Is there a way to restricting "chase view" to aircraft in the air?

I like to look at the AI aircraft during my flights by using the "chase view" option, ctrl-w (shows one plane at a time, but you can see them all individually by continuing to press ctrl-w). But, it shows all the AI aircraft, including those just sitting at gates. This can be a lot if you are in the vicinity of a major hub, such as KORD or KDTW, at the "wrong" time of the day.Is there any command that can be entered into the fs9.cfg file (or anywhere else), that restricts the chase plane view to just aircraft in the air?Thanks.
