Gib is just as bad as Funchal for the unpredictable wind
I've been going in and out of Gib since 1968 and I would hardly describe the winds there as unpredictable. In fact the local wind effects at Gib are probably the most studied and best documented of just about any airfield anywhere. Yes there are problems, particularly on 27 with a Southwesterly. The down and up draughts on short finals have caught out a few people, but they are well documented and fully covered in the relevant pages of the approach plates.
Most of the "Gib Dramas" have occurred not because of the conditions, but through pilots pressing on with landings from destabilised approaches. At Gib (or anywhere) if it isn't right, throw it away, go around, and apply what you've just learned to the next approach.
