What terms should be used for equipment/vehicles and personnel?

The term "proceed" is commonly used in air traffic control to instruct an aircraft to continue its movement, typically on the ground or in the air, without requiring immediate compliance with other instructions. Using this term ensures clarity and maintains the flow of communication between air traffic controllers and pilots, as it contains a directive and an expectation of action.

The phrase "hold" is also essential as it directs an aircraft or vehicle to stop its movement and maintain its position. This term is crucial for maintaining safety in situations where there may be potential conflicts with other aircraft or vehicles or when further instructions are pending.

Together, "proceed" and "hold" form a clear and effective set of instructions that enhances situational awareness and ensures that all parties understand their movements within the controlled airspace. This terminology fosters the safe and orderly flow of traffic, which is a primary objective of air traffic control operations.
