CATCC shall ensure a ship's weather observation will be taken at least every ________ minutes during flight operations.

Weather data must be updated regularly during flight operations to keep flight decisions aligned with current conditions. The interval of 45 minutes provides timely updates to reflect changes in sea and sky conditions while remaining practical for the ship’s watch teams. Taking observations more often, such as every 15 or 30 minutes, would increase workload during busy flight operations, whereas waiting 60 minutes could allow weather changes to outpace safety needs. A weather observation typically includes wind speed and direction, visibility, ceiling, significant weather, and altimeter, all of which feed into flight planning, approach and departure decisions, and deck operations. Therefore, 45 minutes is the most appropriate interval.
