Why
Water can bridge electrical contacts, corrode components and interfere with vision sensors. Even if a drone survives one wet flight, delayed corrosion can cause a later failure. Check the exact IP rating in your aircraft manual—marketing phrases like “weather resistant” are not the same as a tested ingress-protection rating.
What to do next
- 01Land as soon as rain begins; do not rely on obstacle sensing in poor visibility.
- 02Disconnect the battery after landing and dry the aircraft at room temperature.
- 03Do not charge or reuse a wet, swollen or damaged battery.
- 04Follow the manufacturer’s inspection guidance before the next flight.
Important exceptions
- Some enterprise aircraft publish an IP rating and approved operating envelope.
- Mist, sea spray and wet snow can be as harmful as rain.
- Legal visibility and cloud-clearance rules may stop the flight before the hardware limit does.
