Having played around today with 3.9 (iOS), I do miss the Flight Details tab for 1-click access.

I use it quite a lot not just for W&B but also to set aircraft, set takeoff time, view flight time (on iPhone, though this is now on main map like on iPad so not an issue), and set fuel. I guess this is more important when planning than in flight.

I agree. I think that placing such fundamental route parameters such as which aircraft profile you will use, date/time of flight, weight and balance and fuel calcs two levels down is a backward step.

Worse are the inconsistencies in workflow. Changing some details leaves you in the Flight Details pop up, whereas entering fuel takes you back to the ‘Route’ pop up and completing W&B kicks you out completely!

Also, you now have to go to the Plog to see the flight duration and ETA, whereas previously they were directly visible under the entered date/time.
