Weight & Balance

Load control on live check-in data

Calculate ZFW, TOW, and LDW against the certified envelope, auto-balance compartments, and issue an AHM-compliant loadsheet - synced with departure control in real time.

How load control gets done without a system

Spreadsheets, paper trim charts, and standalone tools that never see live passenger data.

Spreadsheet trim sheets

Load controllers maintain per-aircraft Excel files. One wrong cell reference and the CG math is off - nobody catches it until the check fails.

Stale passenger data

Standalone load control tools work from PNL snapshots. Late check-ins, gate upgrades, and offloads mean re-keying counts minutes before close-out.

Manual index math

DOW, DOI, passenger and baggage indices computed by hand from AHM charts, per registration, per season.

Loadsheets built in Word

Formatted manually, signed on paper, filed in a drawer. No audit trail, no link to the flight record.

Everything load control needs, in one screen

Built into the DCS, not bolted next to it.

Live passenger scope

Calculate on all booked or checked-in only. Counts, bags, and seat rows flow from check-in as they happen.

Compartment load planning

Baggage, cargo, mail, and ballast per compartment, with max-weight limits enforced per position.

Auto-balance

One click suggests the distribution that lands ZFW CG closest to your configured target. Review before applying, nothing commits silently.

Envelope check per phase

ZFW, TOW, and LDW plotted against the certified envelope with forward and aft limits. Out-of-envelope flags before the door closes.

Loadsheet in your language

AHM-format loadsheet generated in the airline's default language, with LMC section and signature blocks.

Check-in feeds the calculation, live

When a passenger checks in, adds a bag, or changes seats, the W&B module already knows. Passenger counts by type (adult, child, infant), bag weights, and cabin seat distribution flow from DCS in real time - no exports, no re-keying at close-out.

Auto-balance that shows its work

The system suggests a compartment distribution that brings ZFW CG closest to your configured target - and labels the result honestly, including when limits make the target unreachable. The controller reviews the full table and applies or edits manually.

Every phase, checked against the envelope

ZFW, TOW, and LDW each computed with weight, %MAC, and envelope status. The breakdown panel exposes the underlying math - DOW, DOI, loaded index, passenger and baggage indices, fuel index. Nothing is a black box a controller can't verify.

From calculation to signed loadsheet in one click

The generated loadsheet carries weights vs limits with underload, compartment distribution, passenger breakdown, cabin trim, per-phase %MAC and CG arm, warnings, and an LMC section for last-minute manual corrections - in the airline's language, ready for signature.

Coverage

Allpartners

W&B is live in production across every airline running on Farel.

Fleet

Anyaircraft type

Envelopes, compartments, and index data are configured per registration.

Architecture

DCSnative

Same record as check-in and boarding - zero data transfer.

Built on AHM, configured per registration

Load control runs on IATA methodology, with every aircraft-specific value held as configuration rather than code.

AHM 560/565 methodology

Index and CG calculations follow IATA AHM 560/565. Reference arm, MAC length, and index formulas per aircraft configuration.

Per-registration configuration

DOW, DOI, compartment layout with max weights, certified envelopes (forward and aft limits), and crew codes configured for each tail. New registration, no code change.

Seasonal standard weights

Summer and winter passenger weight sets applied automatically by season; adult, child, and infant weights configurable per airline.

Crew variants

Standard and alternative crew codes (e.g. P2C3) adjust DOW/DOI per flight without touching base configuration.

Real-time DCS sync

Passenger scope, bag counts, and seat rows read directly from the check-in record. A gate change or offload is in the calculation the moment it happens.

LMC on the loadsheet

Last-minute changes recorded in the dedicated loadsheet section for manual correction and sign-off, per standard load control practice.

FAQ

Before you decide

Answers to the questions we hear most from airline teams.

Any type. Envelopes, compartment layouts, DOW/DOI, and index parameters are configured per registration during onboarding. The methodology is AHM 560/565, which applies across fleets.

Directly from Farel's DCS. Checked-in counts, bag weights, and seat distribution sync in real time - the controller chooses whether to calculate on all booked passengers or checked-in only.

Yes. Auto-balance proposes a distribution and shows the full per-compartment table before anything is applied. The controller can edit any load line manually - type, weight, and note per entry.

The loadsheet includes a dedicated LMC section for manual corrections and sign-off after the calculation is issued, following standard load control practice.

The airline's default language. The document follows AHM loadsheet structure - weights vs limits, load distribution, cabin trim, per-phase CG, warnings, and preparation signatures.

For airlines on Farel, yes - W&B runs on the same record as check-in and boarding, so there's no data transfer to a third-party tool. Loadsheets are generated, downloaded, and archived with the flight.
