IENA PACKET FORMAT<br />

JP.CATURLA<br />

AIRBUS INTEGRATION TEST CENTRE<br />

To increase the quality and the pertinence of the test results provided to design offices, Airbus launched<br />

the ambitious project named IENA (Installation d’Essais Nouveaux Avions = Flight test Installation for<br />

New Aircrafts)<br />

This project leads to a complete review of the acquisition, recording and data processing format.<br />

The name of the new data format defined by Airbus is ‘IENA PACKET’. The goal is to carry under one<br />

unique format all the measures provided by flight test equipments with an accurate time tagging and<br />

minimum data.<br />

This paper describes the format of ‘IENA PACKET’ which will be used as a standard by all new test<br />

installation equipments.<br />

Introduce :<br />

The IENA high level principle that led the IENA PACKET format are:<br />

- The test installation provide an unique time base (GPS or internal) to the acquisition and recording<br />

systems. All test means (flight ,ground and external) are synchronised with the same time source. A<br />

parameter is time stamped with the time of its creation<br />

- The recording data process are either continuously (Sample frequency or repetitively cycle) or on<br />

asynchronous event<br />

- Test installation means and decoder exploitation tools have one unique data stream format<br />

The next part of this article describes and emphasises all fields of the IENA PACKETS format.<br />
