UTC2300 - https://github.com/ArduPilot/ardupilot/pull/16842

  • Fix for covariance matrix stability issues
  • CI failures unrelated
  • Merged
  • Replay worked for us!
  • There’s some refactoring which could be done in here

UTC2307 - https://github.com/ArduPilot/ardupilot/pull/15546

  • Not ready for merge yet

UTC2309 - https://github.com/ArduPilot/ardupilot/pull/13853

  • Is galileo even testable in Australia?
  • There are messages we could enable to know which satellites are being used
  • Bit confusing on the F9 exclusion stuff
    • What about M7 and M6?
  • Should only break things if you’ve changes the parameter
  • Need MdB to look at this

UTC2320 - https://github.com/ArduPilot/ardupilot/pull/16966

  • cell voltage and resting voltage id in OSD
  • Would be nice to have a reliable cell count for failsafe purposes, but guessing isn’t great

UTC2327 - https://github.com/ArduPilot/ardupilot/pull/16964

  • Retry SP06 detection
  • This is fine once reworked

UTC2328 - https://github.com/ArduPilot/ardupilot/pull/16948

  • Control pitch up in VTOL transition with user targets
  • Linear curve for pitch like forward transition
  • Current pitches up at your max forward pitch rate
  • Don’t return AP_Int
  • Overshoot issues?
  • PH will test
  • Need to get that nose up while you have airspeed, does this still allow it?
  • Sideways back-transition using differential thrust is a thing…
    • Dual-motor tailsitters which have lots of power

UTC2346 - https://github.com/ArduPilot/ardupilot/pull/16946

  • Reset the counter so we avoid the 10 second gap in the log
  • We really do need to audit for millis32 wrap
  • 64-bit timestamps?

UTC2350 - https://github.com/ArduPilot/ardupilot/pull/16945

  • Will be accepted once it is fixed up
  • Default will need to be on

UTC2354 - https://github.com/ArduPilot/ardupilot/pull/16938

  • Allow code currently running in a thread to run on main thread
  • Needs many more comments
  • Smaller impact?
    • Semaphore in AP_Logger where AP_Logger takes semaphore before doing disk write
  • SIM_OPTIONS to choose async vs normal threading

UTC0026 - https://github.com/ArduPilot/ardupilot/pull/16937/files

  • Leonard pinged on trivial comment fix

UTC0027 - https://github.com/ArduPilot/ardupilot/pull/16927

  • Separate descent rate like Copters while in Q modes
  • Without rename is fine
    • Randy thinks it should be pilot-speed-up and pilot-speed-down
  • Consistency with other vehicles is a fine idea
    • So if one vehicle does it one way the others should follow where possible
  • Can be merged on CI pass

UTC0041 - https://github.com/ArduPilot/ardupilot/pull/16904

  • Two additional pointers that are only used in the narrow context of tailsitter input?
    • Confusing if the user tries to change parameters?
  • Fixes a bug…
    • Simpler bugfix….
    • 16841 merged in preference
