HI
My Discus 2a manual says the ARM for Pilot & Parachute is ( -17.72 in.)
The A&P who did the WT & Balance 10 years ago used ( -15.20 in.) for the ARM.
Did he make a mistake? It's a big difference.
If you have a D2a can your check your WT & BAL for me.
If I could get a copy of your W&B that would be great.
Thanks

See if the manual specifies different arms for light and heavy pilots.
