Micro-UAV Safety Guidelines & Checklists

Author: Xuan Wang

Updated 2025-01-06, v2

Disclaimer: The guidelines and the checklist are for educational purposes only in the course ROB498. All the flights should be conducted in room MY580 under the supervision of the professor / TA(s). Individual and/or outdoor flights are NOT ALLOWED; outside flight would very likely lead to violation of the law as defined by Transport Canada.

Please read this document carefully! It is recommended to keep a hard copy of this file on hand while working on/flying your drone. Failure to follow the safety rules/guidelines could cause serious injury to personnel or damage to the Myhal building and equipment.

Safety Guidelines (while working on your drones):

  1. Charging the battery:
    Battery type: LiPo (4S), Charging Current: no greater than 2.3 A.
    Different charging settings may reduce battery life or even cause a fire.
  2. Assembling the drone:
  • Exposed PCBs and solder joints should not be in contact with the carbon fibre frame (may be conductive).
  • Always ground/discharge yourself before touching any exposed PCBs.
  • Make sure all the screws are properly tightened as vibration during flight will loosen them.
  • Be very careful with the fragile white JST connectors.
  • Make sure the flight controller (Pixhawk) is tightly attached to the frame, fairly close to CG. If you have to install the Pixhawk in a direction other than the forward-pointing direction, please configure this setting in QGroundControl.
  1. Testing the motors:
  • Never install propellers before the aircraft is flight-ready!
  • Be careful with long hair that can become intertwined with motor shaft.
  1. While other teams/drones are flying:
  • Never turn on your transmitter (The Taranis remote control) as this could cause signal interference.

Pre-Flight Checklist

Please follow in sequential order. DO NOT plug in the battery first.

Aircraft Check
☐ Propeller direction check.
☐ Propellers are installed tightly on the motor shafts.
☐ The battery is fully charged and tightly strapped down.
☐ All components are tightly attached to the frame.
☐ All wires are clear from all propellers and the propellers spin freely.
Aircraft Start-up
Action: Transmitter Start-up
☐ The Throttle Stick is in the down position and all switches are forward.
☐ Flight Mode Switch is in the stabilize position.
Action: Battery Plug-In
☐ Transmitter signal strength confirm.
☐ Arm/disarm check.
☐ Manual fail-safe switch check.
Team & Surrounding Area Check
☐ Flight area cleared.
☐ All team members are wearing safety glasses.
☐ Protection net has been secured.

Post-Flight Check

☐ Keep the transmitter turned on with disarm / fail-safe switch active before unplugging the battery.
