Air Traffic Skills Assessment (ATSA) Practice Test

The correct way to state the radio frequency of 122.95 is "one two two point nine five." This format follows standard radio communication protocols, which emphasize clarity and quick understanding among pilots and air traffic controllers. The practice of stating frequencies in single digits, followed by "point," helps ensure that each number is clearly conveyed and reduces the chances of miscommunication, especially in noisy environments.

The choice to use single digit enumeration rather than stating the frequency as "one hundred twenty-two point nine five" may cause confusion, as it can be easy for listeners to mishear or misinterpret the figures due to their length. The notion of using "decimal" instead of "point" is also not standard in aviation communications, as "point" is the universally accepted term in this context. Lastly, stating "one hundred two point nine five" incorrectly refers to a different frequency entirely, illustrating the importance of accurately conveying the digits to avoid significant operational errors.
