Down wind checks ? not a good idea!
I think it is time for these checks to be re-named, with all the avoidance of "noise sensative areas" that flying seems to involve now I think it is unwise to tie a checklist to geographical part of the flight that might not happen.
It would seem to me that "pre landing check" would be a more realistic name for these checks as there is a danger that if a downwind leg is not flown the downwind checks won't get done.
