When is a flight of an aeroplane within the scope of CAT.GEN.MPA.205(a) not required to be tracked?

The flight does not need to be tracked when Conditions 1, 2 and 3 are met altogether: (1) the planned route and planned diversion routes are in airspace blocks where ATS surveillance service is normally provided; (2) that ATS surveillance service is supported by ATC surveillance systems locating the aircraft at time intervals with adequate duration; and (3) the operator has provided all competent ANSPs for those airspace blocks with the necessary contact information.

If an aeroplane's planned route is in airspace where ATS surveillance is normally provided, but the operator has not given the competent ANSPs the necessary contact information, does the flight need to be tracked?

Yes, the flight shall be tracked because Condition 3 is not met. The table states that if either Condition 1, Condition 2 or Condition 3 is not met, the flight shall be tracked.

What does the guidance say about a temporary or unexpected issue that results in a lack of aircraft tracking data?

Lack of aircraft tracking data due to a temporary or unexpected issue may be acceptable, as referenced in AMC1 CAT.GEN.MPA.205. Examples include airborne equipment found inoperative, transmission link disturbed by environmental factors, or an issue with ground-based or space-based infrastructure.

For an aeroplane within the scope of CAT.GEN.MPA.205(a), what does the table say about a flight where the planned route is in airspace blocks without normal ATS surveillance service?

The flight shall be tracked, because Condition 1 is not met. The table indicates that if any of the three conditions is not met, the flight shall be tracked.

Q: What are the three conditions that, if all met, exempt an aeroplane flight from the aircraft tracking requirement?

Condition 1: planned route and planned diversion routes are in airspace blocks where ATS surveillance service is normally provided. Condition 2: the ATS surveillance service is supported by ATC surveillance systems locating the aircraft at time intervals with adequate duration. Condition 3: the operator has provided all air navigation service providers competent for those airspace blocks with the necessary contact information.

Q: What is the consequence if only one of the three conditions is not met for a flight?

The flight shall be tracked, as stated in the table: 'Either Condition 1, Condition 2 or Condition 3 is not met' leads to the case 'The flight shall be tracked'.

Q: What are the indicative examples of temporary or unexpected issues that may make lack of tracking data acceptable?

Examples (indicative and not exhaustive) are: airborne equipment found inoperative, transmission link disturbed by environmental factors, and an issue with the ground-based infrastructure or the space-based infrastructure.

Q: What does the guidance state about the ATC surveillance systems in Condition 2?

Condition 2 requires that the ATS surveillance service provided in all airspace blocks determined by Condition 1 is supported by ATC surveillance systems locating the aircraft at time intervals with adequate duration.

ED Decision 2017/023/R

DETERMINING WHETHER A FLIGHT NEEDS TO BE TRACKED

Table 1 provides a summary of the cases applicable to an aeroplane which is within the scope of CAT.GEN.MPA.205(a).

Table 1: Cases applicable to the flight of an aeroplane subject to the aircraft tracking requirement

Condition 1:

The planned route and the planned diversion routes are included in airspace blocks where ATS surveillance service is normally provided.

Condition 2:

The ATS surveillance service provided in all airspace blocks determined by Condition 1 is supported by ATC surveillance systems locating the aircraft at time intervals with adequate duration.

Condition 3:

The operator has provided all air navigation service providers competent for the airspace blocks determined by Condition 1 with the necessary contact information.

Case considered:

Aeroplane that is within the scope of CAT.GEN.MPA.205(a).

Conditions 1, 2 and 3 are met altogether.

The flight does not need to be tracked (refer to CAT.GEN.MPA.205(b)).

Note:

The operator should check at regular time intervals that Conditions 1, 2 and 3 are still met (refer to AMC2 CAT.GEN.MPA.205).

Either Condition 1, Condition 2 or Condition 3 is not met.

The flight shall be tracked (refer to CAT.GEN.MPA.205(b)).

Note:

Lack of aircraft tracking data due to a temporary or unexpected issue may be acceptable (refer to AMC1 CAT.GEN.MPA.205). Examples of issues (list is indicative and not exhaustive): airborne equipment found inoperative, transmission link disturbed by environmental factors; issue with the ground-based infrastructure or the space-based infrastructure.
