It is utterly ridiculous that CASA wants to certify things that come as factory standard. Either the type is approved or it isn't. We cannot have the situation where CASA lets you register a particular aircraft then bans you from using any of it's factory standard equipment. Maybe it's time to lean on the manufacturers to lean on the government.
It would be like buying a brand new Mercedes and Vic Roads telling you can't turn on the cruise control and the air con!
