ves ane (d) Try to develop an alternative sequence that lands all of the aircraft safely and reduces the total cost. ATCS provides training for future air traffic controllers. One of the skills air traffic controllers need is the ability to sequence aircraft for landing purposes. The control- ler decides who lands immediately and who goes into a holding pattern. The following data are provided to you, the student, to develop an acceptable landing sequence. Any sequence that results in an aircraft not being sched- uled to land before it runs out of remaining flying time is unacceptable. The following aircraft are currently await- ing your decision as to their landing sequence. Remaining Cost per Flight Minutes Flying Time Minute of Number on Runway (minutes) Flying Time ($) 101 2.00 10 100 118 3.00 15 150 217 2.75 8 125 8076 1.50 5 80 219 3.50 12 200 894 1.75 19 150 024 2.50 16 400 616 3.25 22 300 There are many ways to sequence this group of aircraft waiting to land. Since cost is an obvious fac- tor, consider a sequence that minimizes total cost to land the aircraft. Multiply the cost per minute of flying time by the remaining number of minutes. This gives you the maximum cost associated with an airplane
