So I shouldn't leave it to the autopilot to follow the FMC down to the airfield.'Īlternatively, if you want to follow the pre-programmed FMC solution, there is no problem with that, but it may not be as accurate. (did you learn the default aircraft first, or jumped right in with the PMDG?) The signal is recieved by the aircraft and the autopilot the follows that signal. Note(2): A glideslope is a signal that is sent up into the air from a transmitter that is located at the runway. Note(1): Not every glideslope is 3.3 degrees in real life, but I think in fsx most are that angle. This is not only so in FS(X), it is how a glideslope works in real life too. Then, at exactly 10NM it intercepts the glideslope and starts to follow the signal down. That is the point I engage approach mode.įor a few seconds the plane keeps flying straight on. Getting closer I start to see the glideslope indicator moving down when I'm 14-13 NM from the TDZ. I usually come flying in at 3000ft above the ground.Ģ0 NM from the RW I recieve the glideslope, at that distance the glideslope is above me. There I want to have the plane follow the glideslope down. I imagine a point 10NM from TDZ, at 3000ft where I want to end up. So, 10 NM from the touchdown zone, the glide slope is at 3000ft.Ģ0 NM from the touchdown zone the glideslope is at 6000 feet. However, there is a simple relationship between distanc vertical and distance horizontal on the glide slope. This is the relation between distance travelled vertically, and distance traveled horizintally. The glide slope has an angle of 3.3 degrees. This text just explains how to catch the glideslope in a default aircraft (like the b747_400 or 737_800 for example). I know nothing of the PMDG FMC, and it's particular autopilot modes. This is a general explanation about default aircraft,of the glideslope and how to catch it.
