Drag Coefficient
Drag Coefficient is a number that tells how easily something moves through air. Think of it like a score for how streamlined an object is. In aerospace jobs, engineers work to make this number smaller because a lower score means aircraft use less fuel and perform better. When you see this term in resumes, it shows the candidate has experience with making vehicles or aircraft more efficient. It's similar to how car designers work on making cars more aerodynamic, but for aircraft, this is even more important because it directly affects fuel costs and performance.

Example Interview Questions
Senior Level Questions
Q: How would you explain the relationship between cost savings and drag coefficient improvement to management?
Expected Answer: A senior engineer should be able to translate technical improvements into business benefits, explaining how even small reductions in drag can lead to significant fuel savings over an aircraft's lifetime, and provide examples from past projects.
Q: Describe a challenging drag reduction project you led and how you overcame technical obstacles.
Expected Answer: Look for answers that demonstrate leadership, problem-solving, and the ability to manage complex projects while balancing technical requirements with practical constraints.
Mid Level Questions
Q: What methods would you use to measure drag coefficient?
Expected Answer: Should mention wind tunnel testing, computer simulations, and real-world flight testing, showing understanding of when each method is most appropriate.
Q: How do different weather conditions affect drag coefficient?
Expected Answer: Should explain in simple terms how temperature, humidity, and air density can impact measurements and why this matters for aircraft performance.
Junior Level Questions
Q: What is drag coefficient and why is it important?
Expected Answer: Should be able to explain in simple terms that it measures how easily something moves through air and why this matters for aircraft efficiency and performance.
Q: What are the basic ways to reduce drag on an aircraft?
Expected Answer: Should mention basic concepts like streamlining, smooth surfaces, and reducing unnecessary protrusions, showing basic understanding of aerodynamic principles.
