AIP Viewer & Other Charts Query Strings

Required roles: none

Query string parameters open the ibonav.aero AIP Viewer or Other Charts page at a given coverage, section, effective date, aerodrome or document, and can open a chart directly. Both pages need a ibonav.aero member login.

The two pages read separate parameter sets; a parameter of one page has no effect on the other.

Parameters build on each other: each one is optional, and the page is set up as deep as the most specific parameter given. Everything below that level is left to the viewer. A document is opened only when file is given.

AIP Viewer (/aip-viewer)

Parameter Level Value Without it
country 1 Coverage folder, e.g. lt, trnc default coverage
section 2 Section (table below) ad23

icao 4 Aerodrome / data set identifier, e.g. LTBA, LT1401 no aerodrome selected
file 5 Document name without extension, exact, e.g. LTBA - IAC 04 - Instrument Approach Chart file list shown, nothing opened

  • icao is compared, case-insensitively, with the leading letters and digits of the aerodrome folder name (folders look like LTAH - AFY - AFYON - AD or LT1401 - Bolu). Both 4-letter ICAO indicators and other identifiers work.
  • In the non-AIRAC sections (aic, amdt, sup, others) the viewer browses folders; only country and section apply there.
  • For an aerodrome outside the default coverage, give country too (e.g. country=trnc).
# Coverage only

# An aerodrome: its charts are listed, nothing opens

Other Charts (/other-charts)

No AIRAC here: coverage, version and folders only.

Parameter Level Value Without it
country 1 Other Charts coverage folder, e.g. FLIP-CENOR-EB_ED_EH_EK_EN_EP_LK first coverage
version 2 Version folder name, exact, e.g. 2608 - (WEF 06-AUG-2026 TIL 03-SEP-2026) latest effective version (a "(Next)" version is skipped)
airport (or path) 3 Path under the version folder, /-separated. The first part is the Section / Aerodrome / Heliport choice (an aerodrome, or a folder such as a section or category); further parts go deeper. nothing selected
file 4 Document name without extension, exact file list shown, nothing opened 
# A coverage, latest version
https://ibonav.aero/other-charts?country=FLIP-CENOR-EB_ED_EH_EK_EN_EP_LK

# An aerodrome folder in a given version
https://ibonav.aero/other-charts?country=FLIP-CENOR-EB_ED_EH_EK_EN_EP_LK&version=2608%20-%20(WEF%2006-AUG-2026%20TIL%2003-SEP-2026)&airport=EPDE%20-%20DEBLIN

Rules

  • Folder and file names are the ones shown in the viewer (the Charts API returns the same names). Values with spaces must be URL-encoded.
  • A value that matches nothing is ignored; the default of that level applies (for icao, airport and file: nothing is selected or opened). No error is shown.
  • Each parameter is applied once when the page opens; after that the viewer navigates freely.
