What additional services are provided when the work situation permits?

The designation of "Additional Services" aligns perfectly with the context of air traffic control operations, where controllers are often able to offer various extra assistance beyond their fundamental responsibilities when conditions allow. These services can include things like weather updates, traffic advisories, and other support based on the specific needs of pilots and aircraft.

While emergency services and search and rescue are critical components of air traffic operations, they are typically initiated under specific circumstances rather than as routine additional services. Pilot briefings are more focused on providing information to pilots before they leave the ground rather than ongoing support during flight. Thus, "Additional Services" embodies the concept of voluntary extra support that stretch beyond the standard air traffic control functions, contingent upon the work environment and situation at hand.
