Data Source/Sink blocks

  • Source blocks allow to import into the program any variable available in the system. Additionally the Const Real/Vector allows to create a constant variable or vector.
  • Sink blocks allow overwriting the following system variables:
    • User Variables
    • Desired variables (variables whose name starts with 'Desired')
Source/Sink blocks

Warning

  • Desired variables are naturally written by Guidances algorithms. If an active Guidance is writting a certain Desired variable, writting it with a Sink block should be avoided.
  • Using Sink blocks to overwrite System Variables usually results in the change not taking effect, but in some cases could end up causing Autopilot 1x to malfunction.
  • Avoid using Sink blocks to write any variable that does not belong to one of the groups listed above.
