Too cold for a drone means below the lowest operating temperature its maker gives, and that limit depends on what powers the drone. Check it for your model before a cold mission.
Batteries in the cold
A battery drone's range usually drops in the cold.
Fuel cells in the cold
At system level, our hydrogen fuel cell systems keep full performance down to −20 °C. Our engineers give the values for each product. The energy is in the hydrogen tank, and refuelling takes about two minutes.
