In addition to other member's suggestions, few more changes are needed
VABB gate numbers are completely wrong. The International terminal gates are numbered as V and start from V4- V30s and domestic gates are numbered A1 to A12.
International cargo bays are not simulated. ( These are opposite Gate V6 to V11)
Runway 14/32 is rarely used ( only when main runway is under maintenance)
This airport has tremendous potential to be a nice scenery
