Learning how to read a sectional chart is one of the most foundational skills every student pilot must develop before they ever leave the traffic pattern. The sectional aeronautical chart is the primary navigation tool for VFR pilots in the United States, and understanding how to interpret its symbols, colors, and data is not optional — it is a core competency that the FAA expects you to demonstrate on both your written exam and your practical checkride.
At Savannah Aviation, our experienced flight instructors introduce sectional chart reading early in the training program so that students build genuine map literacy alongside their stick-and-rudder skills.

Many student pilots feel overwhelmed the first time they unfolded a full sectional chart. The dense layer of symbols, magenta and blue lines, altitude numbers, and airport identifiers can look like a foreign language. But this guide will walk you through the essential components systematically, so that the chart begins to make clear, logical sense.
A sectional aeronautical chart is a 1:500,000 scale topographic map specifically designed for aviation use. The FAA publishes sectionals for the entire contiguous United States, Alaska, and Hawaii, and each chart is updated on a 56-day cycle to reflect changes in airspace, navigation aids, obstacles, and airport data. Flying with an outdated sectional chart is not just poor practice — it can create genuine safety hazards if airspace boundaries or restricted areas have changed.
The term "sectional" comes from the fact that the United States is divided into sections, each covered by a separate chart. The charts are named after major cities in the region they cover — for example, the Jacksonville Sectional covers much of coastal Georgia and Florida, which is the relevant chart for pilots training in the Savannah area.
While many pilots today use digital sectionals through apps like ForeFlight or the FAA's own SkyVector, student pilots are strongly encouraged to develop proficiency with the paper chart first. Understanding what you are looking at on a paper sectional gives you a much deeper comprehension of the data than simply tapping a touchscreen. During your written exam and checkride, you may be expected to work directly from a printed chart or a printed excerpt.
One of the first things you will notice about a sectional chart is its use of color to communicate terrain elevation. The chart uses a gradient system — greens represent lower elevations near sea level, progressing through yellows and tans into browns and grays for higher terrain. This color coding allows a pilot to immediately assess the general topography of an area at a glance, which is critical for terrain avoidance and obstacle clearance planning.
Elevation figures printed on the chart represent the highest terrain or obstruction within a given latitude/longitude grid square. These figures are called Maximum Elevation Figures (MEFs), and they are shown in large blue numbers in each quadrant of the chart. An MEF of 28, for example, means the highest obstacle in that square tops out at approximately 2,800 feet MSL (the digits represent hundreds of feet, with the smaller raised digit representing hundreds). When planning a flight, VFR pilots typically add a minimum of 1,000 feet above the MEF as a comfortable terrain clearance buffer.
Beyond the MEF figures, the chart also uses brown contour lines to show changes in terrain elevation. These lines connect points of equal elevation and help you visualize hills, valleys, and ridgelines across your route. Spot elevations — specific elevation figures printed at mountain peaks or prominent high points — give you precision data for the highest terrain features in a region.
Airspace depiction is arguably the most critical element of sectional chart reading for a student pilot, because flying into the wrong class of airspace without authorization is a serious regulatory violation. Sectional charts communicate airspace boundaries through a combination of line styles and colors, each carrying a specific meaning.
Special use airspace is also critical to understand. Prohibited areas (shown as blue P-designation boxes) are permanently off-limits. Restricted areas (blue R-designation boxes) require permission or avoidance when active. Military Operations Areas (MOAs) are depicted by magenta hatching and should be checked for activity via NOTAMs or Flight Service before transiting.
Airports are among the most frequently referenced symbols on a sectional chart, and the chart packs a remarkable amount of information into each airport depiction. Understanding how to extract that data accurately is an essential part of flight planning.
The shape and color of an airport symbol tell you immediately what type of facility you are looking at:
Adjacent to each airport symbol is a data block that contains several key pieces of information stacked in a standard format:
Being able to quickly read an airport data block allows you to assess whether an unfamiliar airport is a viable diversion option — a skill that becomes critical during cross-country navigation and emergency planning.
Even in the era of GPS navigation, sectional charts still depict traditional ground-based navigation aids that student pilots need to understand. VOR stations (VHF Omnidirectional Range) are shown as a compass rose symbol with the station's name, frequency, and identifier printed nearby. The 360-degree compass rose printed around each VOR helps you visualize radials and plan VOR navigation courses.
Each VOR on the chart is accompanied by a Victor Airway network — depicted as blue lines connecting VOR stations. These airways are 8 nautical miles wide (4 nm on each side of the centerline) and serve as navigational highways for IFR and VFR pilots alike. Even if you are not flying IFR, understanding Victor Airways gives you a useful framework for route planning and position reporting.
GPS waypoints and intersections are also depicted on modern sectionals as five-letter identifiers at specific geographic coordinates, providing additional reference points for navigation planning and ATC position reporting.
One of the most safety-critical elements on any sectional chart is the depiction of man-made obstacles. Communication towers, wind turbines, power lines, and other tall structures are marked with specific symbols — typically small tower icons in blue (for obstacles under 1,000 feet AGL) or with a group of icons for multiple closely-spaced obstructions.
Each obstacle depiction includes two altitude numbers: the top altitude in MSL (above mean sea level) and, in parentheses below it, the height AGL (above ground level). For example, a tower marked as 1,247 (349) has its top at 1,247 feet MSL and rises 349 feet above the ground. High-intensity lighting on an obstacle is indicated by a flashing symbol. Always check for obstacles along your entire route of flight, not just near airports.
Once you are comfortable with the individual elements of a sectional chart, the real skill development comes from integrating all that data into a complete route of flight. When planning a VFR cross-country, you will use the sectional to identify your departure and destination airports, plot a course line, check for airspace along the route, identify terrain and obstacles, note VOR or GPS waypoints for navigation, and select diversion airports at reasonable intervals.
At Savannah Aviation's flight school, instructors walk students through this complete planning process during ground school sessions before the first cross-country flight is ever attempted. The goal is to ensure that by the time you sit down to plan your solo cross-country, reading the sectional feels as natural as reading a road map.
