  2. Context description (1) • Before operating change of STARs or runways, or operating go-around and holds, it is important to keep in mind that the scope of a STAR modelised in IPAS is not the same than the operational one. • The IPAS STAR integrates the approach into the STAR path, and thus, establishes a direct and unique link from the STAR to the runway: • A runway may be used by several STARs, • but a STAR is connected to a unique runway. • A direct consequence, for example, is that it is not possible to change a runway for a flight without changing the STAR.

  3. Context description (2) Operational STAR Last approach section (in green)is not part of the STAR. IPAS STAR (in modelisation) Last approach section (in green)is here part of the STAR.

  4. Context description (3) Change of runway by controller • Until ACE2008B, under execution conditions, it was always possible to change a runway for a flight. The Rte Dataset is always updated with the new runway • However, according to the setting of the parameters “AUTOMATIC_STAR_ALLOCATION” and “ALLOW_SID_STAR_INSERTION”, the FM could change the runway without re-allocating a corresponding STAR. This was not normal: as soon as a change of runway is possible, if the current IPAS STAR does not correspond to the new runway, the FM should reallocate a proper STAR. • If the change of runway is possible, from the point of view of the FM configuration setting, then the automatic STAR reallocation for a provided runway should not be subject to any configuration parameters. • Nevertheless, if no STAR can be associated to the provided runway, it is always mandatory to update the runway (in the Dataset) and so, to leave the flight in a state inconsistent from the point of view of the association STAR/Runway (on the same way we can get it • through the actual configuration parameters).

  5. Context description (4)“New STAR” were rejected… STAR 1 Divergence waypoint Entry waypoint Common Path of the STARs STAR 2 Before ACE2009A the Flight Manager (FM) rejected the “New STAR” orderwhen : • The aircraft was no more on the common path   Figure case Acft : New STAR in FM • BeforeACE2009A the FM didn’t accept to change a STAR when there was no common waypoint between the STAR. • SinceACE2009A In the case the aircraft is no more on the common path an Entry waypoint shall be provided.

  6. Context description (5)“New STAR” were rejected… STAR 1  STAR Entry Point STAR 2 Before ACE2009A the Flight Manager (FM) rejected the “New STAR” orderwhen : • The aircraft was no more on the common pathor • Entry point of the New STAR did not match the entry point of the previous STAR. (without any common point) • The aircraft was no more on the common pathor STAR without common path In case Acft : Two distinct STARs without any common point.

  7. Context description (6)IfNo previous STAR is defined , change will be issued during route STAR 1 Entry waypoint The FM computes a new P4D including a Direct to the Entry waypoint « New» STAR 2 • Since ACE2009A it will be possible to issue a “New STAR” anywhere along the STAR • and at any timeto change the STAR even though the entry point does not match the last point of the route. • A resume (entry) waypoint to the new STAR will be provided In order to cover these two issues. case Acft : New STAR computation in FM

  8. Context description (7) Runway Activation • It is possible to define in IPAS whether a runway is active or not, and whether a runway is used for takeoffs, landings or both (note that this is an implicit setting from the usage of the runway in the SID and STAR definition - takeoff in SID, landing in STAR). • Active state and the usage information are not used at all by the AIR system. The a/c can potentially take off or land on any runway declared in the system. • They are only used by the GROUND system when it is configured to allocate automatically the SID and the STAR. In that case, SID and STAR selection is based on runway state and usage. Note that this configuration has only been used in live trials. • For most of the simulations, SID and STAR are manually allocated in IPAS and runways state and usage are not considered by the GROUND system.

  9. Context description (8) Runway Activation • A part of the system is also assumed to be able to manage a dynamic change of state and/or change of usage for a runway. • However, considering that manually it is possible, whatever the runway state and usage, to: • Navigate the a/c toward any runway • Change the STAR/runway of any flight from the CWP • Then it is not necessary to manage properly neither the initial state and usage of a runway, nor to maintain them up to date. • Moreover, changing dynamically that information would mean either to: • Update manually flight and a/c data as it is done when the state and usage are not maintained, or • Leave the system reallocate automatically STAR and runway, which is probably an undesired scenario (possibility to reallocate wrong STAR, route connection to STAR to be solved manually, …)

  10. Context description (9) Runway Activation • AMAN manages its own runway activation/deactivation and departure/arrival system through the AMAN strategy. Each pre-defined strategy corresponds to the use of a certain runway configuration, and any change of runway status is expected to be input in AMAN (through the AMAN HMI) with a change of strategy. Moreover, it is also possible to close temporarily a runway through a closure slot. • In conclusion, until ACE2008B, running scenarios with runway activation/deactivation was possible without managing a formal state of the runway in the system, except the one already defined specifically for AMAN.

  11. STAR description in IPAS The Figure 1 describes the associations (real and deduced) in IPAS between the STAR, the AIRPORT and the RUNWAY. Figure 1 IPAS modelisation of STAR / RUNWAY / AIRPORT

  12. STAR description in IPAS Since ACE2009A In order to use fully the new feature developed in UR439 about the "TMA Management” (STAR // Runway change by PWP) the name of the STARs filled by the IPAS preparatory shall respect some conventions (while respecting the limit of 6 characters) in order to ease the • PWP determination of Corresponding STAR for parallel runway

  13. STAR description in IPAS • PWP determination of Corresponding STAR for parallel runway The specifications related to the change of runway are relying on the usage of the “New STAR” order: • To lower the pseudo-pilot workload, the PWP HMI shall determine if the corresponding STAR for a parallel runway exists, according to IPAS defined data. • This determination will be made by comparing the name of the current aircraft’s STAR with the name of the IPAS defined STARs associated to the current aircraft’s selected runway: • PWP-HMI tries to find a STAR whose name starts with the current STAR name and ends with a character denoting parallel runway direction (R, L….)

  14. Functional Specification STAR description in IPAS • PWP determination of Corresponding STAR for parallel runway The following table provides some illustration of that determination process:

  15. Functional Specification STAR description in IPAS • PWP determination of Corresponding STAR for parallel runway The following table provides some illustration of that determination process: This new functionality requests some conditions: • Each STAR name arriving on // runways shall STARTS with the current STAR name and ends with a character (L,R or C as defined in the IPAS Runways in the AIRPORTS panel) • When parallel runways have several entry points, each parallel arrival runway shall have a STAR defined in IPAS and these for each entry point. E.g.: If there are two entry pointsAPRIL and CMP and two // arrival runways16L and 16R at LIRF airport, As the name of STARs usually starts with the entry point (GATE) name it could be defined a STAR per runway and per entry point. • For the entry point APRIL it could be STAR names: “APR16R” and “APR16L” • For the entry point CMP it could be STAR names: “CMP16R” and “CMP16L” So an aircraft arriving by APRIL will be able to use a pre-defined STAR on both // runways 16Land 16Rand those arriving by CMP will be able to do so. The Pseudo-Pilot will be automatically proposed a parallel runway when selecting the NEW RUNWAY order and its workload will be lowered in these cases.

  16. Functional Specification STAR description in IPAS • PWP determination of Corresponding STAR for parallel runway The following table provides some illustration of that determination process: However when it is not defined this way for instance: • For an entry point APRIL it could be a single STAR name: “APR16R” • For an entry point CMP it could be a single STAR name: “CMP16L” So an aircraft arriving by APRIL planned to land on the 16R (APR16R ) will still be able to change of runway 16L using existing STAR “CMP16L” but the menu sequence on the PWP HMI will request more actions as automatic parallel runway detection will not be possible the STAR names not starting identically. APR16 and CMP16.

  17. STAR description in IPAS End of the IPAS data preparation description • The following pages are there to give you a better understanding of what will change with the PWP (Pilot working position) after the implementation of this new feature developed in UR439 about the "TMA Management” (STAR // Runway change by PWP)

  18. STAR description in IPAS  STAR 1  Divergence waypoint STAR Entry Point STAR 2 Example: OMA08R, OMA08L, OMH26R, OMH26L The IPAS STAR usually defined may be summarised by the Figure 2 and Figure 3 Figure 2: STAR with common Path • In case: There is a common path and the aircraft is still on the common path • In case: There is a common path and the aircraft is no more on the common path

  19. STAR description in IPAS STAR 1  STAR Entry Point STAR 2 Example: OMA08R, OMA08L, OMH26R, OMH26L The IPAS STAR usually defined may be summarised by the Figure 2 and Figure 3 Figure 2: STAR with common Path • In case: Two distinct STARs without any common point

  20. PWP: Change of runway by pilot(1) • The controller may issue clearances to change the runway • For the parallel runway // in case of L / R runways configuration • For any other runway in case of special event (e.g. runway unplanned closure) Case 1 is expected before reaching the approach part i.e. when the a/c is still in the common path of the STARs only expected to diverge in the L or R approach. In that case, • an input limited to the runway id should be sufficient for the system to manage the change.

  21. PWP: Change of runway by pilot (2) • The controller may issue clearances to change the runway • For the parallel runway // in case of L / R runways configuration • For any other runway in case of special event (e.g. runway unplanned closure) Case 2 may happen anywhere along the STAR. In that case, it is necessary to input the STAR associated to the runway, and then: • To input a STAR waypoint to perform a direct, or • To input a heading in order to vector the a/c to a point where a resume to the new STAR is possible, or • To store the new STAR until specific orders brings the a/c to a point where a resume to the new STAR is possible.

  22. PWP - HMI Specifications HMI Specification n°1 – Information window The Flight Information Window now displays the current STAR and Runway names, as displayed hereafter: Figure 2 – Information window The Datalink field was removed. It may be necessary to move other elements such as “ROT” and “POSITION”.

  23. PWP - HMI Specifications HMI Specification n°2 – New Route Order Menu In the context of the present UR, the New Route Order Menu was enriched with one button “NEW RUNWAY” displayed on the right of the NEW STAR button. That will allow the pilot to change the runway on which an arriving aircraft will land. Figure 3 – HMI Specification n°2 – New Route Order Menu

  24. PWP - HMI Specifications HMI Specification n°3 – Change STAR Combine Menu A new Order Menu was created, that allows the input of new orders : “Change STAR and Heading”, “Change STAR and Turn” and “Change STAR and Direct”. Therefore, this Menu contains three buttons, as follows. Figure 4 – HMI Specification n°3 – Change STAR Combine Menu

  25. PWP - HMI Specifications Specification n°4 – Runway Value Menu The Data Entry panel allows the selection of a runway amongst the list of all the IPAS-defined arrival runways of a given airport. Therefore, the Runway Value Menu will be generated by the PWP HMI, by retrieving the available runways from the IPAS-defined STAR entries. The Runway Value Menu Header shall display the name of the airport for which the runways are displayed, as follows Figure 5 – Specification n°4 – Runway Value Menu Available runways for airport LFPG The runway information, wherever presented, shall be formatted as two digits plus one optional letter.

  26. PWP - HMI Specifications HMI Specification n°5 –STAR Exclusive Value Menu A new Data Entry panel allows the selection of a STAR amongst the list of the IPAS-defined STAR for a given runway. Therefore, the STAR Exclusive Value Menu is generated by the PWP HMI, by retrieving the list of STARs heading to a given threshold (according to the IPAS STARs definitions). The name “Exclusive” refers to the fact that the listed STARs are restricted to the selected runway. Figure 6 – HMI Specification n°5 – STAR Exclusive Value Menu

  27. PWP - HMI Specifications HMI Specification n°6 –STAR Beacon Exclusive Value Menu The Data Entry panel shall allow the selection of a waypoint from an IPAS-defined STAR. It should be stressed that the STAR may not be the active STAR, but selected from the STAR Value Menu instead. Please also note that the name “Exclusive” refers to the lack of buttons “OTHER” etc.. Figure 7 – HMI Specification n°6 – STAR Beacon Exclusive Value Menu

  28. PWP - HMI Specifications HMI Specification n°7 – STAR Initial Letter Value Menu The Data Entry panel shall allow the selection of the STAR through its initial letter in the case when more than 42 STARs are definded for the destination airport. The STAR initial letter value menu shall contain the following buttons: • Letter A to Z • Numeric 0 to 9 Figure 8 – HMI Specification n°7 – STAR Initial Letter Value Menu

  29. PWP - HMI Specifications HMI Specification n°7 –Other STAR Value Menu The other STAR value shall displays al available STAR for the current destination airport beginning by the initial letter selected. It shall contain the following buttons: STAR name beginning by the same letter Figure 9 – HMI Specification n°8 – Other STAR Value Menu

  30. PWP- Functional Specifications Functional Specification n°1 – Determination of Corresponding STAR for parallel runway Next specifications related to the change of runway are relying on the usage of the “New STAR” order: • To lower the pseudo-pilot workload, the PWP HMI determines if the corresponding STAR for a parallel runway exists, according to IPAS defined data. • This determination will be made by comparing the name of the current aircraft’s STAR with the name of the IPAS defined STARs associated to the current aircraft’s selected runway: PWP-HMI tries to find a STAR whose name starts with the current STAR name and ends with a character denoting parallel runway direction.
