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
Human factors study
Technology navigational enhancements: Terrain Awareness and Warning
System (TAWS) Electronic Flight Bags (EFB) FMS/GPS Improved ATC RADAR coverage
A
B @ 4000’
C @ 4000’
D @ 2600’
E @ 1400’305°
Tool Objectives Improve IAP situational awareness Minimize interactions
User defines extent ICAO Code and IAP name
Let Python do the work… Transform/import IAP Clip elevation data Mathematically calculate intervals Manage permanent/intermediate data

IAP GeoPDF to GeoTIFF Import:
IAP
RasterTranslator
PythonSubprocess
TerraGo functions costly Required for Adobe Required for ArcMap
Open Source translator works well with numerous languages
GeoTIFF
Transforming with GDAL
Importing into MXD

Global combobox work around
Assembly of points into array
Closes polygon via double click of mouse
1st single click
Double click!!
5th single click
4th single click
2nd single click
3rd single click
Mosaic Dataset/Planview Extents
Terrain Polygon
Mathematical Reclassification Remap
Field Calculations
Clipping
Symbolize with standard layer properties Export map to PDF
BEFORE AFTER
IAP Terrain Editor Quickly update revised IAPs
Re-import procedure Pre-populated combo boxes Retrieves stored terrain
Future Enhancements: Consumption within electronic flight bags
Managed within web service User accounts Independent of unique software
Topographical additions: Transportation Populated Areas Landcover
Summary:Performance based navigation will skirt
the landscapePersonalizes navigational situational
awareness Alternative to expensive avionic systems
