In 135, I know you can only log PIC time as an SIC if you are the sole manipulator of the controls. This means manipulating the autopilot as well. However, if the aircraft is rated for the use of only "single pilot," then PIC time can only be logged while at the controls during the empty legs or Part 91 legs. Make sense? I have discussed this with my DO back in Sept. He was my check airmen for 135.293(b)

Now, that we all have put in our .02 cents I think sellener has a question. Check up on www.airmethods.com. To apply for an SIC position all you need are Part 135 VFR mins. only. Good luck.
