Question 1: How does the Mach number affect the design of control surfaces on a high-speed aircraft?

Which action should you take?

Choose only one option

It increases the load on the ailerons due to higher wing loading

It affects the thickness of the control surfaces to avoid shockwave interference

It requires the control surfaces to be larger to handle higher aerodynamic forces

It reduces the effectiveness of the control surfaces at transonic speeds

Question 2: What is the primary function of the fan in a turbofan engine?

Which action should you take?

Choose only one option

To direct airflow into the turbine stage for power extraction.

To provide the necessary airflow for the engine core.

To assist in fuel combustion by increasing engine pressure.

To cool the engine and maintain optimal airflow into the core.

Question 3: Which technology is used to prevent compressor stall in jet engines?

Which action should you take?

Choose only one option

Variable stator vanes

Compressor bleed valves

Enhanced fuel injection systems

High-pressure air extraction

Question 4: Which protection method is commonly used for preventing short circuits in high-voltage DC systems in aircraft?

Which action should you take?

Choose only one option

To prevent system-wide electrical fires in the event of a failure.

Fusing the system to prevent overcurrent damage.

Grounding the system to avoid interference.

To manage over-voltage situations and ensure safety.

Question 5: In terms of avionics, which type of power supply is preferred for noise-sensitive equipment?

Which action should you take?

Choose only one option

Switching regulators for efficient power conversion.

Linear regulators for stable voltage output.

To provide constant voltage to all avionics equipment.

Question 6: In flight dynamics, what is the primary effect of a positive pitching moment on an aircraft?

Which action should you take?

Choose only one option

It increases the aircraft's angle of attack

It causes the aircraft's nose to pitch up

It leads to a reduction in the lift coefficient

It results in a decrease in the aircraft's stability
