In aviation communication, what does "patter" refer to?

In aviation communication, "patter" refers to a routine transmission of critical information. This term is often used to describe the standardized and repetitive nature of certain flight-related communications, such as routine weather announcements, ATIS broadcasts, or pre-flight check-in procedures. These transmissions are designed to convey essential information efficiently and clearly to all pilots and air traffic control, ensuring safety and maintaining effective communication.

The use of patter helps minimize miscommunication and makes it easier for pilots to absorb vital updates without confusion. Such routine transmissions often follow a specific format, enabling pilots to quickly identify key information amidst a busy communication environment. This is particularly important in high-density airspace or during peak operational hours when clarity can significantly impact safety and operational efficiency.
