The emergency brake has yet to be invented... however the parking break may be yellow or red depending on the type of aircraft.

No such thing, either in airplanes or cars. They are parking brakes. That being said, what are you talking about here? A 65 horsepower Piper J-3 or a 747? Most pilots of small aircraft use wheel chocks instead of parking brakes, since they will occasionally stick. You haven't lived until you have landed with one wheel not turning and going in all the resulting circles.

the pilots webpages and chat rooms talk about brakes, but never parking brakes. Sample comment from Downers Grove, IL:

Strictly speaking, there is no "emergency" brake as such but as mentioned, rudder pedal brakes and park brakes.

However...jets are slightly different.

A jet has a system that's called autobrakes. These brakes (simply) detect the pressure on the wheels and angle of the wheel bogies and when they sense the aircraft has landed, they apply automatically to slow it up.

Autobrakes have a setting, from 1 upwards, to set their intensity - obviously, higher intensities on short runways - and lower intensity, say, if there is a risk of dynamic hydroplaning.

However...the most extreme setting of autobrake is called "RTO" - or Rejected Take Off.

This setting is the closest to an emergency brake - and is set before takeoff.

In the event that something goes drastically wrong (usually engine failure) before the takeoff safety speed (which is the speed at which the plane is simply going too fast to stop), the pilots will close the power levers fast - and with this closure, autobrakes will apply in RTO setting - to apply maximum force braking to pull up in a rejected takeoff.

This is the only "real" emergency brake a plane has, and this autobrake/RTO system is limited to jet transports - a light plane won't have it!

There is no emergency brake in an airplane. The brakes are located at the top portion of the rudder pedals. There is, on some models, a parking brake, but there is no set color scheme for the control knob for it.

The differance between a parking brake and an emergency brake is that when a parking brake is applied it is applied "full on" whereas an emergency brake can be modulated or applied in varying degrees. And yes, many aircraft are equipped with emergency brakes. There is usually only one brake handle that doubles as the emergency brake/parking brake but some other aircraft have a separate handle. As the handle is pulled, or pushed as required, the brakes are gradually applied until they are fully activated at the end of the stroke.
"In using the emergency brake lever, slow steady downward pressure is required." ( from Learjet training manual)
As far as color goes, they are normaly painted yellow but I have seen them painted white, red or yellow with black stripes.

there is no "emergency brake"....could you imagine flying along and needing to use an "emergengy Brake??? they do however have a parking brake for when the need to keep the plane from moving at a terminal and it is white.

I believe they went with the sparkling puce color this season. You know I really preferred with they used the sating sheen old world chartruese lat season. But alas nothing stays the same does it!
