Brian, I am not quite following you here.
On logging time, I know the answer for the PIC pilot is no.
61.51 (e)(1)(iii) When the pilot ... acts as
pilot in command of an
aircraft for which more than one pilot is required under ... the regulations under which the flight is conducted ...
What question are you answering here?
But then I made the mistake of actually reading the 61.51(e) and started doubting, section iii) specifically. Under the part 61 regulations and the way the flight is being flown, two pilots are required, one to operate the controls and one to be the legal PIC.
Well, the person under the hood can be the legal PIC. In that case the safety pilot would be SIC because he is required by 91.109(c).
Under the regulations, the flight could not be operated if the PIC pilot is not on board.
Obviously a PIC must be aboard. But just WHO is the PIC? It could be either pilot.
I know the answer. But I don't know why, if the PIC pilot is required by the regulations to file and fly within the IFR system, he is not a second required pilot for the flight.
I will confess that I have lost the context of this thread. I will assume that you are talking about needing a safety pilot and how each pilot can log the time.
Two sections of the FARs are involved here. 91.109(c) is the regulation that requires a safety pilot if the other pilot is operating under simulated instrument conditions. Simulated conditions are any time a view limiting device is being worn regardless of whether or not the flight is being operated in the clouds.
61.51 deals with how the flight can be logged. If the safety pilot is the legal PIC, he can log the entire time he is sole manipulator of the controls as PIC, and the safety pilot logs SIC because there cannot be two legal PICs at the same time. And the SIC only logs the time the other pilot is wearing the view limiting device.
If the Safety pilot is the legal PIC, then both pilots can log PIC for the time the other pilot is wearing a view limiting device. But this is one instance where the legal PIC cannot log the whole flight.
When the flight is operated in IMC conditions, and the pilot manipulating the controls is not instrument rated, the safety pilot must be instrument rated and file for IFR as PIC. And as long as the other pilot has the view limiting device on, both pilots may log PIC. But operating in the clouds with a hood on is kind of pointless so when he takes it off, the safety pilot is no longer required. The sole manipulator of the controls may still log PIC, but the legal PIC may not because there is no provisions in 61.51 for him to do so.
It's kind of convoluted, but that is the way it is.
