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.

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

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.

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"

Nope, the operator's handbook describes the flight envelope.

But you just told us the flight envelope is described by the airplane's ability
to perform a maneuver or enter a flight regime using a "normal" control
configuration! Which is it -- defined by a control mode or defined by an
operator's handbook (I will assume that includes a "Dash-1" for USAF airplanes
and NATOPS for USN airplanes and FAA approved Flight Handbook [FHB} for
Transport category aircraft)?

If the operator's handbook, how is the "flight envelope" described? In the
General Limitations and Specifications" section or "Maximum Airspeed Limits
Chart" in the Limitations section of an FHB? Something else? Something more?
