Legacy Instrument Approach Procedure (IAP) :
Minima
Planview
Profile
– Complete IAP extent
– Altitude stepdowns
– Defined minimum descent heights
Navigate and land in adverse weather conditions
Human factors study

Volpe Instrument Approach Procedure (IAP) :
Minima
Planview
Profile
– Complete IAP extent
– Altitude stepdowns
– Defined minimum descent heights
Pilot Briefing Bar – Notes/Comm
Organizes information into logical flow
Less time searching… more time flying

Background: Technology NAV enhancements
GPS Electronic Flight Bags (EFB) Terrain Awareness and Warning System
(TAWS) Improved ATC RADAR coverage

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”

Project Objectives and Goals: Improve IAP situational awareness
with addition of shaded terrain
Predefine terrain intervals
Clip terrain to extent of planview
Python foundational coding
![Page 9: Improving Situational Awareness on Instrument Approach Procedures:](https://reader036.vdocuments.mx/reader036/viewer/2022062322/568148bb550346895db5d7ae/html5/thumbnails/9.jpg)
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 geodatabase

Terrain Python Script Process:
MosaicFocal
Statistics
Meters to Feet
Conversion
Reclassify
Contour Generation
Raster to Polygon
Add/ Calculate
Field
Final Raster
Final Raster

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 identifiers

Raster Import Tool:
IAP
RasterTranslator
PythonBindings
TerraGo functions costly Required for Adobe Required for ArcMap
Open Source translator works well with numerous languages
GeoTIFF
