Weeping wing
Deicing systems pump fluid from a reservoir through a mesh screen embedded in the leading edges of the wings and tail. depend on airflow as well, and if the primary air intake ices, an alternate air door either opens automatically
Taxi to—hold short
A clearance to begin taxiing, but enroute to the taxi clearance limit you must hold short of another taxiway or a crossing runway as specified by the controller.
Flashing green
Cleared for taxi or Return for landing (to be followed by steady green at the proper time)
Wake Turbulence
Wake turbulence is a concern whenever small aircraft share an airport with larger ones. The powerful vortices that spiral off the wing tips of heavier aircraft—turboprops and business jets, as well as airliners— can suddenly and unexpectedly toss a small airplane out of control.
TRSA
Terminal Radar Service Areas areas where participating pilots can receive additional radar services. The purpose of the service is to provide separation between all IFR operations and participating VFR aircraft.
Atmospheric Conditions
Haze, flight over open water, or an obscured horizon can make it difficult to see distant objects, impairing the ability to refocus vision.
Wing Stall
The wing will ordinarily stall at a lower angle of attack, and thus a higher airspeed, when contaminated with ice. Even small amounts of ice will have an effect, and if the ice is rough, it can be a large effect.
Night Landing Illusions
Landing illusions occur in many forms. Above featureless terrain at night, there is a natural tendency to fly a lower-than-normal approach. Elements that cause any type of visual obscuration, such as rain, haze, or a dark runway environment also can cause low approaches.
PAPIs
Precision approach path indicators light units similar to the VASI but are installed in a single row of either two or four light units.
Carburetor icing
affects engines with carburetors, and air intake blockage, which affects both carbureted and fuelinjected engines.
