Transponder code switching

AIM or no AIM, I'd put it to standby while changing the squawk. 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.

I suspect it doesn't make much difference as it's over in a moment.

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?

Would be kind of cute to "accidentally" select 44xx and
see what altitude they assign...

I doubt that they would confuse someone flying at FL065 with someone at
FL650.

The saying you won't hear: "Cessna Skyhawk, climb to FL650, Squawk 4444..."

Here are some Canadian default codes (uncontrolled, or no transponder
code yet assigned):

1400 VFR above 12,500 ft
1000 IFR in low-level airspace
2000 IFR in high-level airspace


All the best,


David

And there are other codes that cause alarms that are secret, so don't
worry about it and just switch the numbers.

Newps, quick, hide in the FAR's!!!


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!
