DEVELOPING AN AIRPORT MASTER PLAN When operators introduce an airplane model into their fleets, they need to work closely with airport authorities and airplane manufacturers to ensure airport configurations can accommodate the airplane. Airplane characteristics — such as increased wingspan, fuselage length, or weight — affect ground maneuverability, pavement loads, and terminal servicing. Any incompatibility between the configuration of the airport and the characteristics of the airplane must be resolved long before the airplane arrives at the airport to ensure successful operation and profitability for the airline. The case for advanced planning is strong because major airport changes, such as terminal redevelopment, require 10 to 20 years to complete. AERO EDWARD L. GERVAIS, P.E. AIRPORT TECHNOLOGY FACILITIES TECHNICAL FELLOW BOEING COMMERCIAL AIRPLANES GROUP 15 An airport master plan combines aviation growth projections with future airplane capabilities to create a detailed plan and schedule for a given airport. It defines both the immediate and long-term needs of an airport facility in logical growth increments that include airport configuration, uses, and costs. An effective plan maximizes the development potential of the facility and allows for the appropriate budgeting and timing for engineering, design, and construction. In developing an airport master plan, airports, airlines, and airplane manufacturers should consider the following factors to ensure safe and efficient airplane operations: 1. Aviation industry forecasts and growth projections. 2. General airport planning guidelines. 3. Specific airplane requirements. 4. Airport terminal requirements.
