Problem #1
- Assume normal, good weather capacity and a 70% passenger load factor. Using the attached Excel exercise, what are the per plane delay times and operational and passenger delay costs associated with arrival rates of 50 planes per hour, for all three types of planes mentioned? At 55 planes per hour? At 59?
Delay Dollars per person per hour | # People at 70% Load | Pure Delay Cost / hour | Total Delay Cost / hour | Total Delay Cost / minute | |
Turboprop | $25.70 | 13.3 | $348.00 | $689.81 | $11.50 |
Regional | $25.70 | 35 | $640.00 | $1,539.50 | $25.66 |
Conventional | $25.70 | 105 | $1,585.00 | $4,283.50 | $71.39 |
Per plane delay times and total delay costs per plane
Arrivals / hour | 50 | 55 | 59 |
Expected Delay (from above) (min) | 6.54 | 12.52 | 60.5 |
Turboprop | $75.19 | $143.94 | $695.56 |
Regional | $167.81 | $321.24 | $1,552.33 |
Conventional | $466.90 | $893.82 | $4,319.20 |
50 planes/hour:
– Turboprop: (6.54/60) * 348 + (6.54/60) * 25.7 *13.33 = $75.19
– Regional jets: (6.54/60) * 640 + (6.54/60) * 25.7 *35 = $167.81
– Conventional jets: (6.54/60) * 1585 + (6.54/60) * 25.7 * 105 = $466.90
55 planes/hour:
– Turboprop: (12.52/60) * 348 + (12.52/60) * 25.7 * 13.33 = $143.94
– Regional jets: (12.52/60) * 640 + (12.52/60) * 25.7 * 35 = $321.24
– Conventional jets: (12.52/60) * 1585 + (12.52/60) * 25.7 * 105 = $893.82
59 planes/hour:
– Turboprop: (60.5/60) * 348 + (60.5/60) * 25.7 * 13.33 = $695.56
