There seems to be this yesteryear opinion that the job, single pilot, is 'dangerous', but within the bounds of the training and the SOPs, even the night work to Barra is fairly straight forward.
I'm not suggesting that single pilot ops are "dangerous" per se - just that they ARE undoubtely more risky than two pilot ops.
If that were not the case, why do we need two crew on a B737/A320 which has an even better APFD and nav suite than the Islander?
Two pairs of eyes and two pairs of hands are safer than one. Always have been and probably always will be.
