The calculated TD by the FMC must not be blindly trusted in any plane, sim or real world aircaft . Sometimes it's spot on and sometimes the FMC is far off. One has to double check even in a real 737. The accuracy also depends on the waypoints and if they have above, below or at altitudes restrictions. Use whatever mode you like in order to keep your speed and profile within the box and/or ATC instructions. Level change and V/S mode, both have their advantages and disadvantages in a given situation. I like using both and there are many things one should know about these modes. What and how the speed is controlled, what the throttles do, kicking in of speed protections and so much more. There is plenty of quality info about these mode available on the web. Here is some quick info on how to quickly calculate your TD. Every pilot should know this anyway. Even if you have VNAV. http://thinkaviation.net/top-of-descent-calculation/

Update: I deleted the preference folder and created a new one.. It seems to have solved it.. Cockpit lights are behaving normal again... Sent from my SM-N9208 using Tapatalk
