Thanks everyone for your anwsers ! Everything is clear now! Cheerio

Hi! Thanks for your reply, it is the exact type of anwser I sought ! I see now, the point is that I was too much thinking like C172-trimining whereas it is far different, actually! ------------------------------------------------------------------------------ When you say trim up you mean pushing down on the switch to increase trim ? ------------------------------------------------------------------------------ Cheerio! Thanks for the explaination too, very usefull, got a great deal of readings for these holidays !

Good evening everyone! I have flown the 777 (PMDG) for couple months. As I come from the 737, I still a bit skeptical about how the trimming should be performed. So far, I have read FCOM's, I have checked on YouTube videos about it, also I have checked across PPRuNe, but I have not been able to really understand the logic which is behind. Statement: I understood that on 777, pushing the trim switch located on the yoke does not make the stab moving directly -- as it does on 737 --. Instead, it changes the trim reference speed, the speed which is targeted by the current configuration by the trim. For instance : I am at FL080, and I want to descent and keeping the speed, so I just reduce the throttle and push forward. Now I want to make the same but I want to reduce the speed then I push forward and trim downwards -- because I want the reference speed to be lower!-- at the same time (seems contradictory, isn't it ? On a C172 I would trim upwards to get the nose down...), so in this situation I don't know what to do... If someone who knows the aircraft could explain me the correct way of using the trim reference speed, I would be very happy. Have great flights ! Thanks !!

Hi Pete ! Thanks for your reply, I will double check next time :rolleyes: Cheers, Jules.

Hi folks ! I have a problem with my PMDG OPERATION CENTER, when I ask to download the sp1b for the 777-300ER expansion, nothing happens. So, could you please help me to fix it ? Cheers, Jules M.
