CASSIDIAN Launches Answer to “No Fault Found” Servicing Issue for Electro-optical Equipment

  • Mil­lions of pounds could be saved over life­time of equip­ment by remov­ing need for unnec­es­sary return and repair.
  • Deployed equip­ment remains in-ser­vice where troops need it.

15 Sep­tem­ber 2011 – Cas­sid­i­an launch­es the OLISE elec­tro-opti­cal tester at DSEi in Lon­don this week. 

A recent inter­nal study by Cas­sid­i­an esti­mat­ed that on a land plat­form fleet of 450 vehi­cles a sin­gle Line Replace­able Unit (LRU) type could be expect­ed to incur £4million of unnec­es­sary No Fault Found (NFF) costs over a 7 year life. Stud­ies from the civ­il avi­a­tion indus­try have shown that between 20%-60% of elec­tron­ic units returned for repair are typ­i­cal­ly NFF

The answer is “Gold stan­dard screen­ing”. This involves tak­ing a ful­ly func­tion­al “Gold stan­dard” item, and “learn­ing” how it should func­tion under var­i­ous con­di­tions. Equip­ment sus­pect­ed to be faulty can then be screened against the behav­iour of the Gold stan­dard with­out the need for access to com­plex test equipment. 

One such “Gold stan­dard” screen­ing sys­tem is Cassidian’s elec­tro-opti­cal tester – OLISE — intend­ed pri­mar­i­ly for use in test­ing small­er opto-elec­tron­ic sys­tems crit­i­cal to live oper­a­tions: gog­gles, vis­i­ble and infrared cam­eras, laser rangers and des­ig­na­tors, sights and image inten­si­fiers. The equip­ment can also be used to test opti­cal sys­tems on air­craft with­out the need to remove the equipment. 

Designed espe­cial­ly for deploy­ment in small, local work­shops the sys­tem is a field trans­portable device offer­ing reduced stor­age space and in field logistics.
