Horizontal Flight Efficiency Dataset
Please note that additional quality control measures detected a limited number of abnormal flight trajectories starting towards the end of 2015 which were removed by applying an additional filter as of 01 January 2015. Due to this quality improvement, the period January 2015 - May 2016 might differ slightly from older data releases.
Data description
Horizontal en-route flight efficiency compares the length of actual or planned flight trajectories to the corresponding “achieved” distance.
The achieved distance apportions the Great Circle Distance between two points within the European airspace (reference area). If the origin/destination airport is located outside of European airspace, the entry/exit point into the reference area is used for the calculation.
The planned trajectory is derived from the flight plans submitted by airspace users to the Network Manager. The actual flown trajectory is based on processed radar track data (a.k.a. correlated position reports or CPR) submitted by ANSPs to the EUROCONTROL Enhanced Tactical Flow Management System (ETFMS).
KEP and KEA are performance indicators measuring horizontal en-route flight inefficiency in flight plans (KEP) and in actual flown trajectories (KEA) over a period of 12 months. Please note that the values are NOT monthly averages but the average over the entire 12 months period preceding the given END-DATE.
The KEP indicator is the horizontal flight efficiency calculated using the last filed flight plans to describe the trajectories, while KEA uses the actual trajectories generated via radar data. In order to smooth out the influence of unusual events, the ten best days and the ten worst days (for each measured area) are excluded from the computation.
Methodology
Horizontal en-route flight efficiency methodology is fully consistent with the Single European Sky (SES) Performance Scheme [see (Guastalla 2014) ].

Calculated Field(s)
The indicator is calculated as the ratio of the two sums (length of trajectories and achieved distances), over all flights considered:
\[ {HFE}_j = ( \frac{\sum_{f,p} L_{fjp}}{\sum_{f,p} H_{fjp}} - 1 ) % \]
where \(L\) is the length of the trajectory and \(H\) is the achieved distance; the index \(f\) is the flight, \(j\) is the airspace and \(p\) is the portion considered.
From the table above \(L\) is \(\text{DIST_FLOWN_KM}\), while \(H\) is \(\text{DIST_ACHIEVED_KM}\).
