N1 % different between decent and ground position

[Guest shaheedan]

Hi all,Is this situation normal,1. during at ground, mimimum N1 21%, full trust during take off 96% only ?2. during decending, minimum N1, 34% which can cause speed more than 250 Kts especially on of below 10,000 Ft,I have to deploy a few degrees of spoiler to reduce a speed which i can see in the real aviation, i set V speed during decent at -1800is this normal in your all situation ?using CH sim yokeintel P4,1.6Ghz,640GB SDRam,D845HV intel motherboard,Ausu FX5200,128MB

Yes, above about 20,000 ft the idle N1 is about 40% and on the ground it is about 20%. I don't think this will cause you to speed up, since this is idle at that altitude. You must remember the 737 is a slippery plane because its small and doesn't weigh much. You would have much better control over the speed on larger planes like the 777, 747, etc.Nick B.Continental Airlines Virtual 737NG Pilothttp://www.precisionmanuals.com/images/forum/800driver.jpg--AMD Athlon XP 3200+ @ 2.2 Ghz (Equal to 2.8 ghz)400W Power supply3x 80 mm Case FansSoyo VIA KT600 Dragon PlusnVidia GeForce FX 5200 128 mb2 x 512 PC400100 GB Western DigitalMicrosoft Sidewinder Precision 2

Please keep in mind that in the real world full takeoff thrust is rarely needed or used unless conditions warrent. On descent the air flowing thru the engine will cause the rotation, refer to N2.Best Wishes,[h4]Randy J. Smith[/h4][h3]P M D G's 747-400[/h3][h4]coming to a runway near you[/h4][/font color]Caution!
