Garmin Pilot W&B

[Stewartb]

I'm trying to use the W&B in Garmin Pilot and now can't save my aircraft info because the app requires "longitudinal envelope points" and notes to enter them in clockwise order. I have no idea what it's asking for. Help???? Please????

Not sure, but probably it's missing something and wants you to put in all the "corners" of the W&B graph,

Bingo! You are correct and looking back it makes oerfect sense. It totally escaped me earlier. Thank you.
