Yep in 1976 I flew the then Indonesian Minister for Aviation and his group of 10 into Nalca - my favourite strip:
7500 amsl, 1200 ft long
1st 300 10%, 2nd 300 15% 3rd 300 10% and last 300 24% - 30 ft wide.
when he hopped out wide eyed I asked him what he would class the ALA as - he replied “ Goat Strip”
