Duke - the same rule already applies in EASALAND for CAT flights after a similar spate of crashes and a large body count.
It my seem over the top to you but ask yourself? Would you allow your kids to be flown, at night, over the inky blackness in an unstabilsed machine.
It never ceases to amaze me how dumb we pilots seem when we show determination to continue to repeat the same mistakes in the same circumstances, resisting all efforts to make progress!!
About time CASA!!
