Logging time 'on top'
If you were flying on top of an inversion layer/cloud layer, with negligible ground contact, IFR, but your basic flying was with reference to the visual horizon not the AI, would you log that as instrument time? After all, it's not 'by sole reference to instruments', but an airline pilot friend of mine flying IFR in various weather conditions logs every flight as instrument time regardless of whether it's in VMC and I gather this is standard practice...
I ask because if I can log such flights I'm under-recording my instrument time - I would only log time actually in IMC or simulated IMC.
The ANO is not much help (just says you must record 'instrument flight' but the latter is not defined, that I could see).
