Logging IMC when not current
I'm not sure if this is the correct place to post this question, but I think it will be the place most likely to find someone able to give a good answer.
I am a CFI, but not instrument current. I went flying today in IMC with an instrument rated and current private pilot friend of mine. We took turns flying, any other day we would either just split the time or call it an instruction flight and both take all the time and log his time as dual given. Today was different though being in IMC.
Can I log the IMC time and the approach (and count the approach towards currency)? My argument is that I cannot as I was not legal to act as PIC in that situation. The argument could also be made that I am a rated pilot acting within the limits of my certificate.
I don't want someone to see actual time being logged without me being able to prove currency. Probably won't ever be an issue, but I still want to keep the logbook as correct as possible.
