So I look around at nearby flights, and their cruising speed is like 400 - 500 knots which is normal. So then I try increase my speed to 370 knots. But it says I’m over speeding and I have to have my cruise speed below 300 knots?? Why??? I’m so confused because I always see others with their speed at 400 knots, obviously with no problems. And I’m stuck here doing speeds between 250 - 300 knots. Please help. My main question is: If above 30,000 ft, what are the overspeed rules / speeding limits? I usually cruise at around 34,000 - 36,000 ft.
I would love the help, Cheers.
