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.
