APRA provides the private sector greater access to core FAA data to spur more innovation in the aviation industry, and ultimately advance the FAA's mission of safety in flight. Based on stakeholder recommendations, this initiative's first effort strived to provide both more data and better data for Aeronautical products and information. Solution Delivery developed and deployed web services for several aeronautical products including both information about those products and the ability to automatically download those products which satisfied one of the recommendations.
APRA provides a mechanism for a client program to scan the FAA public web site for a specific type of aeronautic product for download. The aeronautic products available include charts in various formats. Such charts are often released to the public on either a 28 day or 56 day airspace cycle. Upon release of charts, the URL(s) for the chart retrieval necessarily change. APRA constructs the standard URL where the chart may be downloaded to enable a software application to pull the charts without the need for a human interface or web based GUI.
