At SQ, for the most part, the nose and side door are used at the same time.
"same time" meaning offloading using the side door first for any Q7's you have on board, then move to the nose door for the Q6's?
If it's all Q6's I prefer to go straight out the nose. Much quicker, 1 man job.
If it's a mix then I plan the Q7's closest to the side door and, if ground handling permits, off those first then go to the nose for the remainder.
If there's only 1 hiloader then the time taken to move it from the side to the nose negates the gains made by offloading some out the nose.
VIT was always good, full maindeck of Q6's inbound, only ever enough staff for the ground equipment so nose offload on your own was ideal.
