Motivation for Automated Tests 2 – Lots of Aircraft Configurations

07 May, 201912

• Airlines want to distinguish themselves

from others

• Leg Room and Seat Density differ

• Different Airline Class strategies

• Light Scenarios and

Boarding Music are used to define

the airline brand

Project Scope

• Automated test system capable of

− Setting all stimuli

− Observing all outputs

− Simulating the aircraft environment

− +5000 pages aircraft specification

− Easy programming of automated test cases

− Easy operation by GUI

− Easy adaptation to various aircraft configurations

− Easy maintenance of the test rig by assisted

self-test

− 3 similar test rigs with slightly different scopes

for sites Buxtehude (2) and Finkenwerder (1)

− +300 pages test rig specification
