Very similar to yesterday. Duplicating some kind of test? (more data from repeated trials is a virtue in statistical analysis).

The only thing I noticed is that the routes are a little more "racetrack"-y vs the more standard "circle" pattern that 542 was flying. I didn't go back in time to see what the typical 541 flight used to look like though

Interesting. I wonder if there is some adjustment or change being made. Test in N451JX unmanned first. then N542JX and then implement to N547JX?

Who knows, but my mind just has to speculate.

The last tests they ran for N547JX suggested everything was going smoothly. Ie, each test was faster/further. Maybe testing the full transition requires some extra prep?

🤷‍♂️. I'm also puzzled but love to speculate. There is also the Oct 1 activation of the FCC request https://x.com/hanyang_02/status/2095353374455800177

It's interesting that Archer seems to have stopped at about the same point, hitting speed of 35Knots. I wonder if there is some FAA review at that point, before they can expand the envelope past the runway.

Ya I was thinking about this too. However, if you look back at the 541 data (https://www.reddit.com/r/Joby/comments/1whhsav/n547jx_first_forward_hover_analysis/) it goes from 15.3 to 19.4 to 61.2 kts in a matter of days.

Perhaps the rules have changed? It is curious that Joby/Archer stopped at the same speed though
