The COMPASS test: a complete guide
COMPASS is the aptitude screening battery many flight training organisations put candidates through before accepting them onto a course — which makes it, for a great many pilots, the first real gate in their career. This guide covers all nine components, explains the control tasks that catch people out, and sets out what is genuinely worth revising.

What is the COMPASS test?
COMPASS is a computer-based pilot aptitude screening system, long established in European flight training. It is designed to answer one question before an organisation commits to training you: do you have the basic coordination, numeracy, memory and spatial ability that flight training will demand?
Its shape reflects that purpose. Rather than a small number of very deep tests, COMPASS samples broadly — hand-eye control, mathematics, memory, orientation, technical understanding, verbal reasoning and aviation English. The result is a profile across abilities rather than a single number, and organisations tend to care about the shape of that profile as much as its average.
Compared with cut-e, COMPASS feels more conventional and less like a set of video games — but the control tasks are demanding, and the mathematics is genuinely time-pressured.
Who uses COMPASS
The most common context is flight school entry screening. Many training organisations require a COMPASS pass before offering a place, both to protect their own training statistics and to avoid taking money from candidates unlikely to complete. Some airlines and cadet programmes use it or components of it as well.
The practical implication is that COMPASS often comes very early — before you have any aviation experience to fall back on, and sometimes before you have thought seriously about aptitude testing at all. Candidates frequently sit it with no preparation because nobody told them it could be prepared for. It can.
The structure of the battery
COMPASS runs as a sequence of subtests, each briefed and then timed. Sessions typically last one to two hours depending on which components are included, and are usually supervised at the training organisation, often alongside an interview or group exercise.
The components divide into three kinds, and it is worth being clear about which is which when you plan your preparation:
- Trainable by revision — the technical test and much of the mathematics. Real content, genuinely learnable.
- Trainable by practice — the control and slalom tasks, and the multitasking element. Skills that improve with repetition.
- Closer to raw aptitude — memory and orientation. Still worth rehearsing for format familiarity, but expect smaller gains.
Every COMPASS test explained
Each links to a full description and a playable practice version.
Hand-eye control
COMPASS opens with its psychomotor tasks. They are the least familiar part of the battery and the part candidates most regret not practising.
Numerical & memory
The cognitive core: arithmetic under time pressure and holding information while something else demands attention.
Orientation & multitasking
Where COMPASS starts to feel like flying: reading instruments and managing several demands at once.
Technical, verbal & English
The knowledge-adjacent components — the parts of COMPASS you can genuinely revise for.
The control tasks: what actually works
Control and Slalom are where unprepared candidates lose the most, and the failure mode is remarkably consistent: over-correction. Faced with a target drifting away, the instinct is a large, fast input, which overshoots, which demands an opposite input, and within seconds you are oscillating rather than tracking.
What works is the opposite. Small, early, anticipatory corrections. Watch where the target is going rather than where it is, lead it slightly, and accept a small steady error instead of chasing a perfect one. Pilots describe this as flying attitude rather than chasing the needle, and it is a learnable habit — but only if you have practised long enough for the panic response to fade.
Practise these in short sessions rather than long ones. Fifteen focused minutes several times a week will improve your tracking far more than an occasional hour, because the skill consolidates between sessions.
How to prepare for COMPASS
- Revise the technical content properly. Forces, moments, levers, pulleys, pressure, basic electricity and motion. This is the most revisable part of any major pilot battery and it is frequently neglected.
- Drill speed-distance-time and fuel calculations until they are automatic. Mental arithmetic without a calculator underpins the maths component.
- Practise the control tasks in short, frequent sessions, concentrating on small anticipatory corrections rather than on score.
- Train memory with interference. Recalling a list is easy; recalling it after being made to do something else is the actual task.
- Listen to aviation English in varied accents. Real radio exchanges are the best preparation — the difficulty in the English component is usually accent and pace, not vocabulary.
- Rehearse the full sequence once you are comfortable with the parts, so the length of the session is not itself a shock.
Common mistakes
- Arriving unprepared because nobody said you could prepare. The most common story in COMPASS, and the most avoidable.
- Over-correcting in the control tasks. Large inputs feel decisive and produce oscillation.
- Skipping the technical revision. It is straightforward content and it is marks you are simply choosing not to take.
- Reaching for a calculator in practice. You will not have one, so train without one from the start.
- Ignoring the English component if you are a native speaker. The difficulty is accent and pace under time pressure, not language ability.
Frequently asked questions
What is the COMPASS test?
COMPASS is a computer-based pilot aptitude screening battery used widely by flight training organisations, and by some airlines, to assess candidates before a course or a cadet programme. It combines hand-eye control tasks done with a joystick or stick control with tests of mathematics, memory, spatial orientation, technical understanding, verbal reasoning and aviation English.
Who uses the COMPASS test?
It is most commonly encountered as entry screening at flight training organisations, where a pass is required before you are accepted onto a course — so for many candidates COMPASS is the first serious aptitude hurdle in their aviation career, sat before any airline is involved. Some airlines and cadet schemes also use it or elements of it. Confirm with the school or operator assessing you.
Can you prepare for COMPASS?
Yes, and more of COMPASS is preparable than of most batteries. The technical and mathematics components reward genuine revision — mechanics, forces, pressure, speed-distance-time and fuel calculations. The psychomotor tasks improve substantially with practice. Only the memory and orientation elements are closer to raw aptitude, and even those benefit from knowing the format so you are not learning the rules on the clock.
How long does the COMPASS test take?
Expect a session of roughly one to two hours covering all the components, though the exact length depends on which subtests the organisation includes and how they run the day. It is usually sat under supervision at the training organisation, sometimes alongside an interview or a group exercise as part of a wider assessment.
Do I need a joystick for COMPASS?
The control tasks are traditionally done with a stick control, and the real assessment will provide whatever hardware it uses. For practice, the important thing is training the underlying skill — smooth, small, anticipatory corrections rather than large reactive ones — which transfers across input devices. Our practice versions work with touch and mouse control.
What is a good COMPASS score?
Thresholds are set by the organisation running the assessment and are not generally published, and they differ between a flight school screening entrants and an airline selecting cadets. Rather than chasing a number, aim to be comfortably above average across every component — because a single weak area is the most common reason otherwise strong candidates are turned down.
