I know this is probably and more than likely asking a question in regards to basic aviation stuff that I should know but all the same, any information would be very helpful.
I have been recently reading up on the minimum speed (black +Red band) and the minimum manevuer speed (amber band) on the speed tape of the 737 NG in particular the 800 in case there is a difference on the other NGs, but I do not believe there is.
From reading it, my understanding is that the minimum manevuer speed (amber band) gives you a .3G margin in 1G straight and level flight and this will decrease with altitude to adequate etc but it is NOT vary with G-load.
In regards to the minimum speed (black +Red band) it says that it DOES react to an increase in G/wing loading, so if I increase the G for example in a steep turn it will start to increase or get bigger on the speed tape.
One of the things I am confused with this is that both will reflect the effect of extending the flight spoilers.
I am not trying to say that is wrong but I thought the spoilers would only increase the wing loading so hence only the minimum speed (black +Red band) would be affected. How do the flight spoilers effect the minimum manevuer speed (amber band) if is not affected by G/wing loading (apparently!), see next paragraph...
In relation to a more rear C of G, this should decrease minimum manevuer speed (amber band) which to me would suggest that the meneveur speed IS AFFECTED by wing loading. Because with a more forward C of G, the tailplane has to produce more downforce hence the main wings have to produce more lift at a particular AoA so hence more wing loading which increases the minimum manevuer speed (amber band)
Any help or info would be greatly appreciated.
