b)In case a holding pattern at a specific point has been instructed and the estimated time of approach has been given in the instructions prior to failure, to conduct the flight so as to arrive by the estimated time of approach after holding at said point;
c)In case, in the instructions prior to failure, a holding at a specific point has been instructed, the estimated time of approach has not been given, and the time at which the next instructions will be issued has been given, to fly toward the airspace over the destination after holding at said point until said time;
