As MacBoero says, we are mandated a landing runway on westerlies (27s), and that switches at 1500 local (due noise)
On easterlies (09s), we are mandated a departure runway (09R - again due noise) so because we are usually busy, we tend to land only on 09L. However, if it's quiet outbound, or the inbound delay builds up unacceptably, we do land the odd one on 09R...this tends to be T4 traffic to save them and us a long taxy and runway crossing.
