The following information is given about air traffic at a particular runway of an airport. (a) Aircraft are classified into three types: heavy (H), large (L), and small (S). (b) Some relevant aircraft characteristics are as follows: Aircraft type H L Approach speed (knots) 150 Leading aircraft 130 H Mix (%) L 50 S 110 50 (c) The length of the final approach to the runway is 5 nmi. (d) The minimum separation requirements (in nmi) between successive landing aircraft on final approach are given by the matrix below Required separation distance in nmi 40 S 10 H Trailing aircraft 4 Runway occupancy time on landing (sec) 70 2.5 60 2.5 L 5 2.5 S 6* 2.5 (* These separation apply only when the landing aircraft is at the runway threshold; all other separations apply throughout the final approach) (e) A "buffer time" (BT) of 10 seconds is added to all the minimum separation times between successive landings to account for uncertainties 4 2.5 (f) The minimum separation requirements (in seconds) between successive departing aircraft are given by the matrix below Required separation distance in nmi Leading aircraft H L S Trailing aircraft L H 90 60 45 120 60 45 S 120 60 45 1. Suppose this runway is used for departures only. Find its maximum throughput capacity for departures. (No BTs are added for departures) 2. Suppose this runway is used for arrivals only. Find its maximum throughput capacity for arrivals. (Include BT) 3. Calculate the arrival capacity in 2 assuming the separation requirement between Large and Small class is changed from 4 to 4*.

Answer rating: 100% (QA)

ANSWER Here are the solutions 1 Runway capacity for departures only Heaviest aircraft type H has the longest separation requirement of 120 seconds from other aircraft In one hour there are 3600 second... View the full answer
