Who do you typically call when making contacts related to the flight?

The best option focuses on the critical contacts necessary for coordinating a successful flight operation. When making contacts related to the flight, it is essential to inform the receiving facility about the expected arrival time, ensuring that all preparations are made for the incoming aircraft and patients if applicable. Security is a key aspect as well, ensuring safe handling of passengers and cargo at both departure and arrival locations. Additionally, contacting other airlines may be relevant for coordinating connections or addressing any operational needs that may arise.

The other options, while they contain some relevant contacts, do not encompass the most immediate and necessary contacts for operational management during flight-related activities. For example, while the weather service is important for flight planning, it does not directly impact the handling procedures at the destination. Ground services are also critical, but they are more relevant to the operational side of the flight rather than immediate contacts during the flight phases.
