The "
Administrator" delegates his authority to FAA Inspectors, or ATC controllers, etc.
ATC has the authority to waive the 200/250 limits when aircraft requires higher speeds.
It implies that the aircraft requires higher speed
as minimum speed.
We advise "departure control" on initial call of our speed requirements.
Funny is that when ATC knows we are 747, they clear us "speed at your discretion".
