2.10 Practices and Rules

2.10.2 Demonstrate proficiency in transmitting and receiving spoken messages competently and in accordance with prescribed procedures, including

(a) language to be used;

In aviation, the International Civil Aviation Organization (ICAO) has established English as the standard language for aviation communication.

English is used as the common language because it ensures effective communication between pilots, air traffic controllers, and other aviation personnel from different countries and backgrounds.

It helps maintain a standardized level of understanding and reduces the potential for miscommunication.

Overall, the language used in aviation communication should be clear, concise, and adhere to standardised phraseology and procedures to ensure safe and efficient communication between all parties involved. 

Polite terminology such as 'please' and 'thank you' should be avoided.

(b) word spelling;
