Since this thread's been bumped - what are the legal requirements regarding holding a current AVID? Going to get mine renewed soon as it's close to expiring - but unsure what it's actually for. Of course, we need to carry our licence and current medical when we fly, and wear an ASIC when in security controlled areas - does holding a current AVID form part of the legal requirement to carry your licence in flight? As the licence itself doesn't actually expire. Or is it another excuse for CASA to charge $170 for a few minutes' work?
