Download Report

PRB monitoring

▪ Portugal achieved a KEA performance of 1.65% compared to its target of 1.80% and contributed positively towards achieving the Union-wide target. KEA improved by 0.14 p.p. compared to 2020.

▪ SCR remained at similar levels to 2020, while KEP improved by 3%.

▪ The share of CDO flights decreased by two p.p..

▪ Both additional time in terminal airspace and additional taxi out time have improved by 23% and by 16% respectively.

En route performance

Horizontal flight efficiency of the actual trajectory (KEA) (KPI#1), of the last filed flight plan (KEP) (PI#1) & shortest constrained route (SCR) (PI#2)

Terminal performance

Additional taxi-out time (AXOT) (PI#3) & Arrival Sequencing and Metering Area (ASMA) time (PI#4)

Focus on ASMA & AXOT

AXOT

Additional taxi-out times at Lisbon (LPPT; 2019: 3.96 min/dep.; 2020: 2.68 min/dep.; 2021: 1.93 min/dep.) decreased for the second year in a row. These decrease is driven by the performance during the first 4 months, considerably better than in 2020. However, in the second part of the year the additional taxi-ou times increased in line with the traffic recovery, averaging 2.21 min/arr. between June and December. A similar monthly evolution with respect to 2020 was observed at Porto, where the additional taxi-out times in October and December averaged 2.54 min/dep..

ASMA

Like the additional taxi-out times, the additional times in the terminal airspace at Lisbon (LPPT; 2019: 2.75 min/arr.; 2020: 1.51 min/arr.; 2021: 1.15 min/arr.) further decreased in 2021 due to the much better performance in the first 3 months of the year 2021 compared with 2020. At Porto (LPPR; 2019: 1.34 min/arr.; 2020: 0.61 min/arr.; 2021: 0.57 min/arr.) the additional ASMA times were around 0.50 min/arr. for most of the year, reaching or exceeding 1 min/arr. only during May and December.

Share of arrivals applying continuous descent operations (CDOs) (PI#5)

Focus CDOs

All airports have shares of CDO flights (well) above the overall RP3 value in 2021 (30.5%), ranging from 33.5% (Cascais - LPCS) to 100.0% (Flores - LPFL). It should however be noted that Flores and Horta had a limited number of flights in 2021: respectively 1 and 158 arrivals. All airports that were monitored in 2020 have a reduction of the share of CDO flights, except for Madeira, which had an increase of 1.3 percentage points. The monthly values at Cascais decreased significantly from 50.9% in March to 26.1% in December.

According to the Portuguese monitoring report: CDO is the basis for the arrival route structuring within Lisbon FIR. Nonetheless, most of the times a shorter route is provided to the arriving traffic. Since these shorter routes are not covered by the STARs, the resulting final CDO percentage is negatively affected, even though the traffic is flying more efficient and shorter routes.

Civil-Military dimension

Focus on Civil-Military dimension

Update on Military dimension of the plan

Information from 2020 report repeated. No new information provided as an update.

Military - related measures implemented or planned to improve capacity

Environment: The military are updating the CNS equipment to be able to fly on more efficient routes, especially when operating as General Air Traffic. In this sense, several fleets are being modified to comply with the latest CNS requirements and new aircraft are scheduled for delivery soon. Regarding airspace design, Portugal is currently undergoing a major restructuring of its airspace structures in order to improve its overall capacity and adequacy to both military and civil requirements.

Capacity: As already mentioned in the environment KPA, a major airspace restructuring is currently ongoing in Portugal, involving all the main stakeholders, in order to accommodate for both the military and civil requirements.
