I used routefinder to generate a flight plan. route finder flightplan: NAT: Eastbound track message identification is 75NAT: Westbound track message identification is 75Computed route from HEATHROW (EGLL, EG) to SAN FRANCISCO INTL (KSFO, K2): 41 fixes, 5131.9 nautical miles Cruise altitude between FL250 and FL350EGLL (0.0nm) -SID-> CPT (28.4nm) -UL9-> KENET (37.3nm) -UL9->BASET (47.2nm) -UL9-> DIKAS (106.3nm) -UP4-> EG190 (209.8nm) -UP4->EVRIN (229.0nm) -UL607-> CRK (300.8nm) -UN523-> DOLIP (430.9nm) -UN523->LIMRI (541.8nm) -NATB-> 51N020W (738.1nm) -NATB-> 50N030W (1124.3nm) -NATB->49N040W (1518.6nm) -NATB-> 48N050W (1920.6nm) -NATB-> NOVEP (1962.1nm) -NATB->YYT (2039.8nm) -J575-> LEXAK (2063.1nm) -J575-> YQY (2346.3nm) -J509->YYG (2473.8nm) -J509-> YQM (2534.4nm) -J509-> HUL (2670.5nm) -J509->PATTA (2744.1nm) -J509-> VLV (2796.4nm) -J565-> CATOG (2881.5nm) -J565->YMX (2943.9nm) -J513-> YMW (3012.4nm) -J513-> BOBRA (3036.7nm) -J513->SMARE (3104.3nm) -J513-> YYB (3157.1nm) -J500-> BILPA (3281.3nm) -J500->SSM (3359.2nm) -J140-> DLH (3685.2nm) -J32-> ABR (3954.9nm) -J32->DPR (4097.8nm) -J32-> CZI (4309.9nm) -J32-> BOY (4397.0nm) -J32->MLD (4594.9nm) -J32-> BAM (4818.8nm) -J94-> LLC (4899.1nm) -J32->FMG (4960.2nm) -STAR-> KSFO (5131.9nm) Details: ID FREQ TRK DIST Coords Name/RemarksEGLL 0 0 N51

Ms/Mr Nameless,Please sign your posts with your real name as per forum guidelines.Did you enter the NAT waypoints as 5020N, 4930N, etc. into simroutes.com? If not you will have errors in the .rte file you downloaded.A "DISCO" is not an error. It's just a message from the FMC that that particular part needs your attention and is common even in the real world. Always go through the flightplan to check for DISCOs before executing.Hope it helps,
