Coordination and Transfer of Control Flashcards
Describe Coordination in EU Terms
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
Describe Coordination in UK Terms
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?
a) Notification of the flight in order to prepare for coordination
b) Coordination of conditions of transfer of control by the transferring ATCU
c) Acceptance of conditions of transfer of control by the accepting ATCU
d) the transfer of control to the accepting ATCU
What should standardised coordination procedures include?
a) Definition of areas of responsibility, airspace structure and airspace classification
b) Any delegation of responsibility for the provision of ATS
c) Procedures for the exchange of flight plan and control data
d) Means of communication
e) Requirements and procedures for approval requests
f) Significant points, levels or times for transfer of control
g) Significant points, levels or times for transfer of communication
h) Conditions applicable to the transfer and acceptance of control
i) ATS surveillance system coordination procedures
j) SSR code assignment procedures
k) Procedures for departing traffic
i) Designated holding fixes and procedures for
arriving traffic
m) Applicable contingency procedures
n) Anything else relevant
What should take place first, transfer of control or communication?
It is recommended that Transfer of Communication takes place before Transfer of Control at a point/time/distance agreed upon between the transferring and accepting ATSUs
When does Transfer of Control occur?
The responsibility for the control of an aircraft shall not be assumed until the time of crossing the common control area boundary or at such other point that has been agreed
Where can Transfer of control take place?
Agreed Reporting Point
Estimate for FIR Boundary
At or passing agreed level
Climbing or Descending to agreed level
Can an ACC release aircraft directly to tower, skipping approach?
Yes. After coordination with approach, ACC can release aircraft directly to aerodrome control towers if the entire approach will be made under VMC.
When is a take-off time specified by ACC?
When it is necessary to
a) Coordinate the departure with traffic not yet released to approach
b) Provide en-route separation between departing aircraft following the same track
What does approach keep ACC advised of?
a) Runway in use and type of approach
b) Lowest vacant level at holding fix available for use by ACC
c) Average time or distance between successive arrivals
d) Revision of EAT if it differs by 5 minutes or any other agreed time
e) Arrival times over the holding fix that vary by three minutes compared to the estimate
f) Cancellation of IFR flights, if it would affect holding fixes or EATs
g) Aircraft departure times
h) All information relating to overdue or unreported aircraft
i) Missed approaches which affect the ACC
What does ACC keep approach advised of?
a) Ident, type and origin of arriving aircraft
b) Estimated time and proposed level of arriving aircraft over any specified point
c) Actual time and proposed level of arriving aircraft that have passed the holding fix
d) Aircraft requested approach if different from the one approach is offering
e) Issued EAT
f) A statement that aircraft has been transferred, if required
g) A Statement that aircraft has been released, if required
h) Anticipated delay of departing traffic due congestion
When should information on arriving aircraft be forwarded from ACC to Approach?
Information on arriving aircraft shall be forwarded from ACC to approach not less than fifteen minutes before estimated time of arrival.
When is control of arriving aircraft transferred between approach and aerodrome?
Approach shall retain control of arriving aircraft until such aircraft have been transferred to the aerodrome control tower and are in communication with.
Can approach authorise tower to release an aircraft for takeoff against an arrival subject to the disretion of tower?
Yes, it is towers responsibility to ensure separation between the two aircraft
What does approach keep tower advised of?
a) ETA and proposed level of arrivals, at least 15 minutes before ETA
b) A statement that an aircraft has been transferred, if required
c) Anticipated delay to departing traffic due to congestion
