SAS646 receives its STAR from ATC
SAS646 arrives on Sweden Control frequency near MIKNA and
receive confirmation of its STAR [TRS2N] from ATC.
The STAR is entered in the FMS by the crew, which computes a
trajectory (non-time constrained), which is refined with a wind uplink.
A new trajectory is then available for flight optimisation and
possible downlink
The aircrew may be asked by ATC to ‘Report ready for descent’

9. Integrated Air Traffic Management Demonstration
ATC starts Controlled Time of Arrival [CTA] process
Using a datalink, the AMAN manager requests an RTA Window from
SAS646 for the CTA point.
The CTA point selected for this demonstration is SA614
• Close to TEB, approximately 35nm from touchdown and has an
altitude constraint of FL100
Time Window
Request

10. Integrated Air Traffic Management Demonstration
SAS646 responds with RTA ‘Time Window’
The aircrew responds to ATC with an RTA ‘Time Window’
This time information contains
• Estimate Time Arrival [ETA] – unconstrained time at CTA point
• Earliest possible time and
• Latest possible time
This time information is displayed in the AMAN landing list
RTA Time Window
ETA, Earliest, Latest times

11. Integrated Air Traffic Management Demonstration
ATC issues a CTA to the flight
The AMAN manager positions the flight, as close to the ETA within the
‘time window’, considering
• The aircraft’s time preference / time capabilities, and
• Any other flights
[If the time window was not suitable SAS646 would remain under AMAN-P
control / advisories for delay management and a CTA would not be sent]
CTA

12. Integrated Air Traffic Management Demonstration
SAS646 responds again
The aircrew reviews the time received and agrees to fly to the CTA
SAS646 communicates this acceptance to ATC via datalink
This results in a HMI change at the AMAN position
• Time window display collapsed to show the agreed time, with a
smaller time window around it [ +/- 30 seconds]
CTA
CTA agreed

13. Integrated Air Traffic Management Demonstration
SAS646 uses Required Time of Arrival [RTA]
The aircrew enters the CTA as a required Time of Arrival [RTA]
in their onboard functionality
This triggers a new trajectory which can be
• Sent to the ground upon a request or
• Automatically sent to the ground
New trajectory

14. Integrated Air Traffic Management Demonstration
ATCO HMI changes
To denote the new ‘state’ of the RTA flight, ATCO HMI changes
include
• The flight is flagged differently on the AMAN-P HMI
• The flight is flagged differently on the ATCO HMI
In addition, a vertical window is provided for the ATCO, showing the
vertical details of the downlinked trajectory

15. Integrated Air Traffic Management Demonstration
SAS646 flies to its CTA
SAS646 continues to fly to its agreed time for SA614 and
ATC attempts to stay ‘hands-off’ for the flight
If it hasn’t received a descent clearance beforehand, the crew will
also report when it is approaching its Top of Descent [ToD] point.

16. Integrated Air Traffic Management Demonstration
SAS646 flies to its CTA
If, at any stage, either . .
• the crew of SAS646 does not wish to [or cannot] continue on RTA
or
• ATC cannot allow the flight to continue self-managing to its time
. . . .then the CTA can be cancelled
In that event the flight is brought back under the AMAN-P process
