Service · Weight & Balance / AHM 565

The AHM 560 is history. Your fleet moves to AHM 565, substantiated and in X565.

IATA's Airport Handling Manual, Edition 47, retires the AHM 560 and installs the AHM 565 and its XML twin, the X565. We take your AHM 560, your Weight & Balance Manual and your LOPA, and return the complete package: the AHM 565, the X565 your DCS loads, and the Loading Schedule Substantiation that proves every figure in them.

Twenty-seven years of building weight & balance systems, from the 707 to the 777, across Boeing, Airbus, Bombardier and more.

The change

The standard changed. We are already there.

The AHM 565 is the data your departure control system runs on: envelopes, curtailments, fuel, cabin, holds, dry operating weight. The X565 is the same data as XML, exchanged between manufacturers, airlines and DCS providers and checked against the IATA schema. Most operators will discover the change at their next DCS audit. Ours receive it as a delivered package.

What we deliver

Three documents, one build, zero disagreement.

Loading Schedule Substantiation document, section 8: development of operational limits

Substantiation

Every number has a page number.

The Loading Schedule Substantiation records how your loading schedule was built, in the format Boeing uses for its own: data sources, curtailments, operational limits, trim, appendix per registration.

  • Developed to FAA AC 120-27E and EU-OPS 1.605, with the method stated, not assumed.
  • Manual section and page cited for every limit, arm and constant.
  • Curtailments derived: gear and flap retraction, passenger seating variation, fuel density and usage, cargo, in-flight movement.
  • The document your authority, your auditor and your DCS provider can all read.

Balance chart

The envelope, drawn from the same build.

The AHM 519 balance chart and loadsheet come out of the same data as the AHM 565 and the X565: operational envelope, fuel index table, cabin and hold scales, per registration.

  • Certified and operational limits with every curtailment applied and labelled.
  • Taxi, zero fuel, take-off and landing checks on one chart, per thrust rating.
  • Printed, signed, and matched against loadsheets you already use.

Curtailments

We design your curtailments. From this, to this.

On the left, the certified limits exactly as the manufacturer publishes them, per thrust rating. On the right, the operational check grid your load control actually uses: the same envelope curtailed for gear and flap retraction, passenger seating variation, fuel density and usage, cargo and in-flight movement, with the restricted-landing zero fuel check and the DOW plotted inside it.

X565 XML validated against the IATA schema

X565

Validated before it reaches your DCS.

Every X565 we deliver is checked against the IATA schema, with the open items listed, so your DCS provider receives a file that loads the first time.

  • IATA X565 schema, current edition, zero errors or it does not ship.
  • Files you receive from manufacturers or DCS providers read and compared with yours.
  • The same data as your AHM 565 and your Substantiation.
01

From the manufacturer's manual, not from memory

Manual, LOPA and weighing report become the loading schedule: curtailed envelope, stabilizer trim, DOW/DOI per crew configuration. The Substantiation records how, page by page.

02

One build, three deliverables

AHM 565, X565 and Substantiation come out of the same data, so they cannot disagree with each other. The X565 is validated against the IATA schema before delivery.

03

Proven against loadsheets you already signed

We reproduce your operation's own loadsheets and put the figures side by side. Matching is the acceptance test, not a promise.

Twenty-seven years, every manufacturer, one standard. We have built weight & balance systems for fleets from the 707 to the 777, Boeing, Airbus, Bombardier and others. Today Fulcrum runs that engineering on the ground and eLila EFB runs it on the flight deck. Keeping your own DCS? We deliver the X565 it loads and the Substantiation that defends it.

Send us your AHM 560. Get back a fleet that is audit-ready.

One document and one signed loadsheet are enough to come back with your AHM 565, your X565, your Substantiation and a scope for the rest of the fleet.
