CONSTRAINED CENTER OF GRAVITY LIMITS
In order to determine the constrained CG envelope, the allowances
must be added to the certified CG envelope.
The table below shows the determination of the forward constrained
limit for the EMB-135LR model.
For Takeoff & Landing & In-flight limits the allowance used was:
• -10155.15 lb.in (landing gear)
• -4017.00 lb.in (forward flight allowance)
• -69630.06 lb.in (forward seating allowance)
-83802.21 lb.in = total fwd allowance
NOTE: The allowance at 25353 lb is -10155.15 lb.in, because in this
range of weight it is impossible to have passengers loaded, so
the seating allowance was disregarded and also the flight
allowance.
For Takeoff & Landing limits the allowance used was:
• -69630.06 lb.in (forward seating allowance)
