Yes, one can fly raw data down to minima, but is that always the safest course of action?!
The reality is that flying with reference solely to 'raw data' (
nearly always) removes some element of 'spare capacity' from the PF, and invariably ups the workload / monitoring task of the PNF... these two facts alone would evidently reduce the overall level of safety.
And do trust me when I say that if / when you
it up, your company / bosses (
especially so if you're working in the Middle East) will not be sympathetic that you were 'practicing your raw data skills' and / or trying to save 2s6d of fuel (
by Spitfiring it on from 300 feet) and such activities are likely to result in 'tea & biscuits' and / or maybe even 'Johnny Out The Door' (
with a bad Reference, or maybe none at all) ?!
And knowing this is called 'Experience'!
