Load Management in VDS

vAMSYS provides tools to determine load amounts for aircraft through Load Factors and Containers.

Load Factor Profiles

Load Factor Profiles use a mathematical formula to determine generated Passenger, Freight, Cargo, and Cargo Volume amounts when pilots dispatch a flight. You can edit all parameters of the formula:

$mean = $min + ($max - $min) * $bias;
$deviation = ($max - $min) * $deviation;
$rand1 = (float) mt_rand() / (float) getrandmax();
$rand2 = (float) mt_rand() / (float) getrandmax();
$gaussNum = sqrt(-2 * log($rand1)) * cos(2 * M_PI * $rand2);
$gaussNum = $mean + $deviation * $gaussNum;
$loadFactor = min(max($gaussNum, $min), $max);

Creating and Editing Load Factor Profiles

• Type: Choose from Passenger (People), Passenger (Hold Luggage), Cargo (Weight), or Cargo (Volume).
• Name: A friendly name for the profile to recognize it when assigning to routes or aircraft.
• Min: Minimum load factor in %.
• Max: Maximum load factor in %.
• Bias: Skewness of the generated numbers towards minimum or maximum, with 0.5 being even.
• Deviation: Degree of dispersion in the distribution of generated numbers, with a higher value indicating a wider spread.
• Set as Default Profile: Makes it default for routes with no profile selected.

Load Factor Calculator

A Load Factor Calculator is available to test variables and see potential outcomes.

Default Load Factor Profile

If no load factor profiles are created, vAMSYS uses the following default values:

• Min: 80%
• Max: 100%
• Bias: 0.9
• Deviation: 0.2

Containers

Containers can be loaded onto aircraft whose fleet supports them.

Creating / Editing Containers

• Name: Friendly name shown in container assignment and loading pages in VDS and Phoenix.
• Type: Container type, such as Pallet or LD-4 container, with auto-completion suggestions based on previous entries.
• Unit Size: Space taken by the container in an aircraft, defined in Container Units.
• Weight: Weight of the loaded container in kilograms.
• Notes: Any notes visible to pilots.
• Incompatible Containers: Containers that cannot be loaded simultaneously with this container.
