Better Flight Planning Through Automation


The RAP Flight Planning Tool is used to respond to emergency radiological situations. The tool automates the flight planning package process while decreasing Aerial Measuring System response times and decreasing the potential for human error.

DOE Region 3 AMS Flight Planning Tool (FPT)

The FPT is an add-in for ArcMap 10.1. Facilitates planning AMS missions. Output from the FPT is designed to integrate operations of RadAssist, AVID, and Garmin Aviation GPS (696, 796, G-1000). Reports are created and saved to support preflight briefing. AMS Survey Patterns 1. Parallel Lines – Lost Source 2. Deposition – NARAC 3. Road Search – Road and

Stream 4. Custom Search Patterns 5. Navigation Output Could be used to support future regional AMS teams, possibly as a web service.

Example of the flexibility designed into the DOE Region 3 Flight Planning Tool. Displayed to the right are curved parallel lines to demonstrate the capability possible. Literally any search pattern can be created such as expanding circular or expanding rectangular patterns. All flight patterns can be exported to various applications, Garmin Aviation GPS, Garmin GPS.

Geospatial Tools And Aerial Mission

These tools are used to provide accurate geospatial information to the mission pilots for location of airborne surveys and extent of mapping.

Mission briefing maps assure communications are clear between the Health Physicist and Pilot.

Overview map for general information.

Geospatial Tools And Aerial Mission Planning These two maps define the survey area and how the survey will be completed. The survey area shown is between the 60 km and 80 km radial. A parallel line survey is specified with line spacing of 2000 ft, 1000 ft AGL, 70 kn, and 360 NMi of survey lines.

Benefits:

•Preflight briefings have been reduced from 1.5 hours to 15 min.

•Clear communications. Coordinates & headings for the aircraft computer.

•Prevents weather aborted flights by combining flight plan with weather data.

•A second location ( backup plan) can already be selected for monitoring.

•Optimizes and minimizes travel paths.

•Better planning. Better utilization of pilot and aircraft.

•Eliminated training. Tool is intuitively obvious to use.
