What is the Planning Controller responsible for?
The Planner is responsible for issuing Oceanic clearances and coordination where appropriate for all aircraft entering the Shanwick OCA from a domestic centre, including eastbound flights entering/transiting from Madrid.
For flights routeing on T9/T213 in either direction, the Planner is not required to coordinate a clearance at an enroute level with the Enroute controller if there are no conflicts or warnings shown to the Planner when clearing the flight.
The Planner is also responsible for approving eastbound flights that do not comply with FLAS.
Responsibility for updating these flights shall be delegated to the Enroute controller with jurisdiction over the requested flight level.
What is the Enroute Controller responsible for?
Enroute controllers are responsible for the provision of Air Traffic Control, Flight Information and Alerting Services at and above FL55, in addition to providing Flight Information and Alerting Service to all known traffic below FL55.
The Enroute controller is responsible for approving flights entering Shanwick from another OCA, both eastbound and westbound except those originating at RATSU. Coordination with the Planner may be necessary for those flights close to the Shanwick eastern boundary.
Detail the authorised use of MANCL list.
Resolve a conflict where separation between aircraft has been eroded.
Opposite direction aircraft east of the OCA boundary where coordination has been effected.
Aircraft in emergency during descent, return or diversion where the path is in conflict.
Resolve a conflict involving flights on Round Robins, return legs or turnbacks, where an offset coordinate has been input in GAATS+, but the flight has been cleared using whole degrees i.e. flight cleared on 56N but coordinate 5601N is input in GAATS+.
If a conflict occurs wholly within an adjacent sector and they state that the conflict will be resolved by the use of radar control or other means.
Flights operating as part of the same reservation.
Two or more conflicting reservations which have been approved subject to MARSA.
When applying UK OPCON procedures.
Apply reduced MNPS separation standards between MNPS aircraft and Stationary Reservations, outside MNPS airspace.
Two or more non-MARSA reservations, where erroneous conflicts are generated in GAATS+ due to overprotection of complex flight profiles, provided that the controller has ensured that sufficient level/route separation exists between all flights.
List the contents of a POS report.
Each Position Report will contain:
Aircraft’s position
Reported time at that position
Current Flight Level

When is a POS report considered non-conformant?
Position reports are considered to be ‘non-conformant’ if:
Incorrect position is reported
Incorrect flight level is
reported
Incorrect next or subsequent position
Reported time differs by more than 2 minutes
The ETA for next position differs by more than 5 minutes
In these instances the controller shall ask the aircraft to confirm the position report or the specific item of data that was not as expected.
When a position report is received where the next reporting point is incorrect, controllers shall immediately confirm the correct routeing with the flight.
Explain what GNEs, Lateral Deviation, Intervention and Prevention are.
A Gross Navigation Error is a lateral deviation from a cleared track by 10nm or more.
A Lateral Deviation is any actual deviation from the cleared track other than those covered by Strategic Lateral Offset Procedures.
An ATC Intervention is an event where the ATCO caught and corrected a lateral deviation before it developed into a GNE.
An ATC Prevention is an event where ATCO action prevented a lateral deviation.
Explain the Gentle Slope Rule.

When FL250 is used for the transit leg to a UK OPCON area, how does the captain obtain an oceanic clearance?
Call on the CDO frequency 30 minutes before the ETA at the Shanwick boundary or ASAP thereafter to confirm time at the boundary and obtain clearance.
15 minutes before the ETA for the descent point, Captain confirms his ETA and requests information on all traffic affecting descent. At descent point, Captain will message: “Descending and going operational”.
Regarding UK OPCON areas, who is responsible for separation below FL240?
The Captain of the operational aircraft.
Do you pass traffic information on aircraft flying within 60nm of an OPCON area?
Yes, as well as those flying within it.
Regarding descending into or climbing out of a UK OPCON area, who is responsible for the separation between FL250 and FL270 inclusive?
The Captain is responsible. Shanwick advises the aircraft of any traffic affecting it at these levels. When the aircraft reaches the cleared FL or passes FL280, Shanwick regains control.
What is Due Regard?
Used by military aircraft, Due Regard allows the military aircraft commander to be his own ATC agency and separate his aircraft from all other traffic.
Military aircraft operating under Due Regard are subject to one or more of the following conditions:
Aircraft shall be operated in VMC.
Aircraft operating within radar surveillance and radio communication of surface radar facility.
Aircraft equipped with airborne radar sufficient to provide themselves with separation from other aircraft.
Aircraft operated outside controlled airspace.
What two types of reservation are there and what are they for?
Stationary.
Moving.
Stationary - Sterilising a piece of airspace within prescribed lateral and vertical limits that do not change with time.
Moving - A reservation to protect a particular route and levels that follow an aircraft’s flight through Shanwick.
Between Stationary Reservations and other aircraft, what are the lateral separation minima?
For NAT HLA equipped aircraft:
30nm provided the operating agency has guaranteed that the reservation activity will be confined to the reservation.
60nm if no guarantee has been given.
The above can be applied to aircraft or moving reservations against the stationary reservation, provided that one of the moving reservation aircraft meets NAT HLA requirements.
For non - NAT HLA equipped aircraft:
60nm provided the operating agency has guaranteed that the reservation activity will be confined to the reservation.
120nm if no guarantee has been given.
Between Stationary Reservations and other Stationary Reservations, what are the lateral separation minima?
60nm provided the operating agency has guaranteed that the reservation activity will be confined to the reservation.
120nm if no guarantee has been given.
These rules do not apply if both sponsors are aware of the activity of the other. E.g. UK OPCON areas overlapping HSF.
Between Moving Reservations and other Moving Reservations, what are the lateral separation minima?
60nm against NAT HLA equipped aircraft within a reservation.
120nm against non - NAT HLA aircraft.
In the case of formation flights, only one aircraft is required to meet NAT HLA standards.
What is MARSA and when is it used?
Military Assumes Responsibility for Separation of Aircraft.
It is the delegation of separation of aircraft in flight to military authorities.
Used when military aircraft must operate in close proximity.
Often used within Oceanic Reservations.

Approval Void for Aircraft Not Airbourne.
It is a time at which the approval is void if the aircraft in question has not taken off.
What is the maximum number of waypoints that a reservation between FL290 and FL410 can have?
No more than 15.
What are the Enroute controller responsibilities regarding flights within a reservation?
On request, provide a FIS.
On request, provide an Alerting Service
Maintain standard separation against traffic outside the reservation.
Confirm that adjacent ATSUs are aware of all reservations which would enter their AOR.
This usually involves coordinating the number of aircraft, types of aircraft and which are in contact with ATC.
What are the ADS-B special codes and their associated meanings?
General Emergency - EMR Medical Emergency - MED Minimum Fuel - GAS No Comms - RDO Unlawful Interference - HIJ
What happens if the Nav Canada Gateway fails and will pilots be aware of the failure?
We lose ADS-C and CPDLC but the pilots will not necessarily be aware.
If Aireon goes down, what happens?
We get no ADS-B data and therefore cannot apply ASEPS.
There is an audible alarm that says SDP link lost, also on GDD.
If Fusion is online but the Fusion Line is down, there will be no warning to the controller.
What is MRTS and what does it do?
Manual Reversion Transition System.
In addition to the strips displayed on the sector at the time of failure, MRTS will print strips that would have been eligible for display.
In the case of FANS failure, controllers endeavour to establish a standard separation between flights, but in the event of multiple FANS failures, what are the controller actions?
CANCEL ALL CONTRACTS in the ADS window with flights that do not require ADS-C for separation, thus reducing the excessive failure messages.
Board check to clarify which flights are using ADS-C separations and consider cancelling contracts with these flights also.
If flights are Westbound requiring ADS-C separations and they are East of 20W, instruct the flight to log on to CZQX without logging off of Shanwick.
If flights are Westbound requiring ADS-C separations and they are West of 20W, co-ordinate them with Gander
Inform Gander of the failure.
Request Gander monitors the Eastbound flights through our airspace if possible.
Do not clear using ADS-C separations.
Use HF to advise flights using ADS-C separations to make voice reports.
How do we record hard copies of POS reports received during MO?
Tick crossed out = Correct position reported.
Tick = Next position is correct.
Dot = Subsequent position is correct,
Add a diagonal slash line under the position to record the estimates and reported times.
Forward estimates are entered above the line, reported times are entered below the line.
During MO, what type of reports will be delivered to the controller?
Only Waypoint Reports will be delivered in the interest of saving time.
During MO, reduced separations are no longer applicable. The controller should check strips for flights separated by 5 minutes or less at landfall where the second aircraft is the same speed or faster. In these circumstances, what are the controller actions?
On HF, instruct flight to report any changes in speed, level or route. Issue Essential Traffic Information.
Consider increasing longitudinal spacing through Mach number clearances.
Consider issuing ATB/ATA restrictions for the next waypoint.
Advise Gander of the failure and request they provide additional monitoring of reduced separations prior to 30W. Update Manual Strip Display to indicate any flight Gander agree to provide additional monitoring.
GAATS+ sends and receives data on all flights operating at what levels?
All flights above FL50.
Regarding time revisions, how many minutes does an aircraft have to be out for us to advise adjacent sectors?

Narsarsuaq. It appears as NA on the GDD.
What do you do on receipt of a MAC message and who can we send MAC messages to?
Call the offering agency and confirm that the flight is no longer entering Shanwick.
We only send to CZQX and LPPO.
BIRD cannot accept.
Explain BET PC and what it does.
BET PC compares OCM and EFD.
It warns if:
Boundary estimate is not credible. (Differs by 20mins or more)
Aircraft is uncleared. (10mins / 15mins prior to boundary, if no OCM exists, warning message is output including aircraft’s last reported FL.)
Not at the cleared level. (Warning 2 mins from boundary if the flight is not within 1,200ft / 1,700ft.)
(Warning again 1 min frim boundary if the flight is not within 900ft.)
(Domestic, Shannon and Brest will have aircraft level 3 minutes prior to the boundary where possible.)
Name 3 LRNS.
GPS - Global Positioning System
INS - Inertial navigation System
GNSS - Global Navigation Satellite System
What is FOM?
Figure Of Merit.
