Luckily, the majority of mistakes on our list are the sort of common sense stuff that will make perfect sense to avoid when you recognize the situation. The problems may be straight-forward, but you might be surprised at how and when they show up — allow us to help you prepare for most potential eventualities from the sky.

 

There are drone laws

Fly legally

You need to register your drone with the FAA before you fly!

You need a drone license before you fly!

Most drones do not come with a set of instructions on what you are and are not allowed to do with them. This is not a problem in most places around the globe, but in the United States, every craft that weighs 0.55 pounds or more must be registered and follow strict aeronautical guidelines. We have explored these before, and will do so time and again, but the short version is as follows:

Basic drone flight guidelines in the United States

  • Fly at or below 400 feet above the ground
  • Always fly within line-of-sight, if you can’t see it, bring it in
  • Stay away from airports
  • Stay away from airplanes – they have the right of way in the air
  • Do not fly over people
  • Do not fly over or close to sports events or stadiums
  • Do not fly near emergency situations such as car crashes or building fires
  • Do not fly under the influence
  • Be aware of controlled airspace – use the B4UFly app
  • Your drone will need a Remote ID broadcast transmitter

The short version of the controlled airspace situation is that you cannot fly within 5 miles of an airport, at least not without first receiving authorization from local air traffic controller for where and when you will be flying. You need to use the LAANC tool, found within apps like Airmap or KittyHawk. The FAA has a list of no-fly-zone areas that should help you keep safe and legal.

If you are flying for pay, or any other form of compensation, you must operate under a different set of rules and possess a commercial drone license. We call it the Part 107, it’s not too hard to get, but it will take some time to learn all the rules. We want to help you learn the rules and get your commercial license, check out our drone pilot training material.

Bottom line, you cannot just go outside and fly wherever you wish, unfortunately. The rules are fairly easy to comply, just think safety and hopefully the rules don’t deter you.

Flying smart

Have a good attitude

Not just an approach for a healthy lifestyle, there are certain attitudes that lead to risks when flying your drone. The FAA specifically calls these out in their materials, what I’m saying is, if you are studying for your Part 107 certification exam, pay attention, here are some of the answers.

According to the FAA you should avoid the following attitudes:

Antiauthority – A tendency to believe the rules do not apply to you.

Impulsivity – Unwisely taking action before thinking through the result.

Machoism – A “hold my beer, I got this!” mentality, taking unnecessary risks. 

Resignment – A misbelief that you have no control over a situation.

In the end, the FAA is saying that you are the pilot, you are in control, and you need to conduct yourself safely and thoughtfully. It’s not like you have to log your complete flight plan before take-off or anything, just follow the rules and establish a personal set of guidelines for your flight — maybe you’ll decide to stay within an area, avoid the trees over there and remember that there are powerlines and people off to your left.

A more proactive action you can take is to set the max altitude setting in your drone app, it’s probably at 400 feet now. If your planned flight requires airspace authorization that only allows you to go up to 200 feet, go ahead and set that limit in the app and then you know you’ll stay legal.

Why patience matters

Be patient

Cheap Drones Guide

I understand the urge, I really do, you have a great new flying camera or toy drone and you want to put in the air as soon as possible. Please, do not throw caution to the wind, if conditions are not right, do not attempt to fly.

I learned this the hard way myself. I had a simple $30 drone that I just wanted to see how it handled, it was a windy evening, but I took the risk. No word of a lie, less than 45 seconds in the air, the wind was beyond the toy quadcopter’s capabilities and I had to go climb a tree to recover the thing. The very next morning conditions were perfect and I got to fly safely.

The tricky thing about wind, that you probably already know, but may forget in the heat of the moment, the higher up you fly, the stronger it is. Ground conditions may be acceptable, but that may not be true higher up, so take note before you fly.

Unexpected obstacles

Trees, light posts and power lines

I don’t have to tell you to stay clear of things like trees and power lines when you take to the sky, but these obstacles can quickly creep up on you during your flight. Wind is the leading cause of a drone veering off into the trees, but there are other factors that you should be aware of. For me, the second most problematic item is the convenient return-to-home (RTH) feature on many new drones.

First of all, you may be flying a drone at very low altitudes, with a high tree canopy above; sounds like no problem until the RTH feature initiates and you learn the hard way that it has a rather high automatic flight altitude. Most RTH modes take your drone to 60 feet (~20 meters) or more.

I had an experience once where I was manually landing a drone, I had it no more than 18-inches from the ground and was actually just hitting the joystick to take it down when the low-battery RTH mode kicked in. The drone shot 60 feet into the air, maneuvered less than 3 feet over and came back down to auto land. This drone did not allow me to override the RTH, I was at the absolute mercy of the auto-pilot – luckily I was taught to avoid taking off anywhere that has an obstacle above, but still, the neighboring trees were a lot closer than I wanted them. I never wanted that drone to go above 6 feet for that flight.

RTH produces another risk – this one should be more straight forward: most drones recognize that they are at point A, and home is at point B, if there is no obstacle avoidance sensors on the craft, you best ensure there are no obstacles between your drone and where it calls home.

Finally, consider your control range and potential interference. That toy class drone I mentioned earlier, the one I flew in the wind, into a tree, it has a rather small operating range, about 60 feet. It is easy to fly to the edge of its connectivity, and when it gets there, the drone doesn’t just stop, despite loss of connection to the controller, the drone just keeps going for a few of the longest seconds of your life, then cuts power and drops out of the sky. If the edge of your range is semi-close to a tree line or other obstacle, please be careful.

How far is too far?

Stay in range and be aware of controller interference

GDU Byrd Premium 1.0 review

I think I just explained this one – simple enough, most drones will advertise their effective operating range. When I say range, I am not talking about how much ground it can cover before the battery runs out, I mean the straight line distance between the controller and the craft. Stay within the listed range and be prepared to run toward your craft if you slip up.

As per the FCC, all radio frequency electronics in the United States must accept interference. While the FAA would like for anything in the sky to not experience interference, it happens. It actually happens a lot, get used to it and prepare for it. This is particularly true of video feeds if your drone is equipped with a FPV camera and live-streams video to your phone or the controller.

Obviously you should try to avoid flying places that have a high natural magnetic interference, it messes with the GPS. You will find that flying close to large structures, power lines or radio towers can be really bad. In these instances, your drone may fail to fly stable and you may actually lose control of the craft for spells of time – I hope I don’t have to tell you that that is a bad thing.

There are things you can do to mitigate these problems, but the simple solution is to consider these places unsuitable for flight.

Turbulance

Propeller wash

One of the most common mistakes a pilot can make is to fly too close to the ground. Keeping it low sounds like a safe thing to do, especially for first time pilots, but you are creating one of the least stable flying situations possible for a drone. It boils down to the physics of quadcopter flight. As the propellers spin, they move air downward with enough force that the craft can take off of the ground; when close to the ground, that air bounces back up to the craft.

Two things happen when you hover close to the ground: First, the drone is given an extra boost, that high pressure air helps keep the drone aloft, even though you don’t actually have enough throttle to sustain flight. You can test this with a nano drone in the house. Hover as low as you can on a table or counter, slowly navigate off the edge, the drone will drop to the floor, the propeller wash kept the drone from landing on the table, but there was not enough power to actually fly.

Hubsan Drones Guide

Second, and this is way more important, propeller wash is extremely unstable. I’ve seen drones hovering low that all of a sudden whip into a spin or even completely flip upside down. Remember, your drone is producing enough air flow to lift itself into the air; if that air bounces off the ground back up into your craft at a weird angle, strange things can happen.

For most drones, you should be safe once you are a few feet off the ground, but I might suggest what my DJI flight instructor taught me, take off, immediately go to about 7 or 8 feet in the air, hover while you re-asses your surroundings and see how things like wind are affecting your craft, then continue your flight from there.

Blown away in the wind

Wind and air temperature

I don’t want to get too technical here, but please keep in mind that wind and air temperatures will greatly affect your flight. Wind is really straightforward – it’s stronger the higher up you are, but it’s unpredictable, it’s powerful and it can make for a bad day. Another thing about wind you may not think about is how much battery power it takes for your drone to fight wind. Take note of wind direction and speeds before you take off, make sure you’ve got enough battery to get back.

Air temperature is not as straightforward. Related reading: Air density and drones – science of flight

Have you ever seen a hang-glider in action? What about an eagle or hawk soaring? These are made possible (largely) thanks to pockets of warm, rising air. Often found over hillsides, these thermals are extremely powerful when harnessed properly. There’s a good chance that your drone does not have a large surface, like a big airplane wing, to catch a thermal like this, but there is enough to make a difference.
