• Compare the cost of delay for operating a Boeing 737-800 with an Airbus A320 and explains the reasons for the cost difference. With the tasks of calculating the delay cost for a Boeing 737-800 and compare it with the Airbus A320, certain procedures must be followed. But first, what is the definition of delay, and based on the report, it is stated that various definitions can be used when considering aviation delays. For the purposes of the study, the default definition adopted is that of an aircraft's off-block/on-block time relative to the operator's published schedule. The decision to take into account delays to the published schedule was made primarily because it is by far the easiest metric to quantify and the most commonly adopted metric in the industry. However, the delay is measured in relation to the last flight plan filed. Delay costs are calculated at the tactical and strategic levels for different aircraft types and cost scenarios, and then at the higher level of the European network. For a plane to be delayed on the ground or in flight, it means losing revenue in g...
