Airport Trend

	Function		Airport Trends
	Description		The airport trends KPI gives a view of the traffic DEMAND, and the trends in terms of traffic and traffic delay.
	Access		Workspace > KPIs > Airport Trend KPI
	Input		Aerodrome(s)		One or more Aerodrome ICAO Identifiers separated by a space or comma
			WEF		Start of the trending period (hh:mm or hhmm)
			UNT		End of the trending period (hh:mm or hhmm)
			Interval		The time step between each count bar - in the example every 5 minutes
			Duration		The time period for each interval during which we accumulate the counts for the specified duration
	Output		The tool will perform a B2B query, obtaining the flights arriving/departing for the specified time period [WEF;UNT], and then compute a the Departure Trend. For each counting period one can see which flights have departed on time, or if not yet departed, if they are pushed back, taxying, or sequenced for departure. If flights have not departed on time, the source of the delay can be analysed. Hover over the bar to get the exact type of information and the corresponding value.
					The left hand graph gives a view of the traffic DEMAND, categorized by • Flight State – Suspended, Filed, Departed (Airborne or Terminated) • CDM state – Targeted (T-DPI_t), Sequenced (T-DPI_s), or Pushed back (A-DPI) • Regulated or not The right hand graph gives a view on the generated delays – • Classical ATFCM delay – delay due to the (pre-)allocation of CTOTs • “Airport” delay – delay (negative or positive) due to differences between ATC issued TTOTs and the original demand ETOT/regulated-demand CTOT. This value is only computed for A-CDM airports. • “Take-off delay” – differences between the planned ATC take-off time and the actual take-off time.
