IO540 - yes I agree. However, that was not the point being debated. The question was if you could do the same flight to the CIs VFR or IFR airways which would you choose and why?
Bose orginally was saying he flew airways for better fuel management and better routing. He then said it was for a higher routing to extend the glide distance over the channel, but this was a side effect not an intention.
I was wanting to understand on a short hop such as this IF you could fly the same route VFR why you would elect to go airways.
If you have been following the thread you might recall it all started because the view was expressed that you shouldnt "file" IFR in VMC OCAS because you perceived it would prioritise the service you would get over those "filing" VFR.
