The traffic volume in the year 2018 at an airport (number of take-offs and landings) during peak hour of each day is a described as a log-normal random variable with a mean of 200 planes and a standard deviation of 60 planes. a. If the present runway capacity (for landings and take-offs) is 350 planes per hour, what is the current probability of congestion? [2 marks] b. If the mean traffic volume is increasing linearly at the annual rate of 10% of the volume in 2018 with the coefficient of variation remaining constant what would be the probability of congestion at the airport in year 2028? [2 marks] c. Assuming the same projected growth rate of traffic volume as part (b), and that the maximum acceptable probability of congestion is 10% what year will the airport need to increase their runway capacity? [4 marks] d. Assuming the same projected growth rate of traffic volume as part (b) when the airport upgrades their runway capacity in part (c) what new runaway capacity will they need to ensure the probability of congestion does not exceed the max acceptable probability of congestion of 10% until year 2038? [2 marks]
