In the past incidents and accidents originated from language difficulties between pilots and controllers resulting in communication problems with sometimes terrible consequences. To improve the level of English used by air traffic controllers and pilots, ICAO introduced the Language Proficiency Endorsement test (LPE).
This test establishes a certain level of Aviation English where level 4 is needed as an operational minimum. Below you will find the requirements for this test. Contact your authorities for details on where to take the test.
English Aviation Language
How strange it may seem, the test is also required for native English speakers. Section 3.2.1 of ICAO Doc 9835-AN/453 says: "The ICAO language proficiency requirements apply to native and non-native speakers alike. As English is the most commonly used language for international aviation communications, many non-native speakers of English will require language training to improve their language proficiency. Nonetheless, the burden for improved communications should not be seen as falling solely on non-native speakers. Native speakers of English, too, have a fundamentally important role to play in the international efforts to increase communication safety, and much of the information contained in this chapter is aimed at native speakers interacting with non-native speakers.".
So, we as pilots and controllers all have to do this test. One small advantage for native English speakers and those fluent in English as a second language, is that they will have to do this test probably only once.
The test itself isn't that difficult and consists of two parts. One is a listening part were you need to answer questions based on a radio conversation between an aircraft and ATC and the second part is an interview where the examiner(s) interacts with you on aviation subjects. Both tests should take each about thirty minutes. Good luck!
The table below shows all levels and requirements needed to pass the test.
Do not forget to have this rating added onto your license!
ICAO stated that LPE-4 is valid for three (3) years, LPE-5 for six (6) years and level 6 is valid forever and no further assessment is necessary.
