The alert for the different types of detection is always different... I am guessing your GSD is training for Air Scent and not tracking.

As far as I know though for FEMA which has the most stringent certification standards the dog must stay with the victim/target and have an audible aka bark alert as the indicator.

There are MANY different standards out there though that I have found and read. It all honestly depends on what is required in your region or with the K9 SAR group you are with.

I use the bark at where the victim is, as do all the teams I've trained with. Since our dogs do wilderness and urban search we don't want them going back and forth on the rubble.

Yeah that was my understanding and the main reason why it is a FEMA standard for K9 SAR.
