Example: Pilot A takes off, flies to TOC. Hands controls to Pilot B, who flies a 3 hour cruise. Pilot B then takes controls, flies the approach and lands.
Pilot A P1 = 1 hr
Pilot B P1 = 3 hr
Anybody agree?
Agree too, but it is only legal if pilot B would otherwise be legal to fly the whole flight (including TO and landing). So if B is out of currency, for instance because of the 90-day/3 landings rule, this would not be legal.
Also, pilot B has to be "in command", not just "in control". If, say, a weather diversion is needed and it's pilot A making that decision while B is at the controls, well, you can't claim that B is "in command", can you?
I regularly fly with non-pilot passengers. They may be temporarily "in control" but I'm the one who is "in command". Never mind that these passengers don't even have logbooks.
I do not understand that correlation. PIC is PIC wherever you fly. What has the US got to do with it..
Under US regulations there are a few situations where two pilots, and sometimes even three pilots, can all log P1 simultaneously. I don't recall the exact situation but I think one case is where a post-PPL student (CPL, say) is under instruction. Both the pilot and the instructor can log P1. But do NOT take my word for this - somebody from the US can advise?
