What digital (electronic format) products does NACO offer for sale?NACO currently offers the following digital products:
These products may be ordered by contacting the NACO Distribution Division. We are currently developing digital versions of other paper products. Prior to October 1, 2000 NACO was required to forward chart sales proceeds directly to the United States Treasury. Current legislation now allows NACO to retain revenues to provide funding for the development of new products, such as digital charts and publications. Please continue to access the NACO homepage to stay abreast of new aeronautical products and services as they become available. Thank you again for your interest in NACO aeronautical charts and products, and the advancement of air navigation safety. I get an error message when I try to access the Digital-TPP or Sectional Raster Charts Disk?Be certain that your computer has a DVD reader. The amount of storage needed by both D-TPP and SRAC products required NACO to utilize DVD media. How can I get a copy of a digitized chart?The National Geospatial-Intelligence Agency (NGA), formerly the National Imagery and Mapping Agency has developed ARC Digitized Raster Graphics (ADRG) for use with available commercial applications to provide a raster background display of a scanned map image. Most of the following NGA aeronautical chart products are available in ADRG format on CD-ROMs. The FAA has geo-referenced Sectional and Terminal Area Raster Charts now available on DVD.
Please ask for our Free NGA Aeronautical Catalog to see a complete listing of all available digitized charts. Sectional Raster Charts are divided into an Eastern, Western and Alaska Set provided on DVD or can be downloaded through our E-commerce site. ADRGs are not available on a subscription basis. One chart provided per CD-ROM. Can NACO's digital products be use in private industry software products?

The term "charts" is not found in the FAA's Part 91 regulations (other than for large and turbine-powered multiengine airplanes in 91.503[a]). The specific FAA regulation, FAR 91.103 "Preflight Actions," states that each pilot in command shall, before beginning a flight, become familiar with all available information concerning that flight. What is not specifically addressed in the regulation is a requirement for charts. You should always carry a current chart for safety's sake. An expired chart will not show new frequencies or newly constructed obstructions, some of which could be tall enough to be a hazard along your route of flight.
If you, as an FAA Safety Inspector, Designated Pilot Examiner, Flight Instructor, or other aviation professional are telling pilots something other than the foregoing then you are incorrect.
AIM 1-1-19b3(b) Database Currency (1) In many receivers, an up-datable database is used for navigation fixes, airports and instrument procedures. These databases must be maintained to the current update for IFR operations, but no such requirement exists for VFR use. (2) However,...
AIM 1-1-19g Equipment and Database Requirements - For IFR Operations "All approach procedures to be flown must be retrievable from the current airborne navigation database..."
AC 90-100, U.S. TERMINAL AND EN ROUTE AREA NAVIGATION (RNAV) OPERATIONS, paragraph 8a(3): The onboard navigation data must be current and appropriate for the region of intended operation and must include the navigation aids, waypoints, and relevant coded terminal airspace procedures for the departure, arrival, and alternate airfields.
NOTE: Navigation databases are expected to be current for the duration of the flight. If the AIRAC cycle will change during flight, operators and pilots should establish procedures to ensure the accuracy of navigation data, including suitability of navigation facilities used to define the routes and procedures for flight. Traditionally, this has been accomplished by verifying electronic data against paper products. One acceptable means is to compare aeronautical charts (new and old) to verify navigation fixes prior to dispatch. If an amended chart is published for the procedure, the database must not be used to conduct the operation."
Published instrument procedures and routes are incorporated by reference into 14 CFR Part 95 and 14 CFR Part 97, are "law." They are "effective" only during the AIRAC cycle dates specified on the enroute chart/TPP covers or on the side of the chart when printed from the digital-TPP. If you are using a published procedure before or after the dates specified on the chart under IFR, you are technically in violation of the law.
When a navaid is first constructed, the antenna is physically oriented to True North. Then a potentiometer adjustment is made to slave the navaid with Magnetic North. This action matches the isogonic line making it agree with a magnetic compass. Initially these two values are the same, but the magnetic variation of the earth changes at differing rates depending upon location and time. Navaids are commissioned and remain online 24 hours per day 365 days per year. Although periodic maintenance is performed as needed, a re-slaving to match the isogonic value requires a total navaid shut down, re-alignment and a re-certification flight check. Only when the navaid is out of tolerance by at least +/-6 degrees will a re-slaving procedure be initiated allowing the navaid and airport magnetic variation to match again.
Note: GPS databases use a MAGVAR model to calculate the most up-to-date magnetic variation.
Unless specified by the subscriber the new subscription service will begin with the next edition of the product. For example if the next edition date for the Seattle Sectional Chart is June 8th, 2006 and you place your order for a subscription in April you will not receive the current edition (December 22nd, 2005) unless you specify that you want the current edition shipped to you.
All products published by the National Aeronautical Charting Office (NACO) are in the public domain and not copyright protected; therefore, it is perfectly legal to reproduce and publish any of our charts so long as any NACO or FAA logo isn't visible. The reason for this is that the FAA cannot endorse a private industry product or service. No written release or credit is necessary. Since all of our products are date sensitive we recommend that you seek legal advice or stipulate that these charts are not to be used for actual flight navigation in the event that someone decides to use your publication for that purpose.
For purposes of airport depiction, when a runway is between 7970 and 8069 feet in length NACO cartographers round to 8000 which equates to a line 0.192 inches in length on the Sectional chart scale. In this case a circular aerodrome symbol is used. If the runway is between 8070 and 8169 feet in length, cartographers round to 8100 which equates to a line 0.1944 inches in length on the Sectional chart scale. This line is simply too long to fit into the largest circular aerodrome symbol NACO has available. Therefore, when an airport has a runway that is greater than 8069 feet in length cartographers place a box around the runway pattern forming an enclosed shape.
The National Aeronautical Charting Office (NACO) cannot arbitrarily depict airspace on its charts without proper authorization. Certain procedures must be followed before NACO may chart any aeronautical information, especially airspace. Please consult FAA Order 7400.2F, Procedures for Handing Airspace Matters, http://www.faa.gov/airports_airtraffic/air_traffic/publications/at_orders/media/AIR.pdf.
You must have a place of business which is open to the general public for over-the-counter sales. You must do a net dollar volume of $500.00 per year. Agents will be permitted one year to establish their business. Thereafter an agent not selling a volume sufficient to maintain an active status may be discontinued. You will receive a 40% discount on all of our products. You will have complete return privileges for obsolete charts and publications for full credit to your account. You are expected to maintain a less than 20% return rate of your ordered products. Agents with excessive returns will be considered for cancellation. You do not have to prepay orders - they will be billed by invoice. A monthly statement will be generated on the last business day of the month and then mailed to the agent. The monthly statement will list all transactions made during that period. If you are interested in becoming an authorized chart agent, please mail or fax the FAA Distribution Division your name, address and telephone number so we can send you the appropriate Chart Agent agreements and instructions. Please specify whether you are interested in becoming an aeronautical or nautical chart agent.

Airports with at least 1,500 feet of hard surface runway will be depicted on our visual charts. Airports with 3,000 feet of hard surface runway will be depicted on our enroute charts. If your airport meets those criteria and you would like your airport charted you should contact the local Federal Aviation Administration, Airports District Office or Aeronautical Information Services, ATA-100, at 1-866-295-8236. The FAA Specialist will verify your airport information and publish a change in the National Flight Data Digest. This change will generate a charting directive to depict your airport on the chart. NACO will chart your airport if it does not interfere with any existing chart data that may have a higher safety priority and or cause chart clutter. Every effort will be made to move chart data around and accommodate your airport name and symbol depiction on the chart for the next publication cycle.

Parachute jump areas are designated airspace areas that are depicted to alert the flying public of special air traffic activity. Charting these areas may be accomplished by contacting the FAA Regional Office having jurisdiction over the airspace and request the specific area be charted. The FAA Specialist will verify the information, apply the data to standard charting criteria:
Jump sites can also be nominated by FAA Regions if special circumstances require charting.
Once published in the National Flight Data Digest, the information will be added to the PARACHUTE JUMPING AREAS Section of the Airport/Facility Directory. If the parachute jump area meets minimum charting requirements we will depict the Parachute Jump Area symbol on the appropriate chart for the next publication cycle.
Glider areas are designated airspace areas that are depicted to alert the flying public of special air traffic activity. Charting these areas may be accomplished by contacting the local Flight Service Station, or Aeronautical Information Services, ATA-100, at 1-866-295-8236 and request that the specific area be charted. The FAA Specialist will verify your information, apply the data to standard charting criteria, and publish the information in the National Flight Data Digest if it meets all the requirements. Once published the glider symbol will be added to the appropriate chart for the next publication cycle.
UNICOM and CTAF frequencies are important communications frequencies at all airports authorized to use them. To add, modify or delete frequencies, airport owners/managers should contact the local Flight Service Station, or Aeronautical Information Services, ATA-100, at 1-866-295-8236 and request your authorized UNICOM or CTAF frequency be published and/or charted. The FAA Specialist will verify your information and publish a change in the National Flight Data Digest. Once published the information will be depicted in the appropriate publications and/or sectional charts for the next publication. The following form may be used to submit changes: A-FD Revision Form.
