RUNWAY TAXIWAY APRON
RUNWAY
• The place for aircraft to
take off and landing
• The dimension depends
on the characteristics of
the biggest aircraft served
in the related airport
• The direction of the
runway depends on the
prevailing wind
TAXIWAY
• Taxiway facilitates aircraft to taxi the aircraft to apron
• Taxiway is connected to runway by exit taxiway, rapid exit
taxiway, and holding apron.
• Taxiway design depends on the aircraft reference code
APRON
• Apron is a parking area for aircraft
• The activities in apron includes loading/unloading
passengers/baggages, cleaning, checking, refueling,

CURBSIDE PROCESSING WAITING
AREA LOUNGE
CURBSIDE
• The place for changing mode of transport
• Loading /unloading passengers and baggage from and to
land transport (private cars, taxi, bus)
PROCESSING AREA
• Screening, Check-in,
immigration (for
departure passengers)
• Immigration, custom,
baggage claim (for
arrival passengers)
WAITING LOUNGE
• Waiting room
• Restaurants
• Shops
Access To Airport
Access to the airport
ROAD/RAIL MODE SHARE
NETWORK
Roads Network
• Road network should
offer quick, easy access
to the airport
• The road network
provides a more
uniformly-concentric
and ‘predictable’ level
of accessibility
compared to public
transport.

Landing Gear
Traditional and complex landing gear configurations (Federal
Aviation Administration)
Relevance of Aircraft Characteristics
• Aircraft classification are useful in airport engineering
work (including terminal gate sizing, apron and taxiway
planning, etc.) and in air traffic analyses
• Most of the airport design standards are related to
aircraft size (i.e., wingspan, aircraft length, aircraft
wheelbase, aircraft seating capacity, etc.)
• Airport fleet compositions vary over time and thus is
imperative that we learn how to forecast expected
vehicle sizes over long periods of time
• The Next Generation (NextGen) air transportation
system will cater to a more diverse pool of aircraft
Typical Dimension of Large Aircraft
Typical Dimension of Small Aircraft
CMG Distance vs Wheelbase Distance
Consideration About CMG Distance vs Wheelbase
Distance
• FAA specifies:
• Cockpit to Main Gear (CMG) dimension will be used
instead of the aircraft wheelbase for aircraft where the
cockpit is located forward of the nose gear (typically
applies to commercial aircraft)
• For aircraft with the cockpit located aft of the nose gear,
use the wheelbase instead of CMG to determine the
Taxiway Design Group (TDG)
• See figures in the previous slides
CMG Distance vs Wheelbase Distance
• Most general aviation aircraft (called GA) typically
have the nose gear located in front of the cockpit (use
the wheelbase distance for design)
CMG Distance vs Wheelbase Distance
• Most commercial aircraft have the cockpit located
ahead of the nose gear (use CMG distance)
CMG Distance vs Wheelbase Distance
Some aircraft have special landing gear configurations

Physical Characteristics
(Chapter 6 Horenjeff)
RUNWAY
Characteristic Runway
• For design purposes, airports are classified based on
the aircraft they accommodate.
• Airports are designed based on a series of “critical” or
“design” aircraft.
• The FAA defines the term critical aircraft as the aircraft
most demanding on airport design that operates at
least 500 annual itinerant operations at a given airport.
• The smallest aircraft that is critical to the orientation of
runways,
• The largest aircraft determines most of the other
dimensional specifications of an airfield.
Characteristic Runway
• Dimensional and performance characteristics of the
critical aircraft determine the airport’s airport
reference code.
• The airport reference code is a two designator code
referring to the aircraft approach category and
the airplane design group for which the airport
has been designed.
• The airplane design group (ADG) is a grouping of
aircraft based upon wingspan or tail height

Runway System Geometric Specifications
Graph (a)
• The runway structural pavement supports the
aircraft with respect to structural load,
maneuverability, control, stability, and other
operational and dimensional criteria.
• The shoulder adjacent to the edges of the
structural pavement resists jet blast erosion and
accommodates maintenance and emergency
equipment.
• The blast pad is an area designed to prevent
erosion of the surfaces adjacent to the ends of
runways due to jet blast or propeller wash.
Graph (b)
• The runway safety area (RSA) is an area
surrounding the runway prepared or suitable for
reducing the risk of damage to aircraft in the event
of an undershoot, overshoot, or excursion from the
runway.
• The runway safety area includes the structural
pavement, shoulders, blast pad, and stop-way, if
provided.
Graph (c)
• The runway object-free area (OFA) is defined by
the FAA as a two-dimensional ground area
surrounding the runway which must be clear of
parked aircraft and objects other than those whose
location is fixed by function.
Graph (d)
• The runway protection zone (RPZ) is an area
on the ground used to enhance the protection of
people and objects near the runway approach.

APRON
Aprons
Holding Aprons
• Holding aprons, holding pads, run-up pads, or
holding bays as they are sometimes called, are
placed adjacent to the ends of runways.
• The areas are used as storage areas for aircraft
prior to takeoff.

REMARKS
• Airport Layout depends on
• Name any part of airport and its function
• How do we determine the physical characteristics of
airport parts
• How do we distinguish the airport category
• Why do we need to understand the aircraft
characteristics
