New subject. Where can I get the positive and negative G limits
of commercial birds, 747, 757, 767, etc? I want operational
limits not ultimate. Have looked on Internet and not found so
far.


Section 25.337: Limit maneuvering load factors.
(a) Except where limited by maximum (static) lift coefficients,
the airplane is assumed to be subjected to symmetrical maneuvers
resulting in the limit maneuvering load factors prescribed in this
section. Pitching velocities appropriate to the corresponding pull-
up and steady turn maneuvers must be taken into account.

(b) The positive limit maneuvering load factor n for any speed up
to Vn may not be less than 2.1+24,000/ (W +10,000) except that n
may not be less than 2.5 and need not be greater than 3.8 -- where
W is the design maximum takeoff weight.

(c) The negative limit maneuvering load factor --

(1) May not be less than -1.0 at speeds up to VC; and

(2) Must vary linearly with speed from the value at VC to zero at
VD.

(d) Maneuvering load factors lower than those specified in this
section may be used if the airplane has design features that make
it impossible to exceed these values in flight.
