FAA speed restrictions

[ikaro]

I have a question about the FAA issued 250kts below 10000ft restriction. In the FAR 91 it says only the administrator can change this, then, can I accept a clearence to maintain 280kts at 5000ft given by ATC?¿

No you cannot, not under any circumstances. If you could it would state "unless otherwise authorized by ATC."

Th only exceptions are listed in the regulation, such as heavy takeoff requiring greater than 250 once cleaned up. Some operators take that interpretation; some don't.

Isn't that only valid as long as one is over land or within the 12 miles zone along the coasts of the US? I thought over international waters ATC can issue speeds greater than 250kts below 10.000ft.

Thanks that´s what I thought but the captain yesterday didn't agree and accepted that clearence :ugh:

The regulations suggest that is correct

§ 91.101 Applicability.
This subpart prescribes flight rules governing the operation of aircraft within the United States and within 12 nautical miles from the coast of the United States.


in same part of regs

§ 91.117 Aircraft speed.
(a) Unless otherwise authorized by the Administrator, no person may operate an aircraft below 10,000 feet MSL at an indicated airspeed of more than 250 knots (288 m.p.h.).

... etc

And, the regulation basically allows the pilot to go fast beyond 12 miles unless ATC slows him down.

But, this is at the edges of the regulation, so to speak.

"...no person may operate an aircraft below 10,000 feet MSL at an indicated airspeed of more than 250 knots..."

...but not to worry, it would be OK with the FAA to do 280 knots at 5000 feet AGL at places like mile-high Denver; 8,300' Bogota; 9,200' Quito; 13,300' La Paz... :ok:

At one time at least, departures out of KIAH were procedurally authorized higher speeds below 10,000'. We'd depart on 15R and accelerate to 300K for the climb-out.


Yes, I remember that. Quite a bit of fun taking off south, in the 727, and by the time we would turn around and pass the north side of IAH we'd be doing close to 300 kts. After the controllers got use to us, we'd be given around a 180 turn to the north, which allowed me/us to complete the turn within the airport boundary, on southern takeoffs.

As this was usually the last stop of the day, this meant we could get to happy hour quicker. :p

But last I heard, that special procedure was canceled years ago. :(

Never the less, it was fun while it lasted. :ok:

Yeah, it was fun coming out of IAH. ALPA raised a fuss saying there was no data on bird strike damage at speeds above 250. As if bird don't fly above 10,000 feet. I figured they were worried about less block time cutting into their pay.
