Differentiate between Airside and Landside.

Airside and landside are terms used to distinguish different areas within an airport, each serving specific functions related to aviation operations and passenger services:

Airside:
The airside of an airport refers to the secure area beyond the security checkpoints, including runways, taxiways, aprons, and other facilities directly involved in aircraft operations. Only passengers with valid boarding passes and airport staff with relevant security clearance are permitted to access the airside. The airside is where aircraft are parked, loaded, and unloaded, and it is restricted to those directly involved in flight operations.

Landside:
The landside of an airport includes areas accessible to the public and passengers before passing through security checks. It encompasses terminals, check-in counters, baggage claim areas, public transportation facilities, parking lots, and other amenities for passengers and visitors. Landside is where passengers arrive, check in for their flights, go through security screening, and access services and facilities provided by the airport. Unlike the airside, landside areas are open to the general public, including those not traveling by air.

In summary, the airside is the secure area dedicated to aircraft operations, while the landside includes publicly accessible areas catering to passenger services and facilities.
