Must be able to update online. No rebooting or mucking with SD cards.

figure out how to

• physically connect it to raspberry Pi
• read data from it

Everyone seems to be talking about Kalman filters.

• altitude/airspeed adjustment
• how does this relate to high bank angles?

Current feedback:

• Build
• Kill old process
• Optionally reset X-Plane (home runway, at-altitude, other scenario)
• Unlock the brake if on runway, extend flaps, deal with gear
• Start new process

Meanwhile X-Plane chews my CPU.

Need to get it down to one command to unpause X-Plane process, launch control process, reset scenario, etc.

Likely to be used in a tight development feedback loop, needs to be quick and easy. Probably a separate tooling daemon (not a part of the main fcs binary) for kicking xplane into doing various common things.

or something? seems like flying to waypoints and flying in arbitrary circles is pretty much the same problem. pick a power setting and go for it.

also fly the tail. no lateral g's! perfect turns.

SparkFun 9-DoF stick looks cool. $100-ish.

Would be great to have a glass cockpit running on the laptop. Especially to aid recovery.

other ideas

• way point sequences/linger
• save GPS location to return home/mission destination/etc
• maintain pattern w.r.t. ground despite wind
   - transitioning between trajectories/modes

Could do all manner of cool stuff using crazy functions and Frenet-Serret coordinates.

Correct upsets in pitch, roll, yaw due to turbulence/wind. PID loop?

create enum/map for channel names/numbers

Essentially an interface implemented by both the xplane backend and the IMU backend.

Make or re-use a course editor. Also includes tweaks to core to enable taking new waypoint list as input in real-time.
