Without getting too technical.
An aircraft is "flying" regardless of whether it is climbing, decending
or "flying" level.
By using the throttle and the attitude of the nose of the aircraft the
pilot controls the relative airflow over the wing and thus determines
the mode of flight he wants.
Climbing - Lift is Greater than weight
Level - Lift = weight
Descending (including landing) - Lift if less than weight
All the above are controlled "flying"
The stall is uncontrolled "flying" and the only time this should happen
whilst "flying" is in stall recovery practice, aerobatics and sometimes
a second prior to touchdown.
