What does the signal "CLEARED" indicate to a pilot?

The signal "CLEARED" indicates to a pilot that they have received authorization to proceed with a specific action, such as takeoff, landing, or taxiing. This instruction is an important part of air traffic control communications, signifying that all necessary safety checks are in place and that the pilot can safely continue with their flight operations. The term conveys that the pilot can execute the desired maneuver without delay, while also ensuring that they maintain situational awareness and comply with any additional instructions given by air traffic control.

The other options presented do not align with the meaning of "CLEARED." Being told to remain on standby implies that the pilot is not yet authorized to proceed. A canceled flight plan indicates a complete change of status, which is not what "CLEARED" communicates. The instruction to contact another frequency suggests a transition in communication rather than authorization to proceed. Thus, "CLEARED" is firmly associated with giving the pilot the green light to move forward with their intended action.
