My baggage volume comment related to the 109P width figure being smaller than the 109E. If the usable airframe interior was longer the volume might stay the same but be calculated from different dimensions [if you can still follow me!] .
I just hope that AW know what their selling and the customers understand them..... cos I am losing it!
I think we will have to await confirmation of those numbers because at the moment the overall interior of the Grand looks smaller than its predecessor and that cannot be right!
