AFT FLIGHT ALLOWANCES
A reasonable aft flight allowance is to consider the movement of the
forward flight attendant and a trolley to the aftermost row combined
with the movement of a mid cabin passenger to the lavatory.
Example:
EMB-135ER
Aft Allowance Weight
(lb)
from Arm

Moment
(lb.in)
Mid cabin pax to lavatory 170 * 429.53 672.05 +41228
Fwd attendant to aft
cabin
170 188.98 609.06 +71414
Trolley to aft cabin 88 190.55 624.90 +38223
Total = +150865
* Passenger is assumed to have no hand baggage when moving to
lavatory.
So, the aft flight allowance will be +109637 lb.in, adopting the most
restrictive situation.
