An emergency can be declared by…
Tower, Pilot, Facility Personnel (Ops, Maintenance)
Duty Priority 1
Separating aircraft and issuing safety alerts as required
Minimum information needed in an emergency…
Aircraft ID, aircraft type, nature of emergency, pilot’s intentions
SID use
Airport system enhancement, expedite traffic flow, reduce pilot & controller work load.
Bird Activity reports
Position, species (if known), course of flight, altitude. Issue alerts for at least 15 minutes or until no longer a factor.
ALNOT
Alert Notice. Generally 50 miles on either side of the route of flight form the last reported position. Cancel when aircraft is located or search is abandoned.
Aircraft orientation options
Radar, Navaids, Pilotage, Sighting by other aircraft
Purpose of the ATC system
The primary purpose of the air traffic control system is to prevent a collision between aircraft operating in the system, to organize and expedite the flow of traffic, and to provide support for national security and homeland defense.
HIWAS
Hazardous Inflight Weather Advisory System. AIRMET, SIGMET, Convective SIGMET. Noted by an H in a circle on FLIPS
Operational Priority
Provide air traffic control services on a “first come first serve” basis as circumstances permit.
Exceptions:
Aircraft in distress, Medevac, SAR, Presidential aircraft, Flight Check aircraft
Recorded with PIREPS
Time, Aircraft position, Type of aircraft, Altitude, When icing is involved: type, intensity, air temp
TAWS
Terrain Awareness Warning System. Provides safety alerts regarding terrain or obstructions. Once recovery maneuver has started, controller is no longer in control. ATC responsibility resumes once maneuver is complete.
Duty Priority 2
Provide support to national security and homeland defense. Report suspicious and/or unusual aircraft.
Duty Priority 3
