Reaction speed is only one aspect of accurate response selection. FEAST I assesses multiple cognitive aptitudes, including attention and decision-making, according to EUROCONTROL’s official candidate guide. An employer-specific test battery does not imply a universally named “Reaction Time Test” or one published millisecond cutoff.

The two free examples below practise recognising a target and applying a changed rule. They contain no timer or latency measurement. They are original written exercises, not official FEAST tasks or substitutes for a properly administered psychometric assessment.

Begin with the free official EUROCONTROL FEAST training platform for FEAST I familiarisation; the FEAST Part 1 overview explains the wider context.

What to practise: selecting the correct response

In a speeded task, a candidate must first determine whether a stimulus meets the stated condition. Acting too early can be just as unhelpful as missing the target.

On mobile, swipe the table horizontally. Keyboard users can focus the table region and scroll sideways.

SkillIndependent drillCheck afterwards
Go/no-go selectionRespond only to stimuli satisfying every ruleFalse responses to distractors
Choice reactionChoose different actions for different conditionsWrong action despite noticing the target
Rule switchingChange the active condition partway through a sequenceUsing the previous rule after the switch
Timed accuracyCompare accuracy on newly generated itemsRushing into errors as the pace increases

These are independent training methods. The public FEAST description does not guarantee a separate live assessment matching this table.

Free exercise 1: respond or withhold

Original educational exercise - not a time-measuring test.

Imagine a signal appears only when both conditions are satisfied:

  1. The symbol is a triangle (△).
  2. The following digit is even.

Read this eight-item sequence, and note the item numbers for which you would respond:

1 △4 · 2 ○6 · 3 △7 · 4 □2 · 5 △2 · 6 ○3 · 7 △8 · 8 □4

Reveal which three signals qualify

Answer: items 1, 5 and 7 (three responses). They are △4, △2 and △8. Item 3 shows a triangle with an odd digit; items 2, 4 and 8 have even digits but the wrong shape. Item 6 matches neither condition. Both conditions must be true before responding.

If you mark a circle or square with an even number, that is a false response. If you miss a matching triangle, that is a miss. Both are useful error categories.

Free exercise 2: the rule changes halfway through

Original written example; no actual reaction time is recorded.

The first four items use this rule: respond to even digits.

The last four items use a new rule: respond to odd digits.

On mobile, swipe the table horizontally. Keyboard users can focus the table region and scroll sideways.

ItemDigitActive rule
12Even
25Even
36Even
44Even
57Odd
68Odd
79Odd
83Odd

Which item numbers should receive a response?

Reveal the rule-switching answer

Answer: items 1, 3, 4, 5, 7 and 8 - six responses. The first four items qualify at 1, 3 and 4 because the digits are even. After the rule changes, items 5, 7 and 8 qualify because their digits are odd. Item 6 is even but appears after the rule switch and must be ignored.

This example tests reading and retaining the active rule, not real-world latency. Try a new sequence and a different switch point to avoid memorising these answers.

How reaction practice differs from FEAST II

EUROCONTROL describes FEAST II as more complex multitasking work-sample tests, naming RADAR and possibly MULTI-PASS on its current candidate website. A simple shape-or-number response is not a FEAST II radar simulation.

You may encounter DART in historical materials or commercial catalogues. Do not equate that term with an additional confirmed current official module. Read FEAST Part 2 and FEAST multitasking instead of relying on vendor terminology.

How to practise without claiming a measured improvement

Begin untimed with new symbols, conditions and ordering. When a mistake occurs, ask whether you misunderstood the target, retained the wrong rule or responded before checking all conditions.

Do not select an arbitrary “must reach 90%” score as an official FEAST threshold. A written drill also cannot tell you how many milliseconds you would take in an actual supervised test. Hardware, presentation, task instructions and scoring methods differ.

For complementary selective attention problems, use FEAST attention and for mixed original aptitude practice use FEAST sample questions.

Official free practice, timing and limitations

EUROCONTROL’s free official platform provides account-based familiarisation with almost all FEAST I tasks, apart from a test needing special hardware. It does not include FEAST II. Its FAQ explains that practice items, display and rules can differ from live assessments.

EUROCONTROL recommends around eight hours maximum on its official platform as a rule of thumb, rather than a compulsory number of sessions. Home scores are not reliable predictors and are not sent to recruiting organisations.

EUROCONTROL also says this is the only FEAST practice software it authorises. A paid simulator’s faster response time is not proof that an applicant has passed a real FEAST threshold.

Why this page uses a general illustration

An earlier version used a SkyTest “Spot the Side” spatial-orientation screenshot as the hero for a reaction-time guide. That could imply an unrelated commercial task was an official speed test. It has been replaced by a general ATC illustration, with no claim that it displays a FEAST interface.
