Ralph Freshour has posted in the PMDG forum at Avsim a series of YouTube videos with very instructive tutorials on Ralph´s Basics Boot Camp Series “How To Fly A Perfect ILS”.
Videos 1 and 2 are Ground School basics on how to correctly set up for the ILS approach.
Videos 3 and 4 are PMDG 737NGX simulator demos on, respectively, flying a Boeing standard ILS and a non-standard ILS.
There will be a 5th video with another flying demo, available within a few days.
Get these very informative videos at Ralph’s YouTube channel.
