Nimble Preflight

The professional pilot’s companion.

Weather, NOTAMs, hazards, route briefing and flight watch — in one fast, cockpit-dark app. Designed by an active airline captain, built on official sources, and engineered to keep working when the signal doesn’t.

Every screen

One tab for every question a crew asks.

Weather, notices, hazards, charts, tracking and the calculators — each built for one job, all in one fast, offline-capable app that sits beside your official briefing, never replacing it.

The app

One place for the whole pre-flight picture.

Weather, NOTAMs, advisories, charts, flight tracking and a full set of pilot calculators, gathered into a single fast app. The one you open in the crew room, on the bus, at the gate — everything a tap or two away, and most of it still working when the signal doesn’t.

Airports Watchlist grouped by country with raw METAR, TAF and NOTAM counts

Watchlist

Your airports, at a glance.

Up to a hundred stations, grouped by country. Each card shows the raw METAR, raw TAF and active NOTAM count without you opening anything — with an honest data-age indicator on top, so you always know how old the picture is.

Live hazard map

Your route, your watchlist, and every hazard between them.

Great-circle track with embedded thunderstorm and icing zones, jet-stream cores and forecast timeline — scrub it to see what’s active at departure, en route, or on arrival.

Weather + imagery, one timeline

SIGMET polygons over the live DWD satellite layer — scrub hazards and cloud together.

WATCHMAP · DWD + NOAA · SITUATIONAL AWARENESS ONLY

Watchmap · Layers in Context

One picture. Multiple operational layers.

Route, advisories, icing, turbulence and weather context remain readable together — with authentic source data and the real Watchmap controls kept visible.

Structured atmospheric scene with Nimble Watchmap product context

Atmospheric Intelligence

Weather has shape.

Atmosphere becomes readable structure: flow, boundary and scale. The visual language echoes Watchmap without pretending that brand imagery is operational data.

Airport

One field, top to bottom.

Tap any card and land on one long scroll, always in the same order — a METAR trail with the newest tagged LATEST, the raw TAF, and a runway wind analysis. A speaker button reads the report aloud. Your eye learns the layout once and never hunts again.

Freshness is visible.

Raw METAR. Raw TAF. Runway-wind geometry. Source timestamps that let the pilot judge the age of what is on screen. When cached or older data is being shown, the product is designed to make that state explicit rather than silently present it as current.

Operational depth

Go deeper when the picture needs it.

Aerodrome and FIR notices — exactly as issued.

Split the way your briefing is: what affects the aerodrome, and what affects the airspace you’ll cross. Straight from the FAA Notice to Air Missions System and shown byte-for-byte — never reworded, never summarised.

Airport NOTAM screen with amber NOTAM chips

Five families, five colours.

SIGMET, AIRMET, GAMET, volcanic ash and tropical cyclone — each family keeps one colour everywhere, on the chips, the cards and the map polygons. Filter to what matters, then view any hazard in its geographic context.

Advisory detail screen

Observations, not forecasts.

AIREPs and PIREPs from crews actually in the conditions they describe. A chart tells you where turbulence is expected; a pilot report tells you an aircraft got it — at a time, a level and a position. The screen you check when forecast and reality might be diverging.

WX Charts

Five charts, five jobs.

Not variations on one picture — each tab answers a different question, and knowing which one to reach for is most of the skill.

Explore weather charts
SIGWX significant weather chart
TAB 1SIGWX — the classic significant weather chart.The WAFS high-level significant weather chart, covering FL250 to FL630 — the sheet every long-haul briefing pack contains. Jet streams, CB areas, turbulence boxes and tropopause heights, in a pinch-and-zoom chart viewer.
Wind and temperature chart with barbs at flight level
TAB 2WIND / TEMP — upper winds at your level.Wind barbs and temperatures for the selected region and flight level — the answer to “what should I expect at FL350?” before you ever read the OFP.
ECMWF precipitation forecast animation with timeline scrubber
TAB 3ECMWF RAIN — two days of precipitation, animated.A precipitation-rate forecast from the ECMWF model, animated from now to T+48. Play it, drag the scrubber frame by frame, change speed — 0.5×, 1×, 2×, 4× — with the valid Zulu time on every frame and a SYNCED chip that tells you exactly how fresh the data is.
Global infrared satellite mosaic with colourised cloud tops
TAB 4SATELLITE — the global infrared loop.Colourised cloud-top temperature, worldwide, animated over recent frames on a pannable, zoomable basemap. Colder tops mean higher tops — you read it like a pilot, with the official DWD legend one tap away.
IWXXM SIGWX tab showing vector significant weather layers with phenomenon pills and timeline
TAB 5IWXXM SIGWX — significant weather as switchable layers.The modern counterpart to the PNG chart: the same WAFS significant weather rendered as vector layers on an interactive map — CB, icing, turbulence, jet streams and tropopause, each a switchable pill, steppable from T+06 to T+48.

Human Life · Night Before

The night before counts too.

Preparation is not one place or one lighting condition. Nimble belongs in the quiet moments before duty as naturally as it does in the crew room or at the gate.

Brief

One route, five views, one pack.

Give it a departure, a destination and your alternates — Brief pulls the whole picture together into a single pack you can save and reuse.

Human Life · Between Sectors

Rebuild context between sectors.

A short, calm check in the middle of the working day — the moment the next picture has to come back together.

Flight Watch

One aircraft, followed properly.

Not a radar screen, not a fleet display — Flight Watch follows the one aircraft you actually need to know about: the inbound you’re taking over, the positioning flight that decides when your duty starts, the aircraft carrying your crew, a family arrival.

Flight tracking is for situational awareness only and can be delayed, incomplete or unavailable depending on coverage and source availability.

Lock-screen push notification showing flight number, percentage complete, route and remaining time

Push notifications

Progress on your lock screen.

Flight and percentage in the title, route and remaining time in the body — updated every minute, no need to reopen the app. And Flight Watch is the only feature that can send you a notification. Nothing else — not weather, not NOTAMs, not advisories — will ever interrupt you. While driving to the airport, you might just have time to grab a coffee on the way.

Dual-source resilience

Two independent weather authorities, with automatic failover. When one source went dark in a real NOAA outage, the app kept briefing — because it already had a second.

Pilot toolkit

Eleven calculators, one colour language.

The numbers you’d otherwise run on a phone calculator or the back of a jepp chart — each answering one question a line pilot actually asks, results saved straight to your repository.

TOOL 01

Limitation of the Day

“What’s my maximum take-off weight today, and what traffic load does that leave?” Build the operating weight, enter the limits, and read what the day allows — four candidate limits compared, the lowest in red.

TOOL 02

Fuel Tankering

“How much extra fuel can I legally carry, and how much do I need for two sectors?” The limit in red, the usable fuel in green.

TOOL 03

Fuel Uplift

“Does the metered volume match the fuel I actually needed?” Mass first, then volume, then the discrepancy — in both units.

TOOL 04

ACN / PCN

“Can this pavement take my aircraft at weight?” The verdict, the interpolation ratio, and any required offload.

TOOL 05

Cold Temp Correction

“What altitudes should I fly on approach in this cold?” Five fixes corrected per ICAO Doc 8168, each delta in amber, with the approach profile drawn underneath — a mistyped altitude shows up as a kink.

TOOL 06

Wind Component

“What are my headwind and crosswind components?” Head or tail, crosswind, and the gust pair — with the trigonometry printed on screen and a runway diagram underneath.

TOOL 07

SNOWTAM Decoder

“What does this winter message actually say?” Paste it and read it back per runway, per third — RWYCC, contaminant, coverage and depth — plus snow banks, taxiways and aprons.

TOOL 08

Timing

“What do all these times add up to?” A running tape, the total in HH:MM and in decimal hours.

TOOL 09

Unit Converter

“What’s that in the other unit?” Twelve aviation conversions in a grid — pick one, type, read the result in green. 1 NM = 1852 m exact, ref ICAO Annex 5.

TOOL 10

Decibel Meter

“How loud is it in here?” Live dB SPL, session peak and an exposure word — approximate, uncalibrated, and the app says so in the strongest terms it uses anywhere.

TOOL 11

Delay Allocation

“So what actually held us?” Give it the block times for one turnaround and the events that happened during it; it works out, minute by minute, where the delay went — and hands you a plain-text report you can copy. A personal aide-mémoire, never an official one.

Calculators and references are support tools only. Company procedures, approved performance sources and operational requirements remain authoritative.
