* points disregarded because of the existence of more limiting points at

The table below shows the determination of the aft constrained limit for
the EMB-135LR model.
For Takeoff & Landing & In-flight limits the allowance used was:
• +150865.00 lb.in (aft flight allowance)
• + 71857.19 lb.in (aft seating allowance)
+222722.19 lb.in = total aft allowance
NOTE: The allowance at 25353 lb is zero because in this weight range
it is impossible to have passengers loaded, so the seating
allowance was disregarded and also the flight allowance.
