VATSIM & IVAO · Electronic Flight Bag

Airline-grade A320 performance. VATSIM-native briefing.

Import your SimBrief OFP and SkyNexus builds the full briefing — FCOM-grounded A320 takeoff and landing performance, a predicted runway-vacate exit, route-aware weather, charts, and live VATSIM and IVAO ATC matched to your routing by airspace geometry. The depth the in-sim EFB can’t reach, free in any browser alongside MSFS 2024, X-Plane or P3D. No install.

Features

The depth a free EFB isn’t supposed to have

Two things no in-sim EFB and no free competitor ship together: real FCOM-grounded A320 dispatch math and an eWAS-style route forecast. Then every source that matters — weather, NOTAMs, division notes, airport data and live VATSIM & IVAO ATC — reconciled into a flight-ready briefing. You read decisions, not raw data.

A320 performance calculator inside SkyNexus EFB showing V-speeds, runway distances, flex temp and a runway profile diagram
New

The most advanced A320 performance calculator in Flight Simulator

  • V-speeds
  • Flex temp
  • OPTIMUM flap
  • Wet / contam
  • CG → trim

Real dispatch math, integrated with your SimBrief OFP and the live METAR. V-speeds, three runway distances, flex temp, OPTIMUM flap, autobrake, reverse, MEL items, wet and contaminated models and a CG → trim derivation — every number explained by a help modal, every step auditable from public Airbus material and the open-source OpenAP library. Free, where this normally sits behind a paywall.

Route-aware eWAS-style weather forecast in SkyNexus EFB — jet stream, turbulence and icing polygons over a planned route with the vertical cross-section open
New

The first eWAS-style weather forecast for flight sim

  • Turbulence
  • Icing
  • Jet stream
  • Fronts
  • T+36h hourly

Turbulence, icing, jet streams and fronts overlaid on the enroute map at your selected flight level, plus an interactive vertical cross-section along your route. NOAA GFS, scrubbable hour-by-hour to T+36h — no SimBrief Premium tier required.

And the full briefing underneath

Flight Plan, Parsed & Enriched

Import your SimBrief OFP and we reconcile weights, fuel, routing, cruise level and alternates into a single briefing. Alternates get their own full tab — no manual copy-paste from the PDF.

Airport Info, Consolidated

Runways, NADPs, engine-out SIDs, ATIS letters, taxi briefings, airport ops notes and 100+ VATSIM division briefings (UK, Germany, Scandinavia, Austria, Poland, Spain, Italy, Belux, Portugal, Netherlands) formatted into one readable page per field.

Charts, Flight-Aware

Link ChartFox (free) and the aerodrome, SID, STAR and approach plates for your filed runways and procedures are picked out, pinned and ready in an inline PDF viewer with zoom, pan, rotation and pinch.

Weather, Already Interpreted

METAR and TAF parsed into wind components, crosswind, visibility and ceiling per runway. A live enroute weather map threads wind barbs, conditions overlay and strong-winds highlighting along your route.

Threats, Auto-Assessed

We cross-check weather, NOTAMs and division notes against your runway and flight phase, then surface the critical items as a threat banner — not buried three scrolls down.

Live VATSIM & IVAO, Matched by Geometry

VATSIM-native, not a network bolt-on. The coverage strip matches controllers, ATIS and FIR sectors to your actual routing by airspace geometry — not a nearest-airport guess — on both VATSIM and IVAO. Expand it for every station's frequency and handoff waypoint, and get a global popover the moment your COM1 is tuned to the wrong station for your position.

Why SkyNexus

“Free, browser-based, VATSIM-aware” isn’t the differentiator anymore

Half a dozen sim EFBs now claim some version of that. So here is the line that actually matters: SkyNexus is built around operational depth no in-sim EFB and no free competitor ships — and the things below are genuinely hard to fake.

Real dispatch math, not a lookup table

FCOM-grounded A320 takeoff and landing performance — V-speeds, three runway distances, flex, OPTIMUM flap, wet and contaminated models, MEL items, CG → trim — derived from public Airbus material and OpenAP, every number auditable in a help modal.

The in-sim perf is a toy; paid tools paywall the tables.

VATSIM-native, not a network bolt-on

Controllers, ATIS and FIR sectors matched to your actual routing by airspace geometry — on both VATSIM and IVAO — plus a global alert the moment your COM1 is wrong for your position.

Others list the nearest controllers and call it VATSIM support.

It tells you which exit you'll make

A predicted runway-vacate exit from your SimBrief landing weight, the live METAR wind and the runway geometry — on the briefing tab, before you start the approach brief.

No in-sim EFB and no competitor ships this today.

Zero install, independent, genuinely free

One URL in any browser, alongside MSFS 2024, X-Plane or P3D. No community folder, no app-store version mismatch, no Navigraph subscription on top. Indie and EU-built — not owned by private equity.

No download, no panel conflicts, no recurring bill.

SkyNexus EFB Briefing Panel
Briefing

Briefing Panel

Complete flight overview with weights, fuel, timing, departure and arrival weather, routing, alternates, and cruise level impact. A live VATSIM coverage strip sits at the top so you see the ATC picture for your route — controller by controller — without leaving the page.

SkyNexus EFB Runway Exit Prediction
Runway exit

Runway Exit Prediction

A predicted runway-vacate exit for every runway at your destination and alternate — from your SimBrief landing weight, the live METAR wind and the runway geometry, with three deceleration profiles. You brief the taxi route before the flare, not after. No in-sim EFB and no competitor ships this.
