Request from one of you, I try to demonstrate how to program your FMC from Top of descent to Final approach fix, the target is to start an idle descent from top of climb and to keep the thrust on idle until established on the RNP 08 in Jersey, all managed by the PMDG 737 VNAV.
Do you trust your VNAV, check the video and maybe you will change your mind!
For FSiPanel users, you can download the Snapshot used in this video with the link below, just position your 737-800 in EGJJ runway 08 and drag and drop the file in FSiPanel main window, you will then be able to fly the same approach.
