Chinook CG Range
SAS, maybe the BV marketing troops thought it was 144 inches.
People evaluating the CH-47 vs the CH-53 ( thinking UK, Israel and Germany ) always got a surprise when they found out that the CG ranges were almost identical. I know the 53A/D went from 328" to 352" and I just looked up the CH-47D on an Army wt and balance presentation and at 42,000 lbs, their CG range went from 316" to 338". Pretty close.
Thanks,
