    In the Air Force Combat Comm Groups/Squadrons we had mobile TACANs, and we moved them all the time. Don't know if they still have that equipment now though.

    Moved them on trucks?

    Transported them on trucks, plane, whatever. They sat on a tripod and we had the monitor run over to the tower, mobile or fixed. Like this or similar:

    Is your question do they mount them on a truck? I guess they could but every one I saw on deployments and/or exercise was set-up on the ground. Just my experience though, doesn't mean they weren't set-up on trucks.

    Not really a question. Just pointing out that mobile TACANs had been mentioned some time ago.

    Sure, you can mention them again. It's still a semi-free country. Just looks a little silly to mention them again while quoting the guy who had previously mentioned them.

    Based on observed behavior I'd say that looking silly just isn't a consideration for you when posting here.

    86 seconds to touchdown and they're still at 10,000ft... Crazy.

    I'm still waiting, but haven't felt silly yet. Why did you read it then?

    One of my favorite stories was told to me by a an ex-F4 pilot. The had been tasked to play the opposing force attacking the US coast line. They were to approach the coast at maximum speed and a flight of F-15's was to intercept them.

    So then general idea is you have flight of F4's approaching at Mach 2.x and a flight of F15's approaching from the opposite direction at Mach 2.x. So they have closing speed of something a bit less than Mach 5. Of course as the exercise is planned to go the F15's simulate a missile launch at the F4's. After the missile launch the F15 ground controllers vector the F15's into a hi-G Turn, I assume something like a left then right turn, that positions them directly behind the F4's in perfect position for another missile launch at the F4's.

    At the debriefing after the exercise both the F4 and F15 pilots inquired with the ground controllers as to how they were able to vector the turns so well as neither the F4 pilots or F15 pilots had ever seen anything like it. As you can images the F15's had to start their turns while the F4's where still well ahead of them to make this work. The controllers responded, oh, we have been practicing that for the chase planes for the Space Shuttle.

    That may be your intent but you're coming off as silly.

    I'm serious that your posting history indicates you are silly. You may not agree. I am certain many agree with me.

    Why not just spin the OBS to find what radial takes you to the station. I can see this method if one was trying to intercept a desired radial. What am I missing?

    The point was to intercept a radial, not to go direct to the station. If ATC tells you to join an airway or a radial, they don't want you to go to the VOR (they may start asking about the accuracy of your instruments). Again, just as everything else with tracking courses, you try a heading that you think will put you in the right direction. You fly it for a short time and see if the needle behavior confirms that the guess was correct (the needle should be trending towards center). If it's wrong, adjust your heading and try again.

    Once it gets close to center then pick a heading that you think will keep you on the radial (usually it's close the the radial or its reciprocal). Again, you watch the trend of the needle, if it starts to swing away, pick a new heading and try again. What you don't want to do is just spin the OBS and center the needle or just keep turning right or left to chase the needle.

    Agree. Referencing the video I did mention that intercepting a radial, the video made sense. But what got me crossed it seemed like the video was trying to describe how you know which way to turn to head toward the station. Now I see that the radial he had selected was the one ATC instructed to intercept, then the video made sense
