Fulcrum · Weight & Balance

From load control to a signed loadsheet, in one screen.

Web-based weight and balance for load control and dispatch — built on your operator's certified database, closing out with a live CG envelope and an LDM.

The workflow

Six steps, in the order load control actually works.

Flight, configuration, fuel, passengers, cargo, output. Nothing hidden behind a menu, nothing that has to be re-entered downstream.

MAIN

Flight

Flight identity, route and the running summary of configuration, fuel, passengers and cargo as they are entered.

CONF

Configuration

Crew complement, pantry and flight kit resolved into DOW and DOI, with MTOW and MLW editable for the day's dispatch.

FUEL

Fuel

Procedure and density, taxi, takeoff and trip fuel, block and maximum — indexed wing-first then centre tank, with the arm interpolated from the aircraft's own fuel table.

PAX

Passengers

Destinations against categories, zone by zone, with the operator's weight policy applied and a remaining-seat counter.

CARGO

Cargo

Holds against baggage, cargo and mail, split by destination, with per-hold maxima enforced as you load.

OUTPUT

Loadsheet

The Load Distribution Message, ready to transmit — with every intermediate figure traceable back to the tab it came from.

CG envelope

The limit, drawn — not described.

Your certified forward and aft limits as the boundary, and the aircraft's actual state plotted inside it.

  • ZFW, TOW and LDW as points, and the fuel burn as a vector running from zero-fuel to takeoff weight.
  • %MAC and index on the same chart — diagonal %MAC lines above, index scale below, weight up the side.
  • MTOW, MLW and MZFW marked where they bite.
  • Out-of-envelope and over-limit states flagged with the reason, not a generic warning.

LDM output

The arithmetic

Real index maths, from your database.

  • DOW and DOI derived from the actual crew configuration plus pantry and flight-kit corrections — not a single stored operating weight.
  • Passenger index by zone centroid and weighted average category, rather than a flat per-head figure.
  • Fuel index interpolated from the aircraft's fuel table, wing tanks filling before centre.
  • Underload with its limiting factor — which of ZFW, TOW or LDW is the one actually holding you.
  • Trim computed per weight and flap setting from the certified trim formulas.

Fleet and data

Your aircraft, your certified numbers.

Per-operator databases

Envelopes, cabin zones, cargo holds, crew corrections, fuel tables, weight categories and trim formulas all come from your operator's certified weight & balance database — delivered and revised per company, never shared between them.

Two manufacturers, one session

Boeing and Bombardier fleets available side by side from separate certified databases, so a mixed operation works from a single screen.

AHM 560

IATA AHM 560 loadsheet handling as a companion service, for operations that exchange load data in the standard message format.

The same database flies. Load control on the web and the weight & balance module inside eLila EFB read the same certified source. The figures the loadmaster produces and the figures the captain signs cannot drift apart, because there is only one of them.

Send us a loadsheet you already trust.

We will reproduce it in Fulcrum against your envelope and show you the two side by side — the fastest way to see whether the maths matches your operation.
