On the glass-bus, TRK and FPA will fly a specific TRK (and FPA) - it wont actually track a specific radial from a VOR - only if you activate TRK when you are established on a radial will keep you established on it.Mind you, the 767 actually has a feature to fly a track! Unfortunately, 99% of the pilots dont know this trick and I am not sure what FMC version is required (I only know its possible with pegasus FMCs). If you enter a specific command into the scratchpad and LSK it to the top of the LEGS 1/n page, LNAV will fly a specific track indefinetely! I am afraid I dont know the exact wording of what has to be entered :-( But if noone does, I can check in around a week!PS awesome news about the new 767!Regards,Mark

Mark,I guess then, on the glass-bus, it's the same as on the 767, you have to program the fmc, so that you can achieve track following.Can you find out how to fly a track on the 767 as you mentioned? that would be interesting to know,Regards,Francois

As promised, here is the syntax:to fly a course of 270 type in:P/P270 without any spaces. Again, this is confirmed for the pegasus boxes.And nope, I'm not a pilot, at least not an ATP'ist.Regards,Mark

Hey, thanks for the reply..my new question is, does that allow you to follow a course FROM a station/waypoint?

Nope, it will simply fly a specific track after you enter it. If you enter this shortly before passing a VOR, it will be as if you are tracking a radial outbound, but this entry won't actively track a radial, it simply uses IRS coure information to maintain its path.Regards,Mark

Hi,OK, that's a nice one.But then my next question, this is really similar to entering a new waypoint in the format: VOR/radial/distance, when you would enter a new waypoint in a specified course from a known VOR station and at a specified distance and the plane would fly there. That sounds similar to VOR tracking, or am I missing something?Francois

" or am I missing something?"well, not really. But I wouldn't call that VOR tracking as you are not using raw data (VOR data) to navigate, but are fully relying on your FMC position (which may be updated by that specific VOR, but it doesn't qualify as raw data flying). VOR tracking would be if the AP wouldn't care at all about your FMC position and fly the aircraft along a specific radial. Of course, in 99% of all cases, flying a VOR radial in LNAV will be as precise (or even more precise) athan flying it raw data...Regards,Mark

Hi Mark,Thanks for these precisions about VOR tracking, I agree with you, my scenario wouldn't count as VOR tracking. Regards,Francois

Final questionDoes PIC simulate this feature?

Hi,As far as I know, you can program your FMC to come as close as possible to VOR tracking, but that is not VOR tracking in the pure sense of the word in that you are using FMC position and not raw data from the VOR (as explained my Marcom). I think it's the same on the real plane too.Regards,Francois

I don't know!I'd be surprised if it worked, but I have got used to getting surprised when flying the PIC ;-)Why don't you try it out?

>I don't know!>I'd be surprised if it worked, but I have got used to getting>surprised when flying the PIC ;-)>>Why don't you try it out?I know of that "surprised" feeling..and i love it...sure will try it out

FYI, the Pegasus software and 777 allows FROM intercepts using either a wp or your present position. The syntax is WWWNNN, WWW = waypoint and NNN = desired outbound radial (TEB219)Using P/PNNN will do the same thing from your present position. One thing to remember is that the plane will fly a track which, depending on winds, will deviate from the HDG that ATC wants you to fly.
