Verification error

I've tried to fix the route between LGAV and EIDW you asked for:

NEVRA UZ507 TSL UL617 MAKED DCT LONTA/N0450F340+ UL608 DOLEV DCT PETOV DCT GOLVA DCT LAMSI L604 RUDNO DCT MAPOX DCT RAVLO Y70 OTBED L60 PENIL UL28 LELDO M145 BAGSO

When I verify it using IFPS (http://validation.eurofpl.eu/) it comes up without errors, while vroute gives an error for airway L60.
Looking at the SRD for the UK it says RAVLO Y70 OTBED L60 PENIL UL28 LELDO M145 BAGSO (FL245-FL660). Also the description of L60 in AIPUK Enroute section 3.3 is consistant with the described route.

Perhaps vroute's verification system fails.

Hello Torben,

This is an issue that affects PFPX also in that there are split levels dependent upon direction of flight.

Between MOGMO and OTBED flight levels are restricted in the ODD direction between FL195 & FL230

EVEN flight direction is FL260 - FL460

With PFPX only the lower level is available.

I'm not sure if this an AIRAC data error or the application as I cannot access the airac data in these cases.

hello Stephen
I inserted the published route into PFPX and did the verification - no errors. I then inserted the route in IFPS, as I wrote - also the route came out as valid. That vroute validation returns an error seems to indicate a problem with vroute - not PFPX. At the flight levels in mention (FL300 - FL430) a westerly direction of flight is ok.

Regards
Torben

If I paste the route into the PFPX editor and validate at say FL360 then yes it does pass.

Constructing and computing a flightplan results in a descent to FL220 before OTBED and the validation fails.

If you look at the available levels in PFPX for L60 it shows FL190-FL230 between OTBED and MOGMO

I believe it is for this reason vRoute's initial check fails the validation.

This situation has been around for quite a while and as I recall Michal manually overrode the FL's for previous issues in Poland.

Yes, a descent to FL220 before OTBED would bring you in trouble. However, I wouldn't start my descent before SONEX, which is approx. 100nm before BAGSO. Depending on STAR you wouldn't want to be below FL80 at BAGSO and using a rule of thumb from FL360 to FL80 takes around 100nm. MOGMO is way to soon, I guess.
