Airside Signage
![Page 3: Lecture 2: AIRSIDE](https://reader033.vdocuments.mx/reader033/viewer/2022061423/56815c27550346895dc9fc3c/html5/thumbnails/3.jpg)
Signage
• Airside guidance signs provide direction and information to taxiing aircraft and any vehicles and assist in safe movement of aircraft.
![Page 4: Lecture 2: AIRSIDE](https://reader033.vdocuments.mx/reader033/viewer/2022061423/56815c27550346895dc9fc3c/html5/thumbnails/4.jpg)
Importance of the Signs
• To show mandatory instructions, information on a specific location or destination in the aerodrome.
• Characteristics of signs:• Clear• Rectangular• Different colors for each category• Illuminated (light up)

guidance signs
Direction signs: To indicate the intersection for aircraft turning.
Destination signs: To show direction to the specific destinations (cargo areas, military areas, international areas, etc.)
Mandatory signs:To indicate that aircraft ARE NOT ALLOWED to
enter (runway entrance & critical areas)
Location signs:To identify aircraft location.
Runway distance remaining signs: Landing distance remaining

Weather Information
![Page 9: Lecture 2: AIRSIDE](https://reader033.vdocuments.mx/reader033/viewer/2022061423/56815c27550346895dc9fc3c/html5/thumbnails/9.jpg)
Airport Weather Stations
• Every 20 minutes• Observes temperature,
wind speed & direction, visibility, cloud coverage.
• Can’t observe sudden weather change.
• Automated Weather Observing Systems (AWOS)
• Automated Surface Observing Systems (ASOS)
• Every 1 hour• Observe weather conditions change rapidly.• Current weather, icing, lightning,, air
pressure.

Wind Sock
• To Indicate wind direction & speed.• The stronger the wind, the
straighter the wind sock.• Move back and forth when the
wind is gusty.
• To Indicate wind direction only.• To suggest the pilot the runway
to be used
Wind Tee
Guiding pilot to determine the correct runway to use for landing and take off

What are the Importanceof Weather Detector?
• To prevent aircraft accidents.• To avoid flight delay or cancellations.• To make management of the air routes more
efficient• To improve the safety of the aircraft in the air.

Navigational Aid Systems
![Page 14: Lecture 2: AIRSIDE](https://reader033.vdocuments.mx/reader033/viewer/2022061423/56815c27550346895dc9fc3c/html5/thumbnails/14.jpg)
Navigational Aid Systems• There are a number of navigational aids available in
Airports.• A Visual Approach Slope Indicator (VASI): helps pilots fly a
perfect approach for landing once they have found the airport.
• VHF Omni directional range (VOR) to help pilots find the direction to the airport.
• Distance Measuring Equipment (DME) to determine the distance to the airport.
• Instrument Landing System(ILS) to find the runway and fly the correct approach, even if they cannot see the ground.

Aerodrome Reference Code
• The aerodromes are coded according to the physical requirements of the critical aircraft
• The aerodrome facilities must meet physical requirements of the critical aircraft
![Page 20: Lecture 2: AIRSIDE](https://reader033.vdocuments.mx/reader033/viewer/2022061423/56815c27550346895dc9fc3c/html5/thumbnails/20.jpg)
Aerodrome Reference Code (ARC)
ARC is determined by two factors:Code number (1,2..,4) to reflect aircraft operating
performance in terms of balanced field length of runways
• Airplane reference field length (RFL)Code letter (A, B, ..,F) to reflect the aircraft physical
dimensionsWing span (WS)

![Page 21: Lecture 2: AIRSIDE](https://reader033.vdocuments.mx/reader033/viewer/2022061423/56815c27550346895dc9fc3c/html5/thumbnails/21.jpg)
Aerodrome Reference Code (ARC)• Airplane reference Field Length (RFL): The
minimum field length required for take-off at maximum certificated take-off mass.
• Wing Span (WS)= the maximum extent across the wings of an aircraft
