Teacherjh,
AIM is not gospel, and although it represents distilled (good) judgement, it should not =replace= judgement. Of course not. But there was no judgement in your post. -- Thomas Borchert (EDDH) |

No, I only squawk on the ground. That way no one knows where I am ;-).
Guess it is old age catching up with me, huh? "Steven P. McNicoll" wrote: "Ray Andraka" wrote in message ... I put mine in the alt position after clearing the runway. That way, next time I turn on the avionics I'm not squawking an IFR code that might be in use. I assume you meant to write "stby" in place of "alt". -- --Ray Andraka, P.E.

Sure there was. I made the judgement that it was better for me to briefly not reply to a ping than to reply inappropriately as I was switching numbers. Jose -- (for Email, make the obvious changes in my address) |

Doesn't matter as the software in the radar is calibrated so as not to display a code on the airport. We have ours set so no transponder returns show until you get more than 1/2 mile away from the antenna, otherwise the airport would be a clogged mess of returns. And you're not worried about a code that is in use but one that is not yet in use. |

It takes at least two sweeps and sometimes as many as 5 sweeps before the radar will tag you up on a code you're squawking. |

I've sometimes been assigned a new squawk code then heard "radar contact" within a couple of seconds (usually, though, it's more like 20-30 seconds, which would agree with what Newps writes).

Dark lonely night and you are the only airplane in the airspace
squawking VFR. You call up for service I'll give you a code and radar contact in the same breath.

"Thomas Borchert" wrote in message ... Ken, leave it on while switching. The AIM says so. This is a really silly argument. Does the AIM say when you can pick your nose or scratch your ass? Guess you better not then! What the heck are you guys getting all worked up about? It's people who rely on a book to do all their thinking that scare me....no ability to use common sense in an emergency, they'll be sitting there thumbing through the AIM or the FARs wondering what to do..... Its too bad there's not a way to test for the ability to differentiate between what is important and what is not. Wow.... -- Thomas Borchert (EDDH) |

"Mike Beede" wrote in message
... The only time it really makes a difference is if you accidentally switch it to the 7500+ neighborhood. A good rule of thumb is to roll in the first number (which at least in the Minneapolis area is never 7) and then do the rest. Do people get 7xxx codes elsewhere in the United States? FWIW, in most of the rest of the world the conspicuity code ("VFR", in effect) is 7000 rather than 1200. There's rather more room for error of the sort you're thinking of. Moreover, when the question is asked on forums in Europe, controllers suggest that *any* random code can cause problems because if you happen upon one that has been assigned to IFR traffic, the radar system picks up the squawk and labels you as that airways flight, which is time-consuming for ATC to fix. Is there no similar issue in the US because of different ATC systems? The issue is less about momentary selection as you pass through the digits and more about cockpit distraction meaning that the wrong code gets left on for a while. Julian Scarfe |
