Speculation of course.....
I fly for another 744 operator who goes to OAIX regularly and there is no such "tactical departure" in use by us at least......just a standard NADP-1 is adequate, with the possible exception of acceleration height being delayed until 4 or 5000 feet AGL.
of course it is speculation, but its educated, something a forum like this promotes. Of course there is such a thing as a "tactical departure", done it out of many runways in that area on many occasions, pakistan, iraq and lots of other war torn countries employ this manoeuvre! just because your company doesnt do it, doesn't mean "there is no such thing....." Load shift sounds like the most believable "speculation", especially after reading MungoP's post....
