Airport A-CDM KPIs

	Function		Airport KPIs
	Description		The airport KPIs tool permits a user to obtain KPIs for both A-CDM and non A-CDM airports
	Access		Workspace > KPIs > Airport Dashboard KPI
	Input		Aerodrome(s)		One or more Aerodrome ICAO Identifiers separated by a space or comma
			Mode		Variability or Delay
					Many of the KPI tools offer a mode parameter - which can take a value of either VARIABILITY or DELAY. The difference between these 2 values is best explained through an example. Consider, 2 flights – one arriving 5 minutes early and one arriving 5 minutes late. When computing an “arrival KPI” we could either say – • On average, the delay was zero ( (-5 + 5) / 2) • On average, the variability was 5 minutes (i.e. ( |-5| + |5|) / 2) In other words, variability determines the average error in terms of magnitude, ignoring if values are actually –five and +five. Delay on the other hand, does care about the sign of values (-five or +five).
			Auto Refresh Mode		never, every 30s, min, 2 min, 3 min, 4 min, 5 min
			Past (In min)		With reference to [Go] how may minutes to look in the past
			Future (In min)		With reference to [Go] how may minutes to look forward
	Output		The tool will perform a B2B query, obtaining the flights arriving/departing for a time period of [-2h, +1h], and then compute a number of KPIs. Most of the KPIs are related to flight departures, with only 2 related to arrivals.
					If the airport is an A-CDM airport then a full set of departure KPIs are shown – • ATFM DLY (Past) For departed regulated flights, determine the average delay value (CTOT-ETOT) • ATFM DLY (Future) For future departing regulated flights, determine the average delay value (CTOT-ETOT) • APT DLY(Past) For departed non-regulated flights, determine the average (T-DPI_s TTOT – ETOT) • APT DLY(Future) For future departing non-regulated flights, determine the average (T-DPI_s TTOT – ETOT) • ATOT – ETOT For departed non-regulated flights, determine the average take off ‘imprecision’ • ATOT – CTOT For departed regulated flights, determine the average take off ‘imprecision’ • ATOT – T_DPIs For departed flights determine the average ‘imprecision’ of the ATC pre-sequenced TTOT • ATOT – A-DPI For departed flights determine the average ‘imprecision’ of the last TTOT (given after push-back) In non-CDM airports, only the following subset of departure KPIs are given – • ATFM DLY (Past), ATFM DLY (Future), ATOT – ETOT, ATOT – CTOT In all airports (A-CDM or not) the following arrival KPIs are shown – • ATA – ETA For arrived non-regulated flights, determine the average arrival ‘imprecision’ • ATA - CTA For arrived regulated flights, determine the average arrival ‘imprecision’ T_DPI_s : The message containing the flight TSAT and TTOT, following ATC pre-sequencing
