The most important symbols are going to be those involving obstructions, airports, and symbols that will mean higher levels of manned air traffic. The next type of symbol we will look at are symbols that relate to physical obstructions or points of reference on the ground. An aeronautical chart is the road map for a pilot flying under Visual Flight Rules (VFR). Here’s my disclaimer: This may be the single most important section in this entire series. This is way more of a hazard when flying a drone than most fixed wing aircraft. This  type of hashed line does not indicate any type of airspace, but will always have something like this  at the middle to show manned pilots that there is a navigational aid there. Knowing how to read a sectional chart is really important for drone pilots that want to pass the Part 107 test and it is probably more applicable to your actual flying than you might think. Thus, let’s break them down into fundamental terms: Class G is specified as uncontrolled airspace. Being able to read sectional charts is one of the more essential skills that a drone pilot should have. Always obtain clearance prior to entry. This is mainly to help IFR flights with ATC contact since they wouldn’t get that in Class G airspace. By developing this skill, a drone pilot gets to understand the nature of airspace hazards, topography, airport data, controlled airspace. Some of the basic elements of a sectional chart are: A legend is a table consisting of symbols, numbers, colors and what each one of them means. These are really only good for pilots as a landmark or in the event of an emergency. The aeronautical information on Sectional Charts includes visual and radio aids to navigation, airports, controlled airspace, restricted areas, obstructions, and related data. The broadest distinction that one needs to know about the national airspace is the difference between controlled, uncontrolled, and special use airspace. Thus, if the MEF for a quadrant on a chart is 48,000ft, then on the chart it would appear as the number 48 written in a big blue font. So here, “46” indicates that the longest runway is 4,600 feet long. Now a sectional chart covers a good bit of airspace. The blue arrow is pointing to the dashed magenta ring, which represents that, inside of the ring, Class E airspace goes down to the ground. ERCs-L, ERCs-H and TACs are presented at various scales and depict airspace, air routes and radio navigation facilities. However, class G is not represented on a sectional chart. The lower number will always be in parentheses. Terminal charts contain additional details about approach, departure, transitions, and procedures for Class B airspace around airports. This airport is for public use but has no hard-surfaced runway longer than 1,500 feet. The chart provides information that allows pilots to trac… Symbols shown are for World Aeronautical Charts (WAC), Sectional aeronautical charts and Terminal Area Charts (TAC). In the white box above the Pensacola airspace, it says to contact Pensacola Approach within 20 NM on 118.6. This magenta flag  indicates a VRF checkpoint, and the black words “BUCKEYE LAKE” provide the name of the checkpoint. Here it is 120.15. In the picture below, the lake is the light blue section, and the river is the snaking blue line. This  is a rock quarry. I think a lot of people are seeing practice questions like this from the FAA’s sample UAG exam, and they’re trying to figure it out if they really need to be able to interpret a Sectional Chart during the UAG Part 107 Aeronautical Knowledge Test. The FAA is the source for all data and information utilized in the publishing of aeronautical charts through authorized publishers for each stage of Visual Flight Rules (VFR) and Instrument Flight Rules (IFR) air navigation including training, planning, and departures, enroute (for low … However, class G is not represented on a sectional chart. 16.687 • All airspace from 18,000’ MSL to FL600 (60,000’) • To enter Class A you must – Be equipped and rated for instrument flying – Be on an instrument flight rules plan (“IFR”) – … By continuing to use this site, you agree to our use of cookies. These are easy points. This Chart User's Guide is an introduction to the Federal Aviation Administration's (FAA) aeronautical charts and publications. Airspace & Chart Reading for Drone Pilots. In men with no vascular problems, this poses the little problem as the body quickly produces more to replace it. How to Read a Sectional Chart Over the last few weeks, I’ve been getting a lot of questions about how to read a VFR Sectional Chart. Either way, know that it exists. It is useful to new pilots as a learning aid, and to experienced pilots as a quick reference guide. If you open up a sectional, you will see this type of airport all over the place. Notice that this airport is not a circle. I would estimate that somewhere between 30% and 40% of the questions I answered on my most recent Part 107 renewal included reference to a sectional. Sectional Charts are meant to only show a section of a flight region. This symbol is important because of the open dot within the circle. Firstly, by noticing the folds created on the represented terrain. The bottom number in parentheses, in our example 305, indicates the height above the ground. The controlled airspace around Sandpoint begins at 700 ft AGL. When Class E Airspace extends down to the surface, the sectional shows a faded magenta line (thats the 700 AGL to 17,999 MSL) but will also show a dashed red circle. Class D airspace will begin at the ground and extend upward. The elevation of Sandpoint Airport is 2131 ft MSL as indicated by the airport data. Tall, man-made structures and natural landmarks are indicated along with roadways, rivers and railroad tracks, as these are easily seen and recognized by pilots from the air. Any drone pilots looking to further their knowledge of the National Airspace System. If they’re absent, then it is the class G airspace. Everything excluding A, B, C, D or E falls under the class G airspace. The ceiling in Class D airspace is shown by the  symbol, where the number represents the ceiling in hundreds of feet. If you’ve ever seen a sectional chart, at first they are very complex and confusing. Sectional Charts: Airspace . The NO SVFR symbol means that this airport prohibits fixed-wing Special VFR operations. Learning how to read a sectional chart will take some time, mostly because it appears so completely overwhelming at first. Civilian land airports will have a green and white rotating beacon. To use Sectional Charts for navigation. In the case of MEF being 12,500ft, for instance, it would be written as 125. airspace guide usa chart reading tutorial c aviation, sectional chart airspace classification overview aerial guide, what would be the airspace class when no vignette is visible, reading a sectional chart vfr map study pilot training, what is the thick dashed magenta line on a sectional chart Thus, to identify a class G airspace, one must first look for signs of any of the 5 controlled classes. If the diamond had an “H” inside it, the symbol would indicate hang glider activity. 4 hours of videos specifically designed for drone pilots; Contains information for both Recreational and Commercial (Part 107) Drone Pilots; Detailed information to become an expert in identify airspace and reading charts The Maximum Elevation Figure (MEF) on a sectional chart tells pilots what is the lowest altitude they can safely fly up to without posing a risk of colliding with objects. First, you need to know that Class E airspace is always going to be on a sectional chart using above ground level (AGL) as a measurement instead of mean sea level (MSL). The C inside a circle indicates that the UNICOM is also the Common Traffic Advisory Frequency or CTAF. There’s just no way around it. However, a terminal chart is more detailed than a sectional chart and is scaled at 1:250,000. chart while planning a flight or during a flight. How to read a sectional chart for drone pilots airspace. The basic symbols and numbers listed above can help us understand the details of the airport. When a symbol is different on any VFR chart series, it will be annotated as such (e.g. Anyone with a Remote Pilot Certificate looking for clarification on airspace. In the United states, each airport has a three digit code. When you see this information on a sectional, it may just look like a jumble of numbers and letters because, sometimes, that’s what it is. Most of the time though, when towers are above 1,000 AGL, they will have lightning bolts coming out from the top like this , which just means it has a light. This airport has a lot going on but I’m only going to address one part of this symbol here. OVERVIEW This packet includes several steps on how to plan a successful flight using an aeronautical chart. How To Get UIN For Your Drone Through Digital Sky, Drone Pilot Training Schools in India | 2020 Complete List. Thankfully, with practice and time, you can understand what any symbol represents and how to find more information about it. While I have an entire section of this guide devoted to airspace, this sectional will outline the markings on a sectional chart that show the types of airspace and their altitudes because this is a really important part of learning how to read a sectional chart. The charts are names by the way for the largest airports really within it's boundaries. For obstructions that are higher than 1,000 AGL, the symbol will look like this . Refer to it on every question that uses a sectional chart even if you are sure of the answer. There is no easy way to remember this. This  is an outdoor theater. The Control Tower (CT) Frequency given is 123.7. These are all pretty self explanatory but I’ll go over them briefly here. Again, the  indicates the ceiling and the floor of the airspace within that ring. The above picture here covers two variations of Class E airspace. I’ll cover those first and get the remaining symbols after that. This airport has one hard-surfaced runway that is between 1,500 feet to 8,069 feet in length. Source: public domain . I think a lot of people are seeing practice questions like this from the faa s sample uag exam and they re trying to figure it out if they really need to be able to interpret a sectional chart during the uag part 107 aeronautical knowledge test.
