Comprehensive Airport Planning Study Guide

I. The Master Plan & Basics

  • Airport Master Plan (AMP): An Airport Master Plan is defined as a long-term strategy for development designed to meet future aviation demand. It typically encompasses a Planning Horizon spanning 2020 years, which is further subdivided into short-term, medium-term, and long-term phases.
  • Primary Goal: The central objective of an AMP is to provide a comprehensive framework for efficient land use and the development of airport facilities.
  • Regulatory Oversight (FAA/ICAO): Global standards for airport planning are provided by two main bodies:
    • FAA: Federal Aviation Administration.
    • ICAO: International Civil Aviation Organization.
  • ALP (Airport Layout Plan): This is a graphic representation of both existing and future facilities. It is considered the most critical document for securing funding for airport projects.
  • Stakeholder Engagement: Process involve multiple parties including airlines, local government, passengers, and the broader community.
  • Socio-economic Impact: Planning acknowledges that airports serve as regional economic engines, impacting the surrounding socio-economic landscape.
  • Site Selection Criteria: The selection of an airport site is based on several factors:
    • Airspace availability.
    • Land availability.
    • Environmental impact.
    • Ground access.
  • Capacity Definitions:
    • Capacity: The maximum number of aircraft or passengers an airport can handle within a specific period.
    • Throughput Capacity: The rate at which aircraft can be handled without violating safety rules.
    • Practical Capacity: The level of operations where delay is maintained at a tolerable limit.
  • Delay: Defined as the difference between the actual time and the 'ideal' time of a movement.
  • Demand Forecasting: The process of predicting future movements related to passengers, cargo, and aircraft.
  • Activity Indicators: These include enplanements, aircraft operations, and air cargo tonnage.
  • Public Hearing: This is a legal requirement for major updates to the master plan, functioning as a mechanism to gather feedback from the community.

II. Airside Design & Runways

  • Airside: This refers to the 'secure' portion of the airport, containing critical infrastructure such as runways, taxiways, and aprons.
  • Runway Orientation: This is determined primarily by the prevailing wind directions in the area.
  • Wind Rose: A graphic tool utilized during the planning phase to determine the optimal runway orientation to maximize the usability of the airport.
  • Crosswind Component: The wind vector that is perpendicular to the runway. Specific crosswind limits apply based on different aircraft sizes.
  • Runway Thresholds:
    • Runway Threshold: The start of the portion of the runway that is usable for landing.
    • Displaced Threshold: A threshold located downwind from the physical end of the runway pavement, typically implemented to ensure obstacle clearance.
  • RSA (Runway Safety Area): A prepared surface surrounding the runway designed to reduce the risk of damage if an aircraft undershoots or overruns the runway.
  • Stopway: A designated area beyond the runway used to decelerate an aircraft during an aborted takeoff.
  • Clearway: An area extending beyond the runway where an aircraft can conduct its initial climb.
  • Runway Configuration Types:

    • Far: Spacing greater than 4,300 ft4,300\,ft.
  • Taxiways: Defined paths for aircraft movement between the runways and the apron.
  • Exit Taxiway: Designed specifically to allow aircraft to vacate the runway quickly. High-speed exits are usually designed at a 30∘30^{\circ} angle.
  • Apron (Ramp): The area where aircraft are parked, fueled, and loaded. Within the apron, Taxilanes are utilized as parts of the apron to provide access to gates.
  • Pavement Strength (PCN/ACN):
    • PCN (Pavement Classification Number): Indicates the strength of the pavement.
    • ACN (Aircraft Classification Number): Indicates the specific effect an aircraft has on the pavement.
  • Critical Aircraft: The most demanding aircraft type that performs at least 500500 annual operations at the airport, used to dictate design standards.
  • Markings and Lighting:
    • Runway Markings: These are white in color.
    • Taxiway Markings: These are yellow in color.
    • PAPI/VASI: Visual light systems providing glide slope guidance (Precision vs Visual).
    • ILS (Instrument Landing System): Provides both horizontal and vertical guidance for landing during conditions of low visibility.
  • Operational Safety:
    • FOD (Foreign Object Debris): Any object located on the airside that has the potential to damage an aircraft.
    • Wildlife Management: Planning efforts to mitigate hazards such as bird strikes near flight paths.

III. The Terminal Area

  • Terminal Functions: The terminal is divided into functions of Processing (check-in and security), Circulation, and Waiting (such as lounges).
  • Terminal Design Concepts:
    • Linear Concept: Gates arranged along a straight line.
    • Pier (Finger) Concept: Extends from a main building; efficient but can result in long walking distances for passengers.
