Above-average traffic increase affects punctuality

Despite the unexpected increase in air traffic demand, punctuality continues along a favourable path.

Even with unexpected high traffic growth and high traffic volatility, FABEC ANSPs improved their operational performance in the first six months of 2017 in comparison to the mid-year values of 2016. Nevertheless, adverse weather conditions, staffing issues and insufficient ATC capacity led to results below target values. Traffic in the first six months of 2017 increased by + 3.9 percent to 2.86 million safely controlled flights (January to June 2016: 2.75 million). Although this growth is significantly above the STATFOR baseline forecast (published in 2015), there are sizeable differences between FABEC ANSPs ranging from Belgocontrol with + 7.0 percent to skyguide with + 2.7 percent traffic increase. Furthermore, some control centres and sectors reported a local traffic boost. Today, air navigation service providers have to cope with unpredicted changes in traffic flows in terms of quantity, routings and time, which makes capacity planning in the frame of a rigid regulatory system a serious challenge.

Traffic volatility adversely affects ATC capacity
Despite the unexpected increase in air traffic demand, punctuality continues along a favourable path. In the first half of 2017, 94.8 percent of all flights in the FABEC area experienced no delays caused by air traffic control (ATFM en-route delays). 98.1 percent arrived at their destination airports on time, i.e. within 15 minutes of the scheduled time.

The average delay due to en-route ATFM measures was roughly 50 seconds per flight (0.83 min./flight), significantly less than during the same period of 2016 (74 seconds or 1.23 min./flight). The primary causes for delays were ATC capacity, adverse weather, industrial action and staffing shortages. Despite this positive trend, FABEC ANSPs will most probably not reach the capacity target for 2017.

A comparison between the delay situation in 2014 (end of RP 1) and today shows that the core area has registered an above-average deterioration in punctuality. This can partially be explained by the unexpected traffic growth after almost ten years of stagnating traffic as the industry has pushed for cost reductions. In light of the unexpected high traffic demand, this strategy may be questioned as it shows that the related underinvestment is now resulting in capacity shortfalls due to ATCO availability and system implementations.

Airport punctuality remains excellent
In the first half 2017, airport punctuality developed positively: the number of take-offs and landings at the 83 FABEC airports rose to 1.26 million (+ 2.7 percent). At the 83 monitored FABEC airports, punctuality remained excellent and slightly improved from 48.6 seconds/flight (0.81 min.) in the period from January to June 2016 to only 46.8 seconds/flight (0.78 min.) in the same period of 2017.
