# 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.

- AHM 560/565 calculations
- Real-time DCS sync
- Auto-balance to target CG
- One-click loadsheet

## How load control gets done<br/>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,<br/>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<br/>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<br/>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<br/>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<br/>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.

## Live for every airline on Farel

Load controllers calculate, balance, and issue loadsheets on Farel today - on live flights, not demo data.

## Built on AHM, configured<br/>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.

## Before you decide
Answers to the questions we hear most from airline teams.

### Which aircraft types are supported?

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.

### Where does the passenger and baggage data come from?

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.

### Can the controller override the auto-balance suggestion?

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.

### How are last-minute changes handled?

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

### What language is the loadsheet in?

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.

### Does this replace our standalone load control software?

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.
