Interesting discussion. Some facts: 250 kts = 422 ft per sec. 300 kts = 506 ft per sec. Thats a difference of 84 ft/sec. If one sec is all I need to miss another aircraft by 84 feet then I can live to talk about it.
Impact forces increase with the square of speed. Just an increase of 10 kts can produce considerable greater damage.
The integrity of windshields, engines & leading edge devices connot be guaranteed above 250 kts below 10,000 ft.
In 1998 a B-727 in Texas climbing out of 6000 ft at 280 kts hit some geese and had about $5,000,000 damage done to the aircraft. Engines 1 & 2 had fan damage.Vibration was so high, comm on the flight deck was almost impossible. The radomewas gone alone with the antenna. LE of both wings damaged. Kruger flap on right wing was punctured as well as the wing. F/O's pitot tube gone - no air speed.
Still want to fly above 250 below 10 ????
Ignorance is not only bliss, it's STUPID !
