Wodka,
Are you in reciept of an IFR clearence?
If so, I would say yes, you are flying IFR, IMC, VMC has nothing to do with it.
Agreed the 'instruments' time setting up for your run in is a bit much to log as IFR, I fly 'IFR' in that case many times at work, though I am still operating under VFR rules, with a few dispensations
You can cross class A airways VFR so perhaps the arguement for IFR only isnt as solid as it might be.
Its one of those things, what does your CP say?
Regards,
BRS
