Some of the most common questions we get from our students studying to pass their FAA Aeronautical Knowledge Test for a commercial Remote Pilot Certificate have to do with controlled airspace:
- What tools should I use to conduct airspace research?
- I’m using the B4UFLY app…is that a good app to be using?
- Can you help me understand whether or not I’m in controlled vs. uncontrolled airspace?
- Can’t I just contact the airport / air traffic controller directly to ask for authorization?
- What’s this I hear about an online portal and a 90-day wait-time?
- And what’s all this buzz about LAANC, UAS facility maps and instant airspace authorization?
Have additional questions about airspace authorization or FAA drone regulations? Post your questions to our community forum over here.
In this guide, we’ll help you understand how to request airspace authorization to operate in controlled airspace. Since this guide is written for both drone pilots who are interested or actively preparing for their FAA Aeronautical Knowledge Test AND drone pilots who already have their Remote Pilot Certificate and are trying to make sense of next steps, we’ll start with the basics.
We’ll teach you what controlled airspace is, how airspace authorizations are different than waivers, how long airspace authorization takes, and how to properly request airspace authorization.
So, without further ado, let’s get into the questions.

What is a Sectional Aeronautical Chart?
The Sectional Aeronautical Chart is the FAA’s official source of data when it comes to topographical features that are important to pilots operating in the National Airspace System (NAS).
Often just called a Sectional or Sectional Chart, these maps are updated every 6 months and show things like terrain elevations, airports, radio frequencies, latitude & longitude, and airspace classes.
Nashville’s (BNA) Class C Airport. The innermost magenta circle that surrounds the airport denotes controlled airspace from the surface up to 4,600 ft. mean sea level (MSL).
It’s the last item of interest, airspace classes, that we’ll be discussing in this guide.
How can I tell if airspace is controlled or uncontrolled?
As a student drone pilot is going through his or her studies, learning how to read and to interpret airspace on a Sectional Aeronautical Chart is an absolute must. Our students report seeing a disproportionate chunk of test questions (up to 30-40%) having to do with Sectionals, mostly knowing how to identify airspace classes, whether you can or can’t fly, and the ceiling and floor altitudes of those areas.
Needless to say, if you haven’t already been exposed to these charts, you will soon enough.
We have an entire lecture on this within our online Part 107 test prep course, and frankly it’s where our students spend the most time studying. Looking at these charts can be super intimidating at first, but after going through a handful of examples and understanding the different tools that are out there for you to research this stuff, it gets a lot more approachable / easier to do airspace research.
It’s all based on colors. If you’re flying into blue or magenta solid or dotted lines, that’s where you really need to start paying attention.
Check out this portion of the Sectional Aeronautical Chart legend, found on page 13 of the testing supplement that remote pilots need to reference during the FAA’s Aeronautical Knowledge Test. This shows you what colors match up with what airspace classes.
Bottom line — if you’re flying in controlled airspace, you need authorization.
What are the best apps / tools for researching airspace?
While you can buy a printed-out version of a Sectional Chart to hang on your wall from a website like My Pilot Store, most drone pilots are using apps on their computer, tablet, or phone to conduct airspace research.
Companies like VFRMap and SkyVector offer free, digitized Sectional Charts, allowing you to zoom in and out and click into airports to get more detailed information. It’s a great way to quickly scan the major airspace considerations of a particular latitude / longitude.
There’s also AirMap, another free tool which I like, because you can plug in an actual address. Same with Kittyhawk. I’ve used Skyward as well, but that’s more of a flight logging and operations management tool.
There are plenty others! Those are the top ones.
Should I use the B4UFLY app?
Oof, I get this question a lot. Short answer? No, not if you’re operating commercially.
The B4UFLY app was originally built for hobbyists, not professionals, and it’s simply not a great airspace research tool for certified remote pilots operating under the Part 107 rules, not when compared to the aforementioned tools. It’s not as intuitive, and the additional questions you might have when conducting airspace research can be hard to answer within just their app.
Here’s what the FAA says about their B4UFLY app:
Q. Is B4UFLY intended for commercial operators or hobbyists?
A. B4UFLY is really geared toward users of unmanned aircraft who fly for hobby or recreation. The app parameters are set up in accordance with the Special Rule for Model Aircraft (Section 336) in the FAA Modernization and Reform Act of 2012. However, we expect civil or commercial operators will also find aspects of the app useful, and we will consider future enhancements.

Using LAANC to request instant airspace authorization
LAANC, or Low-Altitude Authorization and Notification Capability, is a partnership between the FAA and private companies like Skyward, Kittyhawk, Airmap and DJI.
Here’s the full list of LAANC service providers:
Long story short, LAANC gives drone pilots the ability to apply for near-instant airspace authorization using a mobile/web application. The final installment of the program occurred in September 2018, successfully expanding LAANC to 288 air traffic control facilities and 470 airports across the United States.
How does LAANC work?
It’s remarkably easy. You open up an app, put in your mission details, and request access.
In a few years, these new instant authorizations will most likely be incorporated into a larger Unmanned Traffic Management (UTM) system, which will enable the safe operation of drones in what are becoming more and more crowded skies.
According to AINonline:
The LAANC system is considered a precursor to the comprehensive UTM (Unmanned Aerial Vehicle Traffic Management) system a NASA-led team is developing for transfer to the FAA by 2019. “The current process for meeting authorization and notification requirements of existing rules is manually intensive and therefore costly,” the FAA states in a draft LAANC concept of operations document released in February. “The FAA is seeking to close the gap of manual versus automated data transfer and authorizations by defining and establishing a technological solution that will allow for data exchange between operators and ATC.”
So that’s where things are headed.
It used to be a LOT more difficult to get these authorizations in general, but there’s still a ways to go before airspace authorizations become less of an administrative headache.
Speaking of which…
What happens when LAANC doesn’t work for me?
LAANC doesn’t work 100% of the time. Maybe the area in which you’re looking to fly isn’t appropriate for instant airspace authorization since there’s more air traffic there.
If you’re unable to get near instant approval with LAANC, you should fill out the FAA’s online airspace authorization form over here. After submitting the form the FAA “will strive to review and issue decisions on waiver/authorization requests within 90 days. Processing times will vary based on the complexity of your request.”
Make sure to read the instructions and to fill out the form correctly, or you either won’t hear back from the FAA or will be denied a request and will have to start over.
So how should you fill the form out?
First, if you haven’t already set up an account with FAADroneZone, make sure to go ahead and do that. This is the same account you’d be using for your recreational or commercial sUAS registration.
Then, once you’re logged in, click through to your Part 107 Dashboard, navigate to the Part 107 Waivers & Authorizations section, and click the button that says, Create Part 107 Waiver/Authorization.
Make sure to select the correct bullet point indicating you’d like to start an Airspace Authorization application.
You’ll notice that there are four parts to the application.
You need a primary title for your intended operation. My recommendation is to be clear and specific, so something like:
Ongoing Residential Roof Inspections in BNA Class C Airspace
This will usually just be you, but it doesn’t have to be. The Responsible Party is not required to hold a Remote Pilot Certificate and can be the representative of an organization.
The Responsible Party you put down is accountable for a list of responsibilities, which include maintaining records demonstrating compliance with FAA requirements; being accessible by the ATC; and maintaining a list of pilots and make / model of all aircraft involved in the operation. See the full list on pages 1 and 2 of this FAA instructions document.
This next section of the application is called Operation Parameters and has a bunch of information you’ll need to fill out.
Pay attention to all the form field instructions, like Dates cannot be in the past or exceed 24 months from today’s date.
When it comes to your Proposed Location of Operation, the more specific you can be here, the better. Provide city, state, and specific identifying characteristics, including landmarks.
Here is an example:
Project center point is intersection of ______________. Nearest street address is ______________. We intend to fly over the ______________ to capture photos and video for construction progress monitoring of the road/rail separation project. Flight will focus on bridge construction near this project center point as well as the railroad tracks affected by this project.
Use the Latitude and Longitude fields to identify the center point of your mission. The center point does not necessarily have to be where you are starting your mission, since factors such as weather and terrain may make starting in the center of your proposed area of operation impractical.
If you need help converting latitude and longitude decimal measurements for a particular location to the degrees, minutes, and seconds format needed in this application, you can use a conversion tool like https://www.latlong.net/lat-long-dms.html.
THIS IS IMPORTANT: A little known—but crucial!—best practice is to use the center of the airport as the GPS location and to request Blanket Area / Wide Area authorization for that airport’s entire controlled airspace. This is the clearest way to request the most amount of airspace around an airport possible.
Description of Your Proposed Operation, it’s important to note that the instructions for this open form field ask not just for a description, but also for “Purpose of operation and method by which the proposed operation can be safely conducted.”
Although FAA instructions for filling out the form state that this justification is only required for airspace waivers, and not airspace authorization, your best bet is to provide a clear safety justification for an airspace authorization request as well.
Here is the answer one of our students used for a successful application:
I intend to obtain site photographs/video of the construction progression at this location which was designed by COMPANY. The sUAS described within will be configured to limit vertical AGL altitude to 200ft and horizontal travel will remain within VLOS. We intend to utilize multiple launch points at this location to ensure the sUAS remains within VLOS. Aside from requesting to fly within this Class C airspace, we will comply with all other Part 107 regulations. In addition to complying with part 107, we intend to have a 2 man crew comprised of both a PIC & a designated VO to alert the PIC of any potential aircraft entering the vicinity. ATC can reach either of us if needed via our cell number provided in this request. PIC will also post a NOTAM via www.1800wxbrief.com, a minimum of 24-hour advance notice of this flight to inform pilots and ATC of specifics of the flight which will appear on sectional VFRs for any interested parties. We feel this request will benefit our project by allowing us the freedom to operate safely and as needed in this Class C airspace.
And here’s how another student adapted their paperwork for their specific request of Class D airspace authorization.
Proposed area of operations:
We request that we are able to fly in the Class D airspace around Sioux Gateway Airport (SUX), Sioux City, Iowa.
The airport coordinates are:
42-24-09.4000N / 096-23-03.7000W
42-24.156667N / 096-23.061667W
42.4026111 / -96.3843611
We intend to capture photos and video for clients who have property within the Class D airspace and have requested that we provide photos and videos of their property for various purposes such as marketing, construction and/or inspection. We agree that no flights will take place within 1 mile of the airport coordinates.
Description of your proposed operation:
We intend to obtain site photographs/video of various locations as requested by our clients during the upcoming summer months where our local weather permits the safe operation of our sUAS. The sUAS described within will be configured to limit vertical AGL altitude to 200ft and horizontal travel will remain within VLOS. We will ensure the sUAS remains within VLOS. Aside from requesting to fly within this Class D airspace, we will comply with all other Part 107 regulations. In addition to complying with part 107, we intend to have a 2 person crew comprised of both a PIC & a designated VO to alert the PIC of any potential aircraft entering the vicinity. We will give way to all aircraft and will be especially aware of our distance from runway approaches. ATC can reach us if needed via our cell number provided in this request. PIC will also provide a minimum of 24-hour advance notice of this flight to ATC of specifics of the flight: location, anticipated take-off time, anticipated end of operation, and current cell phone numbers of PIC and VO. PIC will also provide notice at the actual time of launch and landing of each flight to ATC if they so desire. We feel this request will benefit our project by allowing us the freedom to operate safely and as needed in this Class D airspace. The majority of the flights we anticipate will fall near the outer limits of the airspace.
After filling out this section of the application, you’ll be asked to review and then to submit your information to the FAA.
Once you submit your application, you’ll be given a reference number, and you’re able to check the status of your application at anytime by logging back into your Part 107 Dashboard and selecting the Manage Part 107 Waivers / Authorizations button.
How long does it take for the FAA to process your airspace authorization request when submitted this way? It depends, but normally a couple of weeks to the full 80-90 days.
And finally, here’s a real-world example of Class C Airspace Authorization paperwork, issued directly from the FAA.
What is airspace authorization, and how is it different from a 107.41 airspace waiver?
As an FAA-certified remote pilot under the Part 107 regulations, if you need to operate in Class B, C, D, or E airspace, you need to get prior approval to operate in that airspace.
According to the FAA Drone Zone:
- When applying for airspace authorization. “Use this to request access to controlled airspace. An airspace authorization is the mechanism by which an operator may seek Air Traffic Control (ATC) approval to operate in controlled airspace. Authorizations can be for a specific location or for broad areas governed by a single ATC jurisdiction.”
- When applying for an airspace waiver. Use this to request a waiver from 14 C.F.R. 107.41. Airspace Waivers may be issued where the applicant can demonstrate safety mitigations through equipage, technology and or operational parameters that their UAS can safely operate in controlled airspace without seeking ATC authorization prior to each operation. Processing times for airspace waivers are significantly longer than processing times for airspace authorizations.
If you want to fly in controlled airspace, your best bet is to look at LAANC first, then if that doesn’t work to apply for airspace authorization using the FAA Drone Zone portal.
Read the next section to learn about the difference between an airspace waiver and a Part 107 waiver.
Is this different than getting a “Part 107 waiver?”
Yes, and this is an important distinction.
The terms “waiver” and “airspace authorization” are often used in the same sentence, and it can seem like they are the exact same thing (the confusion is understandable, in part because until recently the FAA form to apply for them was the exact same form with two different check boxes).
In fact, many people get their application for one or the other rejected because they don’t properly understand which is which. Now that the FAA has separated Part 107 waiver requests into their own distinct form, we anticipate seeing less rejections of this nature.
So what’s the difference?
Part 107 (Non-Airspace) Waivers
To clarify, applying for a Part 107 waiver means that you would like to get permission to be exempt from existing Part 107 prohibitions and regulations, like not being allowed to fly at night, flying over people, or not being allowed to operate beyond visual line-of-sight (BVLOS).
Daylight Operations waivers are getting approved more frequently than any other type. You can see the full list of Part 107 waivers that have been approved over here.
So if you want permission to fly over people from 3-4pm on a specific day, or if you’d like to do one single BVLOS flight for an inspection, or if you’d like to fly at night so you can do an amazing drone light show as a backdrop to Lady Gaga rocking down the house (ok, so those drones weren’t flying live, but you get the idea), you can apply for a waiver that will temporarily exempt you from the Part 107 requirements.
Requesting airspace authorization, on the other hand, means that you are asking to operate / fly in controlled airspace, or for drone pilots, Class B, C, D, or E:
- Class B airspace is generally airspace from the surface to 10,000 feet mean-sea-level (MSL) surrounding the nation’s busiest airports in terms of airport operations or passenger enplanements. You can think of the “B” in Class B airspace as standing for “big city” airports.
- Class C airspace is generally airspace from the surface to 4,000 feet above the airport elevation (AGL) (charted in MSL) surrounding those airports that have an operational control tower, are serviced by a radar approach control, and have a certain number of instrument flight rules (IFR) operations or passenger enplanements. You can think of the “C” in Class C airspace as standing for “cities.” So not the big cities of Class B airspace, but still sizable city airports.
- Class D airspace is generally airspace from the surface to 2,500 feet AGL (charted in MSL) surrounding those airports that have an operational control tower. Small city airports with control towers are usually designated as Class D airspace. You can associate the “D” in Class D airspace with “diminutive” or “dime-sized.”
- Class E airspace almost always has one of four lower limits: the surface, 700 feet AGL, 1,200 feet AGL or, in some sparsely populated areas, 14,500 feet MSL. Most of the country has a Class E airspace lower limit of 700 feet AGL and/or 1,200 feet AGL. The upper limit of Class E airspace is up to but not including 18,000 feet MSL, or when Class E airspace runs into the upside-down wedding cake airspace of Class B or Class C. For a drone pilot, if you’d like to operate in Class E airspace, you’ll need to get permission.
What if I need a Part 107 waiver AND airspace authorization?
If you are planning a flight that will require both a Part 107 waiver and airspace authorization—for example, night operations in Class B airspace—the order in which you get each is important.
“If you intend to use a non-airspace Part 107 waiver in controlled airspace (for example, night operations in Class B airspace), you must obtain your non-airspace waiver prior to requesting an airspace authorization or airspace waiver.”
So if you want to fly a mission that requires both a Part 107 waiver and airspace authorization, you must obtain your Part 107 waiver prior to requesting an airspace authorization or airspace waiver.
Since Part 107 waivers have historically been slow to process, you should prepare yourself for a long wait—especially since you’ll have to use the Part 107 waiver to then submit your airspace authorization request . . . and wait some more while that gets processed.
I heard I could just contact the airport / air traffic control directly…isn’t that faster?
On the FAA’s website, they state their position quite clearly:
How do I request permission from Air Traffic Control to operate in Class B, C, D, or E airspace? Is there a way to request permission electronically?
All airspace authorization must be made through the Low Altitude Authorization and Notification Capability (LAANC) or DroneZone.
Can I contact my local air traffic control tower or facility directly to request airspace permission?
No. All airspace permission requests must be made through the online portal.
