OK (Thanks for the answers on the previous posts. I am getting ready to fly a LevelD NGX full motion simulator in 2 weeks and want to be as prepared as possible).I noticed (long ago) the 737 takes a long time to slow down. PDMG says it is a slippery aircarf - I agree.But I did some testing.At 5000' level with 15,000 lbs fuel 125,000 lbs ZF weight. It took 2 minutes and 2 secs to slow down from 250 kts to 200 kts. Then I started a 1200 fpm decent to 3000 ft and was at 260 kts at 3000 ft. This all was done with no flaps or speed brakes. Does this seem too excessive? I will verify these times on the full motion simulator - but what do you think? Oh one more thing. why is the mimimum N1 I can get 40%? With the throttles at idle I get 40% min, using F2 I can get 33% but it climbs to 40% quickly. Can this be my problem? Whatis the min N1 you get?
