Airports

FlightLog includes a downloadable airport database used to enrich your flight entries with coordinates, timezone, city name, distance, and night-time flags.

Downloading the Database#

On first use (or after clearing the database), you are prompted to download airport data. Two options are available:

A progress indicator is displayed during the download.

AIRAC Cycle Updates#

Airport and landing performance data follows the AIRAC cycle (Aeronautical Information Regulation And Control) – a standardized 28-day update cycle used worldwide for aeronautical data.

FlightLog automatically detects when a new AIRAC cycle is available:

• On app launch, the Dashboard checks your installed AIRAC cycle against the current one
• If outdated, a notification prompts you to update from the Airports page
• Landing performance and approach data are also refreshed automatically based on the AIRAC cycle
• Approach data includes runway approach types (ILS, RNP, VOR, etc.), decision altitudes, visibility minima, medical and security status – used by ENROUTE and the airport sketch
• Approach data (approaches.json) is force-refreshed when the airport database is updated to a new AIRAC cycle
• The current AIRAC cycle is displayed below the runway sketch on each airport detail page

Searching Airports#

Use the search bar to find airports by:

• ICAO code (e.g. LFPG)
• IATA code (e.g. CDG)
• Airport name (e.g. Charles de Gaulle)

Airport Cards#

Each airport entry in the search results displays:

• ICAO code
• IATA badge
• Full name
• Municipality displayed below the airport name
• Airport type – shown as a badge (e.g. MEDIUM AIRPORT, LARGE AIRPORT). Closed airports display a CLOSED chip
• Coordinates (latitude / longitude)
• UTC offset (DST-aware – see below)
• Warning icon (orange) when a warning note exists for that airport

Tap an airport card to open its detail page.

Airport Detail#

The detail page provides full information about an airport:

Identity and Location#

• ICAO and IATA codes
• Airport name and city
• Coordinates (latitude / longitude)
• UTC offset (editable – tap to modify)
• Timezone

DST-Aware UTC Offset#

The UTC offset displayed for each airport is computed dynamically based on the airport's timezone name and the current date. This means the offset automatically reflects Daylight Saving Time:

• Paris (Europe/Paris): UTC+1 in winter, UTC+2 in summer
• New York (America/New_York): UTC-5 in winter, UTC-4 in summer
• Airports without DST (e.g. Abidjan): always show the fixed offset

This DST-aware offset is also used when computing flight data such as FDP limits, latest departure/arrival times, and local reference times.

Runway Sketch#

An oriented diagram of the runways with identifiers, length, width and painted markings (aiming point, touchdown zone). A MSA symbol is shown when available.

Airport Plan PRO#

Detailed plan with taxiways, stands (black on yellow), gates (white on grey, shown when zoomed in), holding points and PAPI. Taxiways and stands closed by NOTAM are drawn on the plan (closed stands: red cross, number in white on red).

• EXIT DIST. – distance from the threshold to each runway exit, for the selected runway.
• TDZ – touchdown zone of runways whose markings are known.

Taxi Guidance PRO#

Open the plan from the DEP or ARR button of a flight (it uses the flight's RWY and STAND fields):

• Departure – route from the stand to the runway entry.
• Arrival – route from the runway exit to the stand.

Follow-the-greens lights show the route, with taxi distance and time at 10 kt. Runway crossings pulse in red. Taxiways closed by NOTAM are avoided.

Long press on a runway exit or entry to change it (also on another runway), or on a stand to change the flight's stand.

Performances PRO#

On arrival, enter your computed landing distance (LDR) for the runway. FlightLog shows the latest touchdown point with no margin and the landing distance; with the TDZ layer on, both are drawn on the plan. Always aim to land in the touchdown zone.

Weather & NOTAMs PRO#

METAR, TAF and NOTAMs of the airport.

• Opened from a flight, they load at once and are applied to the plan at the flight's time (OUT or IN, ±30 min), schedules included. Opened on its own, every NOTAM counts.
• Each NOTAM shows its schedule (item D).
• Tap a NOTAM for its activity timeline: the flight's OUT / IN ±3 h, or the next 24 h without a flight. Active periods are drawn as bars; SCHED marks a NOTAM with a schedule, SCHED ? one whose schedule could not be read.
• NOTAMs not active in that window are greyed and listed last.

Rapid Exit Distances (RET) PRO#

When landing performance data is available, the detail page displays a table grouped by runway showing:

• LDA (Landing Distance Available) as a highlighted badge. LDA uses a cascade resolution: LDG_PERFS data first, then approaches.json, then rwy_data as fallback
• Each rapid exit taxiway with its THR to RET distance and a visual progress bar

Landing performance data (LDG_PERFS) is automatically downloaded and cached based on the AIRAC cycle.

AIRAC Cycle Management#

The current AIRAC cycle is displayed on each airport detail page. When a new cycle is available, FlightLog prompts you to update. Updating refreshes airport data, landing performance data, and approach data simultaneously.

Performance Files per Cycle#

Three performance files are managed per AIRAC cycle: LDG_PERFS (landing performance), approaches (approach types and minima), and waypoints (FPR route data). These files are automatically downloaded during airport database updates (REGULAR or COMPLETE), with progress messages displayed for each file.

The Dashboard notification for a new AIRAC cycle only appears when all three files for the new cycle are available on the server, ensuring a complete dataset before prompting an update.

Warning Notes#

Add custom notes or warnings for any airport. These are synced with your logbook data and displayed as an orange icon in the search results.

Clearing the Database#

You can delete the airport database from the airport screen and re-download it at any time – for example, to switch between REGULAR and COMPLETE datasets or to get the latest AIRAC cycle.
