Examples
• Quadcopter Project — New example that shows how to use Simulink Projects and
Aerospace Blockset™ blocks to model a quadcopter. It uses the Flight Simulation
Example Simulink project template to manage the model and source files. For more information on this template, see Simulink Projects Template for Flight Simulation
Applications.
• NASA HL-20 with FlightGear Interface — Existing example updated with a Run
FlightGear block to help you get started using FlightGear for the example.
Receive net_ctrl Packet from FlightGear data storage change
The Receive net_ctrl Packet from FlightGear block no longer stores the UdpRecvPkt signal at simulation when you select the Data Import/Export > States or Final states checkbox. In previous releases, the block stored this signal.
Equations of motion 3DOF and 6DOF acceleration values
The equations of motion 3DOF and 6DOF blocks now include the gravity and rotating frame terms when calculating the accelerations of the body with respect to the inertial frame. As a result, you may notice different acceleration values.
Compatibility Considerations
If your model has 3DoF and 6DoF blocks from library versions prior to 3.13 (R2014a), you can use the Aerospace Blockset check in the Simulink Upgrade Advisor to identify the blocks in your model to replace. For more information, see Check model for legacy 3DoF or 6DoF blocks.

Conversion of Error and Warning Message Identifiers
For R2011b, error and warning message identifiers have changed in Aerospace Blockset.
Compatibility Considerations
If you have scripts or functions that use message identifiers that changed, you must update the code to use the new identifiers. Typically, message identifiers are used to turn off specific warning messages.
For example, the aeroblk:sltranslate identifier has changed to aeroblks:sltranslate:invalidVersion. If your code checks for aeroblk:sltranslate, you must update it to check for aeroblks:sltranslate:invalidVersion
instead.
To determine the identifier for a warning, run the following command just after you see the warning:
[MSG,MSGID] = lastwarn;
This command saves the message identifier to the variable MSGID.
Note: Warning messages indicate a potential issue with your code. While you can turn off a warning, a suggested alternative is to change your code so it runs warning-free.
Efficient C Code Generation
With the code reuse functionality from Simulink Coder™, the Aerospace Blockset software now has efficient C code generation for all blocks. In previous releases, you could not reuse generated code.

Use the new SimState feature to save the complete simulation state. Unlike the final states stored in earlier versions of Simulink, the SimState contains the complete simulation state of the model (including block states that are logged). You can then restore the state at a later time and continue simulation from the exact instant at which you stopped the simulation. See Saving and Restoring the Simulation State as the
SimState in the Simulink User's Guide.

The Pilot Joystick All block provides a joystick interface on Windows ® platforms. This block is the same as Pilot Joystick, but its Output configuration parameter is set by default to AllOutputs. It outputs six analog channels, buttons, and point of view indicators.
WGS84 Gravity Model Block Modified
The first input of the WGS84 Gravity Model block is now a three-signal vector that contains the position in geodetic latitude, longitude, and altitude. The second optional input is now a scalar that contains the manually-specified Julian centuries. The WGS84

Interpolate Matrix Blocks Modified
The Interpolate Matrix(x), Interpolate Matrix(x,y), and Interpolate Matrix(x,y,z) blocks have been modified to accept the new Simulink Prelookup block output. The

Aerodynamic Forces and Moments Block Extended
The Aerodynamic Forces and Moments block has been extended to allow calculations in the stability and wind axes, in addition to the body axes.
To preserve backward compatibility, the default state of the block assumes a body-body transformation and hides the body velocity input port. If you change this default to stability or wind axes, the body velocity port appears.

Flight Simulator Interface
Aerospace Blockset Software Version 2.0 supports an interface to the third-party
FlightGear Flight Simulator, an open source flight simulator software package. You can obtain the FlightGear Flight Simulator from www.flightgear.org.
The simulator interface included with the Aerospace Blockset software is a unidirectional transmission from the Simulink software to FlightGear using FlightGear's published net_fdm
binary data exchange specification transmitted via UDP network packets to a running instance of FlightGear.
The Aerospace Blockset product currently supports the standard binary distributions of
FlightGear versions 0.9.3 and 0.9.8a on all platforms.
Note: There is a known problem with FlightGear running on Macintosh, where Weight on Wheels (wow) is 4 bytes, as opposed to other platforms where it is 1 byte. As a result, the Aerospace Blockset product might experience trouble communicating with
FlightGear if you are running FlightGear on Macintosh, and if you are using any of the following parameters:
• wow
• gear_pos
• gear_steer
• gear_compression
• agl
• cur_time
• warp
• visibility
For more information on the available parameters, see the reference page for the Pack net_fdm Packet for FlightGear block.
