Speedbird 23F Heavy - On JFK Delivery, 11.30pm GMT

Wed Nov 29, 2006 8:47 am

Hi,

I'm listening to JFK delivery right now, (28th Nov, 11.30pm UK time) via this website:

http://audio.liveatc.net:8012/kjfk_del_gnd

I've heard "Speedbird two-three foxtrot heavy" several times, I just wondered if anyone knows what this call-sign refers to?

As far as I can make out, BA doesn't fly freighter service to JFK (normally signified by the 'F' in the flight number). BA23F does show-up on this site - http://www.panynj.gov/aviation/fidsframe_jfk.html as a scheduled 1830hrs departure from JFK to LHR. However, the passenger flight with a 1830hrs departure time is BA112!

I'm very confused..........  Confused

Maybe it's a flight operated by Global Supply Systems for British Airways World Cargo? Does Global Supply Systems even use the BA callsign?

See

http://flightaware.com/live/flight/BAW23F

This is a 747-400, so I would suggest it is a passenger flight. See this recent thread also:

Good information, thank you. So as far as I can make out, it's BA112, the regularly scheduled 1830hrs departure, that operates as "Speedbird two-three-foxtrot Heavy" instead of Speedbird one-one-two heavy".

There is Aer Lingus 112, Aerosvit 132, American 122, Delta 112 and Air India 112 that all depart around the same time, so the use of 23F makes sense to avoid confusion, in this instance.

Got it, thanks!

Airlines often use codes like those, usually to avoid ATC confusion. Some other BA examples are:

BA058 CPT-LHR = BA58L
BA092 YYZ-LHR = BA5CA
BA098 YYZ-LHR = BA7TA
BA176 JFK-LHR = BA14J
BA212 BOS-LHR = BA45B
BA214 BOS-LHR = BA14G
BA215 LHR-BOS = BA51G
BA216 IAD-LHR = BA6W
BA218 DEN-LHR = BA17V
BA288 PHX-LHR = BA28F
BA292 IAD-LHR = BA27W
BA296 ORD-LHR = BA24R

Yes, they're increasing all the time and becoming rather common nowadays. Alitalia has a few alpha-numerics across the Pond as well, namely AZA63M, AZA63R and another one which is really bizarre - it's something like AZA7P9!

Yes they do.

Always in fact. Usually Speedbird 357_ sequence on the Pond iirc.

As noted above, BA are using alpha numeric call signs instead of the usual flight numbes to avoid ATC confusion. Hopefully someone will post the cross-references in due course!

Our AZ625 SFO-MXP was often ATC coded as AZA62F. Reason given was less ATC confusion...as stated often above. This is not an uncommon event; a lot of UA flights had a special 8000 series ATC code (for which reason I don't know why...just heard it on ch 9). Haven't flown UA for awhile now so don't know if they still do this.
