Ground/Takeoff and Initial
Segment of Climb.
Record results of takeoff
flight path as appropriate to
helicopter model simulated
(running takeoff for Level
B, takeoff from a hover for
Level C and D). For Level
B, the criteria apply only to
those segments at air-
speeds above effective
translational lift. Results
must be recorded from the
initiation of the takeoff to at
least 200 ft (61m) AGL.

Because several kinds of
takeoff procedures can be
performed, the specific
type of takeoff profile
should be recorded to en-
sure the proper takeoff pro-
file comparison test is
used.
