ADF, NDB, Intersections Etc...

When flying on FS2002, I can tune the VOR's etc... and fly from airport to airport via VOR to VOR, but I do not understand how the intersections and NDB's work. Usually, if I have to pass over an intersection, I'll measure out the distance from the last VOR to the intersection, and make the turn once I have reached the distance. This doesn't seem all that correct to me. How does one tune in an Intersection, or NDB, and properly navigate towards it. Also, how does the ADF work? How can I get it to find the direction I'm supposed to be going?
VOR to VOR is good for me for now, but I've always wondered about the NDB's and Intersections...

the eaiset way I would think is to go the the lesssons in FS2002 and c if it is explained there so you can get the visual idea which might be explained eaiser

well intersection arent radio aids but NDBs are. the ADF radio is the radio ull use to tune into the NDB. simply go into he map view and find out the frequency for the NDB then tune it into the ADF radio. then on the RMI, the NDB needle will point to the station. provided ur close enough that is.
ull know when ur over the station coz the NDB needle will flicker then spin around to the other side.

The way you are flying to intersections seems pretty much correct to me!

As Cosync said, Intersections aren't radio aids.
The way you're using them now is the old way where they were found just by measuring distance from A to B.
They're just junctions where one route intersects with another and can really only be used efficiently by way of an FMS or GPS.
Load up a flightplan (make sure it includes a few intersections), go to the GPS and in menu, make sure the "show intersections" field is clicked with "Yes".
Then load up and go.  Smile

nonononnonoon
dont say that NZ767
thats cheating.
no fun at all by doing that. distances are alot funner and rewarding and willll build ur mind and make u a better pilot. sure GPS exists and is possible to use, why not use the most technical and smarter method.

No Cosync,
Orbit, Landmark and American Pacific standard ops say GPS MUST be used when conducting airline transport flights as per FAR Part blah blah blah rules.
Expect a visit from the FAA.:D

Mind you I know what you're saying but my FS2002 planes are so unflyable manually that I have to use the autopilot and GPS just to stay up in the air; needs a better graphics card and maybe some more RAM.
In fact, I've just dumped the whole thing and reloaded FS2000. Smile

Yea.. I don't do that.. I like to fly VOR to VOR etc.. not with the GPS.. it makes it so much more realistic and fun to fly that way rather than with GPS on. My NAV autopilot selection doesn't work as well as it did in FS2000, in that it overcorrects way too much even 60 miles out, so i end up using the HDG button, and just correcting my heading to stay on course. At least I know I was doing the Intersection thing correctly, and now I know how to tune the ADF.

yeh hi 5 dood.
NDB flying is fun because u can just point the nose at the needle. a bit lazy .
u can use NDBs to find out wot radial are on from the NDB station aswell. u just find out ur heading and transpose that over onto the NDB indicator and whichever way the needl is pointing take 180 off that and that will be the bearing from the NDB station that u are on.
hope that makes sense to u Smile

I have been doing the same as you too Jcxp15. I did start by using the GPS display for navigation, but found that was too easy and made flying the sim like watching water droplets run down a window.

Being in Australia, I do most of my flying around here, which adds more challenges to the game. Australia has nowhere near the amount of navaids as, say, the US or Europe, so calculating distances is a must. I have had to do things like fly at a NDB with the Course set for the next VOR, turning when I intercept the course.

I try to fly all my flights this way now, judging my performance on how many course corrections I get from ATC.

Intersections are formed by intersecting radials from two different VORs or by a VOR radial/DME distance combination.

Fixes on the other hand are just arbitrarily chosen points to be used by RNAV capable aircraft.

An ADF (Advanced Direction Finder) is the equipment used to receive an NDB (Non-Directional Beacon). It basically shows the direction to fly to get to the NDB. If you are to fly a given NDB track, position yourself so that the ADF needle points to the required heading. This is made a lot easier if you have an RMI rather than a pure ADF, as the RMI (Radio-Magnetic Indicator) incorporates a directional gyro so you don't have to watch two different instruments.

I can higly recommend Tim's Air Navigation Simulator to those who want to grasp navigation using radio beacons.

While many airspaces these days require RNAV capability, understanding radio beacon navigation is still a skill required to fly many procedures.

Cheers,
Fred



I thought I was doing good trying to avoid those airport hotels... and look at me now.

on flight simulator the NDB indicator has a heading selector where u can turn the compass behind the needle aound to the heading u are on. this allows u to use it sort of like an RMI. but RMIs are still way easier.
