ERSA?

Andy

the acronym is so intuitive that I'm sure you wont need me to
elaborate.

sarcasm off

ersa is the 'enroute supplement australia' it is a large book of the
details of commercially used airfields in australia.

it is pretty useless for private flying beause of the subset of
airfields featured.

your windsocks must be made from concrete because we actually use ours
to determine the pattern. (hint: land into wind)
