Now that the design has reached the preferred VFR spec I think it is prudent to consider the IFR version and so a weather radar will be needed and traditionally this is bolted on the front but lets' look at alternatives. It's sunshining outside but I have the uneasy feeling that IMC conditions will occur sometime in the future. Then there is the twin pitot tubes to think about and the advanced instrument panel which might require a wider cabin.
The boss, the skinflint with the bulging pockets, has thrown in his pennyworth (yes, that's all he's going to commit himself to) and suggests passenger steps for his VIP ladies who more often than not wear tight skirts and have difficulty getting in and out. He hasn't set a limit to the costs so pruedence is required here.
