What is the proper way to state an altitude of 14,700 feet?

The proper way to state an altitude of 14,700 feet in aviation communication is "One Four Thousand Seven Hundred." This format follows the guidelines established for clear and unambiguous communication in aviation.

When stating an altitude over the radio, clarity is crucial, especially in busy environments where miscommunication can lead to safety issues. The phrase "One Four Thousand Seven Hundred" effectively conveys the altitude in a way that is easily understood by air traffic control and other pilots. Breaking the number into sections avoids confusion that could arise from overpronouncing or abbreviating numbers.

The first part, "One," clearly indicates that the altitude is above 10,000 feet, followed by "Four Thousand," which represents the thousands, and "Seven Hundred," representing the hundreds. This structure minimizes the risk of misinterpretation.

While the other options may seem like valid ways to represent the altitude, they either introduce unnecessary complexity or do not conform to standard procedures, which prioritize brevity and clarity for safety in communication.
