RUNWAY VISIBILITY VALUE - (See Visibility)
RUNWAY VISUAL RANGE/RVR (P/CG) - (See Visibility)
RUNWAY VISUAL RANGE/RVR (ICAO) - (See Visibility)
RUNWAY VISUAL RANGE (JCS, NATO) - The maximum distance in the direction of take-off or landing at which the runway, or specified lights or markers delineating it, can be seen from a position above a specified point on its centerline at a height corresponding to the average eye level of pilots at touchdown.
RVSM Airspace (FAA AC 91-RVSM) - Any airspace or route between FL290 and FL410 inclusive where aircraft are separated vertically by 1000 ft (300 m).
SAFETY ALERT - A safety alert issued by Air Traffic Control to aircraft under their control if Air Traffic Control is aware the aircraft is at an altitude which, in the controller's judgment, places the aircraft in unsafe proximity to terrain, obstructions or other aircraft. The controller may discontinue the issuance of further alerts if the pilot advises he is taking action to correct the situation or has the other aircraft in sight.
(1)
TERRAIN/OBSTRUCTION ALERT - A safety alert issued by Air Traffic Control to aircraft under their control if Air Traffic Control is aware the aircraft is at an altitude which, in the controller's judgment, places the aircraft in unsafe proximity to terrain/obstructions; e.g., “Low altitude alert, check your altitude immediately”.

(2)
AIRCRAFT CONFLICT ALERT - A safety alert issued by Air Traffic Control to aircraft under their control if Air Traffic Control is aware of an aircraft that is not under their control at an altitude which, in the controller's judgment, places both aircraft in unsafe proximity to each other. With the alert, Air Traffic Control will offer the pilot an alternate course of action when feasible, e.g., “Traffic alert, advise you turn right heading zero nine zero or climb to eight thousand immediately”.

The issuance of a safety alert is contingent upon the capability of the controller to have an awareness of an unsafe condition. The course of action provided will be predicated on other traffic under Air Traffic Control's control. Once the advisory is issued, it is solely the pilot's prerogative to determine what course of action, if any, he will take.
SAIL BACK - A maneuver during high wind conditions (usually with power off) where float plane movement is controlled by water rudders/opening and closing cabin doors.
SAME DIRECTION AIRCRAFT (P/CG) - Aircraft are operating in the same direction when:
a.
They are following the same track in the same direction; or

b.
Their tracks are parallel and the aircraft are flying in the same direction; or

c. Their tracks intersect at an angle of less than 45 degrees.
d. SAY AGAIN - Used to request a repeat of the last transmission. Usually specifies transmission or portion thereof not understood or received, e.g., "Say again all after ABRAM VOR."
