D.1 : Fixed Wing Precision Landing - Ryan & Andrew

By having a GPS and a Barometer at the landing site, the landing coordinate can be pin-pointed. Currently the ‘Terrain Estimator’ is very unpredictable. Auto Landing is broken as well!

D.2 : Flash Overflow on Build Tests in the PR

  • Targets like CUAV* can include a lot of code along with it, so it often overflows - Daniel

D.3 : X500 V2, with v5x hardware flight testing - Farhang

  • Canceling a Mission in Flight - Ryan
    • A user on discuss wants the ability to take his quad out of mission mode from his RC
      Remote then when goes back into mission have the mission start over. I never really thought about it but this is actually a parameter that should be added so when you switch out of mission, waypoint count is reset then back to mission mode and it starts over.
      From Discuss but actually an interesting idea for a parameter.
