BAe 146-100 is right. They do put max power on and hold it for what seems an awfully long time. On that particular day it was the 5th 747 to t/o in the 1 hour or so that I was there. The other 4 took off with an initial roll before hitting t/o power. The PIA gave it a real smoker before letting off the brakes and inching away. By the way, BAe 146-100, i've flown on numerous occasions on your type and find it a nice safe plane to fly on. The only problem is the cabin air. It always seems less clean somehow. Is that a design limitation?
