DTW High Speed/low Speed Track, What Is It?

Tue Aug 01, 2006 10:40 am

I am sitting at my house and listening to DTW radio traffic on my scanner. I recently programmed all of the DTW channels (I am now hearing things I have not heard before) and I frequently hear someone talk about entering or exiting the low or high speed track. It sounds like they are talking about cars and trucks, not aircraft. What is this? Is it the airport? or do I have a channel wrong.

Here in LAS they routinely tell planes to take high-speed turnoff so and so if able upon landing. It is a reduced angle turn off the runway as opposed to a typical 90 degree turn as an example.

Go to

and download the Airport Diagram (on the right side of the page). I don't see that the intersections are labeled "high speed" or "low speed" but the diagram might give you a better idea of what is happening.

Also look at the procedures down at the bottom. Depending on what freq you are able to scan, these might help you figure out what they are all talking about.

They are refering to high-speed turnoffs for aircraft. They are taxiways that are set diagonal to the runway instead of the normal 90 degrees. These allow aircraft that are traveling at a higher rate of speed to exit the runway more quickley. Maybe there is an aircraft on short final and if they take the 90 degree turn they will have to slow down to under 10knots and that will force the aircraft on short final to go around. Many major airport have thes type of high-speed turnoffs.
