There are rules and regulations set forth by the FAA to safely share the sky with other aircraft. The drone can only go so high in particular air spaces. Checkout the B4UFLY app as a reminder of airspace. Larger aircraft will always have the right away.
Create a routine checklist to inspect the drone. If anything is found that is not normal immediately correct, or choose another drone ( if available) to fly to prevent a accident. Once your flight is complete scan the drone once again. If anything is found it can be fix before your next flight.
Get comfortable operating your drone on a consistent basis. Building confidence in your ability to use the remote controller, basic flying maneuvers, landing, moving left/ right, yawing motion, and visual awareness increase your skills.
Make your certain the battery is fully charged. Flying with a slightly charged battery could effect the flight. Having at least two charged batteries on hand will be a quick adjustment to ensure a safe flight.
Scan the entire flight area looking for powerlines, trees, buildings, objects, and guywires that could obscure a safe flight.
There are so many things that can go right a number of uncontrollable things that could go wrong once the drone is up in the air. Make a real commitment to personally engage in safe practices whenever you fly. Remain calm, confident, knowledgeable of drone rules, and every flight mission will be a great success.
