The Analysis Tool was written in Swing Java and required the development of 48+ Java classes - shown below. Some of the classes are common, some are for performance analysis only, others are for constraints analysis. This work required the following additional disciplines: aircraft flight planning, aircraft performance, statistics, regression analysis, sampling theory, parsing of data from input sources (i.e. radar tracking, flight plans, waypoints, points, aircraft performance data), constraint analysis algorithms, random access retrieval and mathematics of map projections. EUROCONTROL bought this software in Jul 2004.
For performance analysis, the Analysis Tool provides the means of measuring climb and descent performance figures in terms of the rate of climb (ROC) and rate of descent (ROD) within height bands – for selected samples of aircraft.
For constraint analysis, the Analysis Tool compares climb profiles for a large statistical sample of flights leaving 30 major airports, establishing quantitative measures of the following:
- - Flights that adhere to strategic constraints in accordance with pre-calculated profiles.
- - Flights that do not adhere to strategic constraints as calculated, but which nevertheless overfly the calculated constraint points.
- - Flights that do not overfly the calculated constraint points.
