I principally work to Air Publications the bulk of my work being aircraft related but recently discovered that a substantial number of APs have been scanned and transferred on to TDOL. I only found this out when attempting to access the 27mm Mauser AP on the Tornado Digital AP to find it was no longer there. We'd had no notification of this happening nor was I able to find any reference to it happening anywhere. Even though the majority of the publications I require are simply scans of the most recent hard copy the T&Cs at the TDOL front end still carry the caveat of "Hardcopy reproduction is valid only on the date of print and should not be used or retained beyond this date." A sensibly implemented system that enables hard copy printing and the ability to incorporate amendments easily doesnt seem to be beyond the realms of practicality (Battlebox manages to do it) but we seem to always get lumbered with a half arsed cheap cop out system that's full of holes, e.g. pubs put up online with glaring errors in them like incorrect amendment states listed at the front on the book and why so many different online servers anyway? (TDOL, Battlebox, Defence Intranet, various aircraft IETMs & DAPs) Also I loved the effort that went into skewing the scanned pages of the LMG AESPs so the figs of the guns were level, not taking the deployed bipods into account . Anyway what is the general consensus of opinion regarding TDOL and other online technical documentation systems? Does anyone else who has to use them on a day to day basis find them practical when put up against traditional hard copy APs, AESPs and ACs?
