DJI Agras T70P: Procedimientos de Emergencia — Battery, C2, Propulsion, Crash y Fire
DJI Agras T70P: Procedimientos de Emergencia — Battery, C2 Link, Propulsion Failure, Crash y Fire
El DJI AGRAS T70P User Manual v1.0 (2025.11) dedica un chapter específico a emergency procedures porque cada failure mode requiere una response distinta. Critical battery, RTK/GNSS loss, C2-link loss, propulsion failure, uncontrolled flight, crash, flyaway y fire no deben resolverse con el mismo decision tree.
Resumen: critical low battery/voltage provoca automatic descent and landing que no puede cancelarse. Critical overheating exige land o RTH immediately. Loss of RTK puede fall back to GNSS; si GNSS también desaparece, el T70P entra en Attitude mode y debe aterrizarse cuanto antes. Controller-signal loss por más de 3 seconds ejecuta la lost-signal action configurada. Single propulsion failure tiene una specific manual-flight direction; multiple propulsion failures are expected to result in a crash.
1. Emergency response begins by identifying the failure mode
Do not use one generic response for battery, navigation, C2 link or propulsion failures. DJI separates them deliberately.
2. Obstacle-avoidance emergency
Within its declared sensing boundaries, the aircraft can brake for detected obstacles.
3. If automatic braking does not occur
Use the remote controller to brake or avoid the obstacle manually.
4. Moving aerial obstacles
For another drone or manned aircraft, read DJI Agras prompts, observe the environment and manually climb or descend to create separation.
5. Do not wait for the obstacle system to solve every conflict
The manual treats pilot intervention as necessary when automatic behavior is inadequate.
6. Critical low battery
When the critical low-battery warning appears, the aircraft automatically descends and lands.
7. Critical voltage
The same forced landing behavior applies to the critical-voltage warning described by DJI.
8. The landing cannot be cancelled
This is a key difference from some noncritical RTH behaviors.
9. Critical overheating
If a critical overheat warning appears, DJI instructs the operator to land or Return to Home immediately.
10. Overheat is not a continue-and-monitor condition
The source calls for immediate recovery action.
11. RTK loss with GNSS still available
If fixed RTK positioning is lost, the aircraft can fall back to GNSS.
12. RTK loss is not automatically total navigation loss
Check whether GNSS remains available before classifying the event.
13. GNSS also lost
If GNSS becomes unavailable, the aircraft automatically enters Attitude mode.
14. Attitude mode supports manual flight only
Precise position hold is no longer available and the aircraft can drift.
15. Land as soon as possible in Attitude mode
DJI instructs cautious manual flight and prompt landing in a safe place.
16. C2 link loss threshold
If remote-controller signal is lost for more than 3 seconds, the aircraft executes the configured lost-signal action.
17. Default lost-signal action
The manual identifies RTH as the default.
18. Alternative lost-signal actions
The system can also be configured to land or hover.
19. Failsafe RTH
If lost-signal action is set to RTH, the aircraft enters Failsafe RTH.
20. Link restored during return
If the connection is restored, the operator can cancel RTH and regain control when appropriate.
21. Single propulsion failure
DJI provides a specific manual-flight response rather than treating any single-motor failure as immediately uncontrollable.
22. Flight direction after one propulsion failure
Adjust the flight direction so the aircraft flies forward along the arm with the failed motor.
23. Then return or land manually
Use that controlled direction to return home or land as safely as possible.
24. After landing from a propulsion failure
Photograph the site, preserve evidence and upload complete flight logs.
25. Contact official support or an authorized dealer
Do not return the aircraft to normal service based only on a visual motor replacement decision.
26. More than one propulsion motor failure
DJI states that the aircraft is expected to crash.
27. Multiple-propulsion failure is not a normal recovery scenario
Focus on protecting people and property rather than preserving the aircraft at all costs.
28. Aircraft out of control near people/buildings
If a crash toward a crowd or building is possible, DJI instructs evacuation of people within a 50 m radius.
29. First attempt: hover
Attempt to stabilize/hover the aircraft if possible.
30. Second attempt: Smart RTH
If hovering cannot resolve the situation, attempt Smart RTH when available.
31. Emergency motor stop as last-resort risk reduction
If the aircraft cannot hover and RTH cannot be triggered, DJI gives the emergency stop command: hold C1 + C2 + Flight Pause until the motors stop.
32. Emergency motor stop intentionally causes a crash
Use it only when that crash is expected to reduce a greater risk to people or property.
33. After an aircraft crash
Evacuate a 50 m radius, photograph the crash site and upload complete flight logs.
34. Do not reuse the flight battery after a crash
DJI says to remove it from service.
35. Crash-battery placement
Place the battery in an open area away from flammable materials and contact official support or an authorized dealer.
36. Do not treat a crash battery as a normal charging fault
Physical-impact history overrides routine charging diagnostics.
37. Flyaway search
Use the aircraft and controller positions displayed in DJI Agras to search for the aircraft.
38. If GNSS was lost
Estimate the likely area from the last known position, speed and heading.
39. Record flyaway details
- aircraft model;
- time of loss;
- last known location;
- task status;
- direction/heading;
- speed if known;
- controller location;
- GNSS/link status.
40. Contact support with evidence
A complete incident record is more useful than a general statement that the aircraft “disappeared.”
41. Fire: first protect people and surroundings
Move nearby flammable materials more than 5 m away when it is safe to do so.
42. Controllable fire
The DJI manual describes using a large amount of sand and water cooling, followed by complete battery discharge using its specified disposal procedure. Because battery-fire response can be hazardous and local emergency requirements vary, follow the manufacturer procedure together with applicable emergency guidance rather than improvising.
43. Uncontrollable fire
Move flammable materials away, extend the safety distance to more than 10 m and evacuate people until the battery fire is extinguished.
44. Do not approach a battery fire unnecessarily
Preserving the aircraft is secondary to human safety.
45. Battery disposal after an emergency
The battery chapter provides a manufacturer disposal process and directs operators toward appropriate recycling channels. Use the exact current manual/support guidance for the affected battery rather than inventing a disposal method.
46. Emergency incident log
- event type;
- time/location;
- aircraft ID;
- battery ID;
- DJI Agras warning;
- GNSS/RTK state;
- C2 link state;
- propulsion state;
- pilot response;
- crash/fire status;
- photos;
- flight logs uploaded.
47. Service handoff after emergency
Do not choose replacement parts from the warning name alone. Use physical inspection and logs to identify the affected subsystem.
48. Propulsion event
Inspect motor, propeller, ESC-related components and structural arm condition before selecting parts.
49. Sensing/navigation event
Separate RTK/GNSS or sensor behavior from actual propulsion damage.
50. C2-link event
Review controller, antenna, firmware, OcuSync and transmission history before replacing aircraft hardware.
51. Battery event
Physical damage, overheating or crash history may require battery isolation rather than normal service.
52. Common error: cancelling a critical battery landing
The manual says it cannot be cancelled.
53. Common error: treating RTK loss as complete navigation loss
GNSS may still remain available.
54. Common error: assuming every C2 loss means RTH
The configured action can be RTH, landing or hover.
55. Common error: replacing one motor immediately after a propulsion incident
Preserve logs and inspect the entire affected propulsion/arm branch first.
56. Common error: reusing the crash battery
DJI says not to reuse it.
57. Questions
Can critical-battery landing be cancelled?
No.
What happens if RTK is lost?
The aircraft can fall back to GNSS.
What if GNSS is also lost?
It enters Attitude mode; land as soon as possible.
When does lost-signal action trigger?
After more than 3 seconds of controller-signal loss according to the manual.
What if one propulsion unit fails?
Fly forward along the failed motor's arm direction and manually return/land.
What if multiple propulsion units fail?
DJI states the aircraft will crash.
