Checker
I was just wondering what Checker does during a runway inspection, and finds something major. I understand small objects etc. may be retrieved straight away, but what about something more, possibly runway damage or similar? Does he have authority to immediately have the runway closed, or is the decision made elsewhere?
And are landing aircraft advised of possible damage etc?
And finally, what does vehicle, callsign Seagull, do?
Many thanx and sorry in advance for being so ignorant.
