i think we are mixing things, onces its the cap 371 or the spanish version anex 16b, i dont know anything abaout cap 371. but i know quite well the anex 16b, and what its all about its maximum activity depending on your cheking time, mumber of legs, maximum a month, three month and a year, it is not a programation tool, at least in spain there is no company whit a roster system like 5453, just click air because they have copy most of the terms of ryr, not even iberia have something like this, (this is why i want to try ezy)then its compatible appllay 16b with a 54 53 system, there are two diferent things, anyway, my interview its on the 18, and off course i will ask for this specific subjet and i promise to tell in this forum what ever they tell me
