2/19/04Pilot/Controller GlossarySSAA−(See SPECIAL ACTIVITY AIRSPACE.)SAFETY ALERT− A safety alert issued by ATC toaircraft under their control if ATC is aware the aircraftis at an altitude which, in the controller’s judgment,places the aircraft in unsafe proximity to terrain,obstructions, or other aircraft. The controller maydiscontinue the issuance of further alerts if the pilotadvises he/she is taking action to correct the situationor has the other aircraft in sight.a. Terrain/Obstruction Alert− A safety alert issuedby ATC to aircraft under their control if ATC is awarethe aircraft is at an altitude which, in the controller’sjudgment, places the aircraft in unsafe proximity toterrain/obstructions; e.g., “Low Altitude Alert, checkyour altitude immediately.”b. Aircraft Conflict Alert− A safety alert issued byATC to aircraft under their control if ATC is aware ofan aircraft that is not under their control at an altitudewhich, in the controller’s judgment, places bothaircraft in unsafe proximity to each other. With thealert, ATC will offer the pilot an alternate course ofaction when feasible; e.g., “Traffic Alert, advise youturn right heading zero niner zero or climb to eightthousand immediately.”Note: The issuance of a safety alert is contingentupon the capability of the controller to have anawareness of an unsafe condition. The course ofaction provided will be predicated on other trafficunder ATC control. Once the alert is issued, it issolely the pilot’s prerogative to determine whatcourse of action, if any, he/she will take.SAIL BACK− A maneuver during high wind conditions(usually with power off) where float planemovement is controlled by water rudders/openingand closing cabin doors.SAME DIRECTION AIRCRAFT− Aircraft are operatingin the same direction when:a. They are following the same track in the samedirection; orb. Their tracks are parallel and the aircraft areflying in the same direction; orc. Their tracks intersect at an angle of less than 45degrees.SAR−(See SEARCH AND RESCUE.)SAY AGAIN− Used to request a repeat of the lasttransmission. Usually specifies transmission or portionthereof not understood or received; e.g., “Sayagain all after ABRAM VOR.”SAY ALTITUDE− Used by ATC to ascertain anaircraft’s specific altitude/flight level. When theaircraft is climbing or descending, the pilot shouldstate the indicated altitude rounded to the nearest 100feet.SAY HEADING− Used by ATC to request an aircraftheading. The pilot should state the actual heading ofthe aircraft.SCHEDULED TIME OF ARRIVAL (STA)− A STAis the desired time that an aircraft should cross acertain point (landing or metering fix). It takes othertraffic and airspace configuration into account. ASTA time shows the results of the TMA schedulerthat has calculated an arrival time according toparameters such as optimized spacing, aircraft performance,and weather.SDF−(See SIMPLIFIED DIRECTIONAL FACILITY.)SEA LANE− A designated portion of water outlinedby visual surface markers for and intended to be usedby aircraft designed to operate on water.SEARCH AND RESCUE− A service which seeksmissing aircraft and assists those found to be in needof assistance. It is a cooperative effort using thefacilities and services of available Federal, state andlocal agencies. The U.S. Coast Guard is responsiblefor coordination of search and rescue for the MaritimeRegion, and the U.S. Air Force is responsible forsearch and rescue for the Inland Region. Informationpertinent to search and rescue should be passedthrough any air traffic facility or be transmitteddirectly to the Rescue Coordination Center bytelephone.(See FLIGHT SERVICE STATION.)(See RESCUE COORDINATION CENTER.)(Refer to AIM.)SEARCH AND RESCUE FACILITY− A facilityresponsible for maintaining and operating a searchPCG S−1
