What word should not be used in conjunction with authorized for aircraft to taxi?

Using the term "cleared" in conjunction with authorized for aircraft to taxi is not appropriate because in air traffic control terminology, "cleared" is a specific phrase that indicates official permission for a pilot to proceed with a particular action, such as takeoff, landing, or to enter controlled airspace. When it comes to taxying, the phrase "taxi authorization" or "taxiing authorized" is used without the term "cleared." This distinction is important for maintaining clarity and adherence to standard phraseology in aviation communication, which ensures safety and reduces the risk of misunderstandings.

In contrast, terms like "confirmed," "allowed," and "granted" can appropriately accompany "authorized" as they convey that permission has been given without being ambiguous. These terms can reinforce the message that the aircraft is allowed to taxi based on the situation outlined by air traffic control. Thus, it is crucial to use precise language in operational communications, and "cleared" does not align with the terminology used for taxi authorization.
