Heavy means that is a very large airplane. A heavy airplane weight more that
255,00 pounds.

Let me put a little background behind that.

Air Traffic Control is responsible for keeping a certain amount of space
between each aircraft. The exact amount of space varies with a bunch of
different factors, but it's typically several miles.

Airplanes create an invisible wake in the atmosphere, just like a boat
creates a wake on the water. And, just like the boat's wake, the
airplane's wake can be dangerous to other airplanes. Heavy airplanes
create bigger wakes, so ATC is required to give an airplane following a
Heavy some extra distance. ATC is supposed to know if a given type of
aircraft is considered Heavy, but as an extra reminder to controllers,
pilots of Heavy aircraft add the word "Heavy" to each transmission.

Aren't "heavy's" allowed to go faster under 10,000 feet as well?

Not generally, as far as I know. Section 91.117 makes an exception only if
a specific exemption has been granted by the FAA or the minimum safe
airspeed for an aircraft is greater than 250 knots.

No.

Isn't the limit 250 in CBAS regardless of altitude?

Ok. I must have missed the change to 91.117. Do you know when it was
changed?

This is the version of 91.117 I'm familiar with:

§ 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.).

(b) Unless otherwise authorized or required by ATC, no person may operate
an aircraft at or below 2,500 feet above the surface within 4 nautical
miles of the primary airport of a Class C or Class D airspace area at an
indicated airspeed of more than 200 knots (230 mph.). This paragraph (b)
does not apply to any operations within a Class B airspace area. Such
operations shall comply with paragraph (a) of this section.

(c) No person may operate an aircraft in the airspace underlying a Class B
airspace area designated for an airport or in a VFR corridor designated
through such a Class B airspace area, at an indicated airspeed of more than
200 knots (230 mph).

(d) If the minimum safe airspeed for any particular operation is greater
than the maximum speed prescribed in this section, the aircraft may be
operated at that minimum speed.

Just wanted to thank everyone for their responses. Quite fascinating
stuff here. Thanks again.

Also, I was watching United 93 and they kept using the term "squawk".
I looked it up in a few resources mentioned but since I have no
aviation experience couldn't quite grasp the meaning. What exactly is
a squawk and what is it's function?

And you can listen to this online!!??? Awesome. anyone know of some of
the better sites?

I posted the best resource for online ATC streaming. Did you miss that post

Peter,

I didn't miss your post. It said there were over a 150 options. I was
wondering if you could recommend a few. Or are they all the same.

Thank you for posting that information!
