I think you need to ask a very much more specific question.

Without the stabilising surfaces, the aircraft would spin out of control. That is how they contribute to stability and their main effect on performance. This holds true for most aircraft and is not specific to the 777.

By the sound of it, I would suggest dropping the 777 for now, even if it is a favourite of yours, and focusing more on general handling and stability. You will have the opportunity to specialize later. Then you will be able to ask the question with a lot more precision as well.

Regards,
Fred



I thought I was doing good trying to avoid those airport hotels... and look at me now.

As Mr T says, it's a very broad question.

However, in general, FBW aircraft can get away with a smaller empennage since the FBW can help by making frequent, very precise corrections even with limited surface area. Smaller empennage, in general, means less drag.
