Human Factors; Procedure
Departing runway 19 LADIX 8D; after making initial turn to 098 and leveling at 900 meters by ATC (LNAV/VNAV engaged 250 knots in the speed window); I turned on the center autopilot. We were given a climb clearance to I believe 5;400 meters. [I] advised ATC unable altitude restriction at [intersection] AA282; they advised no problem. Then at [intersection] AA283 in LNAV 250 knots in the speed window we made a climbing right turn to 186; at which time ATC gave us an immediate turn to 210 and asked why we made a wide turn at AA283. I believe he suggested possible encroachment on military airspace. The turn was made on complete auto-flight at 250 knots; which after thinking back I did see the turn arc was wide; just how far I don't know. I advised ATC that we made a standard turn at AA283 and that seemed to satisfy them. As with some other departure procedures such as the LADIX 8E; they should not be allowed on the 747; due to the [occasional] total lack of communications. We have brand new First Officers in the right seat and very behind. I fly out of ZBAA sometimes 2 times a month and I know not to accept the LADIX 8E but in this case I accepted the LADIX 8D not foreseeing the problem with the turn radius at AA283. Every time I think I have seen it all; something new comes along. I always turn on the autopilot soon after takeoff so I can monitor better. I can't emphasize enough with brand new people to the 747 and China this can be challenging at best; the only time I seem to write a [report] is departing ZBAA; and I should have written more.
B747 Captain reported ATC advised them of a track deviation departing ZBAA.
