Language Proficiency Tests

Pilots are required to prove their ability to communicate effectively in aviation radio telephony, encompassing both understanding and speech. This is evaluated through a proficiency test divided into three levels, with varying durations of validity, starting from four years. The initial test must be taken at a designated examination center, while renewals can occur through a flight assessment, provided the previous certification is still valid.

• Pilots must show proficiency in aviation languages for effective communication.
• The proficiency test has three levels, each with different validity periods.
• Initial tests are conducted at specific centers; renewals can be done during flights if valid.
