NEXTOR - National Center of Excellence for Aviation Research 2 Material Presented in this Section Review of aircraft cost models (supply costs in air transportation) How supply of service affects the operational economics of the service Apply aircraft performance functions to derive supply relationships

NEXTOR - National Center of Excellence for Aviation Research 3 Aircraft Supply Cost Modeling Supply function costs are a very important component in the analysis of air transportation systems Supply costs are driven by the economics of the aircraft used, the network structure of the service provider (degree of “hub consolidation”), labor costs, etc. Two views of the world to derive supply costs in air transportation: - Fare-based models - Life-cycle cost models based on actual information about organizational cost components

NEXTOR - National Center of Excellence for Aviation Research 5 Fare-Based Models Look into the public record and attempt to capture the average fare paid by users in a given air transportation segment No attempt made to evaluate individual costs of providing service Fares vary dramatically in NAS (specially for airline- type operations) These models have appeal because they are simple to derive once you have good access to the fare data Best sources of data: airline bookings, DOT BTS DB1B data (go to http://transtats.bts.org)

NEXTOR - National Center of Excellence for Aviation Research 6 Fare-Based Models We provide you with a sample fare-based model developed at Virginia Tech to predict commercial airline costs across NAS This work is part of an integrated transportation systems assessment plan to evaluate new NASA concepts like SATS - Small Aircraft Transportation System The model has also been used in mode split analysis calibration for the FAA NAS Strategy Simulator (recently)

NEXTOR - National Center of Excellence for Aviation Research 7 What is the DB1B Database? A 10% sample of tickets sold in the country by carriers Only a sample (so be aware of possible errors in low density markets) Collected by DOT and published by the Bureau of Transportation Statistics (BTS) at http:// transtats.bts.org Three types of records are collected: - Coupon - Market - Ticket

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
