Have a slight issue with VNAV in that once airborne and LNAV, VNAV and CMD are selected the aircraft only climbs at around 100 to 200 fpm!!! This takes about 300nm for it to reach it's programmed altitude. The only way I see to get it there quicker is to select flight change and adjust rate of climb manually. In doing this the aircraft then slows down to a stall and no matter what one does to rectify this, kiss bye bye to your flight.

Anyone have a solution to this other than "read the manual" as I have done

Enter the initial altitude of say 2000ft including speed. on reaching that I then enter the next flight level, say 7000ft including speed (which for Southampton is TA) after that I then enter say 34000ft but leave the speed at 240 as it's below 10000ft. On reaching/passing 10000ft I then increase speed bug to 306 which was calculated by the CDU earlier.

Even with doing this it should still climb at it's optimal 1800ft and maintain it's speed set on the FMC,

The flight plan is loaded via the CDU then I find out active runways and enter the relevant SID's and Star's and as it should be, the CDU should control all aspects of the flight. Nope, the rate of climb is so low if it got any lower it would be in reverse!!

I usually use the Project Magenta's Boeing Suite of software and on default aircraft (737/747) I have no issues although their CDU has a lot more options (as per the original CDU, have the manual) which are not available with this one.

My issue is still the same, I have to disconnect VNAV and manually gain altitude and if I don't keep an eye on things it will go into a stall! This should not be happening and I'm at a loss as to how to remedy it and I cannot hook PM's software into the aircraft.

Hi,

I have an issue where my autopilot does not control heading or speed.  It will control Vertical Speed and Altitude but will not change heading when heading is selected/held or LNAV activated, or change engine speed when speed, autothrottle and/or VNAV are selected.

I have programmed the FMC for a flight, aligned the IRS correctly and gone through the manual several times to ensure correct setup.  When FMC programmed, VNAV functions for altitude but not speed and LNAV does not work at all (even when selected).

The only way I can control my heading is manually (not good for long flights) and speed is manual the entire time.  I have searched the forums and the KB and it just says the same stuff I have already been doing.  I have also uninstalled and reinstalled the aircraft with no effect.  Any help greatly appreciated.

I own and use the latest version of FSUIPC (4.60a) and the Autopilot works perfectly fine.

Mine will climb to the 767's Optimum Altitude at a rate of 1000fpm or more. Are you programming the FMC correctly? Getting the COMPLETE message in the FMC once you have entered all the necessary data?
I know that the LD767 and CS767 FMC are virtually identical, so if you can use one, you can use the other.

That is all very well, but my 767 A/P doesn't work even after re-installing, re-downloading and doing all other tweaks and things in this thread. It simply does not work.
My specs are above the minimum requirements that CS has on their product page.
I have version 1.5.

Nothing works! I can turn on the Flight Director and the Auto Throttle, I can set speed and it will even hold it (the only things that works!).

I have tried it on several routes, long-haul (TXL-JFK), Short haul (LHR-HAM), medium-haul (MAN-FNC). I have paid a lot attention while programming the FMC.

I am NOT able to click on ANY button on the MCP except for the EPR, SPD and SEL button.
My vertical speed gauge on the MCP does not work too.

Luckily did I only pay 9,99 for it but it is still sad to know that it is a waste of money, because there seems not to be any solution for this problem.

Seems like that I have to stick with my another company products until this CS problem has be solved.

Merry Christmas!

We may need more details and maybe a screenshot of the situation.
