The Jepp chart training CD recognises VOR, NDB, LOC,GPS and LDA approaches as non precision.
The DME element is regarded as an extra and will be specified, although the "raw" apporach using timing is still valid but to higher minima.
The NDB may be a locator or an ndb: the LOC is the localizer element of an ILS installation the LDA is a displaced localiser approach i.e offset by up to 15 degrees.
