in some cases, the latest information on flight restriction zones and other airspace restrictions
Keeping this software up to date will also help to protect against cyber attacks.

Follow the instructions to update the built-in software (firmware). Always check that the software has updated correctly before going flying.

- Never drop anything from your drone or model aircraft while it’s flying
- Never carry any dangerous cargo on your drone or model aircraft
You must never carry any cargo on your drone or model aircraft that could be dangerous to people, property or the environment if there was an accident.

For example, never carry:
poisonous or corrosive cargo, such as acid or bleach
flammable cargo, such as petrol or oil, apart from what the engine needs for that flight

Make sure any equipment is secure
If you plan to carry any equipment on your drone or model aircraft, you must not go over the maximum take-off mass (MTOM). This is the maximum safe weight your drone or model aircraft can take-off and fly with. It includes fuel and any items or equipment attached to it.

You can find the maximum take-off mass in your drone or model aircraft instructions.

- Do not fly if the weather could affect your flight
Some of the things to look out for:

- strong winds could blow your drone or model aircraft off course or make it difficult to fly safely
- wind on the ground is often very different to the wind at height
- rain or other water, snow and cold weather could stop parts of your drone or model aircraft from working
- fog could mean you lose sight of your drone or model aircraft
- glare from the sun could mean you lose sight of your drone or model aircraft
- cold or wet weather could affect your ability to control your drone or model aircraft safely
- standing out in the sun could affect your ability to concentrate

Make sure your drone or model aircraft will work if the temperature is low
Follow the manufacturer’s guidance on the safe temperatures to fly at.

Some types of battery do not hold their charge as long in cold weather and this may reduce the amount of time you can fly.
