ADDITIONAL SERVICES - Pilot/Controller Glossary

📢 This glossary was originallly created to be a dynamic version of the Pilot/Controller Glossary published by the FAA. Because the FAA now maintains its own dynamic version of the Pilot/Controller Glossary, this version is no longer updated.

Term:	ADDITIONAL SERVICES
Meaning:	Advisory information provided by ATC which includes but is not limited to the following: Traffic advisories. Vectors, when requested by the pilot, to assist aircraft receiving traffic advisories to avoid observed traffic. Altitude deviation information of 300 feet or more from an assigned altitude as observed on a verified (reading correctly) automatic altitude readout (Mode C). Advisories that traffic is no longer a factor. Weather and chaff information. Weather assistance. Bird activity information. Holding pattern surveillance. Additional services are provided to the extent possible contingent only upon the controller's capability to fit them into the performance of higher priority duties and on the basis of limitations of the radar, volume of traffic, frequency congestion, and controller workload. The controller has complete discretion for determining if he/she is able to provide or continue to provide a service in a particular case. The controller's reason not to provide or continue to provide a service in a particular case is not subject to question by the pilot and need not be made known to him/her.
