can anybody give me some advice - on some planes (currently 777-300er) my plane starts to bob up and down while on autopilot and reducing speed/altitute… got a screenshot in case the flaps or speed or weather etc are influencing this or is there something im doing wrong?
also sometimes ill be cruising and the plane will be slightly pitched up. ive come across a thread regarding trim but trimming up or down doesn’t seem to do much
sorry i tried to quote all your comments but i don’t think that worked out as planned!
i was flying at 9000 for quite a while before this happened. i was advised not to exceed 210 knots by atc, when i reduced speed the bobbing started. could it be because im going too slow although thats the max i was instructed to fly?
can i clarify what you mean?, sorry. flaps up as in they should be on 0? and spoilers up as in on flight or off? i don’t think theres much difference between off and armed - only when the plane touches down the spoilers will deploy? (correct me if im wrong)
i do think it was the fact i was going too slow, and the a/p kept increasing power to try maintain my altitude hence the plane was bobbing up and down. are ATC aware of this kind of stuff? the last time i responded unable i was told to follow instructions!
Yeah your probaly correct in that you were too heavy for speed so the A/P keep trying to correct it so it was moving a lot. ATC is not aware of this as approach normal cant ser the airplanes. I would just circle around for a while then land when lower on fuel and weight
