In the UK there are many single pilot aircraft operated by two crew under the terms of the company's AOC
I fly a King Air and all our public transport flights are two crew.
So depending on where you fly the answer is yes (however both pilots must hold the type rating for the aircraft in question).
The really bizarre thing about this tho' is that you don't need an MCC to fly under these terms.
It is all a matter of agreement with the CAA
Oops, I just realised that the original question referred to flight time on a single so the chances are .....NO (I think)
