while flying at V2+10kt.

    When AUTO MODE is in use during TO/GA when N-1 or Windshear the Max ITT Temp in the first 2 MIN?

    • 965°C

    • 949°C

    • 1006°C

    • 990°C

    Correct Answer
    A. 1006°C
    Explanation
    During AUTO MODE, when TO/GA (Takeoff/Go-around) is engaged and there is an N-1 (engine failure) or a Windshear condition, the maximum ITT (Interstage Turbine Temperature) in the first 2 minutes is 1006°C.

    What is the Max over pressure?

    • 8,3 PSI

    • 8,4 PSI

    • 8,6 PSI

    • 8,7 PSI

    Correct Answer
    A. 8,6 PSI
    Explanation
    The correct answer is 8.6 PSI. The question is asking for the maximum over pressure, which refers to the highest pressure above atmospheric pressure. Out of the given options, 8.6 PSI is the highest value, indicating the maximum over pressure.

    When the hydraulic fluid temperature increases to _______, the HYD 1 HI TEMP EICAS caution message will be displayed.

    • 100°C

    • 125°C

    • 145°C

    Correct Answer
    A. 100°C
    Explanation
    When the hydraulic fluid temperature increases to 100°C, the HYD 1 HI TEMP EICAS caution message will be displayed.
