Welcome to our Terms and Definitions Feedback Form!

Just as with every other publisher of rapidly evolving, complex content, occasionally there are things that we can improve upon. Sometimes the reasons for this are technical and sometimes they're not. What makes our materials and system unique is that, thanks to this direct link to our editorial team which you are now using, we can rapidly consider and incorporate your feedback. We hope that you can appreciate that we have this system in place not because our stuff is shoddy, but, rather, because it is good.

We gladly and sincerely welcome constructive, considered, and, where possible, cross-referenced feedback on specific items of content using the form below.

This is not the place for technical or customer support requests! We'll be happy to hear from you on such issues via our Online Helpdesk. Please use this form only to provide feedback relating specifically to one very particular piece of content (such as a single term/definition) as your message here will go to our editorial team only, not our technical or customer support staff. You will not receive a timely response (and in fact might get none at all) if you submit such a message through this system instead of via our helpdesk.
Please make sure your app/program content is up to date before using this feature - A very high percentage of false reports we get via this system can be traced to the fact that the user does not have the latest version of the program content on his/her device. Please be 100% sure (especially if you are thinking about submitting a ticket about a "missing image") that before submitting a ticket here that you have used the in-app or in-program update utility for the program or app in question (often available via a 'get updates' or 'check for updates' link or button from the main menu). This will also help ensure that you are studying the latest and greatest material!

Here is the current term: If below it different substantially compared to how it appears in your app/software, be sure to update your software/app's content prior to using this form.

SECTIONAL AERONAUTICAL CHART

A map used in air navigation containing all or part of the following: topographic features, hazards and obstructions, navigation aids, navigation routes, designated airspace, and airports. Commonly used aeronautical charts are:

Sectional Aeronautical Charts (1:500,000)- Designed for visual navigation of slow or medium speed aircraft. Topographic information on these charts features the portrayal of relief and a judicious selection of visual check points for VFR flight. Aeronautical information includes visual and radio aids to navigation, airports, controlled airspace, restricted areas, obstructions, and related data.
VFR Terminal Area Charts (1:250,000)- Depict Class B airspace which provides for the control or segregation of all the aircraft within Class B airspace. The chart depicts topographic information and aeronautical information which includes visual and radio aids to navigation, airports, controlled airspace, restricted areas, obstructions, and related data.
World Aeronautical Charts (WAC) (1:1,000,000)- Provide a standard series of aeronautical charts covering land areas of the world at a size and scale convenient for navigation by moderate speed aircraft. Topographic information includes cities and towns, principal roads, railroads, distinctive landmarks, drainage, and relief. Aeronautical information includes visual and radio aids to navigation, airports, airways, restricted areas, obstructions, and other pertinent data.
En Route Low Altitude Charts- Provide aeronautical information for en route instrument navigation (IFR) in the low altitude stratum. Information includes the portrayal of airways, limits of controlled airspace, position identification and frequencies of radio aids, selected airports, minimum en route and minimum obstruction clearance altitudes, airway distances, reporting points, restricted areas, and related data. Area charts, which are a part of this series, furnish terminal data at a larger scale in congested areas.
En Route High Altitude Charts- Provide aeronautical information for en route instrument navigation (IFR) in the high altitude stratum. Information includes the portrayal of jet routes, identification and frequencies of radio aids, selected airports, distances, time zones, special use airspace, and related information.
Instrument Approach Procedures (IAP) Charts- Portray the aeronautical data which is required to execute an instrument approach to an airport. These charts depict the procedures, including all related data, and the airport diagram. Each procedure is designated for use with a specific type of electronic navigation system including NDB, TACAN, VOR, ILS RNAV and GLS. These charts are identified by the type of navigational aid(s)/equipment required to provide final approach guidance.
Instrument Departure Procedure (DP) Charts- Designed to expedite clearance delivery and to facilitate transition between takeoff and en route operations. Each DP is presented as a separate chart and may serve a single airport or more than one airport in a given geographical location.
Standard Terminal Arrival (STAR) Charts- Designed to expedite air traffic control arrival procedures and to facilitate transition between en route and instrument approach operations. Each STAR procedure is presented as a separate chart and may serve a single airport or more than one airport in a given geographical location.
Airport Taxi Charts- Designed to expedite the efficient and safe flow of ground traffic at an airport. These charts are identified by the official airport name; e.g., Ronald Reagan Washington National Airport. (See AERONAUTICAL CHART.)

Please do not use this form to tell us that the definition you saw doesn't necessarily match the context where you saw it. We use an automated keyword-based system to match the tens of thousands of definitions in our glossaries with our material. Sometimes, when a term has more than one meaning or use or when an abbreviation might stand for more than one thing or resemble a 'normal' word, this results in a definition for a term being shown that doesn't necessarily match the context. Please do not report such issues here. Rather, please use your best judgment to evaluate whether such definitions apply to what you're reading. If the answer is 'no' but nevertheless you feel the term doen't have a good definition in our system but should, please go back and find the 'suggest a term' link in the app. Thanks!

We welcome your feedback. Please carefully fill out the specifics below. If you wish to comment on more than one term/definition, please fill out and submit this form separately for each.
