When is it crucial to provide special handling for flight check aircraft?

Providing special handling for flight check aircraft is crucial primarily when there is a need to expedite their progress. Flight check aircraft usually perform necessary inspections and checks to ensure safety and adherence to regulations, and these operations can be time-sensitive. When flight check aircraft require expedited routing or handling, it is essential for maintaining operational efficiency and safety in the airspace.

In other scenarios, such as during busy traffic periods or when other aircraft are involved, standard handling procedures may suffice, as the prioritization of flight check aircraft is not solely dependent on those factors. Special handling should focus on the need for efficiency and timely completion of their missions, as they may have limited time to execute their tasks.
