Aviation English Research Project: Data analysis findings and best practice recommendations

2. Aviation English
A specialized code, based on the English language, used by pilots and air traffic controllers working in international civil aviation, and having standards, phrases, and levels of proficiency established by ICAO.

3. Language Proficiency Requirements (LPRs)
The set of six language proficiency skills set out in ICAO (2010) with which all pilots and controllers working in international civil aviation must comply. The six skills are Pronunciation, Structure, Vocabulary, Fluency, Comprehension, and Interactions. Pilots and controllers working in international civil aviation must demonstrate proficiency to a minimum Operational Level 4.

5. Moder and Halleck (2009) note that only the ICAO LPR descriptors for vocabulary and comprehension refer to work-related topics; other descriptors refer only to general purpose proficiency.

6. Moder and Halleck (2009) note ‘by relying on the rating scales alone, we are more likely to focus on general English proficiency’.

7. Plain English
The spontaneous, creative, and non-coded use of English, especially as used in the aviation context to contrast with specialized code of aviation English.

8. Key Problems in ATCO-Pilot Communications
Readback - hearback errors (by both native and non-native pilots and controllers);

9. Key Problems in ATCO-Pilot Communications
Call sign confusion (by both UK and non-UK pilots and controllers);

10. Key Problems in ATCO-Pilot Communications
Language proficiency below ICAO minimum standard (non-native pilots and controllers)

11. Key Problems in ATCO-Pilot Communications
Situational awareness reduced due to multilingual radiotelephony (RT)

12. Key Problems in ATCO-Pilot Communications
Non-standard phraseology use (by both native and non-native English speakers);

13. Key Problems in ATCO-Pilot Communications
Grounds to suspect cheating on aviation English exams

14. Key Problems in ATCO-Pilot Communications
Grounds to suspect that some non-native English speakers are not being tested, but instead are granted ICAO Level 4 certificates on ‘sweetheart’ deals
Social and cultural norms of saving ‘face’ and showing respect
An attitude widely encountered and accepted (though rarely documented) is that language-related miscommunication is not a significant risk to aviation safety

15. Key Problems in ATCO-Pilot Communications
ICAO levels of language proficiency, especially Level 4, are not robust enough to ensure appropriately clear pilot / controller communication;

16. Key Problems in ATCO-Pilot Communications
Poor Safety Reports / language-related reporting culture and underreporting of language proficiency issues by pilots and controllers.

17. All limitations of qualitative research
Limitations and Delimitations
All limitations of qualitative research
Spoken data requires transcription, which is time-consuming.

18. Limitations and Delimitations
confidentiality

19. Limitations and Delimitations
Lack of detail in language- related Safety Reports
(e.g. poor language proficiency, speech rate, non-adherence to ICAO phraseology, accents)

20. Limitations and Delimitations
Lack of original data, e.g. interviews with pilots and controllers, observation

21. Limitations and Delimitations
Most existing research on pilot / controller communication is done from a US point of view, by US-based researchers, or with US interests in mind.
There is little research available in English with a non-native English-speaking focus.

22. Some research areas
Accents (Accent affects clear and concise communication between pilots and controllers)
Code-switching and bilingualism in radiotelephony (practice of speaking local languages alongside English in international radiotelephony is in keeping with ICAO procedures. )
Complexity and length of controller messages
Numbers (call sign confusion and flight level confusion e.g. FL260 / FL360; UAE1 / UAE9)
Speech rate
