The modern FMS navigator does a better job with course reversals than pilots, whether they be teardrops, procedure turns, or hold-in-lieu-of-procedure turn. (positive course guidance throughout the maneuver.)
To which you replied:
Thank you for summarizing why I have stopped flying as a passenger unless absolutely necessary
Yes there are some aspects of the FMS that are pants and need watching - "my" FMC flies a dire direct entry to the Ockham hold as an example
, but given the choice, to get me home, in dire weather, of flying, say, a Non precision approach using stopwatch and heading, or flying the same approach "coupled" using GPS and database for guidance I'm quite willing to forgo the heroics and use my braincells to
monitor the flightpath.... and I suspect the several hundred folks down the back might agree with the more conservative approach.
