If a potential conflict with the departing traffic shows up, ATCO is authorized to withdraw the T/O clearance, order the A/C to hold position or abort T/O as needed. Would you agree?
Specifically if a known or recognized risk of collision between the departing traffic and ground installations and mobile obstacles in the “beyond runway end” area, but still within aerodrome’s controlled area exists.
ATC “controls” every operation within the airport perimeter (fence), otherwise we wouldnt be calling them Controllers if they were not, would we?
ATCO’s operational responsibility for providing safety in this sense extends well beyond the maneuvering area.
You have now moved on from your original post to add specific issues to it.
As I have indicated in an earlier post, risk management of the RESA is the responsibility of the aerodrome operator, not ATC. Speaking from personal experience as having been a licensed ATCO for 42 years, ATC training does not include management of RESAs or other runway safeguarding measures. If they need to become involved with this it is something that would be managed on a case by case basis at individual aerodromes at the request of the aerodrome operator.
If there is a need for a person and/or vehicle to enter a RESA any risk to safety must be managed by the aerodrome operator. In this scenario if entry into a RESA is required the aerodrome operator is the responsible authority to put in place procedures to mitigate the risk. It is therefore probable that ATC would be requested to manage the risk on behalf of the aerodrome operator, thereby extending their
normal area of responsibility. This could then result in a requirement for ATC to issue approvals for RESA entry.
