Sample Imperial College London Aeronautical Engineering Interview Questions

Real Aeronautical Engineering interview questions in the style Imperial College London asks. Try answering each one aloud before you reveal the hint.

01

Sketch two curves on the same axes and compare their gradients.

Problem-Solving

entry

Hint

Anchor both curves at x = 0, then compare values and gradients for positive and negative x.

02

A light string passes over a smooth pulley connecting two masses. Describe how you would find the acceleration and tension.

Problem-Solving

mid

Hint

Draw a separate free-body diagram for each mass and write Newton's second law along the direction of motion.

03

For a stone thrown in a parabolic path with air resistance neglected, how would you find the time of flight and horizontal range?

Problem-Solving

entry

Hint

Resolve the initial velocity into horizontal and vertical components and treat vertical motion first.

04

A cyclist rides into a headwind and the drag force is proportional to the square of relative air speed. How does the required power scale with speed?

Problem-Solving

mid

Hint

Use power as force times velocity, but be careful about which velocity the drag law uses and which velocity sets the ground speed.

05

A particle on an inclined plane is connected by a string over a pulley to another mass. How would you decide whether the system moves, and in which direction?

Problem-Solving

mid

Hint

Resolve the weight of the particle on the slope parallel to the plane and compare it with the hanging weight, including friction only if specified.

Structured interviews that combine technical problem-solving with motivation and personal statement discussion.

Imperial interviews vary by department. Engineering and Computing tend to be technical with problem-solving elements. Medicine uses a Multiple Mini Interview (MMI) format with several short stations. Most interviews last 15-30 minutes and may include a presentation or group exercise.

15-30 minutes (Medicine MMI: 5-8 minutes per station)1-2 interviews (Medicine: 6-8 MMI stations)
  • -Imperial interviews are more structured than Oxbridge and may include specific scoring criteria.
  • -For Engineering and Computing, expect to solve problems on a whiteboard or paper in front of the interviewer.
  • -For Medicine, practise MMI-style ethical scenarios and communication stations.
  • -Be prepared to discuss your personal statement in detail, particularly any projects or work experience mentioned.

1 questions
01

A ball is dropped onto a vertical spring. How would you estimate the maximum compression of the spring?

hard

Hint

Use energy conservation from release to maximum compression, remembering that gravitational potential energy changes during compression.

Conceptual & Discussion

6 questions
01

Explain how an aircraft is able to take off and stay in the air.

entry

Hint

Start with the four forces and then explain how lift changes with speed, wing shape and angle of attack.

02

A see-saw is balanced with two children at different distances from the pivot. What changes if one child moves closer to the pivot?

entry

Hint

Think in terms of moments, not just forces.

03

When an aircraft burns fuel during flight, why might its centre of gravity matter for stability and trim?

mid

Hint

Connect the centre of gravity to pitching moments and to the lift force acting through a centre of pressure.

04

Why does drag usually increase when speed increases, and why is this a serious design constraint for aircraft?

mid

Hint

Separate the qualitative idea of pushing more air per second from the mathematical scaling of dynamic pressure.

05

How would you explain the difference between lift, thrust, drag and weight to someone who thinks an aircraft simply points upward to fly?

entry

Hint

Use directions of forces first, then explain that velocity and acceleration need not point in the same direction as every force.

06

A ball bounces elastically inside a curved half-pipe. What quantities would you expect to be conserved, and what would you not assume?

hard

Hint

Distinguish energy conservation from momentum conservation in a collision with a fixed surface.

Personal Statement

4 questions
01

Why do you want to study Aeronautical Engineering, and why at Imperial rather than a broader mechanical-engineering course?

entry

Hint

Give a specific academic reason tied to flight, fluids, structures, control, propulsion or design rather than prestige alone.

02

Tell me about an internship, online course, project or independent reading experience that changed how you think about aerospace engineering.

entry

Hint

Focus on one concrete example, what you did, what was difficult and how it changed your next question.

03

What topic in aerospace engineering have you changed your mind about recently, and why?

mid

Hint

Choose a topic where evidence or calculation changed your view, not a vague preference.

04

How would you use a flight-test laboratory experience to connect measurements in the aircraft to the equations you study on the ground?

mid

Hint

Mention at least one measurable quantity, such as airspeed, altitude, acceleration, pitch angle or pressure, and link it to a model.

Curveball

2 questions
01

Estimate how many footballs could fit inside a passenger aircraft, and state your assumptions.

mid

Hint

Approximate the aircraft cabin as a simple geometric volume, estimate a football volume, then apply a packing factor.

02

A chain appears to rise out of a pot before falling, forming a chain fountain. What physical effects could explain the upward motion?

hard

Hint

Start with momentum change and constraints at the pickup point rather than assuming the chain is pulled upward by magic.

Frequently Asked Questions

Yes. Official Imperial Aeronautics admissions page states: 'Applicants will be invited for an interview with our academic staff should they exhibit excellent cumulative performance throughout the admission stages.' Shortlisted applicants are invited to an online e-interview testing technical ability, reasoning through engineering-style problems, interest in aeronautics, motivation for Imperial, and clarity of explanation.
Mathematics 1, Mathematics 2 and Physics for Aeronautical Engineering. All candidates must sit Mathematics 1, and must sit two further modules. These three are required for Aeronautical Engineering.
Each ESAT module is 40 minutes with 27 multiple-choice questions. Candidates take three modules for 120 minutes total. No calculator or dictionary is allowed, and there is no pass/fail score. Scores are reported on a 1–9 scale per module.
A*A*A or A*AAA at A-level, with A* in Mathematics and A*/A in Physics (A* required if applying with three A-levels, at least A if applying with four A-levels). A-level entry requirements verified via UCAS course data and course mirrors. For IB, 40 points overall, with 7 in Mathematics at higher level and 7 in Physics at higher level.
Further Mathematics is strongly encouraged but not listed as essential in current course-data mirrors. It remains highly useful preparation for ESAT and interview problem solving.
Both. Public reports and indexed department material indicate motivation/personal-statement questions plus technical maths and physics questions. The stated areas tested are technical ability in Mathematics and Physics, reasoning through unfamiliar engineering-style problems, interest in aeronautics, motivation for Imperial, and clarity of explanation.
October 12–16, 2026 and January 4–8, 2027. Candidates may only sit the ESAT once per admissions cycle and must check whether Imperial accepts either sitting or prefers October.
No. UAT-UK states candidates are only permitted to register once for a test in either October or January per admissions cycle. Applicants should check the current UAT-UK rules before booking.
International applicants should check country-specific entry requirements, English-language requirements and test-centre availability early. Imperial states that all home, EU and overseas applicants must demonstrate English-language competency for their course.
