So this morning the stumble button brought me to the following link that I am assuming is planned as an advert or from an advertising shoot. I paused to enjoy the scene for a moment, before pondering a question.
I am presuming the model is standing on an area of the aircraft that is suitable for stepping on, but she seems to be wearing heels of some sort which would exert far greater forces onto the surface beneath them due to the smaller contact surface area. Are the step areas designed with occasional heel wearers in mind? I would guess that in this case it wouldn't as I could only imagine anyone to be up there for maintenance, and heels aren't exactly practical shoes for that work. But in the case of low wing aircraft 2 seats and larger where you need to step onto the wing to board? Is it expected that occasion passengers may be wearing heels?
As a followup, are areas immediately bordering the stepping regions reinforced to a degree to cope with the occasional misstep, or are inspections required when someone treads outside of the area regardless of by how far or how heavily?
