After the last update, widebody a/c can no longer spawn at LROP and LRSB.
LRSB has stands capable of handling C17s and 747Fs but I’m not familiar to which stands are allocated normally.
For LROP it’s the following:
Gates 107, 107A, 109, 109A can handle a/c categ such as 747s.
Gates 108 and 110 can take max 777-200, not 300 unfortumately due to wingspan and length.
Stands 201-205 and 201A can take a/c as big as a 747.
