Runway Markings
• Runway Threshold: Helps identify the beginning of
the runway that is available for landing.
• Runway Designators: Shows the magnetic heading
• Runway Centerline Marking: Provides alignment
guidance during takeoff and landings.
• Runway Aiming Point Marking: Serves as a visual
aiming point for a landing aircraft.
• Runway Touchdown Zone Markers: Identify the
touchdown zone for landing operations
10
RWY Designators
• Identified by a two digit number according to their
magnetic heading.
• The angle is measured from magnetic north and is
divided by 10 and rounded to the nearest integer.
• Example: RWY with a magnetic heading of 340° is
marked as RWY 34.
• Each runway can be used in either direction, and
hence has two numbers, each 18 apart.
• Example: (34-18=16), so the other runway marked
as RWY 16
11
RWY Designators
• Each digit is pronounced separately for clarity in
radio communications. Example: Runway 36 is
pronounced as Three Six.
• For two parallel RWYs, R for Right and L for Left are
added to distinguish btw the RWS.
• For multiple runways each runway is identified by
Left (L), Center (C) and Right (R).
• Example: 26L and 26R.

O’Hare International Airport –
Chicago, Illinois, United States
Munich Airport:
Two Parallel Runways
Runways Length
• Runway lengths depend on the size of aircraft
to operate and the weather conditions.
• The bigger the aircraft the longer the runway
(take-off and landing distances)
• The hotter the weather the longer the runway
• **The longest public-use runway in the world is at Qamdo
Bangda Airport in China. It has a length of 5,500 m (18,045
ft).
• **The world’s widest paved runway is at Ulyanovsk
Vostochny Airport in Russia and is 105 m (344 ft) wide.
19
Runways Length
• For aircraft weights below approximately
90,718 kg, a runway length ~ 1,829 m
• Larger aircraft (Boeing 747, 767, 777, and
787; Airbus A300, A330, A340, A350, and
A380; McDonnell Douglas DC-10 or MD-11;
and the Lockheed L1011) will usually require
runway length at least 2,438 m.

Runway Lighting Summary
Importance of Lighting
Lighting systems are important for
a/c landing during night time.
Lighting systems from the cockpit
window during bad weather.
Poor visibility is mainly due to
heavy snowfall
Runway Lighting
Lighting systems from the cockpit window
Runway Edge
Lighting:
•White
•Turn Yellow in
last 610m
Runway Center line
Light System :
•White
•Alternate white and
red in last 610 m
•Red in last 310m
Why the lighting colour change?
23
Runway Pavements
• The surface sections of roads and runways are
known as “pavements”.
• To serve its purpose, a pavement must have
adequate load-carrying capability, good ride
ability and must allow safe operation of
aircraft.
Concrete Pavement
• Concrete surfaces from 23
to 40 cm (9 to 16 inches)
thick.
• Can remain useful for 20 to
40 years.
• Commonly used at large
airports.
• It is constructed by aligning
a series of concrete slabs
connected by joins,
Asphalt Pavement
• Asphalt surfaces are from 5
to 10 cm (2 to 4 inches)
thick.
• Can remain useful between
15 to 20 years.
• Commonly used at most
smaller airports.
• Pavements are less
expensive to construct.
Taxiway
26
2. Taxiway
• Strip for aircrafts to move slowly
(taxi) between the runway and
apron, runway and runway &
apron and apron.
27
Taxiway
•
•
•
•
Generally, width smaller than runway
Lightings for night flying
Can be one or multiple in bigger airport.
Taxiways should be provided to permit the safe
surface movement of aircraft.
• Sufficient entrance and exit taxiways for a
runway should be provided to make the
movement of airplanes to and from the runway
smooth and to provide more rapid exit taxiways
when traffic volumes are high.
28
Taxiway Types
29
Taxiway Types
There are four types of taxiways:
• Parallel taxiways: aligned parallel next to runway
• Entrance taxiways: perpendicular to the runway &
located near the departure end of runways.
• High-speed taxiways: to allow aircraft quickly free-up
the runway. (Also known as Rapid Exit) , located at
various points along the runway to allow landing
aircraft to efficiently exit the runway after landing.
• By-pass taxiways: located near apron, to allow
aircraft by-pass other aircraft at aircraft parking area.
30
High-speed taxiways
• Also known as Rapid Exit runway.
• To provide exit paths from runway for arriving
aircraft.
• The intersection angle less than 90deg.
31
Taxiway Identification
Taxiways can be identified through:
• Taxiway markings (centerline in yellow color, no
azimuth)
• Taxiway signs (have location sign)
• Taxiway lightings (centerline light in green color,
edge light in blue color)
• Taxiway size and pavement strength (width smaller
than runway, pavement thickness less than runway)
32
Taxiway Lighting
Taxiway
centre line:
green
Taxiway edge
lights: blue
Taxiway Lighting
• Many airports are equipped with taxiway lighting
to facilitate the movement of aircraft on the
airfield at night or in poor visibility conditions.
• Taxiway lighting includes taxiway edge lights,
taxiway centerlines lights.
Taxiway Markings
Taxiway
Centerline
• Taxiway Centerline : single
continuous yellow line .
• All taxiways should have
centerline markings.
• Aircraft should be kept
centered during taxi to
guarantee wingtip
clearance with other
aircraft or other objects
Taxiway Markings
Surface Painted Signs: to assist pilot in confirming
the designation of the taxiway (location or
direction)
Surface Painted Signs
37
RWY/TWY Markings
What The Importance of
RWY/TWY Markings?
• To provide information that is useful to a pilot
during takeoff, landing, and taxiing.
• To enhance safety and improve efficiency: Same
airport markings for all airports make pilots
became familiar.
APRON
40
3. APRON
• An area to accommodate aircraft for
purposes of parking , loading or unloading
passengers, mail or cargo, fuelling, or
41
maintenance.
3. Apron
• Also known as RAMP
• Apron sizes depend on the aircrafts handled
by the airport.
• The bigger the airport handling capacity the
bigger the apron
• Provide FBO services
• Fitted with underground refueling system
• Fitted with water supply system
• Fitted with sewer disposal system
42
Fixed Base Operators
(FBO)
• The FAA defines an FBO as A commercial
business granted the right by the airport
sponsor to operate on an airport and provide
aeronautical services such as fueling,
hangaring, tie-down and parking, aircraft
rental, aircraft maintenance & flight
instruction, etc
