1. Airside
Definition:
The airside of an airport encompasses all operational areas where aircraft move and receive service. This includes runways, taxiways, aprons, and the surrounding terrain, as well as support facilities like hangars and fuel farms. Access is tightly regulated for safety and security. According to ICAO Annex 14
, airside is the “movement area” plus any adjacent terrain and buildings not accessible to the public.
Key Features:
- Boundaries: Typically marked by fences, gates, and security checkpoints.
- Facilities: Runways, taxiways, aprons, hangars, fuel farms, fire stations, cargo terminals.
- Excludes: Public areas such as terminal buildings, ticketing, and parking.
- Access: Controlled by identification cards, biometric readers, vehicle passes, and surveillance.
- Operational control: Managed by airport authorities, air traffic control, and security agencies.
- Purpose: Ensure safe, efficient, and secure aircraft operations.

2. Landside
Definition:
Landside is the publicly accessible part of the airport, which includes ticketing areas, baggage claim, parking, public transport, and retail. No security clearance is needed.
Key Points:
- Functions: Passenger processing, public transportation, commercial services.
- Boundary: Separated from airside by security checkpoints, doors, or fences.
- Transition: Security screening points mark the move from landside to airside.
References:
3. Runway
Definition:
A runway is a designated, paved rectangular area for aircraft takeoff and landing. It is constructed to specific international standards for strength, markings, and lighting.
Features:
- Markings: Numbers for magnetic heading, threshold, centerline, touchdown zone.
- Lighting: Edge, centerline, threshold, approach lights, and REILs.
- Runway Safety Area: Graded extension for overrun protection.
- Protection Zone: Off-limits to non-essential persons and vehicles.
References:
4. Taxiway
Definition:
A taxiway is a path for aircraft to move between runways, aprons, hangars, and other facilities at low speeds.
Features:
- Markings: Yellow centerline and edge lines, hold short lines.
- Lighting: Blue edge lights, green centerline lights (for low-visibility).
- Naming: Letters and numbers for communication.
- Signage: Directional and location signs for pilots and vehicles.
References:
5. Apron (Ramp)
Definition:
The apron (or ramp in the US) is the area where aircraft are parked for loading, unloading, fueling, and minor servicing.
Features:
- Aircraft stands: Marked parking spots.
- Ground Support Equipment: Belt loaders, tugs, fuel trucks.
- Jet bridges: Enclosed walkways at terminal gates.
- Safety zones: Marked areas to keep clear of engines and propellers.
- Apron lighting: Floodlights for night operations.
References:
6. Aircraft Stand
Definition:
An aircraft stand is a specifically marked area on the apron where aircraft are parked for servicing, boarding, and loading.
Types:
- Contact stand: Located at terminal, accessible by jet bridge.
- Remote stand: Away from terminal, accessed by bus or stairs.
- Service stand: For overnight parking or maintenance.
Features:
- Marked lead-in lines, safety zones, ground power units.
References:
7. Hangar
Definition:
A hangar is a large enclosed building for storing, maintaining, or repairing aircraft.
Features:
- Fire suppression, high-strength floors, cranes, large access doors, environmental controls.
Uses:
- Routine checks, heavy maintenance, long-term storage.
References:
8. Fuel Farm
Definition:
A fuel farm is a secure area where aviation fuels are stored and distributed to aircraft.
Components:
- Storage tanks, pumps, filtration, hydrant network, control room, emergency systems.
Access:
- Strictly limited to trained personnel, with CCTV and regular inspections.
References:
9. Fire and Rescue Station
Definition:
The fire and rescue station (ARFF) is responsible for emergency response to aircraft incidents and fires on airside.
Features:
- Specialized vehicles, rescue tools, medical kits, foam/water systems.
- Strategically located to meet ICAO response time requirements.
References:
10. Cargo Facility
Definition:
A cargo facility is an airside area for handling, screening, and transferring air freight and mail.
Features:
- Cargo terminals, security fencing, specialized storage, ramp access.
Operations:
- Staff require security checks and airside training. Goods are screened per ICAO Annex 17.
References:
11. ATC Tower
Definition:
The Air Traffic Control (ATC) tower is the operational center that manages aircraft and vehicle movements on the ground and in the immediate airspace.
Functions:
- Ground control, tower/local control, and sometimes apron control.
- Uses radar, radio, and lighting systems for safety and coordination.
References:
12. Access Control
Definition:
Access control systems and procedures restrict, monitor, and authorize entry to the airside.
Elements:
- Security checkpoints, electronic readers, biometric gates, vehicle screening, CCTV.
References:
13. Security Restricted Area (SRA)
Definition:
The Security Restricted Area (SRA) is the core airside zone with the highest security, containing aircraft and critical infrastructure.
Access:
- Requires operational need and clearance, with strict screening and monitoring.
References:
14. Critical Part of SRA (CPSRA)
Definition:
The Critical Part of the Security Restricted Area (CPSRA) is the most sensitive part of the SRA, typically around aircraft and essential operations.
Access:
- Limited to essential personnel with the highest clearance. Enhanced screening and monitoring apply.
15. Demarcated Area
Definition:
A demarcated area is a temporarily or permanently segregated airside zone for special operations, such as VIP movements or construction.

16. Airside Identification Card (AIC)
Definition:
An Airside Identification Card (AIC) is an official ID credential for authorized personnel needing airside access.
