TWRTrainer / Similar Runways

[Christopher Denton 1312811]

Hello!

 

I am currently creating an airport file for KCHS (Charleston AFB/Int'l), as we are switching some training to this airport. I've created the airport file by capturing necessary intersection points in VRC; however, I have an issue. KCHS has a runway 3 and a runway 33. When I command SWEATBOX aircraft to taxi to either, they get stuck in a loop between the two. Not quite sure what is going on, as any other runway, the aircraft can find a path from pointA to pointB. A keyword search in this forum didn't return any results.

 

Any help?

 

Regards,

Christopher Denton

And what command & arguments are you using?

[Christopher Denton 1312811]

The .air file loaded contains just one test aircraft. .air file is next on my list.

 

N470ER:C172:P:V:KCHS:KCHS:1500:CLOSED TRAFFIC:/v/:1200:S:32.89952:-80.03279:0:0:0

 

Unpause.

Then, I have to get N470ER moving before I can type another command, so:

taxi G2 G A 21

 

Next, add an aircraft at the terminal.

add i l j @T1

 

Select that aircraft, tell it to taxi to Runway 33.

taxi B C 33

 

It will taxi off the ramp, and start traveling towards taxiway A, then turn around at A.

 

If I tell it to taxi to Runway 3, I'm told that taxiway C and Runway 3 do not intersect, which is a different problem I can fix.

[Christopher Denton 1312811]

Sigh.

 

I fixed it. False alarm. It was a copy/paste error, resulting in an erroneous coordinate. Thanks for looking at it.
