Teacherjh,
AIM or no AIM, I'd put it to standby while changing the squawk. Yeah, right. And while we're at it, why not ignore runway markings, visibility requirements and whatever else is in the AIM, too? Jeeze! -- Thomas Borchert (EDDH) |

Then turn it to mode C I had an instructor tell me to just change it to the new code without turning it to stand by first. Like to hear from controllers as to what they prefer. Just change the numbers, it doesn't matter how you do it. On my plane the transponder never goes into standby, there's no good reason to ever turn your transponder off of the ALT position if it is working properly and you have an avionics master. |

You're not supposed to squawk an incorrect code either, and if you're not on standby, that's what you're doing while changing. And just how glacially do you change codes? Center radar antennas rotate at 12 seconds per sweep, terminal radars at 6 seconds per sweep. When you are changeing codes the target on the scope coasts for several sweeps until your new code stays the same for about three sweeps. I suspect it doesn't make much difference as it's over in a moment. Exactly. |

And there are other codes that cause alarms that are secret, so don't
worry about it and just switch the numbers. Sven wrote: "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? Not sure about assigning 7xxx codes... I found a list of transponder codes besides the 1200/7500/7600/7700: 1255 is for VFR aircraft engaged in fighting forest fires 1277 is for VFR aircraft engaged in search & rescue operations 4000 is reserved for VFR military aircraft on training missions 4400-4477 are reserved for aircraft operating above FL600 At no time should 7777 be used, as this is for military interception procedures (Source: 2003-2004 Iowa Airport Directory page 135) Are there others? |

"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". |

Just saw this play (again) this past week. One of my favorites. From A Man for All Seasons, by Robert Bolt Setting - Sir Thomas More has declined to employ Richard Rich, who has just left the room. Wife: Arrest him! Mo For what? Wife: He's dangerous! Roper: For all we know he's a spy! Daughter: Father, that man's bad! Mo There's no law against that! Roper: There is, God's law! Mo Then let God arrest him! Wife: While you talk he's gone! Mo And go he should, if he were the Devil himself, until he broke the law! Roper: So, now you give the Devil the benefit of law! Mo Yes! What would you do? Cut a great road through the law to get after the Devil? Roper: Yes, I'd cut down every law in England to do that! Mo Oh? And when the last law was down, and the Devil turned 'round on you, where would you hide, Roper, the laws all being flat? This country is planted thick with laws, from coast to coast, Man's laws, not God's! And if you cut them down (and you're just the man to do it!), do you really think you could stand upright in the winds that would blow then? Yes, I'd give the Devil benefit of law, for my own safety's sake! -- Montblack |
