ETA instable + Speed and Altitude disappearing in FMC

Featured Replies

Hi, I have a problem with the 737 NGX.First you must know that the SP1 is correctly installed.I did a flight yesterday and I have incounter some strange behaviours in the FMC1/ The ETA. For example, in the DES Page, the ETA for the TO WPT the ETA is complety instable, the value change every second on hour basis, that means that the ETA hour was changing from 11h pm to 02h am, but every second with a different value. ( I was in cruise flight level, but did it in any flight level condition)2/ In my FMC, at the LEGS page, the SPD and ALT caculated by the FMC, was always dissapearing and reappearing again and again, I never had this before.Any Idea ?PS : how uninstalling a livrery not appearing in the Livrery manager but installed using the livrery manager, because when I try to fly with it have an error and cant use this livrery.Franck Birolini

Hi Franck, I dont pretend to know the full answer to your problem plus you have given very little info. about your flight. Regarding your liveries, when you installed SP1 you should download and install a new set of liveries and uninstall the old ones. Regarding your flight and the FMC problem, if you installed a low fuel over a long distance at a high Altitude then the FMC will struggle to cope with this criteria hence the reason for the fluctuations. Could I suggest you refer to the Tutorial and follow the guide lines within and see the difference. Hope this helps. richard welsh.
