  • People are uncomfortable with this
  • Don’t want two ways to two things
  • We are very skeptical of the DroneCAN thing

    • E.g. ALT_HOLD

UTC1148 - terrain data issue

  • Should we send out a user alert?
  • Git commit reference for the fix doesn’t make a lot of sense in this case
  • Requires further investigation
  • Randy doesn’t think it’s going to work
    • Issue is not related to an ArduPilot flight code issue
    • Doesn’t make sense to tie to a particular version of ArduPilot
    • Maybe the fix is the one that’s referenced
  • Do we need a 4.6.4 with the prearm failure in it?
  • We’ll need some sort of dry run
  • Let’s talk about it again next week
  • Would we have to provide patches for 4.0, 4.1, 4.2, 4.3, 4.4, 4.5 too?
  • Maybe ask the partners what they think
