Good evening guys and gals.
First I don’t fly either airplane, I’m a bus guy and I was having a friendly discussion on a FB group about the max speed allowed below ten, now someone brought up the scenario were a 747 and 777 at MTOW has to fly faster than 250kts after clean up below ten. I have never heard ATC approve a clearance like that before and I know that FAR 91.117 states no aircraft will fly faster than 250 below ten “unless authorized by the administrator” so my question is, are some US cargo company authorized by the administrator for this? Or is there another FAR that allow you guys to fly faster below ten when heavy? Or do you guys never takeoff at MTOW?
Again, I am clueless about both aircrafts and their operations and I appreciate the clarification.
Hope everyone is well
