UTC1100 - Remove legacy attribute: display="bitmask" by hamishwillee · Pull Request #383 · ArduPilot/mavlink · GitHub
- Remove legacy display= bitmask
- Inferred by the using the field type
- This would break dump_message_verbose
- We can infer display=bitmask for those things that have enumerations
- There are places upstream where flags are defined by a vendor
- We display as hex
- Could add custom_flag_1, custom_flag_2
UTC1120 - ArduPilot 4.6 issues list · Issue #28612 · ArduPilot/ardupilot · GitHub
- 4.6 issues list
- Beta4 has been merged onto the beta branch
- Copter, Rover and Tracker
- Tridge will tag Plane this-morning
- No new issues brought up for Plane that tridge is aware of
- Bill is putting a lot of effort into looking at the potential regression in oscillation
- Modelling behaviour is tough for this vehicle
- We may be able to say we can’t resolve the issue completely
- We did gain a sysid implementation for Plane out of it
- And a chirp system for ESCs which came back with a low frequency 2Hz cut-off for these ESCs!
- We may discover very low effective cut-offs on the motor/prop combinations
- Just need ESCs with feedback
- Somewhat asymmetric
- Braking vs accelerations, probably
- Racing quad was getting 10Hz symmetric
- Tridge will bring a PR to emulate this stuff in SITL
- … and the chirp lua script
- Maybe a custom-build-server thing would be good
- Bill did find some oscillations but of a different sort
- We’ve failed to find any convincing evidence there’s a regression
- Maybe Leonard’s “it is right on the edge” and a low sample size means we can put this issue aside
- Autotest run system ID on vehicle and compare the transfer function of the known solid representation of the vehicle
- Still a couple of issues that should be cleared up
- Reboot loop after enabling scripting
- Holybro M10 user is still having issues
- We want a log
- Nessie has an M10 on it
- Thomas reports he has several
- Bzgnzss
- Bidir is working on this GPS
- Throttle issue on Plane George looked at and stated it was a desired change
- SPI transfer overhead overwhelming
- Everything marked for backporting has been merged
- This is probably the last beta

- non-GPS avoidance
- It was never good
UTC1152 - Plane: Fixed formulas for load factor and roll, also corrected _TASmin in AP_TECS accordingly by IamPete1 · Pull Request #29101 · ArduPilot/ardupilot · GitHub
- Fixed formulas for load factor and roll
- Non-functional change
- Just corrects to use the standard definitions
- Merged!
UTC1153 - AP_TECS: Fix flare height demand when using a rangefinder by rubenp02 · Pull Request #29230 · ArduPilot/ardupilot · GitHub
- Fix flare height demand when using a rangefinder
- Needs logs and/or autotest
- Probably right
UTC1158 - AP_Proximity: Hexsoon Radar support by rmackay9 · Pull Request #29235 · ArduPilot/ardupilot · GitHub
- Hexsoon / nanoradar
- “Radarcan” protocol name
- Can be merged once duplication has been fixed
UTC0001 - AP_Frsky_D: Enhanced, add power, time, temperature, acceleration etc by Paku- · Pull Request #29278 · ArduPilot/ardupilot · GitHub
- Frsky d telemetry
- Let’s have D off by default then we can add this in
UTC0003 - ArduPlane:add AUTOLAND AUX Function by Hwurzburg · Pull Request #29279 · ArduPilot/ardupilot · GitHub
- Several people asked for this
- Option to enter autoland via an aux function
- Can be merged once problems fixed
UTC0007 - AP_GPS: fixed the check for disabling CONFIG_RATE_SOL config by tridge · Pull Request #29320 · ArduPilot/ardupilot · GitHub
- Potential fix for M9 GPS problem
- SOL is absolutely ancient
- We started to use PVT message instead
- PR fixes testing of config-rate-sol
UTC0011 - Add Autoland batt fs action by Hwurzburg · Pull Request #29281 · ArduPilot/ardupilot · GitHub
- Batt fs action for autoland
- No-climb enforced
- Discussion around climbing
- Above-home vs terrain
- Tridge doesn’t like the current behaviour
- 120m above ground when you enter
- Then you hit failsafe and break your legal limit
- Also climbing with battery failsafes…. Not usually good
- We will anyway
- in-RTL and in-landing sequence concerns
- Maybe we should trigger autoland after doing an RTL where we entered the RTL because of a battery failsafe?
- Make it configurable?
UTC0019 - Add Autoland fence action by Hwurzburg · Pull Request #29280 · ArduPilot/ardupilot · GitHub
- Autoland fence action
- Did we want to modify the climb?
- If you breach the max-alt fence you probably don’t want to climb!
- Re-entering autoland should definitely not run the entry code again
- There are checks for this

- Stop MaxsonarI2CXL driver using ownptr
- Merged!
UTC0034 - Mark many functions for storage in external flash by peterbarker · Pull Request #29290 · ArduPilot/ardupilot · GitHub

- Only called at board startup
- Marking everything as in-external and then coming back and marking stuff as not?
- Thomas says that approach has caused pain on ESP32
- Can be merged after comments have been added

UTC0051 - AP_NavEKF3: elevate compass change statustext alert by rishabsingh3003 · Pull Request #29299 · ArduPilot/ardupilot · GitHub
- Elevant compass change statustext alert
- CRITICAL is too much
- Switching compass is pretty common
- Really need to work out whether switching to the other is a good idea or not
- Innovation heck for compass switch
- Calculate what innovation would have been
- Could be notice?
- Need to know what it looks like in MissionPlanner
UTC0101 - AP_NavEKF3: revert to primary compass on ground by rishabsingh3003 · Pull Request #29300 · ArduPilot/ardupilot · GitHub
- Switch back to original compass when on ground
- This should be done in the same way we do lanes
- Ie. based on armed rather than onGround heuristic
- Need to worry about the magically updating offsets
- We do like the thing of going back to default state

- Merged!
UTC0133 - AP_Compass: throw away all samples which aren't acceptable in thinning by peterbarker · Pull Request #29312 · ArduPilot/ardupilot · GitHub
- Discard all bad samples in compass calibrator rather than just accepting bad ones off the end of the list
