How is the RNAV Route Q142 pronounced?

The correct pronunciation of the RNAV Route Q142 is "Route Q One Forty Two." This is a standard practice in aviation where flight routes that include letters and numbers are pronounced clearly to avoid any misunderstanding.

In this case, the letter 'Q' is simply pronounced as its letter name, followed by the numbers '1', '4', and '2,' which are stated individually and in sequence as "One Forty Two." This method of enunciation minimizes the chances of any miscommunication between pilots and air traffic control, which is crucial for maintaining safety in aviation operations.

The other choices present varying interpretations of the route's designation but do not adhere to the established convention of pronouncing route identifiers. Thus, while they may seem creative or humorous, they do not reflect the standard practices used in air navigational communication.
