There seems to be a problem in the 'YBBN_ADEP4_ORBX.bgl' file with the identifiers for Rwy's 01L showing as IABA and 19R showing as IABB. These don't show up on any charts. I think they should be IBN and IBE respectively. This is causing problems with AivlaSoft EFB. Please correct me if I'm wrong about this. Glenn Asher
