EDDV – Hannover Airport

Tier A (measured) · 420 movements in 2026 · milestones measured from APDF

Good coverage. Nearly every movement in 2026 is picked up, and 71% of the position reports expected while taxiing out actually arrive. Roughly half to most of each ground movement is received — usable, but with gaps that will show in any surface event derived from it.

Departures

off_s is good when negative – the track began before take-off.

Distribution of off_s. Zero is take-off. 22 movement(s) fall outside +/-30 min and are excluded from the plot (2026: 4 below / 3 above, 2025: 4 below / 1 above, 2024: 8 below / 2 above). They are included in every percentile below.

When the track starts, relative to take-off (minutes)

period n p10 p50 p90
2026 210 -13.9 -7.5 +0.1
2025 209 -12.3 -5.1 +0.2
2024 224 -14.6 -7.4 -0.2
delta 2026-2025 -1.6 -2.4 -0.1

How much of the taxi-out was observed, across all movements. The dashed line is every aerodrome pooled; a curve to the right of it is better, because more of this aerodrome’s movements were well observed.

How much of the taxi-out was received (1.00 = every expected report arrived)

Arrivals

land_s is good when positive – the track ran on past landing.

Distribution of land_s. Zero is landing. 24 movement(s) fall outside +/-30 min and are excluded from the plot (2026: 9 below / 3 above, 2025: 1 below / 5 above, 2024: 1 below / 5 above). They are included in every percentile below.

When the track ends, relative to landing (minutes)

period n p10 p50 p90
2026 209 +4.6 +9.2 +13.8
2025 201 +5.1 +9.9 +13.5
2024 216 +5.5 +9.2 +14.4
delta 2026-2025 -0.5 -0.7 +0.3

How much of the taxi-in was observed, across all movements. The dashed line is every aerodrome pooled; a curve to the right of it is better, because more of this aerodrome’s movements were well observed.

How much of the taxi-in was received (1.00 = every expected report arrived)

Where the coverage is

Each position report is placed on a hexagonal grid over the aerodrome, on a log colour scale: one apron cell can hold thousands of reports while a runway threshold holds tens. Empty ground is surface the receivers do not reach.

Against the fleet

How this aerodrome compares with the 89 aerodromes with measured milestones. Typical aerodrome is the median across all of them. Rank is this aerodrome’s position among them, 0 (lowest) to 100 (highest).

measure this aerodrome typical aerodrome rank (0–100)
Coverage index 0.853 0.590 62
Departures seen (%) 100.0% 99.7% 75
Taxi-out received (median) 0.713 0.191 61
Taxi-in received (median) 0.998 1.000 39
Track start vs take-off (min, median) -7.5 -1.8 35
Track end vs landing (min, median) +9.2 +7.2 69

Higher rank is better everywhere except track start vs take-off, where a low value is the good case.

Was each flight tracked as one flight?

A poor coverage number can mean the receivers heard nothing, or that the algorithm cut the flight’s track up. This separates them.

period One flight, one track (%) Split across tracks (%) Merged with another flight (%)
2026 departures 90.0% 9.0% 1.0%
2026 arrivals 86.7% 11.0% 1.9%
2025 departures 93.3% 4.8% 1.4%
2025 arrivals 96.0% 2.0% 1.5%
2024 departures 93.3% 4.4% 1.8%
2024 arrivals 95.9% 1.8% 1.8%

The underlying counts

Everything above is derived from these. Typical taxi times are context: the same 200 seconds of reception is most of a short taxi and a fraction of a long one.
