Actually your point makes a lot of sense, if I am correct some of the aircraft still used today by the Portuguese Air Force are pretty old in terms of cockpit equipment, specially the helicopters. I have flown with some retired pilots coming from the portuguese AF and HSI was definitely not an equipment they were so familiar.
