Again thanks Mark for the help and advice !

One more thing when at cruise alt and I see a waypoint in the FMS that I need to descend down to ex 18,000ft to 14,000 and its in LNAV and VNAV mode with the autopilot on.

* Do I have to manually set the alt and vsi to 14,000 /2500 fpm in the autopilot???
* Is there a way that the plane can do this alwready by itself?
* By reading the manual for the it says the I have to set it manually is this the way you do it???
*how do i get my ifr clearence it just says grond or atis i tune in the clearence frequency but i cant get my clearence unless im in the air?

If it's a part of the STAR/TRANS altitudes, then the A/P should be close to the altitude or even holding it by the time it gets there. If it's in the middle of the route, then I think you are flying above that maximum altitude for that part of the route (I've never seen in the middle of a route). So if it's in the middle of the TRANS, you must set your altitude on the to that altitude or lower before (about 10-20nm) you reach the T/D. I usually set my altitude to about 4000' and let the A/P hold the TRANS altitudes when it gets there.

To be honest, I almost never fly IFR, because the FSX ATC doesn't quite do the job right in my opinion. I fly VFR 99% of the time with the big jets.

But is there a way to get you IFR Clearence when on the ground ?
When Airborne @ Gear up I put LNAV Engage the center autopilot then VNAV and push the climb button and retract my flaps I go to my cruise alt then when I need to Descend like it says on the FMS on LEGS it still stays on my Cruise alt and doesnt descend. Why does it not descend like the FMS says? so I decide to do the altitude manually and I have to stay ahead so I can be at the proper altitude.

Also this is weird I had the ILS24L in the FMS and was at the G/S Intercept area but the G/S never showed up in the Atitude Ind. and it was on the correct frequency 111.70 with a 249 Course) the g/s that shows up on the Atitude Ind. came on when I was at the other end of the runway why when it was properly set up? did I do something wrong?
I am learning as like most people but I bought this when It came out almost forgot all about it and decided to learn it thanks for reading this long post -Bruce-

Yes there is. You need to create the plan using FS Flight Planner, and your first problem will occur here because the Nav Data is outdated and there are no SIDs and STARs. Then load it into the FMC AND the flight, then you ready to do an IFR flight. To find out more onloading the MSFS flight plan into the FMC read page 37 of the FLIGHT MANUAL Part V – Flight Management System.

About the descent. Are you setting a lower altitude on the MCP before T/D? Is there a T/D showing on you flight plan?

It should switch to the correct frequency and heading by about 7-10nm, sometimes even further out, from the ILS runway. You can go into the NAV RAD section of the FMC (FLIGHT MANUAL Part V – Flight Management System p45) and copy and paste the ILS - MLS and this will force them into your ILS Control Panel.

Hope this helps

I only start descending when the next waypoint is at a lower altitude.

Is there a T/D showing on you flight plan?

Yes, it shows a T/D but when I pass it, it does not start descening

Yes, otherwise you'll get RESET MCP ALT in the CDU scratchpad.

1) Make sure VNAV is activated.
2) Set MCP altitude to G/S capture alt or to a longer constraint (e.g. when 7000ft is displayed right to a waypoint on LEGS page more than one line in a row or whether if it is in larger, bold-like font). If unsure, just set it to G/S intercept alt.

I seam to fix my problen with the g/s iono why but my ILS for 06R/ILS24L dont work but the ILS06L/ILS24R work so I used them instead and I also figured out what my problem for the alt  descending I was getting a reset MCP ALT on the scene so I just set it to the FMS Alt and had it set to LNAV and VNAV and I was good thanks everyone for the help now lets have some fun!

Hi guys... On 3 Sephtember I have the New York Real Traffic Event on IVAO, And I need to fly with 767. I know hot to use it.. but I never try a long with this aircraft.

How can I insert Step Climb in CDU?

It should say on the Init Page Step Size, then under it says ICAO, replace it with 2000. Use a manual to help. Lets say on a flight from Atlanta to Heathrow your climbing to FL310, after a while, once you burn some fuel off, climb 2000 feet once on the VNAV page, go to the Optimum Cruising altitude. Just go in 2000 feet increments. Hope this helps.  Smiley

I fly at initial level of 320, but when I go to the LEGS page, I can see only 320, not the others level like 340 or 360...
and I have insert 2000 in step size...

I put for final level 320 and not else...

I do somthing wrong?

Or i can see steps in legs only when in flight? Tongue

Not 100% what your talking about, but you will manually have to change your cruising altitude in the FMC and MCP, then it should climb at a very shallow angle. It's pretty complicated at first, but you'll get used to it. Itshouldn't just say that altitude. I'm not 100% sure if this is the way real pilots do it, but it should work similar to that.

Hi Alberto.

If you want to increase your altitude (step climb) during a flight, the first thing you need to do is set the  STEP SIZE (ICAO is the default setting which is 4000 feet) on the PERF INIT page of the FMC. You can change it to 2000 feet if you like.

Having done that, during your flight, you need toi keep an eye on the PROG page and it shows the distance to the next STEP CLIMB (only after reaching you initial Cruise altitude). About 20nm before that climb, change the altitude on the MCP to that next height from 32000 to 34000/36000, (the S/C ALT is determined by your STEP CLIMB setting) according to your flight then enter that into the FMC using Left LSK1 on the VNAV Page 2/3 (CRUISE PAGE). Return to PROG and press EXEC when the it informs you to do the step climb NOW. It's quite easy really.

Hope this helps.

Tanks! now it work.. But a problem:

I have to insert the step climb in the Figt Plan, on MD-11 (the aircraft I use more) when I insert the step, The CDU schow me the poi where I have the steps in the F-PLAN page (the equivalent of LAGS page). Is this possible with 767?

Hi Alberto.

I assume that that's because the McDonald Douglas FMC could do it automatically in real life (and it's really handy). But the "others" 747-400X doesn't do it (a Boeing). Same goes for Captain Sim 757 and 767. Neither does that "other ones" 767! In fact I only ever saw that on the MD11. So perhaps Boeing doesn't have that capability in their FMC.

Mark, haven't you seen s/c on your display?  Isn't that the point for a step climb?

Hi Tim.

Yes I have seen the S/C on the display. I just don't zoom in on it, so I keep an eye on the PROG page of the FMC and when it says NOW  for the S/C, I hit the EXEC button so it starts the climb.

Now with the MD11. Lets say I'm doing a flight from YSSY to KLAX. At first the plane is heavy so the optimum flight level is FL310, but as I lose weight I can climb higher so that by the time I'm 400 miles from KLAX my optimum flight level is FL390. I set my cruise altitude to the maximum altitude for the flight, in this case FL390. In the FMC I have told it my flight levels are 310/330/350/370/390 the MD11 climbs to 310 and once it's weight matches the weight for optimum for FL330 it will AUTOMATICALLY start the step climb. I can go to bed on a long distance flight and when I wake up, the MD11 is flying at its optimum altitude for its current weight.  But if I went to bed on a long flight in the 757s, 767s, 747s which have an FMC and you have to TELL the plane when to do the step climb, I would come back to a plane flying at say FL330 when its optimum altitude is FL390. Because I never entered the new altitudes for the Step Climbs. If I had dialed in 39000 on MCP, then it would immediately climb to that altitude, even if the optimum altitude was 31000 (and it would really struggle to reach that altitude).
