What are the Necessary IFR Navaid Instruments in 2020???

I'm doing a lot of research online, and I'm new BTW. I'm finding lots of new and older material to learn from for free before I start a tab with the pros. Makes me look sharp.

Thing is that I think some of the instruments used and explained in the free online archives are out of use on the planes these days or going out of use. It may be useful to learn how to use them all since who knows what's going to be in every plane or airport, eh.

Which instruments going out of service these days, and what's the absolutely necessary to fly with for approach/depart? Thanks

The NDB approach wasn't required and we were going to do a LOC but the examiner thought it would be fun since I'd never done one before.

They thought it was fun :emoji6: I guess you really do need to know how to use all the functioning equipment in a plane on the checkride.
