Ground/Takeoff and 

Initial Segment of 
Climb.

Record results of takeoff flight 

path (running takeoff and take-
off from a hover). The criteria 
apply only to those segments 
at airspeeds above effective 
translational lift. Results must 
be recorded from the initiation 
of the takeoff to at least 200 ft 
(61 m) AGL.
