The B's used in corporate work in US, that I know about (say @15), are/were all SPZ 7000/7600 series with full glass both sides, IIDS, UNS1B+/D and etc. Top of the line with all capabilities used to the max. Corporate flying is what it is and the equipment made life far easier than, say, offshore or HEMS, etc. Comes with the territory. Can get VERY boring. VERY little challenge other than concerns about top execs throwing a fit over who knows what when it hits the present.
