CARGO TRANSPORT

In the Microsoft Flight Simulator 2024 career mode, one of the challenges that a user can take is to fly cargo runs ranging from short local delivery flights in small aircraft, to long-haul global freight delivery in large airliners. If you wish your aircraft to be used on these activities you will need a preset that has been appropriately set up as part of the Modular SimObject, as explained below.

Cargo Constraints

When it comes to setting up aircraft for the available cargo activities, there are a few requirements that must be fulfilled by both planes and rotorcraft:

• The aircraft will need to have the navigation_graph_pilot.cfg (as explained here).
• The operating_status must be either "in_service" or "experimental".
• The aircraft cannot be flagged as premium.
• The aircraft ui_max_range must be greater than 1.

 

Following the constraints given here for planes will give the aircraft the CAR_Cabin type. Following the constraints given here for rotorcraft will give the aircraft the CHT_Cabin type. See here for more information:

• Note On Cabin Codes

• The plane cannot have skis or floats for landing gear.

 

 

Remote Cargo Operations (Planes)

For planes the following constraints will also be used:

• The aircraft will need to have the ApronWithBatteriesWithoutCovers.flt file (as explained below).
• The object_class must be "Airplane"
• The plane must be flagged as military.
• A copilot must be assigned to the plane (see here for information).
• The payload mass must be greater than 1kg (see Note On Payload Mass for more information).
• The fuselage volume must be less than 1m³ (see Note On Fuselage Volume for more information)
• The plane can have wheels or big wheels, for landing gear.
• The plane cannot have skis or floats for landing gear.

 

 

Cargo Transport (Rotorcraft)

For planes the following constraints will also be used:

• The aircraft will need to have the ApronWithoutCovers.flt file (as explained below).
• The object_class must be either "rotorcraft" or "tiltrotor".
• The rotorcraft cannot be flagged as military.
• The rotorcraft must have a copilot (see here for information).
• The payload mass must be greater than or equal to 35kg and less than or equal to 680kg (see Note On Payload Mass for more information).
• The fuselage volume must be greater than 1 (see Note On Fuselage Volume for more information)
• The rotorcraft can have either wheels or skids for landing gear.
• The rotorcraft cannot have floats for landing gear.

 

 

Note On Fuselage Volume

Some cargo activity specialisations will only accept aircraft which respect a volume constraint. This volume value is calculated in cubic meters (m³) in the following way:

$$FuselageVolume=\pi \times FuselageLength\times (\frac{FuselageDiameter}{2}{)}^2\times {0.3048}^3$$

Where:

• $FuselageLength$ is the fuselage_length in the flight_model.cfg.
• $FuselageDiameter$ is the fuselage_diameter in the flight_model.cfg.
• $0.3048$ is the value used to convert the ft values into a meter equivalent.

 

 

Cargo Setup (Planes)

Once the aircraft model has been prepared for cargo activities and the Modular SimObject has been created with a preset that uses the adapted model parts and respects the constraints, the next thing to do would be to add in the required navigation_graph.cfg files. For cargo missions this means that you will need an additional file - added using the Navigation Graph Editor - that must be named exactly as follows:

navigation_graph_cargo.cfg

 

You will also need various SimPropContainer XML files defining the visual contents of the cargo, as well as a loads.lbl file which is used to select the appropriate SimProp Container object to display. Since the setup of cargo is complex and is also shared between different aircraft modes (for example, passenger aircraft can have cargo to represent the passenger suitcases), the process is fully documented on the following page:

• Aircraft Loads

 

 

Cargo Setup (Rotorcraft)

The only cargo activity available for your helicopter is one using a cargo hook attachment under the helicopter to transport cargo from loading points around the globe to hard-to-reach destinations. As with the cargo activities for planes, it is important that the model is set up correctly and that the navigation graph and flight model files are correctly configured (as described in the Cargo Transport (Rotorcraft) section, above).

 

 

Helicopter Model

When modelling the helicopter, the artist should model the entire cargo hook assembly underneath the helicopter, and there should be a "helper" node in the glTF that is called Hook_Tip_Rope_ATTACH. This should be placed at the point on the cargo hook assembly where the rope would be deployed and should be present in at least the LOD0 and LOD1 glTFs.

 

 

FLT Files

When a user starts a cargo activity they will not be going through the usual Preflight checks, and so they will need to have a special apron FLT file instead of the usual Apron.flt. This file should be set up like a regular apron FLT file, however you should ensure that the following parameters and sections are setup correctly, depending on the aircraft:

 

For heavy / Super heavy / Remote Cargo Ops you will need to use the ApronWithBatteriesWithoutCovers.flt, setup as follows:

 

• Section [SimVars.0] must have the parameter SimOnGround set to true.
• All [Covers] needs to be set to false.
• Section [Controls.0] must have the parameter ParkingBrake set to 100.00 (if the aircraft has a parking brake).
• Engines must be turned off.
• The communication system must be turned on.

 

For helicopters you will need to use the ApronWithoutCovers.flt, setup as follows:

 

• Section [SimVars.0] must have the parameter SimOnGround set to true.
• All [Covers] needs to be set to false.
• Section [Controls.0] must have the parameter ParkingBrake set to 100.00 (if the aircraft has a parking brake).
• Aircraft electrics and engines must be turned off.
