From glancing at the bridge diagram, I figured there'd be no place for her to sit, hence why I asked about her standing next to Vash. I also figured there would be an office for her (in some dark corner :P) where she would spend most of her time unless she was needed. She can just grip onto something for dear life during evasive maneuvers.
