squawk/transponder?

[jrpilot]

Hello, I was watching my UAL flight from KORD to EGLL and noticed that the pilot was talking about squawk (is squack the same as the transponder)..what exactly is squak, I heard some squawk station is primarly for a teroristic threat or something or is that just some B.S.

your transponder is used to identify your aircraft to ATC on their screens. yes there are certain codes used for emergencies.

so what would it come up with all of the info for ATC

example:

(South West Airlines) SWA Flt. 217?
                              Fl. 330

Squawk 7500 if there are hijackers onboard (i think that's the one)
7700 is the emergency squawk...the VFR squawk will different form country to country (1200= USA, 7000= Sweden etc...)


But it's what Crag said  :)

In the UK at least...

7000 is for general flight (Military at least)

7700 is used for an emergency

7600 is used in event of Comms failure

7500 is used to signify unlawful interference, ie Hijack...

Any other squawks will be assigned by a controller to an aircraft flying IMC under his control...

Where would your squawk change appear at?

You would change it on the transponder in your aircraft and the controller would see the number on their screen...

Actually, the aircraft does not have to be in imc to be issued a squawk code, only in controlled airspace to help with seperation.
