ETOLD Pro is a high-precision, offline-resilient cockpit performance and flight briefing coordinator — engineered for low-light cockpits and dynamic operational environments.
Live METAR & TAF
Real-time weather streamsETOLD Pro empowers pilots with immediate access to takeoff performance calculations, enroute meteorology tracking, active aerodrome briefings, and cold-weather corrected descent glidepaths — all from a single web interface with no installation required.
Supplemental Planning Tool: Informational and planning assistance only — not a certified EFB replacement or approved flight operations system.
Pilot-in-Command Authority: All operational decisions remain with the PIC. Information must be independently verified using official references.
Initialize flights with flight number, aircraft tails, departure, destination, and dual alternate coordinates.
Dynamic DOW, ZFW, and TOW with live Souls-On-Board tracking and safety underload alerts.
Real-time METAR and TAF forecasts with data age tracking, wind vectors, and trend analysis.
Collapsible NOTAM boards with FAA NMS-API & AVWX source tracking and active threat isolation.
Watch how ETOLD Pro transforms your pre-flight workflow — from flight setup to dispatch-ready PDF briefing, all in one session.
ETOLD Pro — Full Workflow Demo
Eight precision-engineered modules, purpose-built for professional aviation operations.
Initialize active flights with Flight Number, aircraft tails, departure, destination, dual alternates, and Takeoff Alternate coordinates.
Calculates DOW, payload distribution (Adults/Children/Infants with aviation-standard coefficients), ZFW, and TOW with live SOB tracking and underload alerts.
High-contrast briefing packages with live METAR, TAF trends, and route-wide NOTAM lists. Outputs physical dispatch or PDF on any device.
Complete flights with one click to lock final weights, V-speed records, and archived ATIS letters. Reopen closed logs and export full-fidelity print checklists.
Computes ICAO Doc 8168 altitude corrections for freezing temperatures across progressive DME points from 10 NM down to 0.5 NM.
V-speeds (V1, VR, V2) and Flex Temp with temperature thrust reductions and flap configurations matching strict runway and weight limits.
Global-to-local collapsible structures powered by Zustand with SRC: AVWX / FAA NMS-API badges and retrieval age clocks — no redundant network requests.
Dexie.js (IndexedDB) for local cockpit cache of aircraft models, airport files, METAR, and performance charts. Mutex Sync Locks prevent duplicate records.
A structured, chapter-based workflow designed to match real-world airline dispatch operations.
Login with crew credentials, set a 6-digit glove-friendly PIN, select aircraft fleet and route presets.
Setup active session with FLT, DEP, DEST, ALT identifiers and paste the ATC route string.
Weather & NOTAM review, W&B loading, takeoff performance (RPM), and fuel planning & auditing.
Briefing generation as PBE, flight monitoring via Enroute Console, and CDFA cold-weather correction.
Logbook archiving with locked weights and speeds, then post-flight PDF with PIC signature lines.
Quick-access professional tools always a tap away.
Head/Tail/Crosswind components instantly from any wind input.
Visualize Direct, Parallel, or Teardrop entries with sector mapping.
Hours & Minutes calculator with auto-colon formatting for block times.
Swap between KC/LD5 or Litres/Gallons and aviation units instantly.
Join professional pilots using ETOLD Pro to stay sharp, safe, and in full command — from pre-flight to post-flight archival. Open it right in your browser, no install needed.
