I realize a lot of the responses are written in humor, but lest some of
the younger readers get the wrong impression - it is still possible to
properly execute an NDB approach and safely arrive if the weather is
above published minimums. Hundreds of pilots flew LF range and NDB
approaches for many years without killing themselves or their
passengers.


Most of the NDB IAPs flown by airlines was with slaved RMI/ADF
indicators. Those approaches became seldom used by the major carriers
by the early 1960s.
