September 1, 201114 yr Since you are getting a rise in N2% sounds like something with the packs are not set right. Steven Herzberg, "I rather be flying"
September 1, 201114 yr Typically the cause of low N1 during start is a pack being on. Maybe if you posted a screen shot we'd get a better idea of what's going on. Tom Landry
September 1, 201114 yr Are you trying to start with the the APU or engine 1. If engine 1 you probably don't have enough bleed air, bring N1 up to about 40%. Make sure the packs are off.Tom beat me to it! :-) George Morris
September 1, 201114 yr Author all two packs are off,engine ignition is on GND,i have try of everything!!!i now retry to restart the airplane and i will get a screenshot of the situation
September 1, 201114 yr Have you forgot to raise your "Engine start Levers" or not?....../ Leffe Leif A Mikkelsen **********************
September 1, 201114 yr Author that's the overhead panel and this is the efis paneli don't know if you can see but N2 percentage is on 18.1 and N1 is on 31%see what's wrong please
September 1, 201114 yr Your packs have to be off. Also as said above, did you raise your start lever, when reaching 117-18%/ Leffe Leif A Mikkelsen **********************
September 1, 201114 yr load the 737-800 from the 'Free Flight' menu once loaded, open the CDU, menu, PMDG SETUP, PANEL STATE LOAD, select NGX CLDDRKclick EXEC at OVEHEAD BAT to ONSTANDBY PWR to AUTO START APU (left click twice) when APU GEN illuminate, set both to ON APU BLEED to ONENG 1/2 BLEED to ON L/R PACK to OFFISOL to OPEN R ENG START to GRN at THROTTLE at N2 = 25%R FUEL lever to IDLE at OVERHEAD ENG GEN 2 to ON repeat for ENG 1 good luck, Matt
September 1, 201114 yr Author the engine start levers have to be rised on 25% of N2,so i should not do it up to that moment..but a've tryed aniway and it doesn't works
September 1, 201114 yr The packs aren't off as far as I can tell, you've left them on auto, move them to the OFF position. Andrew McCluskey
