Where are chart supplements and legends in ForeFlight?

Special use airspace in ForeFlight

Important information like details on special use airspace can be found right on the moving map.

The ability to seamlessly stitch together dozens of charts into one endless moving map is certainly one of the iPad’s greatest strengths. No more folding paper charts and trying to transfer your route from one to the next.

There are some compromises that are made, though, when moving data that was initially designed to be displayed on a fold-out chart or book to an iPad app. In particular, it’s a challenge to integrate information like legends and chart supplements – some of which is critically important for pilots. Fortunately, ForeFlight still offers these supplements and supporting data, but you need to know where to look.

VFR Sectionals

  • Legends: every printed sectional includes a detailed legend on the outside back panel, depicting chart and airspace symbology. To access these legends in ForeFlight, go to the Documents section of the app, tap the Catalog button in the top right corner, and then select FAA from the left hand column. Now scroll down until you see the Legends header, and here you’ll find the VFR Chart Legend. Tap the blue arrow button next to this, and the VFR Chart Legend will be saved in your Documents.
  • Special Use Airspace: each printed sectional includes a table listing out the details of all the MOAs, prohibited, restricted alert, and warning areas. This is very useful for determining the altitudes and time of use for these areas, since they are not directly printed on the map. While ForeFlight does not have this table available directly in the app, you can still access this info fairly easily. When viewing a special use airspace on the sectional in the Maps tab, simply tap and hold your finger on it, and a small window will appear. Select the All tab at the bottom left of the window, and here you’ll see all the details for the airspace, including altitudes, controlling agency, frequency and times of use.

The majority of chart supplements and legends are found in the Documents section of ForeFlight.

Airport/Facility Directory

  • Supplement: while the individual entries for an airport are found in the A/FD section of the Airports tab, the A/FD supplements are found in the Documents tab. They’re in the FAA Catalog, under the Airport/Facility Directory header, and are separated by region. The A/FD supplements include information that’s tough to find in other resources, like contact info for ATC facilities, FSS frequencies, preferred routes, VOR receiver checks and other notices.

Terminal Area Charts (TAC) & Class B Supplements

  • Legends: The TAC legends are located in the same place as Sectional legends in the Documents section of the app in the FAA Catalog.
  • VFR Flyway Planning Chart: VFR Flyway charts display an uncluttered view of the airspace surrounding busy Class B airports, and are printed the back side of TAC charts. These are found in the FAA Catalog in the Documents, under the FLY Charts header.
  • Class B Enhancement Graphics: These display a simplified view of Class B airspace boundaries and altitudes and are located in the FAA Catalog in the Documents.
  • Visual Chart Supplement: These are provided for areas in the US with congested airspace and offer guidance on altitudes and flight paths to navigate through the airspace. Like the other charts mentioned here, these are found in the FAA Catalog in the Documents.

IFR Low & High En Route Charts

  • Legends: The legends for both the high and low altitude IFR en route charts are also located in the ForeFlight Documents in the FAA Catalog, under the Legends header.
ForeFlight alternate minimums

The IFR alternate and takeoff minimums are located in the Airports tab.

Terminal Procedures

  • TPP Supplement: In the traditional book format, the supplement to the Terminal Procedures Publication (TPP) appears at the beginning before all the actual arrival procedures and approach charts. This information is very useful to IFR pilots, and contains explanations of approach charts and circling criteria, approach chart legends and rate of climb/descent tables. The electronic version of this information is located in the Documents section, at the top of the FAA Catalog.
  • Airport Takeoff Minimums and Departure Procedures: The IFR Takeoff Minimums are also normally found in the front of the TPP book, and are used by instrument pilots as a guide when planning a takeoff from an airport when the weather is less than VFR. To access these, go to the Airports tab in ForeFlight, select the Procedures tab, select Departure from the left side options, and you’ll then see an option listed with the airport’s Standard Instrument Departure Procedures called Takeoff Minimums. One thing to point out is that this will load all the Takeoff Minimums and Obstacle Departure Procedures for the region, so you may need to swipe through a few pages to find the ones applicable to your particular airport.
  • Alternate Airport Minimums: The IFR Alternate Airport Minimums are similarly found in the Airports section of ForeFlight. When in the Procedures section of the Airports tab, select Arrival from the list of options at the left, and you’ll then see Alternate Minimums displayed at the top.

A New Option – Map Touch

If you find it a hassle to go to the Documents tab for legends and MOA frequencies, there is another option, and it’s available right on the Maps tab. After selecting a sectional or IFR en route chart to view on the map, tap the Gear (Settings) button at the top of the screen and select Map Touch Action. From here, you can choose one of three options for when you tap on a chart: do nothing, bring the chart to the front of the screen (as the top layer) or bring the chart to the front along with the legends.

ForeFlight chart touch action

Choose this third option and you’ll be able to read all of those marginal notations with just a single tap. This can be confusing for everyday flying, but there are times when this is very convenient. Each time you tap a different chart you’ll see it rise to the top, and its legend will be visible at the left edge of that chart.

This Map Touch feature works for international charts too.

    I don’t find the controlling agency and frequencies for MOAs when using this method. Am I missing something?

    Thanks.

      I just tried it with a MOA. Tap inside the MOA and the Add to Route box pops up. Make sure it’s on All (bottom left) and you should see the info at the top. In my case I see 134.0 – tap to view more.

        I can see the frequency for the Buckeye and Brush Creek MOAs as you describe. However, I don’t see this info when I tap inside the Racer A, B, and C and JPG A, B, C, and D MOAs in southern Indiana. These MOAs prompted my original post.

        Is this because these MOAs are associated with their adjacent restricted areas?

    Is a TRSA a special use airspace? I cannot find the contact frequencies for the Palm Springs TRSA using ForeFlight and the MOA technique discussed above. The airspace will highlight but no additional information comes up. Am I doing something wrong? I know several pilots in the SoCal area that simply do not contact TRSA because frequencies are not handy. (TRSA radio contact is prudent but not mandatory)

    In the Documents section how can I rearrange the items that I have downloaded?

    I would like to put the 2 or 3 that I use near the top and not have to search for it

      Keith,
      Touch the edit button – top left. Now you’ll see Xs in the corner of each document. Place your finger on the doc that you want to move to the top and drag it into position.
