ATM Flashcards
Basic Service
• Is a type of UK FIS provided for the purpose of giving advice and information useful for the
safe and efficient conduct of flight? This may include weather information, changes of
serviceability of facilities, conditions at aerodromes, general airspace activity information,
and any other information likely to affect safety. The avoidance of other traffic is solely the
pilot’s responsibility
Traffic Service
• Is a surveillance-based type of UK FIS where, in addition to the provisions of Basic Service,
the controller provides specific surveillance-derived traffic information to assist the pilot in
avoiding other traffic. Controllers may provide headings and/or levels for the purposes of
positioning and/or sequencing; however, the controller is not required to achieve
deconfliction minima, and the pilot remains responsible for collision avoidance.
Deconfliction Service
• Is a surveillance-based type of UK FIS where, in addition to the provisions of Basic Service,
the controller provides specific surveillance-derived traffic information and allocates
headings and/or levels to fly aimed at achieving planned deconfliction minima, or for
positioning and/or sequencing. Nevertheless, the avoidance of other traffic remains the
pilot’s responsibility.
Procedural Service
• Is an ATS where, in addition to the provisions of Basic Service, the controller provides
restrictions, instructions, and approach clearances, which if complied with, will achieve
deconfliction minima against other aircraft participating in the Procedural Service. Neither
traffic information nor deconfliction advice can be passed with respect to unknown traffic.
What is an alerting service?
• A service provided to notify appropriate organisations regarding aircraft in need of SAR aid
and assist such organisations as required.
Define Coordination
• The act of negotiation between two or more parties each vested with the authority to make
executive decisions appropriate to the task being discharged.
What are the weights for the Wake Turbulence Categories?
• H - 136,000kg or more
• UM - <136,000kg but >104,000kg
• LM - <104,000kg but >40,000kg
• S - <40,000kg but >17,000kg
• L - <17,000kg
Define Coordination
The act of negotiation between two or more parties
each vested with the authority to make executive
decisions appropriate to the task being discharged.
Effected when the parties concerned, on the basis
of known intelligence, agree a course of action.
Responsibility for obtaining and ensuring
implementation may be vested in one of the ATCOs.
Tactical Co-ordination
For individual aircraft provided with, or are about to be provided with, an ATS. Achieved either verbally (face-to-face or over a landline) or silently using an electronic aid.
Standing Co-ordination
Co-ordination which is implemented automatically, on a permanent basis, without communication between the controllers involved. (Achieved by written agreement, and is only valid for those aircraft and circumstances specified in MATS Pt 2)
When does transfer of control take place?
Achieved when a flight operating in accordance
with the co-ordination has reached agreed
position or level.
- Takes place at:
- Agreed Reporting Point.
- On estimate for FIR boundary.
- At or passing agreed level.
- Climbing or descending to agreed level -
standard separation exists.
Transfer of control
Permitted so that instructions which become
effective later can be issued.
MATS PT1 SEC1 CH4

Flight priorities
What are other flights? (Z)
Pipeline / power line surveys
Usually flown low level by helicopter, be aware
of pylons in vicinity of ATZ as flights will follow
these and often contact Aerodrome Control.
Aerial Photography
Very common overhead towns, cities,
landmarks, river estuaries.
Will operate for up to an hour in the vicinity,
often on final approach!
