Pre-takeoff checklist
Here's the ramp video:

Blackhawk flies across the runway at 0:05 into the video and the Cirrus enters the frame approximately 0:26 into it. The disruption occurs as the Cirrus nears the area where the heli crossed. Not very familiar with the lingering effects of a helicopter's downwash but I would have figured that twenty seconds would be sufficient to dissipate that energy. Apparently not. Thankfully the pilot was not killed.
