No change to the controlled rest policy then?
CC are required to guard the one pilot while the other goes to the lav for a few minutes but when one pilot checks out for up to 40min (officially) replete with eye shades, ear plugs, blanket, the other guy is left unguarded on a one man show to do whatever he likes. One swing with a crash axe while he sleeps and it's goodnight Vienna. But I'm sure it'll never happen.
