Average weight of an ACM in the Aft Jumpseat?

• A. 225 Pounds
• B. 254 Pounds
• C. 260 Pounds
• D. 235 Pounds

Answer: (A)

In weight and balance, each person and occupant position on the aircraft is assigned a standard weight to simplify planning while still keeping the CG accurate. For the CRJ-550, the Aircraft Cabin Manager (ACM) occupying the Aft Jumpseat is assigned a standard weight of 225 pounds. This value reflects a typical crew member plus any essential gear and reflects where that person sits, which is toward the rear of the aircraft and thus influences the center of gravity accordingly. Using this published figure helps ensure CG calculations stay within limits across routine loads without needing to weigh every crew member for every flight. Other weights would either overestimate or underestimate the ACM’s contribution to the load, potentially skewing the balance. If actual weight deviates significantly from this standard, managers can adjust with actuals, but 225 pounds is the standard figure used for planning.
