Out of curiosity, what stands are these and where does the BA B763 usually park?
According to
www.EGPHForum.com;
Main apron stands that can accommodate a B763 (without winglets) are 2, 4 and 10. Stand 9 is B752 sized (without winglets
AFAIK).
SE apron stands that can take wide-bodies are as follows but are subject to significant ACN/PCN restriction because of the relatively weak taxiways that link it to taxiway Alpha. (NB. PCN for taxiway Mike was 31F/C/X/T in BAA days and increased to 37/F/A/W/T the week that GIP took over. The increase from 31 to 37 is helpful but the change of sub-grade from C to A is more significant);
17 A/c up to B744 Only when stands 16/18/19 Not in Use
18 A/c up to B764 Only when stands 17/19 not in Use
