As per the above quoted CAR: 'in an EMERGENCY'-thus requiring a state of emergency to be declared. As someone who has done more autolands than the average QF pilot would do in their entire career, in many different parts of the world, there is no way I would do one at an airport not certified unless I declared a MAYDAY state. Note: I am not saying it couldn't happen to me, but that this is the ATC handling priority I would want.
