ABSTRACT
Flight track data is used at the airports to monitor noise from aircraft during take off and landing
and to measure the noise impact on the surrounding communities. The flight track data gives the
aircraft height, speed, runway assignment, flight number and the aircraft type for arrivals and
departures. The perimeter taxiway (PT) or end around taxiway (EAT) is proposed for
construction at Dallas/Fort Worth International Airport (DFW) to permit arriving aircraft to
avoid crossing an active runway to reach the terminal gates. This concept enables the arriving
aircraft to go around the departure runway while the departure runways can operate without
interruption. Safe operations require an analysis of the arriving and departing aircraft heights.
Similar criteria are proposed for aircraft arriving over the PT to clear the aircraft taxiing on the
PT from/to the terminals. The flight track data is used to assess the safety of the current
perimeter taxiway plan. For the first time, the flight track information is used to determine the
height of aircraft where the flight paths will pass over aircraft taxiing on the perimeter taxiway.
The data analysis for each of the parallel runway operational configurations led to the
computation of the probability of flying below the prescribed minimum height established by the
Federal Aviation Administration (FAA)/Airport Operations Standards Committee (AOSC). The
proposed PT at DFW appears safe for both approach and departure operations because the
probabilities of flying below the FAA established threshold height on all eight runways are
0.000029 or less.
