Airspeed VTOL mode incorrectly displayed

In Flight Review, it shows that the VTOL has transitioned to fixed-wing when True Airspeed is ~14 m/s. But in PlotJuggler, it shows that VTOL has transitioned to fixed-wing when True Airspeed is ~11 m/s.

I'm leaning towards PlotJuggler being correct because we set the transition airspeed to 10 m/s. PlotJuggler confirms this happens if you look at the calibrated airspeed.

Why does the Flight Review graph look so different?

Very keen observation. Flight Review uses vehicle_status/in_transition_mode for the VTOL state, which happens to change a bit later:

There's 2 options for more accuracy:

• let PX4 publish vehicle_status on vtol transition change immediately
• change Flight Review to use vtol_vehicle_state (it currently does not use and thus depend on that topic)
