I seem to recall that the capacity of the UNS 1B FMS is given at 5MB. But of course, now that I try to find that number in the operators manual I can't find it. Anyway, this is what is listed in the manual : The data base provides the FMS with information on over 100,000 waypoints, navaids, airports and over 12,000 SIDs, STARs and Approaches. Additionally, the data base has the capability to store up to 200 pilot defined routes utilizing up to 3000 waypoints. Later, dudes ! Petter.
