That would be the correct way to use the program. However, it appears some are thinking they can just get rid of all the paper charts and use Foreflight ase their only source of charting. That's OK only with the windows based version of Jeppview/Flitedeck.
I've read the pertinent AC's and I don't find where it says you can't in lieu of paper, assuming we're all straight Pt. 91.
AC 120-76A: "Other part 91 operations do not require any specific authorization for EFB operations provided the EFB does not replace any system or equipment required by the
regulations."
AC 91-78: "Class 1 and Class 2 EFB can be used during all phases of flight
operations in lieu of paper reference material when the information displayed meets the
following criteria:
a. The EFB system does not replace any system or equipment (e.g. navigation,
communication, or surveillance system) that is required by 14 CFR part 91.
b. The EFB system on board the aircraft displays only precomposed or interactive
information which are functionally equivalent to the paper reference material which the
information is replacing or is substituted for.
c. The interactive or precomposed information being used for navigation or performance
planning is current, up-to-date, and valid, as verified by the pilot.
d. The operator complies with requirements of 14 CFR part 91, § 91.21 to ensure that the
use of the EFB does not interfere with equipment or systems required for flight."
Again, this is strictly Part 91. Any other, including fractionals, is out the window. You may find in the AC's lists of requirements that would exclude the iPad and then shortly after there'll be a note saying, in short, "doesn't apply to Part 91". Is it wise to have zero backup? No. Can you do it Part 91? Everything I see points to yes. Not trying to challenge you here but seriously, if you find something to the contrary, let us know. A LOT of people are starting to use the iPad. I think Foreflight's disclosure is a CYA.
