ATS Surveillance Standards Flashcards
According to MATS Part 1, what may surveillance systems be used to provide, whether or not the aircraft has been identified?
a) Information on the position of aircraft likely to constitute a hazard
b) Avoiding action
c) Information about observed weather for pilots and other controllers and
d) Assistance to aircraft in emergency
What do surveillance services comprise of?
a) Separation of arriving, departing and en-route traffic
b) Vectoring
c) Position information to assist in the navigation of aircraft
d) Monitoring traffic to provide information to the procedural controller
e) Assistance to aircraft crossing controlled airspace
What shall a controller do before providing any of the surveillance services, and what does this action not imply?
a) Identify the aircraft, using a method appropriate to the surveillance system in use, or
b) Have had the identity of the aircraft transferred from another controller
The act of identifying an aircraft does not imply that a service is being given.
As described in MATS Part 1, when is it NOT necessary to inform the pilot of an aircraft that the identification of his aircraft has been lost?
When using SSR, controllers may be temporarily unable to read the data blocks associated with aircraft due to overlapping or garbling, eg. in holding areas. Although this constitutes a loss of identification, the pilot need not be advised that identification has been lost if the controller anticipates that identification will be re-established immediately the overlapping or garbling ceases.
