Which of the following is NOT included in a standard METAR report?

A standard METAR report provides essential weather information for aviation, and it typically includes data such as wind direction and speed, visibility, and cloud cover along with any significant weather phenomena. The report is structured to give pilots and air traffic control a snapshot of current weather conditions at an airport.

Flight delays, however, are not part of the METAR report. Flight delays are operational factors that involve scheduling and logistics, which are reported and managed separately from the METAR weather conditions. Thus, the inclusion of flight delays would be outside the intended scope of a METAR report, focusing primarily on precise weather observations critical for flight safety and operations.
