I recently completed a VFR flight from YBTH to YSNW (or YSHL, cannot remember). At no stage did I reveived a call stating what the arrival runway was so I decided to land on rwy 26. However when I announced downwind (without knowing what runway) it promptly said roger, downwind runway 36 (or words to that effect. I beleive the arrival is an untowered airport.
Don't know if I did anything wrong, so my question is how do I determine what runway PF3 is going to assign me before calling downwind?
Many thanks
