The technical interview is where most pilot candidates feel least confident — and where preparation makes the biggest difference. Across 30 European and Middle Eastern airlines, we've collected over 6,300 technical questions from pilots who shared their assessment experiences on PPRuNe, Reddit, and Glassdoor. The pattern is clear: airlines don't test random ATPL trivia. They test the same subjects, at predictable depth, with follow-up questions designed to separate genuine understanding from memorised answers.
This guide breaks down what airlines actually ask, which ATPL subjects matter most, how deep different airlines go, and how to structure your study plan based on your experience level.

What Airlines Actually Test
Technical questions in airline interviews fall into three categories: ATPL theory (the subjects you studied for your exams), aircraft systems (type-specific knowledge for experienced pilots), and operational application (how you use knowledge in real scenarios).
The balance between these three varies by airline. Low-cost carriers like Ryanair and Wizz Air lean heavily toward operational application — they want to know you can apply performance limitations on a contaminated runway, not recite the formula for calculating accelerate-stop distance. Legacy carriers like Lufthansa and British Airways dig deeper into theory. Middle Eastern carriers like Emirates expect type-specific systems depth if you hold a rating.
Across all airlines, technical questions make up 60-73% of total interview questions — but that doesn't mean 73% of your assessment score comes from technicals. Most European airlines weight HR/CRM competencies at 50-60% of the overall score. The technical interview confirms you have the baseline knowledge; the HR and competency interview determines whether you get hired.
PPRuNe forum data consistently shows that strong HR/CRM scores can compensate for a borderline technical result — but not the reverse. A candidate who aces technicals but stumbles on CRM scenarios rarely gets an offer. — Based on PPRuNe interview debrief threads, 2024-2026
ATPL Subjects by Frequency
Not all ATPL subjects carry equal weight in interviews. Based on our database of 6,300+ technical questions from 30 airlines, these are the subjects that appear most frequently:
| ATPL Subject | Frequency | Typical Topics |
|---|---|---|
| Performance | Very High | V-speeds, climb gradients, contaminated runways, MTOW limitations, wind component effects |
| Principles of Flight | Very High | Stall theory, swept wing effects, high-altitude aerodynamics, Mach tuck, Dutch roll |
| Meteorology | High | Icing types, windshear recognition/recovery, CB avoidance, METAR/TAF decoding, jet streams |
| Aircraft Systems | High | Hydraulics, electrics, pneumatics, fuel, flight controls — type-specific if rated |
| General Navigation | Medium | Great circle vs rhumb line, 1-in-60 rule, INS/IRS principles, RNAV/RNP |
| Operational Procedures | Medium | TCAS RA procedures, approach categories, minima, noise abatement, oceanic procedures |
| Air Law | Low-Medium | Duty time limits (ORO.FTL), RVSM, ETOPS requirements, PBN approvals |
| Human Performance | Low | Hypoxia, fatigue physiology, spatial disorientation — usually tested via CRM scenarios instead |
The top three — performance, principles of flight, and meteorology — account for roughly half of all technical questions across all airlines. If you're short on time, these three subjects give you the highest return on study hours.
How Deep Do Airlines Go?
The same ATPL subject can be tested at wildly different depths depending on the airline. Understanding where your target airline sits on this spectrum is critical for preparation.
Deep Technical (Near-ATPL Exam Level)
Lufthansa, SWISS, Austrian (Lufthansa Group): The DLR-style probing approach. Interviewers ask an opening question, then follow up 3-4 times to test depth.
A question about stall may start with "What causes a stall?" and progressively probe into swept wing effects, Mach buffet boundaries, stick pusher calibration, and the difference between aerodynamic and g-break stall recognition. PPRuNe candidates report that the SWISS technical interview sometimes feels like an oral ATPL exam. The interviewer is typically a TRI/TRE who deliberately pushes until you reach the limit of your knowledge — they want to see how you handle uncertainty, not just whether you know the answer.
British Airways: Technical depth comparable to Lufthansa Group, with emphasis on commercial awareness. Expect questions connecting technical knowledge to operational decisions — "How does high-altitude aerodynamics affect your fuel planning on a transatlantic sector?" BA's technical interview is typically conducted by a fleet captain.
Operational Application (Practical Focus)
Ryanair: Technical paper covers ATPL subjects but questions are practical, not academic. "You're at FL350 and encounter severe icing — what do you do?" rather than "Explain the Bergeron-Findeisen ice crystal theory." The B737 systems component tests whether you understand the aircraft operationally. PPRuNe candidates consistently report that Ryanair cares more about whether you can think under pressure than whether you can recite FCOM limitations.
easyJet, Jet2: Similar operational focus. Technical knowledge is tested through scenarios rather than standalone theory questions. easyJet's assessment integrates technical knowledge into CRM-scored exercises. Jet2's FlightPath cadets are tested on core ATPL theory without type-specific depth.
Type-Specific Systems (Middle East & Legacy)
Emirates, Qatar Airways, Etihad: If you hold a type rating, expect detailed systems questions on that aircraft. Emirates' written technical exam focuses heavily on your current type — B777 hydraulics, A380 electrical architecture, or B737 fuel system depending on your background. The examiners are often ex-Cathay, BA, or Qantas TRIs who have seen every shortcut and will probe weak areas. Qatar tests technical knowledge at interview and again during the assessment in Doha.
Wizz Air: Lower technical proportion overall (51% of questions vs 70%+ at legacy carriers), with heavier weighting on HR competencies, base flexibility, and adaptability. The online technical test covers standard ATPL subjects. Wizz Air's interview culture prioritises cultural fit and operational resilience over academic technical depth.
Ask pilots who recently went through the process at your target airline. PPRuNe threads, airline-specific Facebook groups, and pilot WhatsApp groups provide the most current intelligence on what was actually asked. Assessment processes change — a 2024 thread may not reflect the 2026 format.
Aircraft Systems Questions
Aircraft systems questions deserve special attention because they are the area where experienced pilots are most likely to be caught out. Knowing how to fly the aircraft is not the same as knowing how its systems work.
The four aircraft types most commonly tested in European airline interviews are the A320 family, A330, B737 NG/MAX, and B777/787. Our database contains 362 aircraft systems questions across these types, each with detailed answer frameworks referencing FCOM sections.
| Aircraft Type | Questions | Top Systems Tested |
|---|---|---|
| Airbus A320 | 99 | Flight controls (normal law vs alternate), electrics, hydraulics, ECAM logic, autoflight |
| Boeing B737 | 91 | Hydraulics (A/B/standby), engine (LEAP-1B vs CFM56), fuel system, flight controls, APU |
| Boeing B777/787 | 90 | Flight controls (ACE/PFC), powerplant (GE90/Trent), electrical (B787 no-bleed architecture) |
| Airbus A330 | 82 | Hydraulics (green/blue/yellow), bleed air, pressurisation, fuel (trim tank transfer), TCAS |
The most frequently tested systems across all types are flight controls (how does the aircraft respond to control inputs in normal vs degraded modes), hydraulics (what fails, what's redundant, what you lose), and powerplant (engine limits, indications, failure procedures).
A common PPRuNe-reported pattern: the interviewer asks a broad systems question, then follows up with a failure scenario. "Explain the A320 hydraulic system" becomes "You lose the green hydraulic system — what do you lose?" becomes "Now you lose blue as well — what flight control law are you in?" This cascading failure approach tests whether you understand the system interconnections, not just the components.
Written Tests vs Verbal Interviews
Airlines use two formats for technical assessment — and some use both. Knowing which format your target airline uses changes how you prepare.
Written Technical Tests
Ryanair, Wizz Air, Emirates, Qatar, flydubai, and several other airlines use multiple-choice or short-answer written papers. These typically cover 30-50 questions across ATPL subjects in 45-60 minutes. The format rewards efficient knowledge recall — you need to answer quickly and move on.
For written tests: practise under timed conditions, focus on common traps (performance questions with unit conversions, meteorology questions with METAR/TAF decoding), and don't spend more than 90 seconds on any single question.
Verbal Technical Interviews
Lufthansa, SWISS, BA, KLM, and Air France use verbal interviews where a TRI/TRE or fleet captain asks open-ended questions and follows up based on your answers. The verbal format tests depth, communication, and how you handle not knowing something.
For verbal interviews: practise explaining technical concepts out loud, prepare to say "I'm not certain, but my understanding is..." when you reach the edge of your knowledge, and avoid the trap of over-explaining simple concepts (which wastes time and signals insecurity).
PPRuNe candidates unanimously report: bluffing in a technical interview is worse than admitting you don't know. Interviewers are line pilots and TRIs — they can spot a fabricated answer instantly. Saying "I don't recall the exact figure but I know where to find it" scores better than inventing a number.
Study Plan by Experience Level
Cadets (0-500 Hours)
Focus on core ATPL theory — performance, principles of flight, meteorology, and general navigation. You won't be tested on type-specific systems unless you've completed an APS MCC course on a specific type. Review your ATPL notes, not the FCOM. Practise explaining concepts simply — cadets who use overly complex language raise red flags (it suggests memorisation rather than understanding).
Direct Entry First Officers (500-3,000 Hours)
You'll be tested on ATPL theory at operational depth plus your current aircraft type systems. Spend 60% of study time on your aircraft systems (hydraulics, electrics, flight controls, engines, pressurisation) and 40% on ATPL theory. Know your aircraft limitations cold — Vmo/Mmo, max altitudes, crosswind limits, autoland requirements. Prepare for cascading failure scenarios.
Experienced Pilots (3,000+ Hours / Command Upgrade)
The bar is higher. You're expected to explain systems at a level that demonstrates genuine understanding, not just SOP compliance. Airlines interviewing for direct entry Captains or senior FOs test leadership-oriented technical knowledge: "How would you brief the approach in these conditions?" "What's your personal crosswind limit and why?" Review your type rating training notes, practise teaching concepts to others, and be ready to discuss real-world technical decisions you've made.
At all experience levels, review mental arithmetic — descent planning, fuel conversions, and the 1-in-60 rule come up frequently in both written tests and verbal interviews.
Common Mistakes
Studying the wrong depth. Cadets who memorise A320 FCOM limitations waste preparation time. Experienced pilots who only review ATPL summaries underperform. Match your study depth to the airline's expectations and your experience level.
Neglecting meteorology. Pilots often underestimate how frequently weather questions appear. Icing, windshear, and CB-related questions account for a significant portion of technical questions across all airlines — and they test operational judgment, not just textbook knowledge.
Not practising verbal explanations. Knowing the answer is not the same as being able to explain it clearly under pressure. The difference between "lift is caused by pressure differential over the wing surface resulting from different path lengths" and a crisp, structured explanation matters. Practise with another pilot or record yourself.
Ignoring your weak subjects. Interviewers notice when candidates steer answers toward areas they know well. If your navigation knowledge is weak, that's exactly where a probing interviewer will push. Address weak areas before the interview, not during it.
What Actually Fails People
Based on PPRuNe debrief threads from 2024-2026 across major European and Middle Eastern airlines, these are the technical areas where candidates most commonly fail:
High-altitude aerodynamics. The "coffin corner" question — where low-speed and high-speed buffet boundaries converge — catches candidates who studied stall theory at sea level but never considered the Mach effect. If you're interviewing for a jet position, understand the relationship between Mach number, indicated airspeed, and the buffet onset boundary at high altitude.
Aircraft systems interconnections. Knowing each system individually is not enough. The cascading failure question — "You lose hydraulic system X, now what happens to system Y?" — requires understanding how systems share power sources, what's redundant, and what degrades. This is where the difference between FCOM memorisation and genuine understanding becomes obvious.
TCAS vs ATC conflict. "You receive a TCAS RA that conflicts with ATC instructions — what do you do?" This question appears in our database across 22 of 30 airlines. The correct answer (follow the RA, advise ATC) is simple, but follow-up questions about coordination, reporting requirements, and post-RA procedures trip up candidates who only know the headline answer.
Performance on contaminated runways. Questions about contaminated runway performance — reduced braking action, modified V-speeds, stopping distance calculations — appear frequently at airlines operating in Northern European conditions. Know the difference between reported and operational braking action, and understand how contamination reporting (SNOWTAM / GRF) affects your performance calculations.
The strongest candidates treat the technical interview as a professional discussion, not an exam. They explain their reasoning, acknowledge uncertainty honestly, and connect technical knowledge to operational decisions. That approach scores well at every airline.
