Genuine Question:
Are these "spotters",
ATCOs?
Do they hold a current validation?
What positions/sectors are they valid on?
Do they have direct access to the r/t?
Is it a CAA licensed position?
What are their responsibilities?
If the incident as previously mentioned occured went one step further, who is responsible for the outcome - the "spotter" or the validated ATCO working the position?
Interesting.
