If your F-105 is capable of doing something inside its flight envelope, it
is normal operation.

An example of an abnormal operation is the cobra manouver, as the flight
controls are altered from normal operation.

How are the flight controls "altered from normal operation"?

The operator must disable the control system augmentation in order to do a
cobra manouver.

What part of the cobra maneuver is outside the airplane's flight envelope?

The airplane will not do a cobra manouver with the control's augmentation
on.

How do you define "flight envelope" in context?

I define it the same way as you would an F-18 in "cable actuated system"
mode.

I don't define "flight envelope" in any context with reference to any F-18
system mode...

So, what was the "normal operation" mode of the F-106 flight controls?

By your definition/description of "flight envelope," any maneuver or regime an
airplane can enter with any control input, using "normal" control authority is a
"normal operation."

Using that definition, any maneuvers prohibited by the Operator's Handbook or
other limitations would be considered "normal" if they were achievable using the
"normal" flight control mode. So, do you consider as "normal operation" any
departure from controlled flight, spin (even if entered inadvertently, in an
aircraft in which intentional spins are prohibited), or extended inverted flight
(even if it causes oil or fuel starvation to the engine)? Many airplanes can
enter these flight regimes with flight controls in "normal" configurations, but
few pilots would consider them "normal operations" in most airplanes.
