if there is a pilot report of icing in an area you are flying through, you are flying into an area of
----- - Answer known icing.
On days when there is -------- in the air, ice can form on aircraft leading edge surfaces at
altitudes where -------temperatures start - Answer visible moisture, freezing
----- are Water drops with a diameter greater than 50 micrometers that exist in a liquid form at
air temperatures below 0 °C - Answer Supercooled Large Drops SLD
SLD are Water drops with a diameter greater than 50 micrometers that exist in a liquid form at
air temperatures below----- - Answer 0 °C
ice typically forms on an aircraft in flight when the aircraft's cold surface collides with water
droplets that have remained ----although they are below the freezing point (supercooled water)
- Answer liquid
at temperatures between -------there is a significant icing threat due to the amount of
supercooled liquid present within the clouds - Answer 0ºC and -15ºC
---- ice forms when the remaining liquid portion of the water drop flows out over the aircraft
surface, gradually freezing as a smooth sheet of solid ice - Answer clear
formation of ------ ice occurs when droplets are large, such as in rain or in cumuli-form clouds. -
Answer clear
----- ice is hard, heavy, and tenacious. Its removal by deicing equipment is especially difficult -
Answer Clear
---- ice forms when water drops are small, such as those in stratified clouds or light drizzle. -
Answer rime
the liquid portion remaining after initial impact freezes rapidly before the drop has time to
spread over the aircraft surface is an example of ---- ice - Answer rime
, The small frozen droplets trap air giving the ice a white appearance. ---- ice is lighter in weight
than clear ice and its weight is of little significance - Answer rime
------ icing can form rapidly when water drops vary in size or when liquid drops intermingle with
snow or ice particles. - Answer mixed clear and rime
----- is formed when ice particles become embedded in clear ice, building a very rough
accumulation sometimes in a mushroom shape on leading edges. - Answer mixed
ice may be expected to form whenever there is ------ in the air and temperature is near or below
freezing - Answer visible moisture
an exception is ----- which can occur during warm weather with no visible moisture present -
Answer carburetor icing
carburetor ice occurs due to the effect of fuel ------and the decrease in ----- in the venturi, which
causes a sharp temperature drop in the carburetor. - Answer vaporization , air pressure
---- ice may cause the engine run rough or quit working - Answer carburetor
----- heat may be applied to prevent carb ice. - Answer carb
carburetor ice is most likely to occur when temperatures are below ------and the relative
humidity is above ---- percent. - Answer 70°F (21°C) , 80%
carb icing can occur even with temperatures as high as ----- and humidity as low as----percent. -
Answer 100°F (38°C), 50 %
Frost is an effective aerodynamic spoiler and will increase ------. - Answer drag
----- ice will change the aerodynamic shape of a surface and destroy lift. - Answer Rime
---- Ice will add significant weight in addition to changing the aerodynamic shape of a surface
and destroying lift. - Answer clear
ice ----- systems allow the anti-ice and de-ice systems to operate only when needed. - Answer
detection
