Failsafe

Assistance for configuring the failsafe settings for the drone in emergency situations.

FlytBase offers a number of failsafe mechanisms to aid in safe and controlled emergency landings in events where vehicle control is lost.

  • Once the drone has been added and is online on the dashboard, click on Settings from the right corner of the screen.

Settings
  • In Settings, select a drone from the drop-down box at the top left corner. Now, click on Failsafe to view and configure failsafe settings.

Failsafe settings for the selected drone

Failsafe Actions

This table is an outline of the available failsafe events and their behaviors. Users can set the failsafe actions and trigger values (time/percentage) as per their flight environments.

Failsafe Event
Behavior

Actions

Low Battery Failsafe

The drone will perform the set action when the drone's battery percentage drops below the specified configurable threshold.

It is to prevent the drone from crashing or getting lost due to a depleting battery. When the battery level drops to the set battery failsafe percentage, the failsafe is triggered. This prevents the drone from reaching critical battery far from home/Docking Station. But when action is set to "No Action" then the drone will continue the mission.

RTH/RTSL

RTDS Land No Action

Critical Battery Failsafe

The drone will Land when the drone's battery percentage drops below the specified configurable threshold.

It automatically initiates the landing process when the battery level reaches a critical level, as the drone's battery is too low to perform any action. This ensures that the drone doesn't run out of power mid-flight, potentially causing damage or harm to the drone and the surrounding.

Land

Drone LTE Link Loss

The drone will perform the set action if the network connectivity on the device running the FlytBase Mobile Application or FlytOS is lost for the specified configurable threshold.

This occur because distance from the drone to the LTE network tower, environmental interference, signal obstruction, or hardware issues, contribute to the loss of LTE link.

RTH/RTSL Land Hover FN-RTH No Action

RC Link Loss

The drone will perform the set action if the connection between the drone's RC and the drone's autopilot is lost.

It can be due to interference from other radio frequencies or obstacles in environment, or RC reaches low battery, or is out of range. Therefore, it is important for the operators to maintain a strong RC link with the drone in order to maintain control.

RTH/RTSL Land Hover No Action

FlytBase Link Loss

The drone will perform the set action if there is a weak internet network connectivity on the FlytBase web page or is closed on the device while running the mission.

Occurs when the FlytBase dashboard is no longer connected cloud through the internet. As the operator loses visibility and drone controls when their dashboard is disconnected, this failsafe event becomes crucial.

RTH/RTSL Land Hover No Action

FN Low Battery

The drone will avoid NFZs in its path while performing RTH when the drone's battery percentage drops below the configured low battery. This setting is available for NFZ only.

It is to prevent the drone from crashing or getting lost due to a depleting battery. When the battery level drops to the set battery failsafe percentage, the failsafe is triggered. This prevents the drone from reaching critical battery far from home/Docking Station. But when action is set to "No Action" then the drone will continue the mission.

FN-RTH

No Action

Precision Landing Timeout

The drone will perform the set action if it is unable to detect the Precision Landing tag or maintain its position over the tag till the specified configurable threshold.

When the drone is unable to precisely detect the tag while hovering over or sustain its position over the tag leads to the drone failing to land in the docking station/ home location and this triggers the Precision Landing Timeout fail safe.

Failsafe Actions

This table outlines the available failsafe actions and their behaviors. Users can set the failsafe actions as per their flight environments.

Failsafe Action
Behaviour when Action is executed

Return To Home (RTH)

The drone will proceed to its home location and land.

Land

The drone will land at it's current location.

No Action

The drone will continue with it's set actions.

Return To Docking Station (RTDS)

The drone will proceed to the marked Docking Station Location to precisely align, approach, and land on the ArUco Tag on the Docking Station.

Return to Safe Location (RTSL)

The drone will proceed to the marked Safe Location and land.

Hover

The drone will hover at its current location and the user is required to take back manual control of the drone from the FlytBase dashboard or from the RC.

Preset Land Location

The drone will proceed towards a predetermined location set by the user and land there.

Failsafe Actions Expected Behaviors

Low Battery Failsafe

Failsafe Actions can be aborted by clicking Abortafter the connection is regained for Drone LTE link loss, RC link loss & FlytBase link loss.
