Abstract :
IENA PACKET FORMAT
JP.CATURLA
AIRBUS INTEGRATION TEST CENTRE
To increase the quality and the pertinence of the test results provided to design offices, Airbus launched
the ambitious project named IENA (Installation d’Essais Nouveaux Avions = Flight test Installation for
New Aircrafts)
This project leads to a complete review of the acquisition, recording and data processing format.
The name of the new data format defined by Airbus is ‘IENA PACKET’. The goal is to carry under one
unique format all the measures provided by flight test equipments with an accurate time tagging and
minimum data.
This paper describes the format of ‘IENA PACKET’ which will be used as a standard by all new test
installation equipments.
Introduce :
The IENA high level principle that led the IENA PACKET format are:
- The test installation provide an unique time base (GPS or internal) to the acquisition and recording
systems. All test means (flight ,ground and external) are synchronised with the same time source. A
parameter is time stamped with the time of its creation
- The recording data process are either continuously (Sample frequency or repetitively cycle) or on
asynchronous event
- Test installation means and decoder exploitation tools have one unique data stream format
The next part of this article describes and emphasises all fields of the IENA PACKETS format.
