Don't usually ask too many questions around here but this is one of those obscure things that has been nagging at me for some time.
Over the years I've noticed that with regard to ground spoiler deployment on landing, certain Boeing aircraft have curious properties. On the 777, for example, (pardon my no doubt incorrect nomenclature) the #2 outboard spoiler panels have a more shallow angle than the other four.
And on the 737 classics, the first two panels have the same setting whereas the last two panels have full deflection. The 73G models have an even more unusual arrangement where the last outboard panel is standing all tall with other panels recessed.
Surely there is a rhyme and reason to this but for the life of me I can't guess what it might be. Can some of you more in the know folks please shed some light on this technical oddity?
