(2) ATM - Co-ordination & Transfer Of Control Flashcards
What is Co-ordination? (2)
- EU:
The process, executed between ATC units with adjoining areas of responsibility, of formally advising each other of the planned passage of flights across the boundary, in order to ensure flight safety through consistency of intended actions
- UK:
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 stages of transfer of control? (4)
- Notification of the flight
- Coordination of conditions by the transferring ATCU
- Acceptance of conditions of transfer of control by the accepting ATCU
- Transfer of control to the accepting ATCU or control sector
What should ATCU’s establish and apply standardised procedures towards, for the coordination and transfer of control of flights? (2)
Coordination procedures shall conform to the procedures contained in the following provisions and be specified in:
- LoA’s
- Local instructions
What should agreements & instructions cover? (13)
- Definition of areas of responsibility and common interest, airspace structure and airspace classification(s)
- Any delegation of responsibility for the provision of ATS
- Procedures for the exchange of flight plan and control data, including use of automated and/or verbal coordination messages
- Means of communication
- Requirements and procedures for approval requests
- Significant points, levels or times for transfer of control
- Significant points, levels or times for transfer of communication
- Conditions applicable to the transfer and acceptance of control, such as specified altitudes / flight levels, specific separation minima or spacing to be established at the time of transfer, and the use of automation
- ATS surveillance system coordination procedures
- SSR code assignment procedures
- Procedures for departing traffic
- Designated holding fixes and procedures for arriving traffic
- Applicable contingency procedures
- Any other provisions or information relevant to the coordination and transfer of control of flights
What shall ATC units shall forward from unit to unit, as the flight progresses? (2)
The necessary…
- Flight plan info
- Control information
In order to optimise ATS provision, when it is recommended that Transfer of Communication takes place before? (1)
Transfer of Control at a point/time/distance agreed upon between the transferring and accepting ATSUs
Transfer of communication is the same as Transfer of control.
True or False?
False
When should a transfer of control of an aircraft happen from the ATC unit to the next unit? (1)
At the time of crossing the common control area boundary as determined by the unit having control of the aircraft or at such other point or time as has been agreed between the two units
When should the responsibility of a transferred aircraft happen to a receiving ATC unit? (1)
Responsibility for control shall not be assumed until the time of crossing the control area boundary or other transfer of control point specified in letters of agreement between the ATC units
Where should transfer of control take place once co-ordination has been reached / agreed? (4)
- Agreed Reporting Point
- On estimate for FIR boundary
- At or passing agreed level
- Climbing or descending to agreed level – providing standard separation exists
If the flying time from the departure aerodrome of an aircraft to the boundary of an adjacent control area is less than the specified minimum required to transmit flight plan and control information to the accepting ATC unit, the transferring ATC unit shall, prior to departure, forward that information to the accepting ATC unit together with a request for approval. True or False?
True
Read the lesson on all the different Co-ordination types and criteria Slides 16-29
What shall the means of coordination shall be dependent upon? (5)
- The availability of adequate communications channels
- The functions to be performed
- The types of data to be exchanged
- The letters of agreement
- The processing facilities at the centres concerned
What possible means of communication are available? (4)
- Direct speech circuits
- Aeronautical Fixed Telecommunication Network (AFTN)
- Digital data exchange between ATS units
- Direct computer-computer circuits
