Question 2: How do simulation tools for aerodynamics handle the challenge of simulating compressible flow in high-speed flight?

Which action should you take?

Choose only one option

By simplifying the flow models to reduce computational requirements

By using specialized solvers for compressible Navier-Stokes equations

By simulating flow at subsonic speeds only

Question 3: What is the significance of "Real-Time Simulation" in aerospace systems, and how does it differ from offline simulation in terms of performance and complexity?

Which action should you take?

Choose only one option

Real-time simulation provides immediate feedback for system testing, requiring low-latency performance and high reliability, but it is computationally intensive

Offline simulation is always preferred as it is more accurate

Real-time simulation simplifies the model but sacrifices accuracy

Real-time simulation is only necessary for gaming, not aerospace applications

Question 4: In a safety-critical aerospace system, what is the impact of "Undefined Behavior" in C/C++ code, and how do you prevent it in your software development?

Which action should you take?

Choose only one option

Undefined behavior only affects software, not hardware systems

Undefined behavior is only a concern in high-level languages, not in C/C++

Undefined behavior can lead to unpredictable results and system failures, and it is prevented by adhering to coding standards and rigorous testing

Undefined behavior is ignored if the system is adequately tested

Question 5: How does "Monte Carlo Simulation" help in modeling uncertainty in aerospace systems, and what challenges do you face when implementing this technique?

Which action should you take?

Choose only one option

Monte Carlo simulations use random sampling to model uncertainty, but challenges include ensuring the accuracy of input data and managing computational cost

Monte Carlo simulations are irrelevant in aerospace systems

Monte Carlo simulations only apply to financial systems, not aerospace

Monte Carlo simulations are only useful for testing software, not hardware systems

Question 6: How does ECC (Error Correction Code) memory enhance reliability in aerospace embedded systems?

Which action should you take?

Choose only one option

By detecting and correcting single-bit memory errors

By managing large data packets

By improving memory access speed
