you are the ARFF Commander at the Phoenix Sky Harbor
International Airport. Air Traffic Control
(ATC) Ground control picks up the crash line and tells you that
there is an In-Flight Emergency (IFE) inbound to PHX. They are 20
minutes out and have 157 souls on board (SOB). The plane
is a Southwest 737-400 that has reported smoke in the cabin. They
are en route to Runway 7L.
1. Discuss where you would stage your ARFF crew for the Rapid
Response Area (RRA), i.e., what is the route from the firehouse and
what taxiway would you stage at?
2. What obstacles would you be thinking of if the Critical
Rescue and Fire Fighting Access Area (CRFFAA) was needed?
