Aircraft Engineers Need Aviation English Too

When people discuss aviation English training, the conversation almost always centres on pilots and air traffic controllers. This is understandable. ICAO language proficiency requirements apply directly to those licence holders, and the consequences of miscommunication on the flight deck or over the radio are well documented.

But there is another group of aviation professionals for whom clear English is equally critical, and who receive significantly less attention in the language training conversation: aircraft engineers.

The Written Record Matters

Every time an aircraft engineer completes a maintenance task, inspects a system, or identifies a defect, they produce a written record. That record may be read by a pilot conducting a pre-flight check, a colleague completing a related task on the same aircraft, an airworthiness inspector, or, in the event of an incident, an accident investigator.

Ambiguous language in a technical log entry is not a minor issue. It can lead to a defect being assessed incorrectly, a repeat inspection being skipped, or a safety critical item being signed off by someone who interpreted the entry differently from the engineer who wrote it.

Technical Manuals Are Written in English

The majority of aircraft manufacturer documentation is written in English. Aircraft Maintenance Manuals, Fault Isolation Manuals, Service Bulletins, Airworthiness Directives, Wiring Manuals, and many other technical publications require engineers to read, interpret, and apply information accurately.

A misread procedure, a misunderstood limitation, or an incorrectly interpreted warning can have consequences that extend far beyond paperwork.

Communication With Flight Crew

Engineers frequently communicate directly with pilots. They may explain the nature of a defect, describe the scope of a repair, discuss deferred maintenance items, or advise on operational limitations.

A pilot making a go or no-go decision based on an engineer’s explanation needs to receive exactly the information that was intended. The engineer must also be confident that the pilot has understood the technical implications correctly.

Human Factors and Maintenance Communication

Communication has long been recognised as an important human factors issue in aircraft maintenance.

Many maintenance errors do not result from a lack of technical knowledge. Instead, they occur because information is misunderstood, omitted, assumed, or communicated unclearly during shift handovers, troubleshooting discussions, or maintenance coordination activities.

For this reason, effective communication forms part of many maintenance human factors programmes and safety management systems.

Aviation English for Engineers

Aviation English training for engineers is not the same as training for pilots. It does not focus on radiotelephony phraseology. Instead, it addresses technical reading comprehension, precision in written defect reporting, vocabulary specific to airframe, engine, avionics, and systems maintenance, and the kind of spoken communication that occurs in a hangar or on a stand.

At ICAO Level 4 to 5, engineers should be able to read a maintenance manual task card accurately, write a defect entry that is unambiguous to any qualified reader, and explain a technical issue clearly to a colleague or flight crew member — even under time pressure.

Training should reflect the language tasks engineers perform in the workplace.

ICAO Levels and Aircraft Engineers

Unlike pilots and air traffic controllers, aircraft engineers are not subject to ICAO Language Proficiency Requirements under Annex 1.

However, many airlines, maintenance organisations, and aviation employers require engineers to demonstrate a level of English broadly comparable to ICAO Operational Level 4 or above. This reflects the reality that maintenance documentation, technical records, and operational communication are frequently conducted in English.

The objective is not regulatory compliance with an ICAO language endorsement. The objective is ensuring that engineers can perform their duties safely, accurately, and confidently in an international aviation environment.

Assessing Maintenance English

Many maintenance organisations have English requirements on paper. Fewer have structured programmes to develop and verify that competence. With an increasingly international workforce and documentation requirements that will not change, this gap carries real risk.

General English examinations do not necessarily measure the communication skills required in aircraft maintenance.

An engineer may achieve a satisfactory score on a general English test while still struggle to interpret technical documentation, describe maintenance activities accurately, or communicate effectively during troubleshooting and handovers.

Aviation English Asia Ltd works with maintenance organisations across the region to assess current competence levels and develop training programmes tailored to the engineering environment. If your organisation is looking at this area, we are happy to discuss what a practical programme might involve.

The AEROSTAF Aircraft Maintenance Language Test (AMLT) has been developed specifically for aircraft maintenance personnel. It assesses the language skills required in maintenance environments and provides organisations with information that is directly relevant to operational performance.

If you’re an ab-initio pilot, a line pilot, or an ATCO, you’ve probably sat an Aviation English test and thought:

“This doesn’t really feel like how we actually communicate.”

At Aviation English Asia Ltd, we agree - and that belief drives how we design training and how we evaluate tests.  Poorly designed Aviation English tests don’t just feel frustrating - they can:

• reward memorisation instead of decision-making,
• penalise competent pilots who communicate efficiently,
• fail to identify candidates who struggle with real-time interaction
• and demotivate candidates from improving their language proficiency.

In other words, test design is not just an academic issue. It directly affects safety, fairness, and careers.

Before going further, I would like to introduce two terms:

• The AEROSTA Framework is the Aviation English Rating, Syllabus, Test Analysis Framework - a principled way of analysing what Aviation English tests should measure and how tasks should elicit valid evidence.

• AEROSTAF refers to a family of role-specific tests built using that framework (for example, AEROSTAF Cadet Pilot Language Test and AEROSTAF Airline Pilot Language Test).

This article explains, in plain language:

• what valid Aviation English testing really means,
• what often goes wrong in poorly designed tests,
• and how AEROSTAF tests, guided by the AEROSTA Framework, are built using data and science.

What “validity” actually means (in one sentence)

In assessment terms, a test is valid if it measures the skill it claims to measure - not something easier, more convenient, or only loosely related.

For Aviation English, that skill is operational communication, not storytelling, not technical knowledge, and not exam technique.

Test validity: more than “aviation topics”

A common misconception is that a test is valid if the candidate:

• talks about aviation,
• mentions emergencies,
• or uses technical vocabulary.

That’s not what ICAO intended.

ICAO guidance is clear: Aviation English tests must assess whether a candidate can communicate effectively in operational contexts, not simply talk about aviation.

That means evidence of:

• comprehension (especially under operational pressure),
• interaction, and
• the ability to perform the right communicative function at the right moment.

Listening tests: what should they really assess?

Listening is a concern for many candidates, and they consider it a matter of luck if they can hear all the words.  Many listening tests focus narrowly on:

• recognising words,
• spotting keywords like “Mayday”, "we have a problem here", and "engine failure"
• or answering multiple-choice questions about factual detail.

These tasks can have a place - but only as supplementary evidence.

Poor listening tasks often over-assess:

• keyword spotting,
• recognition of emergency labels,
• and test-taking strategy.

What they under-assess is whether the listener understands what needs to happen next.

In real operations, listening is rarely passive.  You listen in order to respond.

That’s why well-designed listening tasks:

• use realistic inputs (ATC transmissions, crew messages, briefings),
• and require the candidate to act on what they heard, not just recognise it.

In AEROSTAF listening tasks, comprehension is demonstrated through appropriate operational response, not by getting a tick in the “right” box.

Interaction: the core of Aviation English

At the top of the ICAO language “pyramid” is interaction.

Interaction is not:

• how quickly you respond to an assessor,
• long explanations,
• polished general English,
• or narrating procedures from memory.

Interaction is:

• refusing an unsafe instruction,
• requesting clarification when information is ambiguous,
• warning about a conflict,
• stating intentions clearly,
• correcting misunderstandings,
• and doing all of this efficiently and intelligibly.

For example, safely refusing an ATC instruction requires:

• recognising a constraint,
• signalling non-compliance clearly,
• and offering an alternative or stating intentions.

That is interaction - not explanation.

Many traditional test questions fail here.

Questions like “What would you do in this situation?” often produce:

• procedural narration,
• checklist explanations,
• or hindsight-based reasoning.

They may sound impressive - but they do not reliably test interaction.

How the AEROSTA Framework shapes better tasks

Under the AEROSTA Framework, tasks are designed around one central principle:

Communicative functions must be necessary to complete the task.

In other words, the candidate cannot succeed unless they actually perform the interaction.

Core design features

1. Mixed-mode input

• Written context: who you are, where you are, phase of flight
• Audio trigger: an ATC instruction, silence, error, or new information

2. No lexical “hand-holding”

• Prompts avoid telling candidates what to say
• No labels like “engine failure” or “request priority” appear in the task text

3. Immediate response required

• The candidate must respond now, just as in real operations

4. Phraseology first

• Standard ICAO phraseology is expected wherever it suffices
• Plain language is used only where phraseology genuinely runs out (for example, security or medical situations)

This is how AEROSTAF tests transform linguistic data into practical tests

A simple example

❌ Poorly designed task

You have an engine failure after takeoff. What would you do? Explain why.

This mainly tests:

• technical knowledge,
• narration,
• and test-taking strategy.

✅ AEROSTAF-style task

Context:

You are Speedbird 432, passing 2,000 ft after departure.

One engine parameter is outside normal limits.

ATC (audio):

“Speedbird 432, climb to five thousand feet.”

Instruction:

Transmit your response to ATC.

Now the candidate must:

• interpret constraints,
• select the correct communicative function,
• and express it clearly and efficiently.

The resulting utterance is what an ICAO ELP test is supposed to measure.

Why role-specific tests matter

A cadet pilot, an airline captain, and an ATCO do not interact in the same way - and they should not be tested as if they do. AEROSTAF tests are role-specific by design, not by marketing label.

Each test targets:

• the communicative functions most relevant to that role,
• the types of listening and interaction that role actually performs,
• experience
• and the level of linguistic control ICAO expects at that stage.

What this means for you as a candidate

As a candidate you might be tempted to take the easiest test possible as it fulfils the airline requirements.  Those requirements can shift rapidly.  We appeal to your professionalism to train for the needs of the job - not the needs of a test, because the chances are very high that the test does not measure what it claims to do.

• Don’t waste time focusing on a task, eg picture description, scripting model answers, or limiting your listening to the recognition of words  - focus on what the test should be measuring
• Practise responding to instructions, constraints, and ambiguity.
• Aim for clarity, not length.
• Remember: in Aviation English, less but better is often safer.

Our commitment at Aviation English Asia Ltd

At Aviation English Asia Ltd, we don’t just prepare candidates to pass tests.

We care deeply about whether a test is worth passing.  When we first started in 2009 we decided quite deliberately to not get involved in test administration, mostly because we did not want to take on any additional risk of liability in high stakes testing.  But in recent years we have (1) witnessed tests which clearly do not measure what ICAO intended, (2) being used for inappropriate purposes, and (3) administered by organisations actively demonstrating a significant conflict of interest.  The consequences of which are so severe that ICAO ELP testing demotivates candidates from improving the skills which they so urgently need.

We made the commitment to use our knowledge and experience to

• analyse tests using the AEROSTA Framework,
• design and support AEROSTAF role-specific tests,
• train organisations to administer tests ethically,
• and align training with communicative functions, not just aviation topics.

Aviation English testing should reflect operational reality - not tests that are convenient to administer.

Standard phraseology provides a shared linguistic framework for routine aviation communication. Its value lies in predictability and consistency, particularly when speakers come from different linguistic backgrounds.

For cadet candidates, phraseology is often perceived as intimidating. In some ICAO ELP tests it is expected that candidates have a background knowledge of aviation including phraseology.  However phraseology is usually something that is taught during flight training by qualified instructors.  A good ICAO ELP test will inherently require a significant proportion of the test to be direct communication with ATC using standard phraseology, however that should also include appropriate plain English in an aeronautical context when phraseology alone will not suffice.

However many candidates for a cadet programme will not have exposure or prior training in phraseology, so when this type of test is used it can cause the candidate to focus on learning phraseology (which they are conscious is new to them) instead of improving their English in an aeronautical context (which they are not conscious of).  The testing of a candidate on situations which require background knowledge of phraseology not only puts candidates in an unfair position, but also distracts candidates from improving relevant skills at a time which would otherwise be highly motivating.  The training industry also becomes skewed - it causes unqualified English teachers to start teaching phraseology to gullible candidates who would know no better, and causes know-it-all pilots to disregard the importance of appropriate plain English that the tests were intended to assess.

To candidates with pilot licenses it is essential that ICAO ELP tests have a significant radiotelephony component that requires direct communication with ATCO.  The scenarios should be constructed so that the candidate can swiftly change from RT to plain English.  Phraseology alone  can lead to rote memorisation, where phrases are readback accurately but without functional understanding of the context.

Phraseology is not intended to replace language proficiency. It functions effectively only when there is a foundation of proficiency in basic and complex structures.  When situations fall outside standard scenarios, pilots must rely on plain English to clarify, negotiate, and resolve issues.  And the list of possible interactions is far greater than that.

Understanding the role of phraseology, and its place in ICAO ELP assessment is essential for cadet-level preparation.  In our view, ICAO ELP assessments aren't appropriate for ab initio cadet selection.  So what about ICAO tests without a radiotelephony component? These tests actually undermine the role of valid ICAO ELP tests, by testing skilled candidates on the wrong thing, and unskilled candidates on the right thing.  

Conclusion

• regardless of test used, Aviation English Asia Ltd courses are an appropriate training solution

• Aviation English Asia Ltd teachers are qualified and experienced in teaching phraseology 

• airlines and flight schools should adopt the AEROSTAF Cadet Pilot Language Test for cadet selection

• tests for licensed pilots and ATCOs must include a radiotelephony component or should be replaced

• ICAO ELP tests must be constructed in such a way that the test scenarios necessitate a wide variety of communicative functions that might not necessarily be covered by standard phraseology

Language proficiency standards in aviation were introduced to address safety risks arising from miscommunication in operational environments. Their role is fundamentally protective, not predictive.

The International Civil Aviation Organisation developed language proficiency descriptors to define minimum acceptable performance levels for licensed personnel operating in international airspace. These descriptors focus on intelligibility, clarity, and interaction in operational contexts.  That specifically means pilot to controller communication on the radiotelephone.

These standards were not designed to assess learning capacity, instructional comprehension, or suitability for ab-initio training. When ICAO language tests are used as cadet selection tools, they are being applied beyond their original scope.

This creates a structural problem. Candidates prepare for what is measured, and training systems then inherit the consequences of that preparation. Passing a compliance-based test may satisfy regulatory requirements, but it does not reliably indicate readiness for the communicative demands of training.

Common Misconceptions

• ICAO language tests measure training suitability

• ICAO levels reflect learning potential

• Compliance standards predict training performance
