Talk:Line-replaceable unit

Removed a line saying that LRUs are commonly referred to as black boxes. If anyone can source that it can go back in but I think it's wrong. Black boxes are LRUs, LRUs are not black boxes. 208.78.72.18 (talk)

In aviation, LRU's are not strictly electronic. LRU can apply to any type of assembly, mechanical or electrical. —Preceding unsigned comment added by 12.232.11.213 (talk • contribs) 06:49, 31 October 2003

Definition of a Line-replaceable unit[edit]

Unit which can be exchanged / replaced at a given time (usually when the unit is faulty). The definition of the unit depends on spares and tools available, the skills of the persons exchanging the unit and urgency to replace the unit. —Preceding unsigned comment added by 217.194.34.103 (talk • contribs) 11:41, 27 October 2006

Orbit Replaceable Units[edit]

Orbit Replaceable Units (ORUs) are mentioned in the article, but I'm not sure they match the current definition of items repaired at the organizational level. I would imagine support echelons for space stations would include ground support, and also spares inventory for unreliable parts on the station itself, but I'm not sure how these would map into the traditional USAF organizational, field, and depot support levels. As always, citations help to gain perspective. 70.251.149.197 (talk) 18:54, 20 February 2009 (UTC)[reply]

Air Transport Rack (ATR)[edit]

Since ATRs are a type of LRU shouldn't they be listed under this article? I don't see any reference to ATRs in the LRU article. Also, there are articles that reference ATRs, but there isn't a specific ATR article on Wikipedia. I think it would be proper to direct the ATR links to the LRU article. Any thoughts?
