Currently iaps x75 is used for "Instrument Approach Procedures (IAPs)".
I agree that iaps is not a great name. It does not show up as a suggestion when starting to type instrument... or approach... into the tag field, so people have a hard time finding it. It therefore at least needs a synonym.
The full name of instrument-approach-procedures is also possible, but I think it is unnecessarily long and AFAIK there is no real difference between the terms (Wikipedia at least uses both terms for the same thing).
