3. CAPACITY

3.1. Key performance indicator

The average minutes of en route ATFM delay per flight attributable to air navigation services, calculated as follows:

(a)

the en route ATFM delay is the delay calculated by the Network Manager, expressed as the difference between the estimated take-off time and the calculated take-off time allocated by the Network Manager;

(b)

for the purposes of this indicator:

• ‘estimated take-off time’ means the forecast of time when the aircraft will become airborne calculated by the Network Manager and based on the last estimated off-block time, or target off-block time for those airports covered by airport collaborative decision-making procedures, plus the estimated taxi-out time calculated by the Network Manager;

• ‘calculated take-off time’ means the time allocated by the Network Manager on the day of operation, as a result of tactical slot allocation, at which a flight is expected to become airborne;

• ‘estimated taxi-out time’ means the estimated time between off-block and take off. This estimate includes any delay buffer time at the holding point or remote de-icing prior to take off;

(c)

this indicator covers all IFR flights and all ATFM delay causes, excluding exceptional events;

(d)

this indicator is calculated for the whole calendar year and for each year of the reference period.

3.2. Indicators for monitoring

(a)

The average time, expressed in minutes, of arrival ATFM delay per flight attributable to terminal and airport air navigation services and caused by landing restrictions at the destination airport, calculated as follows:

(i)

this indicator is the average generated arrival ATFM delay per inbound IFR flight;

(ii)

this indicator includes all IFR flights landing at the destination airport and covers all ATFM delay causes, excluding exceptional events;

(iii)

this indicator is calculated for the whole calendar year and for each year of the reference period.

(b)

The percentage of flights with en route ATFM delay greater than 15 minutes, calculated as below:

(i)

en route ATFM delay calculated in accordance with point 3.1(a);

(ii)

this indicator covers all IFR flights and all ATFM delay causes, excluding exceptional events;

(iii)

this indicator is calculated for the whole calendar year and for each year of the reference period.

(c)

The average time, expressed in minutes, of all cause-departure delay per flight, calculated as follows:

(i)

this indicator is the average delay attributable to:

• delays due to airline operations;

• en route ATFM delay reported by airspace users;

• reactionary (knock-on) delay;

• airport operations delay, including ATFM airport delay reported by airspace users caused by regulation based on traffic volume which has a reference location classified as Aerodrome Zone or Aerodrome;

(ii)

this indicator covers all IFR flights and is calculated for the whole calendar year and for each year of the reference period.
