Sourced
Sourced, not recalled
Every value traces to its controlling FAA table, paragraph, and change note — never a recollection or a stale spreadsheet.
So: the value you ship is the value you can cite.
How It Works
Not a number — a decision.
AvPlot doesn't just return a dimension. Every answer arrives as a full decision you can defend: the Result, the Standard it came from, the Assumptions that drove it, the Logic that derived it, and the Vintage of the source. Sourced, not recalled — on data that's actually current.
THE DECISION OUTPUT
Five questions, answered every time.
Ask AvPlot for an RPZ, and you don't get "1,700 × 500 × 1,010." You get the figure and the four things that make it defensible — the same five fields on every output.
Result
RPZ 1,700 × 500 × 1,010 ft · 29.465 ac (length × inner width × outer width)
Standard
AC 150/5300-13B, Appendix G — Runway Design Standards Matrix.
Assumptions
Approach category C/D, visibility ≥ ¾ statute mile, derived from your runway design code.
Logic
AAC + ADG + approach visibility → Runway Design Code → the controlling RDSM row.
Vintage
AC 150/5300-13B Change 1 (8/2024); airport facts on the current FAA NASR 28-day cycle.
THE PRINCIPLES
Why you can trust the answer.
Newest wins
Newest guidance wins
When two cited FAA sources disagree, the newest release date governs — AC 13B Change 1 over the 2022 figures — and the citation states the dated basis.
So: you're never defending a superseded number.
Fresh data
Data freshness
Airport facts — runway dimensions, declared distances, elevations, headings — come from the FAA NASR 28-day subscription, each row carrying its cycle date.
So: the airport you model is the airport as filed.
THE FLOW
Airport in, defensible output out.
Four steps from a facility identifier to a CAD-ready deliverable.
1
Enter the airport
Type a FAA LID and AvPlot auto-fills runways, declared distances, elevation, and headings from NASR.
2
Select design criteria
Set approach category, design group, and visibility — or set from a critical aircraft.
3
Read the decision
Get the Result with its Standard, Assumptions, Logic, and Vintage — the full citation trail.
4
Export
Drop CAD-ready DXF/KMZ linework or XLSX data tables straight into your design product.
COMPARISON
AvPlot vs traditional methods.
How airfield-geometry work gets done the manual way, and with AvPlot.
| Task | Traditional airport planning | With AvPlot |
|---|---|---|
| Find a dimension | Locate, page, and interpret the controlling AC table by hand. | Returned in seconds with the AC table, paragraph, and change note. |
| Produce linework | Hand-draft in CAD; redo it when an input changes. | Generate CAD-ready DXF/KMZ; regenerate on any input change. |
| Stay current | Track AC changes manually across personal spreadsheets. | AC 150/5300-13B Chg 1 baked in; NASR on a 28-day refresh. |
| Defend a value | Reconstruct the citation trail after the fact. | Citation trail attached to every output by default. |
| Consistency | Varies by analyst and by project. | One engine — identical results firm-wide. |
