Descent to FL190 during CRZ? (not on airway)

Since France started becoming a Free Route Airspace and removing certain airways, theres been an issue on Simbrief when flying westbound from Switzerland to Spain, where Simbrief will plan a descent to FL190 at certain waypoints (in this case LERGA) during cruise.

  • These points are not on airways
  • These point are not flight level restricted
  • These points are mandatory routing points for when crossing that section of France. You can check the Eurocontrol RAD Annexes yourself.

Here is the ICAO flightplan of one of the routes I am talking about:

(FPL-DLH506-IS
-B748/H-SDE3FGHIM1RWXY/LB1
-EDDF1330
-N0515F270 ANEKI1L ANEKI Y163 HERBI/N0513F290 Y164 MOPAN DCT LUTIX
N869 BENOT DCT NEMOS DCT NINTU UN869 REPSI DCT LERGA/N0482F190 DCT
MINSO DCT NARAK DCT AGN DCT MAQAB/N0514F300 DCT TIVLI/N0518F290
UN869 ZAR UZ245 CJN UN10 SVL UN857 IBALU/N0521F310 UN857
TERTO/N0528F300 DCT LIMAL/N0529F320 UN873 ASEBA/N0528F340 UN873 NTL
UZ14 XOBOB UZ21 UGUDI/N0524F360 UZ21 VUNOX SANPA1A
-SBGR1028 SBKP
-PBN/A1B1D1O1S2 DOF/230120 REG/DABYA EET/EDUU0015 LSAS0022 LFFF0033
LFBB0054 LECM0115 GMMM0215 GCCC0304 GVSC0429 GOOO0528 SBAO0646
SBRE0737 SBBS0932 SEL/BRDH RVR/075 OPR/DLH PER/D RALT/GVAC SBFZ
RMK/TCAS)

As you can see, for some reason simbrief has me at FL190 between LERGA and MAQAB. Ironically, the icao flightplan as it is will make eurocontrol spit out a bunch of errors. Remove the FL190 step descent, and eurocontrol has no issues at all.

Hi, thanks for the report.

This has been a long standing issue. The reason is that the RAD Annex 3B still lists a lot of these DCTs as capped at FL195.

Until now I’ve been manually correcting them when I see them, but clearly that isn’t enough. I’ve now set it to ignore all French DCT restrictions that are capped at FL195. That should fix the issue for good.

Best regards,
