What am I doing wrong - holding 744-Cruise Levels? ;)

Recommended Posts

Hi,Using the PMDG 747 passenger Air Canada livery, my Fplan was direct CYEG-KSFO at 370. The airplane load was was 2/3 pax, and sufficient juice to get there. FMC appeared to be happy with the FPlan, the route seemed complete and altitude select was 370. I used Vnav/Lnav to get to altitude, got there and all seemed well. Then I noticed alt alerts and a porposing of either climb or descent even with the alt set to hold. A/T was active and maintaining good speed, but the airplane was tough to keep level until well into the flight. The approach was even more abissmal so it's got to be something I'm NOT doing correctly.All suggestions appreciated.Ron_CYEGhttp://www.precisionmanuals.com/images/forum/747400.jpg

Been there, done that! My two cents (and if you have already done apologies for repeating)Make sure you have the latest version of the Queen. I had this problem before I updated. Patch seemed to fix somewhat.The other thing two is make sure that you are not trying to go to high for the weight of the plane. I know that the heavier you are the lower you should be flying. Try to fly the exact same route with the exact same configuration, but try setting your cruise alt to say FL300 and see if you have the same issue.Bretthttp://www.precisionmanuals.com/images/forum/800driver.jpg

Brett:I have the new version, but the problem persists. I reduced altitude to 290, but this time I not only couldn't solve the porposing, but couldn't get the A/P to engage. Big smack followed! ;(Ron_CYEGhttp://www.precisionmanuals.com/images/forum/pmdg_pf.jpg
