This is another JAA stupidity.
The military logs 'flight by instruments' whether simulated or actual, whereas the JAA idiots ask for flight under IFR.
So, on a nice blue day, fly at quadrantal levels above 3000' amsl on 1013, observe Instrument Flight Rules and you can log the time irrespective of whether you're under IFR or VFR in VMC!!
As an example - last time I flew a VC10 to Dakar it was under IFR throughout. But we didn't see a single cloud......Military 'IF' time was zero, under JAA 'operational conditions' I could have logged the whole 6 1/2 hours as 'flight under IFR'.........
Daft - but that's the way of the JAA!!
