May 30, 201610 yr Hi people! This is my first post here, and its regarding Wilco's EMB FMS. The fact is since I have this product, which is quite nice though, i've been having problems on inpunt the ALTN airport in the FMS. Once I've completed all the tasks, like F-PLN, PERF, etc, I go to ALTN FPL PAGE and when I put my alternate airport in the LSK, nothing happens. Well, in fact, the FMS shows me the CANCEL - ACTIVATE buttons but the LSK remains empty also if I press ACTIVATE; off course I also can't perform an ALTN FPL or a ALTN PERF FPL. Isn't an estructural problem initially. But is quite annoying. Thanks in advance for any help!
