why dont they remove one pilot and just make the aircraft to accomodate only one pilot so that the front area decreases and the aerodynamic advantages can be gained to some extent besides they are anyway being certified for single pilot operation…
Although it would never happen, you have to admire the simplicity of this question. It does seem to have some logic behind it on the face of it. If only one pilot, then you need only one seat. Seems to make sense. It worked on the Dragon Rapide.
SP ops, especially with rather fast turbine engined aircraft, carrying pax, flying in busy european airspace is probably a decreasing business anyway, certainly on CAT. Whether it has 1 or 2 engines is largely irrelevant from that point of view.
