Passengers

Passengers, also known as PAX in-game, are a type of payload in Extreme Landings Pro.

Description
They are not visible within the aircraft, and they are not physically seen in the game, but are obviously intended to represent people being transported by a passenger aircraft.

There is no game progression-related purpose, but they can make aircraft heavier and more prone to unresponsiveness or longer takeoff runs.

Passengers are loaded with a slider, similar to Cargo or Fuel in the pre-flight menu.

As the name may suggest, passengers can only be loaded onto passenger type aircraft. Different types will have different capacities for passengers, mostly depending on size.

Trivia

 * As they cannot be physically seen in game, they effectively share the same purpose as Cargo.
