The ICAO English Language Proficiency Rating Scale Applied to Enroute Voice Communication of U.S. and Foreign Pilots
|
|
|
|
In: DTIC (2009)
|
|
Abstract:
This is the third and final report in a series that examined communications between pilots and air traffic controllers during en route operations. The first report examined message complexity and message length as factors associated with communication problems (e.g., readback errors (RBEs), requests for repeats (RfR), and breakdowns in communication (BIC). The second report examined these same communication problems by differentiating between pilots flying U.S. - and foreign-registry aircraft. Aircraft call signs were used to classify transmissions by aircraft registry (U.S.-English, Foreign-English, Foreign-Other). Language proficiency was identified as a factor for 66/90 (73%) communication problems among foreign aircraft and for 56/191 (29%) involving U.S. aircraft. However, there was no mention of the level of proficiency among these pilots. This report examined the language proficiency among these controllers and pilots by applying the International Civil Aviation Organization (ICAO) language proficiency scales to the messages of pilots flying U.S. - and foreign-registry aircraft. The previously identified communication problems were re-examined and rated according to ICAO's six dimensions of language proficiency (pronunciation, structure, vocabulary, fluency, comprehension, interaction) by a certified rater. Each dimension receives a grade ranging from 1 (Pre-Elementary) through 6 (Expert). Approximately 94% of the pilots received an overall language proficiency rating (LPR) of 5 (Extended) because one or more of their utterances was graded Extended. The remaining 13 pilots' LPR was 4 (Operational), 12 of whom flew Foreign-Other registry aircraft. Among U.S. English communication problems, 50% were RBEs, and 33% were RfR. Foreign-Other communication problems were 57% RfR, 44% of which were made by pilots with an overall rating of Extended. ; Prepared in cooperation with Xyant Technologies, Inc., Norman, OK.
