Emergency Procedures:

• Imminent Emergency: 911

• Privacy offence: Local police

• Fly away or loss of control - Local Aviation Authority (Refer to CFS)

  • This applies to both vertical and horizontal fly aways

In the event of a control station failure, the following steps should be taken:

• Attempt to restart the transmitter

• Use spare transmitter to communicate to drone

• If unable to establish communication with the drone, follow lost link procedures

• Battery

  • Do not fly if the battery appears dead or a problem is suspected. Puffy batteries should be ignored

• Transmitter should be verified before flight

• Props

  • Ensure in flight worthy condition (ex: no dings, etc)

• Control Surfaces

  • Smooth, verify servo control, pushrod integrity

In the event of an RPA failure, the drone should be disarmed - this will stop all motors. The following steps should be followed:

• Secure the area where the RPA will land

  • Do NOT fly the drone over an area where the RPA can unexpectedly land for this reason. Thus, flying over people is NOT permitted in this drone

• Secure the drone and disconnect the battery

• Do NOT fly the drone until inspected

In the event of loss of transmitter link, the pixhawk will activate return to home mode. If the RTH mode does not engage, initiate fly away procedures

In the event a fly-away occurs (both vertical and horizontal), the following procedures should be taken:

• Attempt to regain communication by following lost link procedures

• If unsuccessful, record last heading, speed, and altitude

  • Additionally, know the last battery level to estimate flight time

• Alert local aviation authorities about new flight path and potential conflicts

The flight may be terminated by disarming the drone - this will stop all motors. This should be used with caution as the aircraft will be rendered inoperable and unable to glide under control.
