Background: Technology NAV enhancements GPS
Electronic Flight Bags (EFB) Terrain Awareness and Warning System (TAWS)
Improved ATC RADAR coverageSlide6
NTSB Case Study: Accident Number: IAD05MA006 Beechcraft
King Air 200, N501RH
NTSB Probable Cause: …“Contributing cause of accident was flight crew’s failure to use all available navigational aids to monitor the aircrafts position along the procedure.”

NTSB Case Study:Controlled Flight into Terrain (CFIT):
“Controlled flight of airworthy aircraft unintentionally into terrain without awareness”Slide8
Project Objectives and Goals: Improve IAP situational awareness with addition of shaded terrain
Predefine terrain intervals
Clip terrain to extent of
planview Python foundational codingSlide9
Proposed Methodology: 3 functions
Terrain python script
GeoPDF to GeoTIFF python script Incorporation of GDAL open source raster/vector translation library
Planview clip
All scripts to be loaded as ESRI add-ins
Terrain and
planview
extents stored in personal
geodatabaseSlide10
Terrain Python Script Process:
Mosaic
Focal
Statistics
Meters to
Feet Conversion
Reclassify
Contour Generation
Raster to Polygon

Terrain Python Script Process: Ensure aligned projection and datum.
Elevation reclassifications embedded within script for 1000’ intervals
Discard intermediate data
Field calculations maintain finalized terrain sets based on airport identifiersSlide12
Raster Import Tool:
IAP
