Drones and O&M, Jennifer Perry, SWOMA 2018 4Slide 7, Active Track Options available on Spark, Mavic, and Phantom
Figure 7, An infographic with three cells or sections. The first is labeled Trace and shows the drone traveling
over and just a bit ahead of a stick figure. The second is labeled Spotlight and shows the drone circle over
head of the stick figure. The third is labeled Profile and show the drone to above and to the side of the stick
figure, moving parallel to the stick figure’s movements.
Trace: The aircraft tracks the subject at a constant distance.
Spotlight: The aircraft will not trace a subject automatically, but it keeps the camera
pointing at the subject during flight.
Profile: The aircraft tracks the subject at constant angle and distance from the side.
*Active Track can also lock in on stationary objects

• Spark loses obstacle avoidance in profile mode of Active Track
Gesture Control
• Control the drone with just your hands.
• Can be used for video or pics

Slide 11, Eyes on the Client
Recorded Video
• Tello: No internal Memory and no SD card slot
• Spark: No internal Memory – use UHS-1 Micro SD cards up to 64 gb
• Air: 8gb internal memory –use class 10 micro SD cards up to 128 gb
• Pro: No internal memory - use UHS-1 Micro SD cards up to 64 gb
Live Steaming
• Tello: video to your smartphone and share to social media (uses phone memory)
• Range and strength can be extended to 400m with a portable powerbank and an
aftermarket USB range extender
• A game like controller can be purchased for easier controllability
Drones and O&M, Jennifer Perry, SWOMA 2018 7Slide 12, Live Streaming, Continued
Spark
• Live streaming only works when using a phone as a controller, not an RC
• iPhones work better
• Uses phone data L
• Easy to stream to YouTube or Facebook… from upper right corner of screen,
select Live Broadcast Platform
• May be necessary to set up YouTube for Live Streaming in advance
Mavic Air and Pro

Slide 13, Confidentiality concerns
• Livestream to Facebook means that all your friends can see it
• Livestream to YouTube requires a private channel that you allow other parents to
access.
• If you are saving the videos to external memory cards, then video can be shared
confidentially.
• Videos stored to internal memory or SD cards can be downloaded to computers.
• Use permission slips/signatures, etc.
Slide 14, Restrictions/Cautions
• Drones cannot fly over government buildings, national parks, or within 5 miles of
an airport. May get permissions form airports.
• Cannot fly over highways/traffic, sports arenas, or at night
• Drones cannot fly at all within 15 miles of Reagan National Airport or in DC. This
is called the Flight Restricted Zone (FRZ).
• Flying drones in many major cities may also now be illegal (traffic, privacy,
government buildings) but some areas of cities may still be ok. Get
permissions/find out if you are unsure to avoid fines.
• Do not attempt to record emergency responses (fire, police, etc)
• Keep drone under 400 feet
• Keep drone visible to you
• Register with FAA ($5.00) https://faadronezone.faa.gov
• Fly sober
Slide 15, Return to Home function
• May automatically return on low battery or signal loss
• May land automatically on low battery or signal loss
• May hover on signal loss – set preferences on DJI Go 4 App
• When returning, it will ascend to specified height first, then fly straight back, so
set the height taller than surrounding features.
Drones and O&M, Jennifer Perry, SWOMA 2018 8• When flying back, if signal is regained, you can cancel the action.
• You can call the drone back anytime by pressing a button on the controller
• You can have drone go to start point OR to where you now are
• Note: drones will just automatically land or hover if it’s 3-20m away
• Note: Spark @>100m away on RTH will disable obstacle detection
