Non controlled airfield circuit entry
Can someone please assist? I have been trying to find out an authoritative source for circuit entry procedures to CTAF and CTAF(R) airfields. I have discovered CAR166 which authorises straight in approaches, joining on cross wind, down wind and on base, but cannot find any reference to midfield cross wind joins or joining the circuit at 45 degrees to the downwind leg which if memory serves me correctly were introduced a few years ago and which were publicized by a free DVD. Am I being a little cynical here or are we being encouraged (directed) by CASA to use procedures which are not in fact covered by regulation? If that is the case are we being set up for a huge lawsuit should we be involved in an accident joining the circuit midfield crosswind or at 45 degrees to downwind?
