bilookhan 3 Posted September 14, 2013 Share Posted September 14, 2013 Hi Its me again. I am coming across a bit different issue but on the same route that I am planning CYYZ-> VHHH polar flight: TONNY2 TONNY YEE J556 LOYED J556 YYB 5500N07700W 6000N07700W 6500N07700W 7000N07400W 7500N07000W 8000N06000W 8600N04000W 8700N02000W ABERI B934 BINTA B934 PETAG B480 BG B480 OSNAR B480 BRT G490 SERNA A310 POLHO G218 TMR B458 WXI A461 LIG R473 NNX R473 WYN W18 NLG W23 ZUH R473 SIER (the route has been taken from flightaware.com) I am basing my flight on PMDG 777-100LR template. The process of building routes is pretty standard and straight forward that I am following: Input flight details with payload, cruise speed and fuel reserve required, then input and build manual route and assign ETOPS from suggested airports. When it comes OFP and ATC readings I am getting strange results for initial climb altitude and step climb altitudes. Here is what I mean: AC015/ACACANADA OFP 1 A6-EWB/B777-2LR GE ROUTE: (MANUAL) DEP: CYYZ/YYZ 05 ELEV 569 FT CRZ SPD: M.84 TTL G/C DIST: 6783 NM ARR: VHHH/HKG 07L ELEV 28 FT INIT ALT: 17000 TTL F/P DIST: 7106 NM BURN ADJ: 104.0% TTL AIR DIST: 7028 NM AVG WIND CMP: TL005 K (Initial climb of 17000 feet) Then somewhere along the route descend from 35000 ft to 9000 ft then climb back up 37000 ft: B480 BEPLA 174 FL350 315/039 484 15 118.2 / 190.7 02 09:55 -UIII -54 516 2349 N5758.7 E10122.2 ...../.....

tcasclimb 0 Posted September 14, 2013 Share Posted September 14, 2013 Yes i notice this too, here is the ATC flight plan you can see it descend to 9000ft at BRT. (FPL-ACA015-IS -B77L/H-SDE1FGHIJ1RWXYZ/LB1 -CYYZ2205 -N0427A170 TONNY2 TONNY/N0421F160 V34 YEE/N0495F310 J556 YYB DCT 55N077W DCT 60N077W DCT 65N077W/N0482F330 DCT 70N074W DCT 75N070W/M084F330 DCT 80N060W DCT 86N040W DCT 87N020W DCT ABERI/K0880F350 B934 PETAG/K0880F360 B480 BG/K0890F350 B480 VELNA/K0885F370 B480 BRT/K0522A090 G490 CS/K0889F370 G490 SERNA/K0896S1110 A310 POLHO/K0898S1160 G218 TMR/K0897S1130 B458 WXI/K0903S1160 A461 LIG/K0901S1190 R473 NNX/K0898S1160 R473 WYN W18 NLG W23 ZUH R473 SIERA SIER6A -VHHH1502 ZGSZ ZGGG -PBN/A1B1C1D1L1O1S1 NAV/RNVD1E2A1 DOF/130914 REG/N702DN EET/CZUL0045 CZEG0231 BGGL0349 ULMM0557 UOOO0818 UNIT0845 UNKL0925 UIII0956 ZMUB1107 ZBPE1155 ZHWH1256 ZGZU1350 VHHK1448 RVR/75 PER/D RALT/CYSR UOHH -E/1650) Link to comment Share on other sites More sharing options...
tcasclimb 0 Posted September 14, 2013 Share Posted September 14, 2013 When i mouse over the airways on the map starting from BRT, the G490 from BRT to CS has a MIN and MAX altitude of FL100, before and after that the max altitudes are much higher. Could be a error with the navdata or some other real world restriction at the time the database was created. For now to get more accurate fuel calculations, just plot a direct route from BRT to CS and pick up the airway from CS. Link to comment Share on other sites More sharing options...
Checkursix 3 Posted September 14, 2013 Share Posted September 14, 2013 The Jeppesen enroute charts show an MAA of FL100 in the northern direction, and FL530 in the southern direction on G490 between BRT and CS. For your direction of flight FL530 sould apply, but it seems PFPX doesn't have or consider the different restrictions based on direction. Link to comment Share on other sites More sharing options...
