The fact is singles do fly in the uk at night and in and out of tiny confined areas a lot of the time with ppl's doing the flying so to say they are more dangerous is daft there is no evedence !
PPLs aren't allowed to fly for hire and reward. Anybody else on board is simply a volounteer! As a professional, I have more respect for my own life than to sit in an R22 at night, in and out of a confined area with a PPL at the controls. Anyone doing that must be tired of living! But then again I was uncomfortable in a Wasp over the South Atlantic at night, out of sight of land and ships! I must just be a coward eh? But then I have managed to achieve a reasonable age.
As far as twins are concerned, yes they can be a little more complex. Try flying the Wessex! They are vulnerable to all the same accidents as singles EXCEPT engine failure/damage rarely requires an immediate landing!
Your chance of taking the wrong action in a twin is unlikely to change with more time in them, so
never make that assumption. (However many hours you have in your logbook, only the
next one's important!) Only strict adherence to quality training, combined with incessant 'rehearsal' will protect you. So if you haven't had quality training, and you aren't prepared to be meticulous, don't ever strap one on, because like anything else, in the wrong hands they will (and frequently do) kill.
