Hey everyone,I have a question to all the people who use FS9 ATC and fly VNAV/LNAV the whole flight. How do you do it on approach when ATC starts giving you vectors and altitudes that are not like your flightplan. If I fly VNAV/LNAV on approach, ATC starts to get mad and they cancel my IFR flightplan. If I then listen to ATC vectors on approach, it's very hard to slow down and decend. I just want to know how you can fly VNAV/LNAV on approach correctly while still having ATC.PS: I know you can make your flightplan VFR but I want to keep it IFR.ThanksAlexwww.fs2crew.comhttp://www.fs2crew.com/betateam.jpg

I setup my flight plan using either the FS9 planner or some other option. I then put the same flight plan into my FMC. Once I takeoff and am given clearance to resume my navigation, I go to LNAV and let the computer fly. At some point upon approach, FS9 wants to vector me to the runway so I use their instructions (like real life) and land the aircraft. You have a choice of ignoring the built-in ATC or acting like it does matter. Some also swear by flying online but that is not my cup of tea.

Thanks,I do the same as you, I takeoff and go into LNAV when given clearence to resume navigation. My problem is that since ATC makes me decend so late, I have trouble slowing down while decending. Is there anyway to make ATC decend you near or at the TOD in your FMC?ThanksAlexwww.fs2crew.comhttp://www.fs2crew.com/betateam.jpg

Really? Strange I actally I never find ATC descending me too late. In fact I often find myself using 'DES NOW' in my CDUs as computed TOD is more often a little later than fs descent.regards,MarkXPHomeSP2/FS9.1/3.2HT/1024mb/X700pro256

I agree with Mark. Perhaps you are carrying too much speed as you descend. R-

This is what I do:As desired include depature procedures / SID / STAR in programming the MCDU with crossing/speed restrictions.On takeoff, I follow the DP and SID but program the ATC cleared alt into the MCP. ATC might complain some about followng LNAV but it usually tells you to "resume own nav". On descent, if ATC isn't giving me a new alt clearance, I request a 10,000 foot decrease about 2 nm prior to ToD and ATC is pretty good about granting. After that, ATC does a poor job of conforming to the STAR, but I tend to let it nag me. Once ATC starts vectoring for an ILS approach, I request the appropriate runway and approach based on my STAR. I often request the RNAV approach rather than ILS (if avail) since the IAF seems to match up better with the STAR. ATC will clear you direct to the first point of the approach. You can continue to follow the STAR in LNAV and VNAV, and let the ATC nag you a little. It depends on the geometry of the STAR. For example, yesterday I did the SUNST1 STAR into KLAS which has you flying south of the airport and then doing a 180 to join the approach into 25L and ATC was unhappy with that, but other times if the STAR is more directly heading to the approach IAF ATC will leave you alone. For example, I've flown the RIICE1 into KIAH a lot lately, and it seems to work out fairly good, at least from the LNAV perspective.scott s..

Thanks guys!I'll try it out!Alexwww.fs2crew.comhttp://www.fs2crew.com/betateam.jpg

Also keep in mind that real automation all the way down is very rare. VECTORS is that - it means you manually set the heading that ATC requests from you and engage HDG SEL vs LNAV. VNAV on the other hand is never used for small altitude changes simply because it is important to have your head up in the terminal areas. The workload on some birds, in such situations, is much more than simply resetting the altitude and pushing LVL CH/FL CH. Some birds, such as the 744 with vnav alt mode, makes it easier to do it yet, this might still apply at higher and larger altitude variations. ...............Randy J. Smith................CAUTION!
