May I ask for some advice?
There are some CDRs that can fall into more than one CDR category. I have come across one which is both a CDR1 and CDR3. How do I flight plan this route? Is it even possible?
A (plannable) CDR1 seems to be mutually exclusive from the CDR3s, which are 'not plannable per se' and used tactically by ATC, so I'm confused.
The supreme irony of it all is I don't even want to use the airway as it's an upper and I'll be too low, but the direct routing I'd hoped to exploit is only available when this particular upper airway is also available.
And even this is only because my original route didn't comply with the RAD, the RAD-friendly alternatives go somewhat around the houses and add a few too many track miles.
Any insight gratefully received. Ta
