Kent,
That is exactly the quantitative explanation I need. I was thinking about approach descents. I'm down right now replacing a fuel pump. BTW I don't use ForeFlight, I use Avare. It is less capable, but doesn't require a yearly subscription or Apple hardware.
Truth be known, I'm having a hard time finding a use for a tablet. Most of what people use a tablet for, is in my Dynon Skyview. I flight plan with my laptop or workstation in my office at the hangar. It frequently seems in the way, even on a knee board. I don't have a right seat in my Long eze. Right now, I'm seeing it as a battery powered emergency backup.
Thanks for the help.
