Answer :
Final answer:
The phrase "Cleared across the runway" is not approved for instructing aircraft, vehicles, equipment, or personnel to cross or operate on a runway due to its lack of specificity and potential to cause misunderstandings. Standardized phraseology such as "Cross the runway" or "Taxi across the runway" is preferred for clarity and safety in aviation communications.
Explanation:
The question relates to the specific phraseology approved for instructing aircraft, vehicles, equipment, or personnel to cross or operate on a runway. The correct choice and the phraseology not approved is D) "Cleared across the runway." This is because the term "cleared across the runway" lacks the specificity and clarity often required in aviation communications. In aviation, precise and unambiguous communication is critical for safety. Phrases like "Cross the runway," "Taxi across the runway," and "Enter the runway" are more commonly used and approved because they provide explicit instructions. "Cleared across the runway," on the other hand, could imply a variety of actions and thus is not preferred.
It is essential for all personnel involved in aviation to use standardized phraseology to avoid misunderstandings that could lead to safety incidents. The International Civil Aviation Organization (ICAO) and other regulatory bodies have developed specific phraseology guidelines to enhance clarity in communication.
