Where is the "commercial flying" defined as it is used in the following regulation? I need a REGULATORY reference. Thanks guys.....

Section 135.267: Flight time limitations and rest requirements: Unscheduled one- and two-pilot crews.

b) Except as provided in paragraph (c) of this section, during any 24 consecutive hours the total flight time of the assigned flight when added to any other COMMERCIAL FLYING by that flight crewmember may not exceed --

(1) 8 hours for a flight crew consisting of one pilot; or
(2) 10 hours for a flight crew consisting of two pilots qualified under this part for the operation being conducted.
