This route seems to be a case where the automatic routing engines have big troubles. I was not able to obtain any reasonable route using the usual tools and even using manual corrections I was not able to produce a good route. In the end I used the following which worked out very well in the air but I admit it is not elegant to have a VFR segment at FL230 in between:
WIK125030 DCT WIK125080 DCT WIK125130 DCT WIK125180 DCT WIK125230 DCT WIK125280 DCT WIK125330 VFR DCT DHE/N0200F230 IFR L619 PITEN Z998 RATMO VFR
Am I missing something? Any level up to FL250 would have been acceptable.
I get this using the autorouter engine with the DCT penalisation in the UK disabled (F200, I don’t have an aircraft model handy that does more):
EGPC DCT FORTY DCT VARUG DCT RUDOK DCT ALOTI DCT NIVUN DCT NORSO DCT KARLI P613 NUGLO DCT BAVIL DCT LONPA DCT ALASA P615 TUGDU M852 AMLUH L619 PITEN Z998 NISGA VFR EDAZ
Around 8% overhead
