Would the ARFF index of an airport ever affect a flights legality to be dispatched? By this I mean lets say that its a small regional airport that has Index A ARFF with one truck. For the situation, the truck gets called to respond to assist another fire department in a fire off airport property. Since the only ARFF truck is off property and therefore unavailable, would that nullify its ARFF Index temporarily. Since you would have no notice of the fire and therefore no notice of ARFF assets being unavailable would the flight still be able to be dispatched? Also if the ARFF index of an airport is ever affected long terms like maybe maintenance of the trucks or some other issue, would a NOTAM put out by the airport operator?
