Airport technical services provide for the safety of aircraft operations through air traffic services, aeronautical telecommunications, meteorology, and aeronautical information services. Air traffic services include air traffic control which prevents collisions and promotes efficient air traffic flow. Aeronautical telecommunications provides fixed, mobile, radio navigation, and broadcasting services. Meteorology services interpret weather data and provide observations. Aeronautical information services provide information on air traffic requirements and publish the Aeronautical Information Publication and notices to airmen.

1. Airport
Technical
Services

2. AIRPORT TECHNICAL SERVICES
It concerned with the safety of aircraft operations in terms of
control, navigation, communications and information. Clearly these
matters subjected to the technical annexes (ICAO 1990, ICAO
1991, ICAO 1992, ICAO 1993).
SERVICES:
 Air Traffic Services
 Aeronautical telecommunications
 Meteorology
 Aeronautical information services

3. 1. AIR TRAFFIC SERVICES
(Air Traffic Controller)
 serves the function of prevention of collision between aircraft
in-flight and between aircraft in any obstructions
(moving/stationary) on an airport.
Promotes efficient air traffic flow
Administered/Manages in governmental/quasi-governmental
agency
Responsible for en route airspace exercising control from
regional centers

4. TYPES OF AIR SPACE
Uncontrolled airspace
is an airport with no operating tower, or air traffic control unit. The vast
majority of the world's airports are non-towered, and even airports with control
towers may operate as non-towered during off-hours, typically during the night.

5.  Controlled Airspace
is airspace of defined dimensions within which ATC services are provided. The
level of control varies with different classes of airspace. Controlled airspace
usually imposes higher weather minimums than are applicable in uncontrolled
airspace.

6. These are three sets of flight rules depending on the circumstances:
• General Flight Rules – observed by all aircraft in whatever type of
airspace
• Visual Flight Rules (VFR) – observed by aircraft flying in weather
conditions above prescribed limits
• Instrument Flight rules (IFR) – observed by aircraft in weather
conditions below visual limits and/or in certain categories of airspace
Flight Rules

7. 2. AERONAUTICAL TELECOMMUNICATIONS
(including NavAids)
 the provision and maintenance of suitable aviation communication and
navigation equipment and facilities are worldwide requirements for Civil Aviation
SERVICES:
1. Fixed Services
2. Mobile Services
3. Radio navigation services
4. Broadcasting services

8.  Fixed Services
Fills the need for the rapid means of point-to-point ground communications
between “fixed” points (either by cable or radio link) to Air Transport and General
Aviation (passes messages relating to safety, regular, efficient and economical
operation based on the Aeronautical Fixed Telecommunications Network –
AFTN)
CATEGORIES OF MESSAGES:
1. Distress messages and distress traffic
2. Flight Safety
3. Meteorological
4. Flight Regularity
5. Aeronautical Administration
6. NOTAM Class I distribution
7. General Aircraft Operating Agency

9.  Mobile Services
Services provided for aircraft (Moving Air/ Ground Vehicles), but facilities
are primarily fixed/ installed on the ground. The mobile services covers two
vital aspects of aircraft movements:
(1) Communication
(2) Navigation
PROVIDES:
1. Flight Information Service
2. Alerting Service
3. Air Traffic Advisory Service
4. Air Traffic Control Service
5. Area/ Airways Control Service
6. Approach Control Service
7. Airport Control Service

10. Radio Navigation Services
Radio Navigation Approach and landing guidance that requires a
precision-approach aid
• VOR
•TVOR
•DME
•VHF
•VFR
•ILS

11. Broadcasting Services
 provides information on weather and airport and radio aids
serviceability
 provides suitable broadcast facilities that publishes detail of
frequencies used and times of broadcast
 (Automatic Terminal Information [ATIS] – most common type of
broadcast concerned with airport operations)
 Identified by individual phonetic letters
 provides and repeats information on Surface Wind and Prevailing
Weather (until change takes place); for arriving and departing aircraft
 informs and reduces amount of traffic on the vital control
frequencies
 Initial ATIS voice contacts to destination airport
 Pilot advices “Information Sierra Received”

12. 3. Meteorology Services
 interpret weather data and forecasts in light of own airline
operational plans.
 observes, reports and advises on weather conditions on the
ground at airports and in the upper atmosphere. (routine, hourly, or
half-hourly)
ICAO corresponding types of messages:
(1)METAR – Aviation Routine Weather Report
(2)SPECI – Aviation Selected Special Weather Report

13. REPORTS CONTENTS:
1. Identification
2. Surface Win Direction and Speed
3. Visibility/CAVOK
4. RVR – when appropriate (Runway Visual Range)
5. Present Weather
6. Cloud – amount and type
7. Temperature and Dew Point
8. QNH – Altimeter Pressure Setting
9. Trend Forecast

14. 4. Aeronautical Information Services
 provides information on air traffic control requirements, airport layout, hours of
operation and availability of fuel
 follows ICAO international product format
 responsible for the:
a. Preparation of an Aeronautical Information Publication (AIP)
b. The origination of NOTAMs
c. The origination of the Aeronautic Information Circulars

15. CONTENTS OF AIP
1. GEN (General) – description of AIS
2. AGA (Airports) – description of provisions for facilities,
services and ground aids for international air navigation;
International Airports; Airports Available fir International
Commercial Air Transport; Airport Directory and Airport Ground
Lights;
3. COM (Communications) – Description of provisions for
communication services
4. MET (Meteorology) – Description of provisions for
Meteorological Services

16. 5. RAC (Rules of the Air and Air Traffic Services) – Description of
Air Traffic Services provided, and where necessary, graphics of
FIRs and divisions of airspace
6.FAL (Facilitation) – Description of provisions for facilitation if
international air navigation
7.SAR (Search and Rescue) – Provisions for search and rescue
system and procedure
8.MAP (Aeronautical Charts Published) – Description of
