I'm just getting started on my commercial SEL.

I've got 270tt and already meet all of the flight experience requirements for the certificate excluding the 10hrs of instruction in a Complex aircraft.

My question is regarding the following:
(iii) One 2-hour cross country flight in a single engine airplane in daytime conditions that consists of a total straight-line distance of more than 100 nautical miles from the original point of departure;
(iv) One 2-hour cross country flight in a single engine airplane in nighttime conditions that consists of a total straight-line distance of more than 100 nautical miles from the original point of departure;


Must these two flights be perfomed solo/PIC or as dual with an instructor?


If it is solo time, I've got it covered. I've heard conflicting info with some people saying that those flights must be with an instructor and logged as dual.


Can anyone shed some light?


Thanks
