Which of the following would NOT typically be noted in candidates' remarks?

In the context of candidates' remarks, signal strength is generally not a critical factor that is recorded or communicated in standard operating procedures for radar operations. Candidates’ remarks primarily focus on operational parameters that are crucial to flight safety and management, such as flight altitudes, fuel status, and indications of communication failure (like NORDO, which stands for "no radio").

Flight altitudes are significant because they inform the operational altitude of aircraft, which is essential for safety and air traffic management. FUEL status is crucial as it indicates the amount of fuel available for a flight, which can directly affect the flight's operation and safety. NORDO indications are equally important as they signal when an aircraft is unable to communicate, necessitating immediate attention and alternative procedures.

While signal strength may be relevant to the technical performance of radar itself or the quality of communication, it is not typically included in pilots' or air traffic controllers' remarks as it does not directly impact flight safety or operational decisions. Thus, this understanding clarifies why signal strength is not a typical element in candidates' remarks.
