The proper phraseology for stating altitude to ATC is essential for clarity and effective communication. The phrase "ONE ZERO THOUSAND, FIVE HUNDRED" effectively conveys the altitude of 10,500 feet MSL by breaking it down into a format that minimizes potential misunderstandings.

In aviation communication, altitudes are typically expressed in thousands and hundreds. By saying "ONE ZERO THOUSAND," the pilot confirms the thousands, and "FIVE HUNDRED" distinctly represents the additional five hundred feet. This method is in line with regulatory standards that emphasize clarity and precision in air traffic communications.

Additionally, the other options present formulations that could lead to confusion or lack the necessary specificity. For example, "TEN THOUSAND AND FIVE HUNDRED" may not be as clear to all listeners, particularly in a high-traffic environment. "ONE THOUSAND, FIVE HUNDRED ZEROS" inaccurately implies a vastly different altitude, and "TEN FIVE ZERO ZERO" does not use the standard format, potentially leading to misinterpretation. Using the correct format is key to ensuring all parties have the same understanding, particularly in dynamic air traffic situations.
