:people_holding_hands: Community Q&A (No deep technical discussions)


:exclamation: Guideline for asking a Question

  1. Specify what you are trying to achieve
  2. Specify what environment / platform you are using
  3. Prepare a Link or Document to help understand if possible
  4. First, ask the question on the Slack or create a Github Issue!
  5. If you take over 5 minutes for the question, please continue in Slack or a Github Issue.

Q.1 :

Can you trigger the kill switch from QGC? (moving away from RC)
We think you should use the MAV_CMD_DO_FLIGHTTERMINATION mavlink message, and there are other params that help you roll back if needed before termination

:construction_worker_woman: Project Updates


P.1 :

Switching to control allocation by default, but we need to move the airframes and mixer files. This is the right time to start doing this
Plan:

P.2 :

Request for comments for a new failsafe state machine architecture:

Proof of concept for all the mechanisms we should need to replace the current failsafe handling. Can be simulated by building a local web application directly from the C++ code to test out scenarios easily.

P.3 :

Priority inheritance bug in NuttX.
The last remaining release blocker for PX4 1.13 was a priority inheritance bug in the real time OS that was found by brute force constantly disarming.
