Apron Areas • Apron areas provide space to service aircraft • Also serve to park them overnight and during flight layovers Commuter traffic at DFW (2 Saab 340s)

Aircraft Parking Configurations Three types of parking configurations have been used at most airports: • Taxi-in and Push-out • Taxi-in and Taxi-out (front) • Taxi-in and Taxi-out (back) The configuration depends largely on the terminal design system employed

Determining Gate Capacity at the Airport • Gates can be a critical asset at many airports • The number of gates is usually determined using simple demand and supply analysis formulas • Gates can be “owned” by airlines (leased from the airport authority)

Gate Analysis (Ashford’s Method) • Aircraft Parking and Gate Analysis • Can be executed using ramp (sort of Gantt) charts where flights are plotted against time over a 24 hr. period. • Gantt charts show activities over time
Advanced Airport and Airspace Capacity Seminar 19 of 38
Gate Analysis (Ashford’s Method) A simple formula to estimate the number of gates proposed by Norman Ashford is: U = Utilization factor (0-1) F = No. of flights G = No. of gates available S = Slots per day Usually S = 20-30 per day (24 hour period) U F GS() ------------=

Loading Gates • Come in many flavors and sizes • Large articulated units able to serve Wide-body aircraft • Small units serving regional jets

Waiting Lounges

Waiting Lounges • Dimensionally departure lounges has been sized using static measures of effectiveness (IATA standard) • ITA Standard for Departure Lounges 8.5 ft2/acft. seat. • IATA Waiting and circulation areas >10.8 ft2/person more than 15 min. • Architectural standard with baggage 15 ft2/person • Many airlines use 15 ft2/Pax @ 87%* load factor * 87% of passengers are at the waiting lounge 15 min. before departure.
