TPM Review – ATS (Editorials)

Presented by TOC

 

Summary

The ATS section of the Technical Professional Manual is robust in policies and some of them need updating. These updates range from small grammar fixes to major overhaul or deletion.

Introduction

1.1. The ATS section of the Technical Professional Manual (TPM) contains policies back 30 years, some of which are in need of minor edits to current documents whereas others need major overhaul.

1.2. Edits must also be made to ensure continuity and harmonization of word usage. This paper details only the editorials that are needed within the ATS section of the TPM.

Discussion

2.1. The TPM contains many policies, some of which date back to its inception. Due to changes in technology and application among other matters there is a need for a book wide update.

2.1.1. This paper outlines edits that amount to minor word changes to work toward harmonization with ICAO documents.

2.1.2. Some of the existing policies also feature definitions that are not within in the Acronyms and Terms section of the TPM and should be placed there. There should be a hyperlink featured within the policy leading to the definition itself.

2.1.3. There are a few policies which are currently within the TPM that do not propose any specific action or requirement but rather just state the definition. These policies are proposed for movement as well as the information is still useful and valid but may not be a policy unto its own.

2.2. ATS 3.3 – Harmonization of the Airspace Classification.

2.2.1. Within the opening of the policy the phrase, “MA’s shall urge ATS Authorities,” ATS Authorities is referring to the ANSP or ANSPs, which is the appropriate term to use. The proposed revision is “MAs shall urge ANSP(s).”:

IFATCA TPM (2019), ATS 3.3 – Harmonization of the Airspace Classification
Proposal:

MAs shall urge ATS Authorities ANSPs to co-ordinate and harmonise with all neighbouring states their national airspace classification, in accordance with ICAO Annex 11 Appendix 4, to permit safe and efficient operating conditions to all airspace users and air traffic controllers. Airspace classification should be appropriate for the traffic operating in the airspace, to avoid over and under classification. As traffic situations change, the classification may have to change accordingly. Local operational controllers should be involved in the airspace classification process.

 

2.3. ATS 3.4 – Standardisation of Regional Transition Altitudes.

2.3.1. This policy needs a minor edit to include “shall” prior to the words “be implemented” to correct the phrase to viable English:

IFATCA TPM (2019), ATS 3.4 – Standardisation of Regional Transition Altitudes
Proposal:

Standardisation of Transition Altitudes on a region wide basis shall be implemented where applicable.

 

2.4. ATS 3.7 – Sector Capacity Values.

2.4.1. This policy goes so far as to state “defines” in reference to the 2 definitions. Therefore, it is suggested to place these definitions within the Acronyms and Terms section of the TPM:

IFATCA TPM (2019), ATS 3.7 – Sector Capacity Values
Proposal:

IFATCA defines:

Sector Capacity: The maximum number of flights that may enter a sector per hour averaged over a sustained period of time, to ensure a safe, orderly and efficient traffic flow.

Occupancy Counts: The number of flights occupying a sector simultaneously during a specified period of time.

[EDITORIAL: MOVE TO ACRONYMS AND TERMS]

 

2.5. ATS 3.8 – ATC within ICAO Assigned International Airspace.

2.5.1. This paragraph needs a few minor grammatic editorials. The first line is missing the word “shall” prior to “not”, it should be adapted to “shall not”. Additionally, the capitalization of the word NOT should be remedied to a lower case for consistency. For further clarity the simple / marks should be altered to say and/or.

IFATCA TPM (2019), ATS 3.8 – ATC within ICAO Assigned International Airspace
Proposal:

The current ICAO assignment of international airspace within ICAO ‘NOT’ shall not be modified and/or changed based solely on the development and/or implementation of technology by one or more States, unless agreed to by all MAs concerned.

 

2.6. ATS 3.9 – Radar Monitoring.

2.6.1. The first sentence of this policy needs an edit for harmonization with the rest of the manual. The abbreviation of PBN should be housed between parenthesis, such as (PBN). The revised sentence would read, “Any introduction of Performance Based Navigation (PBN) routes that are closely spaced should be subjected to safety analysis.”

2.6.2. This policy needs updating and edits beyond the scope of this paper and it is therefore suggested that it be added to the upcoming TOC working program.

IFATCA TPM (2019), ATS 3.9 – Radar Monitoring
Proposal:

Any introduction of Performance Based Navigation (PBN) routes that are closely spaced should be subjected to safety analysis. Such a safety analysis may result in hazards being identified that require automated monitoring assistance for the controller to adequately mitigate the hazard.

 

2.7. ATS 3.13 – Mixed Mode Operations.

2.7.1. The first sentence reads more as a definition than policy and should be moved to the Acronyms and Terms section of the TPM. This is also beneficial since such a definition is not already included.

2.7.2. There is a small edit that needs to be made in the final sentence of the policy, which should be reworded to read “shall take place to ensure that the change in the ATM system does not increase controller workload to an unacceptable level.” The replacement of the word “must” with “shall” is to continue harmonization with ICAO literature.

IFATCA TPM (2019), ATS 3.13 – Mixed Mode Operations
Proposal:

Mixed mode operations are defined as ATM Operations that require different procedures due to variances in airspace users’ characteristics and/or ATM design within the same area of controller responsibility.

[EDITORIAL: MOVE TO ACRONYMS AND TERMS] […]

When safety of a Mixed Mode Operation cannot be completely managed at an intrinsic level, assessment must shall take place to ensure that the change in the ATM system does not increase controller workload to an unacceptable level.

 

2.8. ATS 3.14 – Virtual Centers and Functional Airspace Blocks.

2.8.1. This section needs several editorial changes. The title of the policy, “Virtual Centers and Functional Airspace Blocks,” uses the Americanized spelling of centre, which should be corrected for uniformity.

2.8.2. In the first sentence, the word “must” is replaced by the word “shall” to maintain continuity within the TPM and conformity with ICAO.

2.8.3. In second sentence, the word “and” is missing between operational and legal.

IFATCA TPM (2019), ATS 3.14 – Virtual Centers and Functional Airspace Blocks
Proposal:

ATM data must shall be of sufficient quality, reliability and integrity for its intended use.

Organisations that provide ATM services beyond state borders shall clearly define the operational and legal implications of providing these services, and train controllers in the implications.

The efficient creation and management of an FAB does not necessarily require the physical concentration of all ANS functions within a single centre.

[…]

 

2.9. ATS 3.17 – The Use of Safety Nets in ATM.

2.9.1. The first part of the policy reads as more of a definition than policy and would fit better within the Acronyms and Terms section of the TPM.

IFATCA TPM (2019), ATS 3.17 – The Use of Safety Nets in ATM
Proposal:

A safety net is an airborne and / or ground based function, the sole purpose of which is to alert the pilot or controller of the imminence of collision of aircraft, aircraft and terrain / obstacles, as well as penetration of dangerous airspace.

[EDITORIAL: MOVE TO ACRONYM AND TERMS]

 

2.10. ATS 3.18 – Controller Tools.

2.10.1. The current policy amounts to more of a definition than a standalone policy and therefore should be moved to the Acronym and Terms section of the TPM.

IFATCA TPM (2019), ATS 3.18 – Controller Tools
Proposal:

Controller Tools (CTs) are functions of an ATM system that enhance a controller’s ability to meet the objectives of ATS. They provide information that assists controllers in the planning and execution of their duties, rather than dictating a course of action.

[EDITORIAL: MOVE TO ACRONYM AND TERMS]

 

2.11. ATS 3.19 – Conflict Detection Tools.

2.11.1. The first 2 sentences read as more of a definition than policy and should be moved to the Acronym and Terms section of the TPM.

2.11.2. In the final section of the policy, the word “must” needs to be replaced by “shall” to continue conformity with ICAO documents.

IFATCA TPM (2019), ATS 3.19 – Conflict Detection Tools
Proposal:

Conflict Detection Tools (CDTs) are computer based Controller Tools that identify conflicts and then provide system generated conflict advice to controllers.

CDTs can provide conformance monitoring to ensure that aircraft comply with instructions issued to resolve a detected conflict.

[EDITORIAL: MOVE TO ACRONYM AND TERMS]

Responsibility and legal implications should be fully addressed before implementation of CDTs.

During degraded modes, clearly defined operational procedures must shall exist. Nuisance and false alerts must shall be kept to an absolute minimum.

 

2.12. ATS 3.21 – Area Proximity Warnings.

2.12.1. This current policy is a definition rather than a policy and should be relocated to the Acronyms and Terms section of the TPM.

IFATCA TPM (2019), ATS 3.21 – Area Proximity Warnings
Proposal:

An Area Proximity Warning (APW) is an alert provided to a controller of the imminent incursion of a flight into “special-use” airspace.

Note – The response to such a warning will be dictated by the nature of the airspace in question and its specific requirements.

[EDITORIAL: MOVE TO ACRONYM AND TERMS]

 

2.13. ATS 3.22 – Route Conformance Monitoring Systems (RCMS).

2.13.1. This existing policy goes so far as to list itself as definitions; as such this policy will be moved to the Acronyms and Terms section of the TPM.

IFATCA TPM (2019), ATS 3.22 – Route Conformance Monitoring Systems (RCMS)
Proposal:

Definitions:

A ROUTE CONFORMANCE MONITORING SYSTEM (RCMS) is a function of an Automated ATS System that monitors the position of an aircraft to detect when it deviates from its route. An RCMS is considered to be a Controller Tool.

A ROUTE DEVIATION ALERT (RDA) is an alert provided to a controller to notify that an aircraft’s position is displaced outside the tolerances defined within RCMS.

Note: Certain processing may be suspended.

An ESTIMATED TIME OVER DEVIATION ALERT (ETODA) is an alert provided to a controller to notify a controller that a new estimate is outside specified parameters when compared to a previous estimate.

[EDITORIAL: MOVE TO ACRONYM AND TERMS]

 

2.14. ATS 3.30 –Air Traffic Flow Management – Implementation.

2.14.1. One minor edit is required to keep consistency in grammar throughout the policy of changing “Procedures should be in place” to “Procedures are in place.”

IFATCA TPM (2019), ATS 3.30 – Air Traffic Flow Management – Implementation
Proposal:

[…]
  • Procedures should be are in place to allow controllers to report occasions where they felt overloaded or sector capacity values were exceeded. Feedback should be given to the reporting controller.

 

2.15. ATS 3.33 – Merging and Sequencing Concepts.

2.15.1. The bulk of the policy remains strong and valid with the need of a small alteration. The need for the system capability may not be present in all cases but can be crucial in some scenarios. Therefore, the final bullet point needs to be amended to read:

IFATCA TPM (2019), ATS 3.33 – Merging and Sequencing Concepts
Proposal:

[…]
  • Integration They are integrated with others with other systems and adjacent units is possible if required.

 

2.16. ATS 3.38 – Terrain and Obstacle Clearance Responsibilities.

2.16.1. “Must” will be changed to “shall” throughout the policy for continued harmonization with ICAO documents.

2.16.2. Within the first paragraph it is proposed to further change “air crew” to “crew”.

IFATCA TPM (2019), ATS 3.38 – Terrain and Obstacle Clearance Responsibilities
Proposal:

Responsibility for terrain and obstruction clearance must shall be clearly defined and always must shall always lie either with the air crew or ATC. There must shall never be a situation where doubt exists about who is responsible for this task.

 

2.17. ATS 3.43 – Crisis Management.

2.17.1. The current policy utilizes the phrase OCIR without it being defined either within the phrase or within the Acronyms and Terms section of the TPM.

2.17.2. It is proposed to add an IFATCA specific definition including a graphical definition of OCIR to the Acronyms and Terms section of the TPM. The proposed definition would read:

IFATCA TPM (2019), ATS 3.43 – Crisis Management
Proposal:

 [EDITORIAL: ADD THE FOLLOWING TO ACRONYMS AND TERMS]

OCIR Model: a practical method for ATC crisis management. It describes four steps in incident stabilization and control. As the primary reaction to any disruption is directed inwards in the organization to regain control, the OCIR model suggests a broader focus by communicating, consulting and cooperating with external parties in all phases of crisis response.

 

2.18. ATS 3.44 – Moving to a New Facility.

2.18.1. The first point of the list should say defining in lieu of define since it is the controllers that will be doing the work, and for consistency with the other bullet points.

2.18.2. For continuity within the list, item b) should have a period at the end.

IFATCA TPM (2019), ATS 3.44 – Moving to a New Facility
Proposal:

[…]

a) Define Defining facility requirements and user needs.

b) Participating in the risk and safety assessment processes.

[…]

 

Conclusions

3.1. There are many policies in need of review which ranges from minor edits to being placed in a totally different section of the TPM.

Recommendations

4.1. It is recommended that the abovementioned sections of the Technical and Professional Manual (TPM) be amended accordingly, as described in Section 2 of this working paper.
