The green band is ‘on speed’ (“Approach Reference Band”) for “appropriate range of approach AOA for a Vref + 5 approach.
It’s Vref +7 in your example even at the higher AOA limit of the ‘on speed’ range.
The green band band covers a significant speed range and isn’t as accurate as military AOA ‘on speed’ green donuts. Because of that range/inaccuracy (roughly 2.5 units) it’s not used as a primary performance instrument.
