Algerian Civil Aviation Authority and Language Solutions Algeria
Algeria’s aviation industry is growing at a rate of over 12% per year. Passenger traffic for both domestic and international flights is significantly increasing. Algeria controls a large airspace with overhead traffic from both the Middle East and Europe.
Language Solutions Algeria is a prestigious English language training organisation that implements a variety of language training and testing products from providers such as IELTS, Cambridge University and RMIT Training.
Algeria’s Civil Aviation Authority recognised the need to improve the English language proficiency of the pilots of its national and domestic carriers and its air traffic controllers.
It also needed to increase its capability to train and test personnel in order to meet the ICAO Language Proficiency Requirements, which would help ensure safe passage for international carriers and enable its national carrier to increase its networks internationally.
RMIT English Worldwide sought out the best language training partner to provide a strategic fit for Algeria’s Civil Aviation Authority (CAA), and found Language Solutions Algeria (LSA).
We then worked with both organisations to analyse the specific language needs of their aviation personnel.
In addition, we created a test centre to deliver RELTA. RMIT English Worldwide and LSA continue to provide English language support to the aviation industry in Algeria.
Oman Aircraft Control College
Oman Aircraft Control College is a joint civil and military training college located in Muscat that provides air traffic control, air defence and ancillary training at all levels.
Most of the training at the college is delivered in English, and participants need to have a good grasp of the English language to achieve the best results.
All graduates from the college are expected to meet the ICAO Language Proficiency Requirements.
Participants build their English language proficiency by doing our General English for Aviation course along with their other studies.
We trained the College’s team of Aviation English trainers to deliver the course.
Graduating students sit RELTA to attain their ICAO English language proficiency licensing requirement.
Qatar’s national carrier needed to expand its network of international destinations to meet its goal of becoming one of the world’s most renowned airlines.
Its Civil Aviation Authority had not yet endorsed an Aviation English test to enable its aviation personnel to fulfil the ICAO Language Proficiency Requirements.
Qatar Airways employs pilots with different international backgrounds and varying levels of English language proficiency. They required a flexible and reliable test to check whether their pilots met ICAO’s Language Proficiency Requirements.
RMIT English Worldwide worked with Qatar Airways to successfully demonstrate the validity and reliability of RELTA, which ensured its endorsement from the civil aviation authority.
We created a RELTA test centre at Qatar Airways and provided training for Qatar Airways’ own RELTA examiners and raters. Within 4 months of receiving endorsement from the Civil Aviation Authority, all pilots from Qatar Airways had been tested.
Russian Civil Aviation Authority and the Moscow Aviation Institute (MAI)
MAI is a premier engineering university dedicated to aerospace technologies and training. Russian aviation personnel typically had low levels of English language proficiency.
The industry recognised that this low level of English language proficiency posed a serious safety risk, and also impacted on the ability of its carriers and pilots to work outside of Russia.
MAI needed a holistic training and testing solution for pilots and air traffic controllers to improve their proficiency to an operational level, and an internationally recognised test that proved their compliance with the ICAO Language Proficiency Requirements.
Recognising the effects of language erosion, MAI also identified the need for recurrent training of aviation personnel after they had been tested, and to prepare for their next Aviation English test.
RMIT English Worldwide worked with MAI to deliver a training program that helped over 2000 pilots and air traffic controllers develop their proficiency to ICAO Level 4 (Operational), and in some cases Level 5 (Extended).
We created a RELTA test centre at MAI and developed a recurrent training program that provides Beyond Level 4 training. These steps ensure aviation personnel can maintain their English language proficiency between tests as well as prepare for their next test.

Why is English language proficiency important?
These extracts from ICAO’s Manual on the implementation of ICAO language proficiency requirements explain why ICAO strengthened its language proficiency requirements.
Background to strengthened ICAO Language Proficiency Requirements
Over 800 people lost their lives in three major accidents (one collision on the ground, one accident involving fuel exhaustion and one controlled flight into terrain). In each of these seemingly different types of accidents, accident investigators found a common contributing element: insufficient English language proficiency on the part of the flight crew or a controller had played a contributing role in the chain of events leading to the accident. In addition to these high-profile accidents, multiple incidents and near misses are reported annually as a result of language problems, instigating a review of communication procedures and standards worldwide. Such concern was heightened after a 1996 mid-air collision in which 349 passengers and crew members were killed in an accident in which insufficient English language proficiency played a contributing role.
Accident investigators usually uncover a chain of events lining up in an unfortunate order and finally causing an accident. In some instances, the use (or misuse) of language contributes directly or indirectly to an accident.
At other times, language is a link in the chain of events which exacerbates the problem. There are three ways that language can be a contributing factor in accidents and incidents:
- incorrect use of standardized phraseologies;
- lack of plain language proficiency;
- and the use of more than one language in the same airspace.
Incorrect use of standardized phraseologies.
The purpose of phraseologies is to provide clear, concise, unambiguous language to communicate messages of a routine nature. One study of real en-route radiotelephony communications (Mell 1992) revealed that 70 per cent of all speech acts uttered by native and non-native speakers, and for which a phraseology is prescribed, are not compliant with the recognized standards. For phraseologies to have the most significant safety impact, all parties need to use ICAO standardized phraseology … while ICAO standardized phraseology has been developed to cover many circumstances, it cannot address all pilot and controller communication needs. It is widely acknowledged by operational and linguistic experts that no set of standardized phraseologies can fully describe all possible circumstances and responses.
Lack of plain language proficiency.
This is often cited as having played a contributing role in some accidents. In one example, the controller last in contact with the unilingual English-speaking crew which strayed off course and crashed into a mountainside acknowledged to accident investigators that the flight’s position reports were incongruent with where he understood their position to be. However, by his own admission, he lacked plain English proficiency to clarify his doubts or to notify the crew that they were off course.
The use of two languages in the same airspace.
This can have an impact on the situational awareness of flight crews who do not understand all the languages used for radiotelephony in that airspace and has been cited in several accident reports as a contributing factor.
While the focus of ICAO language proficiency requirements is on improved aeronautical radiotelephony communications, language also plays a role in cockpit resource management (CRM) and has been cited as a contributing factor in incidents/accidents where miscommunication happened within a flight crew. By meeting language proficiency requirements, flight crews, especially multi-national flight crews, will have the added safety benefit of better CRM.
Concern over the role of language in aviation accidents and incidents has been expressed from several quarters. Data obtained from the ICAO Accident/Incident Data Reporting System (ADREP) database, United States National Transportation and Safety Board reports (ASRS), the United Kingdom Mandatory Occurrence Reporting System (MORS) and Confidential Human Factors Incident Reporting Programme (CHIRP) corroborate that the role of language in accidents and incidents is significant. A number of fatal and non-fatal accidents appear in the ICAO ADREP which cite ‘language barrier’ as a factor. These data are further supported in two recent reports by Eurocontrol (Van Es 2004; Van Es Wever & Verbeek 2006).
Academic studies in such fields as natural language processing (Cushing 1994) and sociolinguistics (Linde 1988) have also examined and highlighted the role of language proficiency and language use in aviation incidents and accidents.

If you want to study the Beyond Level 4 course, our online Aviation English training course which is designed as an independent study tool, you can purchase it from this website.
Can I study a course at RMIT English Worldwide to become an Aviation English trainer?
No. RMIT English Worldwide only trains people who are employed by its partner organisations to become Aviation English trainers. If you are interested in becoming an Aviation English trainer, please see Our partners to find a partner in your local area. Then, you can enquire whether they have need of trainers.
How can I become a RELTA examiner or rater?
Our partner test centres that deliver RELTA select potential RELTA examiners and raters with appropriate qualifications and provide their details to RMIT English Worldwide. Those that are found to have the requisite qualifications (including the appropriate level of English language skills) are trained by RMIT English Worldwide and, if successful, accredited to be a RELTA examiner and/or rater for the test centre.
If you are interested in becoming a RELTA examiner or rater, please see Our partners to find a partner in your local area. Then, you can enquire whether they have need of examiners or raters.
What is Beyond Level 4?
See our section above on our Beyond Level 4 online Aviation English training course.
What are the software and hardware requirements of the Beyond Level 4 course?
These are the minimum system requirements:
- Browser—Internet Explorer 6 or higher, Mozilla Firefox 3.5 or higher, Google Chrome 9 or higher, Apple Safari version 4 or higher
- Plug ins—Adobe Flash Player 10.1
- Internet connection—1000 Kbps or higher (Our diagnostic tool will show you the internet connection speed to your computer. If the internet bandwidth is too low the program will be slow.)
- Peripherals—speakers/headphones, microphone.
These are the recommended system requirements:
- Browser—Internet Explorer 9, Mozilla Firefox 3.6, Google Chrome 10, Apple Safari 5
- Plug ins—Adobe Flash Player 10.1 or higher
- Internet connection—1.5 Mbps or higher (Our diagnostic tool will show you the internet connection speed to your computer.)
- Peripherals—high quality headphones with built in microphone.
How does Beyond Level 4 record and stream media?
Beyond Level 4 incorporates the recording of audio and streaming of media over the internet by using a Flash Media Server (FMS). FMS requires your computer to access Port 1935. Most personal computers will access the FMS without a problem. However, some company firewalls block Port 1935, which will prevent the course material from loading or functioning properly. Our diagnostic tool will help you determine whether Port 1935 is available on your machine.
What is the teaching methodology and what are the goals of Beyond Level 4?
Beyond Level 4 is designed as an independent study tool. High level listening and speaking skills are developed for communication in plain English in radiotelephony based and aviation related communication contexts.
How can individuals track their progress in Beyond Level 4?
You can track your progress using inbuilt features of the course, such as tick symbols that appear next to certain completed activities. Please refer to our sample courses and guided video tours. The video tour gives you a clear overview of the whole course (for either pilots or ATC), including a demonstration of its tracking features. The Aviation English trainer assigned to provide feedback to you will also use these functions to track your progress.
How long should it take me to complete Beyond Level 4?
We strongly advise that you complete the course over a 12–16 week period. The course comprises eight units. Aim to complete each unit over a 2 week period. Each unit contains listening comprehension, language structure, pronunciation, vocabulary and speaking activities.
In speaking activities I have to record my answers. How are the answers checked?
Speaking activities are submitted for review by your Beyond Level 4 assessor. The ICAO Language Proficiency Rating Scale is used as the basis for assessment. Individual feedback is forwarded to you following completion of units 1–4 and units 5–8. When you complete Unit 4 and Unit 8, please email us at email@example.com to request assessment.
What accents are included in the Beyond Level 4 Listening Test?
Accents include Australian, British and North American.
Does the speed of the recordings in the listening test vary from slow to fast, or vice versa?
Speed is not modulated throughout the course; however, as the course progresses through each unit, scenarios become more complex and listening activities become longer.
Is there any partner work?
No. Partner work is not required as the course has been designed for independent study.
Will I be able to practise interacting in non-routine scenarios?
Yes. Each of the eight units is based on a different non-routine flight scenario.
After completing the Beyond Level 4 course, how much more likely am I to achieve Level 5 on my next test?
The Beyond Level 4 course provides challenging, true to life scenarios for pilots and air traffic controllers to improve their English language proficiency. As with any language learning, the outcomes are more likely to be achieved when as many opportunities as possible are taken to practise over an extended period of time.
Do you have any recommendations for how to study the Beyond Level 4 course?
We recommend you complete the units in order. Each unit has three sessions and it is best to complete each session in one sitting. However, it is not advised to complete more than one session in a sitting. It would be more valuable to leave a few days between sessions and review a session before moving on.
What is RELTA?
See our section above on our RMIT English Language Test for Aviation.
What does RELTA assess?
RELTA assesses your ability to speak and understand English in aviation contexts, including routine and non-routine radiotelephony communication contexts, with a focus on plain English.
RELTA does not assess your ability to read and write in English, or your knowledge of grammar or aviation.
What are the ICAO Language Proficiency Requirements?
See our section above on the ICAO Language Proficiency Requirements.
Does RELTA meet the ICAO Language Proficiency Requirements?
Yes. RELTA has been trialled extensively with native and non-native English speaking pilots.
The trials found RELTA to be:
- an extremely reliable test
- a valid and effective measure of language proficiency
- an appropriate and valid test for pilots and air traffic controllers (measuring language areas associated with communication in both radiotelephony and face to face contexts)
- an appropriate test instrument for assessing pilots and air traffic controllers in relation to the six core language skill areas identified by ICAO—pronunciation, structure, vocabulary, fluency, comprehension and interactions.
ICAO has conditionally recognised RELTA for Pilots Heavy (up to Level 5), as it conforms with ICAO’s stringent requirements and standards. It is one of only three English language proficiency tests conducted worldwide to be recognised by ICAO’s Aviation English Language Test Service (AELTS). (AELTS does not currently evaluate the validity of Level 6 assessment in English language proficiency tests.)
Who is RELTA for?
RELTA is designed for pilots and air traffic controllers who need to demonstrate English language proficiency to meet the ICAO Language Proficiency Requirements.
Why do I need to sit RELTA?
If you are asked to sit RELTA, it means your organisation needs to demonstrate the language proficiency levels of all personnel to the civil aviation authority in your country, in accordance with the ICAO Language Proficiency Requirements.
Where can I sit RELTA?
RMIT English Worldwide works with approved test centres around the world who deliver RELTA. Please see Our partners to find a RELTA test centre in your local area.
RELTA is also provided at the headquarters of RMIT English Worldwide in Melbourne, Australia.
Tests are scheduled every month at the Melbourne Test Centre:
Level 9, 501 Swanston Street
(enter via Victoria Street)
Tests start at 10.00 am and should be completed by mid afternoon. The fee to sit RELTA is A$258.00.
Check upcoming test dates or book your place online today:
How do I apply for RELTA?
Please contact your local RELTA test centre to register to sit the test. (For your nearest test centre, please see Our partners.) If the organisation you work for is a RELTA provider, they can tell you where you can sit the test and what dates are available. You will need to provide:
- your full name and date of birth
- your pilot licence or ATC licence number
- details of the company or organisation you work for.
What accents are included in the RELTA Listening Test?
Accents include Australian, British, North American, Italian, Brazilian, Indian, Filipino and Indonesian.
How long does RELTA take?
The Listening Test takes 35–50 minutes and the Speaking Test takes 25–30 minutes.
Do I have to sit both Listening and Speaking tests?
Yes. All candidates must do both tests.
Can I repeat one of the RELTA tests?
No. If you are repeating RELTA, you need to sit both tests again, even if you received a low score for only one of the tests. Results from previous tests are not carried forward.
If there is a technical interruption that is beyond your control, one of the tests may be repeated on its own. The test centre where you are sitting the test, in consultation with the Aviation Operations Team at RMIT English Worldwide, will determine whether this will happen.
Is every RELTA test the same?
No. There are many versions of each test type, and systems are in place to randomly assign and monitor the allocation of each version across all test centres.
No candidate will repeat the same test; however, the structure of RELTA remains the same for all versions.
Does RELTA require knowledge of aviation?
Yes. RELTA candidates must have adequate and appropriate aviation experience, including knowledge of flight operations and situations relevant to pilots and air traffic controllers.
RELTA assesses your ability to use radiotelephony language and incorporates radiotelephony words and phrases. It does not test your knowledge of aviation or ICAO standardised phraseology.
How can I prepare for RELTA?
You can do our free listening and speaking practice tests and check your answers in our support materials as many times as you wish. Please see Preparing for RELTA for these resources.
If I complete an RMIT English Worldwide language program before the test, will I get the score I need?
Completing an English language program delivered by RMIT English Worldwide, or another language provider, does not guarantee you will achieve ICAO Level 4, 5 or 6.
Our courses are designed to develop English language skills, and participants should notice an improvement in their confidence when speaking and understanding English. However, these courses will not determine whether a candidate is likely to achieve ICAO Level 4 or above.
What do I need to bring on the day of my RELTA test?
To be permitted to sit the test, on the day, you need to bring your:
- photo identification (pilot licence, ATC licence or passport)
- booking confirmation form (if the test centre has asked for it).
No books, bags, cameras, mobile phones or other electronic devices will be allowed in the test room.
What happens on the day of the test?
You will have to register 30 minutes before the commencement of the test.
You will not be allowed to leave the test room once the test has commenced. Your voice will be recorded in the Speaking Test.
When and how can I get my results?
Results are issued up to 15 working days after the test date. Results and certificates are made available to you from your organisation, directly from the test centre or from your local civil aviation authority. You can also access your results online.
Can I get a replacement RELTA certificate?
RMIT English Worldwide can provide you with a copy of your certificate after we have verified your identity. You will need to email a scanned copy of your pilot licence or ATC licence, your request and a secure address for delivery to firstname.lastname@example.org.
If you wish RMIT English Worldwide to send the replacement certificate through registered or express post, you will need to cover that cost. (The test centre will give you more details.) However, if regular postage is acceptable there will be no charge.
Can I appeal my results or ask that my test be marked again?
Yes. If you feel the result does not accurately reflect your test performance, you can request an appeal. To do this, please contact your local RELTA test centre as soon as possible after receiving your results. They will issue you with a RELTA Candidate appeals form or you can download it yourself.
Completed appeals forms must be lodged with your test centre, who will sign them and forward them to the Aviation Operations Team at RMIT English Worldwide. All requests for appeal must be received by the Team within 21 days of your RELTA result being made available, unless exceptional circumstances apply.
Candidates are required to pay a fee of A$75 to lodge the appeal, which will be refunded if the appeal is upheld by the independent assessor.
How does RELTA assess results? Are RELTA results presented in accordance with ICAO levels?
RELTA assesses your performance using the six core language skill areas identified by ICAO—pronunciation, structure, vocabulary, fluency, comprehension and interactions.
Your lowest score on any criterion will determine your overall score. You need to achieve a minimum of Level 4 in all six criteria to achieve ICAO compliance.
Is RELTA endorsed in every country?
ICAO determines that every state has the sovereign right to nominate which test centres and which tests they endorse. You need to ask the civil aviation authority (CAA) of whichever state you wish your test results to be endorsed by for this information, and then follow the test centre’s requirements.
You can assume that the CAA of any country where RELTA is delivered has endorsed the test for that country. However, you cannot assume that another country will automatically endorse your RELTA test results.
For how long is an English language proficiency test score valid?
Your local civil aviation authority determines how long your test score remains valid.
ICAO recommends that:
- Level 4 is valid for licence endorsement for 3 years from the test date
- Level 5 is valid for licence endorsement for 6 years from the test date
- Level 6 is valid for licence endorsement for an indefinite period from the test date.
