The correct method of stating 4,500 feet Mean Sea Level (MSL) to Air Traffic Control (ATC) is to say "FOUR THOUSAND FIVE HUNDRED." This phraseology adheres to the standards set by aviation communication protocols, ensuring clarity and reducing the potential for misunderstandings.

When communicating altitude to ATC, it is essential to use a format that is easily understood. Stating "FOUR THOUSAND FIVE HUNDRED" eliminates any ambiguity by clearly articulating the numbers without any interruptions or extra words that could confuse the listener. This method of communication is particularly important given the critical nature of altitude information in maintaining aircraft safety and avoiding miscommunication during flight operations.

Other phrasings would not provide the same level of clarity. For instance, saying "FOUR FIVE ZERO ZERO" emphasizes individual digits, which can lead to confusion especially in radio communications where clarity is paramount. Similarly, “FOUR THOUSAND, FIFTY” and "FOUR THOUSAND AND FIVE HUNDRED" either misrepresent the altitude or introduce unnecessary complexity that is not standard practice.

Overall, using "FOUR THOUSAND FIVE HUNDRED" aligns with the expected practices in aviation communication, ensuring
