Movements contain some randomisation.

Non Controllable Randomisation

For each ground support vehicle arriving at a ramp, it is not possible to decide where the vehicle is coming from. It will always come from a X-Plane so-called parking position.

It is not possible to decide where the vehicle will go after service. It will always go to a X-Plane so-called destination position.

Parkings and destinations are special points on the X-Plane airport. X-Plane uses these positions to randomly create ground movements.

Parkings and destinations have an X-Plane type that determine which vehicle or type of vehicle can access it, like baggage_loader, baggage_train, crew_car, crew_ferrari, crew_limo, pushback, fuel_liners, fuel_jets, fuel_props, food, gpu. These X-Plane specific types are converted to LATA service types so that these parking and destination positions are typed according to X-Plane use if a correspondance can be made.

X-Plane Service Vehicle
baggage_loader Baggage baggage-belt
baggage_train Baggage baggage-medium
crew_car Crew coach-car
crew_ferrari Crew coach-car
crew_limo Crew coach-bus
pushback Aircraft pushback
fuel_liners Fuel hydrant
fuel_jets Fuel tanker-large
fuel_props Fuel tanker-medium
food Catering catering
gpu Aircraft gpu

LATA is not specific to a precise vehicle type, but rather to all vehicles for a type of service. An X-Plane parking or destination that accepts fuel_liners will accept all fuel service vehicles in LATA.

If no specific parking or destination can be found, a random one is selected.

Tip and Tricks for Realistic Randomisation

It is not possible to use randomisation without a few constrains. For example, if the parking is randomly selected, one day or another, LATA will select the same parking twice and aircrafts and ground support vehicle will collide. The trick is to exclude random values that have already been used from new generated ones.
