Things to Remember:
See explanation chapter 7, ac 61-27c
Figure out now so aircraft not thinking about it.
formulas plain rote memorization
types of NDBs:
190-535 kHz
LOM = 15 nm
MH = 25 nm
H = 50 nm unless published.
HH = 75 nm
no altitude limitation
ILS Marker beacons, 1000 feet above 2400 wide, 4200 feet long. Should operate in low sensitivity for proper reception.
