Foreflight w&b setup

[arkvet]

I'm sure questions of this nature have been asked before but I just want make sure I’m doing this correctly.

I’ve set up my PA32 Saratoga in Foreflight for W&B but my graph looks different than the one in the POH. I don’t understand what causes “bulge” in the gross weight allowance in the POH. The foreword CG limitation is linear in Foreflight yet has a bend or bulge at ~83.5 / 3200.

I’m going to attach some pics that should help. As you can see my Foreflight graph is linear from 78 to 90.

I doubt this discrepancy will have much impact on my calculations as I’m pretty sure I’d have to put concrete blocks in my nose baggage compartment to ever get close to this area.

I just want to be sure I’m doing this correctly

Numbers for the 'bulge' are on the type certificate - attached if it's the correct one for your serial number.

Perfect. Thank you!
