Ok i love the PMDG NG 737. I have the 800/900 series. Basically am having problems with N1%. I put in my gross weight and everything all correct, then the FMC directs me to the N1% limit page. Because the Gross weight has calculated my N1% Take off limitation for N1% lets say its clalculated 97.5%. It sometimes feels that its calculated it wrong. Like i was doing a flight today and i was at bristol EGGD (DEPARTING), and i nearly over shot the runway because i didnt have enough power and thrust to cover, because I was limited to 98.8% N1. I was just wondering can i change the N1% manually to a higher number so this dosent happen, or can i even turn it off? It also happend in Morroco it limited me to a low N1% and i nearly overshot the runway, i was even pretty light around 130000 IBS gorss weight. And im quite sure the NG737 isnt that underpowered! :( Cheers, Wowk!

98.8% is a high N1 for a TOW of 130000 Lbs (59000 Kg), and should be more than enough even in short runways.When you say "I nearly over shot the runway" you mean that you reached Vr with almost no runway left or that you were not able to get the plane airborne untill the very end of the runway ?What about your flap setting and your elevator trim ?

I agree, the N1 figures mentioned are more than enough for those take-off weights. How about joystick settings, are you sure you are are getting full aileron deflect?
