Markings must be placed so that no part of the marking is obscured and should be durable, legible, and in which language?

• A. English
• B. French
• C. Spanish
• D. German

Answer: (A)

In international aviation, markings are standardized to be understood by anyone involved in safety and operations worldwide. English is the language used for these markings because it is the universal aviation language recognized by ICAO. This ensures that pilots, air traffic controllers, maintenance crews, and ground staff from all countries can read critical safety information clearly and consistently, reducing the risk of misinterpretation in both everyday operations and emergencies. While local regulations may permit translations or additional labels in other languages, the primary language for markings remains English.
