I too find it odd that a SID designator for a particular runway may have one defined track that is different to the same named SID for another runway.
On another cultural note: I have wondered what technology Malindo has on their aircraft that allows them to reliably land in BNE during dense fog events that send other airliners to their alternates from the missed approach. One of their pilots assured me that it was solely the effect of the low fuel lights that sharpened the senses and honed the visual acuity. Maybe we should do that?
