Am I right in thinking there is a difference between the two?
Recently I have been trying to study/brush up on the various systems of the 737.
In particular I have been looking into the minimum maneuver speed (.3G maneuver margin) on the speed tape which I have learned will move depending on where you tell the FMC the C of G is i.e. the more further act the C of G the lower the min maneuver speed becomes, would I be right in thinking that this would be changing the wing loading of the wing? More aft C of G means more overall lift as the tail plane is not trying to counter nose down tendency as much? So the min maneuver speed is effected by wing loading and NOT G-load? In the FCTM it says the minimum maneuver speed is NOT effected by G-load.
In relation to the min speed (red and black pole), I’ve read that this is affected by G Load, so if I start pulling some tight turns hence increasing the G Load, the min speed bar will come up a lot closer to my current speed, i.e. aircraft weight is artificially being increased and so I need more lift and speed to maintain it in a turn, Correct or not?
In relation to the speed brakes, its says
In relation to the MIN MANEUVER SPEED: reflects the effect of extending the flight spoilers. (Why is this, do and if so, why do flight spoilers/speedbrakes effect the min maneuver speed?)
In relation to the MIN SPEED: reflects the effect of extending the flight spoilers(why is this, g-load or wing loading?) and also reacts to wing loading (what does it mean by wing loading, G-load or weight of the aircraft?)
