Supersonic flight planning, done right.
Concorde EFB is a free, realistic electronic flight bag built for the DC Designs Concorde in Microsoft Flight Simulator — cruise-climb mission profiles, METAR-corrected takeoff and landing performance, interactive checklists, and a live SimConnect flight monitor, all in one desktop app.
What it does
Cruise-Climb Mission Profile
Segmented climb, supersonic acceleration, cruise-climb, and descent modeling for realistic trip fuel and ETE.
Live Performance Calculator
Takeoff and landing V-speeds and runway feasibility, corrected for live METAR wind, QNH, and temperature.
Interactive Checklists
Full cold-and-dark-to-shutdown Concorde checklist flow, synced with live V-speeds once a plan is loaded.
Live Flight Monitor
A glass-cockpit style avionics panel streaming real-time telemetry from MSFS over SimConnect.
Offline Airport Database
39,000+ airports and runways bundled in-app — flight planning works fully offline.
SimBrief Import
Pull route, fuel, callsign, registration, and runway data straight from your SimBrief OFP.
About the project
Concorde EFB started as a small performance calculator and has grown into a full Flutter desktop application — built and maintained in the developer's spare time as a free companion for the flight sim community. It targets Windows, macOS, and Linux, with an optional bundled SimConnect bridge so Flight Monitor works without installing anything extra.
