Thank you for your reply,so the no loc. stays on the whole fligt,until I get ready to make a landing at an airport,making an ils approach,then it goes away,is this correct.
Yes. With no signal present there will be no output from the receiver to the displaying instrument. For example, at 100 miles south of Seattle, you're going to use the NAV1 radio, tuned to the Seattle VOR signal - 116.8; you will then rotate the heading knob at the bottom of the VOR indicator to the heading you want, say 325 degrees: when your nose is pointing at that VOR station and you are on a heading of 325, the vertical bar will slide over to the center. As you wander left or right off that heading the v bar will also move off center. Now you need to get the aircraft back on that heading, and as you do so - the bar will again center. You actually fly toward the bar, using it
as the indicator for the direction needed. Around 25 miles or so from KSEA you will tune that same NAV1 radio to 110.3, which is the ILS frequency for 34R (for e.g). - and you'll then find that "no loc" flag will disappear, as the localizer receiver now has a signal. Pressing the ILS button on the panel will link the autopilot to that localizer signal, and the aircraft will turn to track the beam, with the v bar now indicating your position to the left or right of the runway, and moving the aircraft to center the bar - and of aligning itself with the runway centerline. (You can also accomplish this without the autopilot, flying manually).
The rest of the aircraft management at this point is a whole different discussion, and will no doubt need addressing at some other time.
Here, Mark, I will advise you to get back to a slower, basic piston engined instrument trainer. There are a number around, both freeware and commercial - plus those supplied with FSX. Read all you can on VOR, ILS, ADF, and GPS, plus, of course the FMC, as you will need to be fully conversant with these system in order to fly the Maddog.
It is unfortunate that you seem to have chosen this particular aircraft before learning and understanding basic aviation navigational systems, because her management is most realistic and unforgiving, and will not give you the opportunity to learn in depth while you fly, whereas a slower, simpler aircraft will let you build up the necessary skill and experience without constantly having to restart over and over because of some small issue not understood.
