DJI Agras T100/T70 Series/T25P: Seguridad de Vuelo, VLOS, Battery Warnings y Power Lines
DJI Agras T100/T70 Series/T25P: Seguridad de Vuelo — VLOS, Battery Warnings, Power Lines y Shutdown
El Flight Safety Notice del DJI AGRAS T100/T70 Series/T25P Disclaimer and Safety Guidelines v1.0 va más allá del preflight. Explica qué debe vigilar el operator mientras el aircraft ya está en el aire, qué sistemas no deben tratarse como infalibles, cómo responder a battery warnings, qué hacer ante high-voltage power lines y cuál es el shutdown order correcto después de landing.
Resumen: mantenga el aircraft dentro de VLOS, no dependa completamente de app/safety systems/obstacle sensing, mantenga más de 6 m de rotating motors/propellers, regrese promptly ante battery warnings, espere auto landing en critical battery, nunca toque un aircraft que haya colisionado con high-voltage power lines, no exceda la payload recommendation de DJI Agras y, después de landing, detenga motors → power off aircraft → power off remote controller.
1. Keep the aircraft within VLOS
DJI instructs operators to keep the aircraft within visual line of sight and to ensure there are no unauthorized people in the operating area.
2. VLOS is active monitoring, not just visibility
Seeing the aircraft is not enough if the operator stops observing the environment. The safety guideline expects continuous awareness.
3. Do not fully rely on the safety system
DJI explicitly warns against complete reliance on safety systems, app information or other automated functions.
4. Obstacle sensing can be limited by the environment
Certain conditions can prevent the aircraft from sensing or bypassing obstacles. Maintain visual awareness and active control.
5. App data is a tool, not a substitute for judgment
Use DJI Agras to support the flight, but do not treat screen information as the only source of situational awareness.
6. Keep unauthorized people out of the operating area
The flight area should remain controlled enough that people do not unexpectedly enter the path of the aircraft.
7. Rotating motors and propellers: >6 m
Stay more than 6 m from rotating motors and propellers.
8. Handle propulsion only with aircraft powered off
Propeller/motor handling should occur with the aircraft powered off.
9. Battery warning: return promptly
When battery warnings appear, bring the aircraft back toward the Home Point promptly.
10. Do not stretch the warning into extra mission time
A warning is not a productivity target. Use the remaining energy margin to recover safely.
11. Critical battery triggers auto landing
The safety guideline states that at critical battery level, auto landing is triggered.
12. Horizontal control remains available
During critical-battery auto landing, the operator can control the aircraft horizontally with the remote controller.
13. Guide the aircraft to a safe place
Use horizontal control to move away from hazards and land as soon as possible.
14. Battery warnings should be logged
For recurring warnings, record aircraft ID, battery ID, level, environment and task context before concluding that hardware replacement is needed.
15. Power lines require route planning
If high-voltage lines are in the task area, plan the route to maintain safe separation before takeoff.
16. High-voltage collision: do not touch the aircraft
DJI warns not to touch an aircraft that has collided with high-voltage power lines because of electric-shock risk.
17. Treat the area as electrically hazardous
Do not approach based on the assumption that propulsion has stopped or that the aircraft is no longer energized by the line.
18. Use the dedicated power-line checklist
The source directs operators to DJI SmartFarm for the checklist related to power-line operations.
19. Night operation and spotlight
Do not look directly at the aircraft spotlight during night operation because of eye-injury risk.
20. This source is not a complete night-flight regulatory framework
The warning is operational. Country-specific night-flight requirements still need their own compliance check.
21. Payload limit comes from DJI Agras
DJI Agras recommends a tank payload limit based on current aircraft status and surroundings.
22. Do not exceed the current recommendation
Do not use tank capacity or a previous mission's payload as a substitute for the current app recommendation.
23. Shutdown order after landing
- stop the motors;
- power off the aircraft;
- then power off the remote controller.
24. Why controller-off-first is risky
If the remote controller is turned off while the aircraft remains powered, signal loss can trigger Failsafe RTH.
25. Confirm motors are fully stopped
Do not approach the aircraft as if landing alone means propulsion is safe.
26. Motors can be hot after operation
The safety guideline warns not to touch motors directly after use because of burn risk.
27. Let hot components cool before hands-on inspection
Use visual checks first and avoid immediate contact with heated propulsion components.
28. Aircraft ports must be used according to specification
Do not improvise connections to aircraft-body ports.
29. Waterproof covers belong back on unused ports
Attach the waterproof cover when a port is not in use.
30. Do not short-circuit aircraft-body ports
The source explicitly warns against it.
31. Damaged parts: do not improvise repairs
DJI says not to attempt aircraft repair when parts are damaged; contact official support or an authorized dealer.
32. Sprinklers are delicate parts
Clean them immediately after use.
33. Hose nuts must be tight
Loose hose connections create a separate spraying-system safety issue.
34. Respect minimum hose bend radius
Do not force hoses into bends tighter than their intended geometry.
35. In-flight monitoring checklist
- VLOS maintained;
- area remains clear of unauthorized people;
- app status monitored but not blindly trusted;
- obstacles visually monitored;
- battery warnings acted on promptly;
- payload state monitored;
- power lines kept clear;
- night spotlight not stared into;
- abnormal aircraft behavior triggers return/landing.
36. Post-flight shutdown checklist
- land in safe area;
- stop motors;
- power off aircraft;
- power off controller;
- allow hot motors to cool;
- inspect for damage;
- clean sprinklers if used;
- replace port covers;
- preserve warnings/logs if abnormality occurred.
37. What to do after a battery-related abnormality
Record the exact warning, battery identity, temperature/context and landing behavior before moving to battery diagnosis.
38. What to do after power-line contact
Do not touch the aircraft. Treat the scene as an electrical hazard and follow the appropriate emergency/utility response process.
39. What to do after obstacle-sensing underperformance
Do not immediately conclude sensor hardware failure. Preserve conditions, contamination/weather context and app warnings for diagnosis.
40. What to do after a propulsion finding
Route the issue into the propulsion branch rather than continuing normal operations.
41. T100 service routing
For T100 operators, use propulsion, radar/RTK/sensor or spraying-system collections after the affected subsystem is identified.
42. Common error: relying completely on obstacle sensing
The source specifically warns against this.
43. Common error: turning off the controller first
This can create signal loss while the aircraft is still powered.
44. Common error: ignoring low-battery warning because the field is almost finished
DJI says return promptly.
45. Common error: touching an aircraft on a power line
Do not touch it.
46. Common error: touching hot motors immediately after landing
Burn risk exists.
