Things to Remember:
Figure out now so aircraft not thinking about it.
formulas plain rote memorization
DME: back and forth queries. an ident every 30 seconds on a VORTAC, VOR-DME indicates only DME op, VOR inop.
DME can be used instead of OM, BC FAF, other fixed. From a separate facility: ARC IA Segments, BC FAF, and OM
IFR Certified GPS can be used forADF and DME when . . .
SDF = 6-12 degrees
MLS : not here
LORAN-C: see Jepp video and AOPA handout. 27 transmitters. 
OMEGA: gone 1997
INS: Big guys
Doppler : see above
FMS: see above
GPS: RAIM required for IFR, more details later
