A question about FSNavigator and ILS

Ok,

Yesterday, I tried setting up and doing a flight from KVQQ to the USS JFK, off the coast of Jacksonville, FL.

Setting up the flight was easy enough. Brought up FSNav, positioned my aircraft (Razbam Intruder) at KVQQ, and then selected USS JFK (AC01), ILS runway heading as destination.

The NAV Freq was correct. Everything seemed to be ok, but tried flying in autopilot, the aircraft did not respond correctly. When it reached the BOD point, it kept going straight for the carrier, instead of turning to make approach. It did descend, but that was all it did.

Any idea what I did wrong to set it up to use autopilot?

Thanks.

I don't have that Intruder. Does it's AP system have the approach-hold feature activated in the aircraft.cfg? Sounds like it does but I don't know why it wouldn't have captured the ILS. How sharp was the your approach to the ILS? I've had problems in fast planes if I don't enter the beam within about 30° of the approach course. I think the plane just overshoots the beam and won't capture it long enough to begin the final approach.

That said, I don't use FSNav to set up & control the autopilot either. I just use it as a moving map and I punch the number into the AP manually.
 
FS ILS is hit or miss - even when you do everything right - at times, particularly getting it to capture the glideslope. That said, in FS9 you can usually count on following the ILS down to the Big E.

Did you, as suggested, press the "approach" button? You need to be at about 2200 - 2500' altitude, "on speed" (dirty/everythign hangin out) AND you need - it's what I forget most often - to make sure your GPS is switched to NAV before pressing Approach. It won't work if it is still set for GPS.

Will check on the "approach" button. But don't believe there is a GPS for that Intruder. NC
 
FSnav should take you down on the ILS, it will select all the frequancies and everything, technically there is not a lot for you to do except monitor your speed and flap settings.

I do not have the intruder but FSnav will set out the flightplan based on the aircraft you input (via the aircraft icon) so if you do not have an autothrottle on your aircraft it will probably mean that you will miss your descent point. This is because you are not flying at the speed FSnav has allowed for on the flightplan.

Hope this helps.
 
Put your pointer over the end of the runway with the ILS. In the right spot it will show the ILS Glideslope information. Not all ILS Frequencies have Glideslopes. The glideslope information will say something to the affect "1500ft @ 5nm distance" could be higher but this is the intercept height. If you are over it you will not hook the slope. Moparmike is correct no more than 30 degrees on the intercept angle or you will blow threw it. Last thing to remember have your NAV/GPS switch on NAV. Thats pretty much all there is to it.

That's most likely the problem. I know for a fact that the aircraft I selected was the Tornado, because the Corsair was not on the list. I have to add it, and haven't taken the time to look up the data to do so. And am sure the speed was not correct.

Gotta check all this. Thanks guys!
