Answer 2

When prevailing visibility is below 4sm

7-1-17(c)

Question 3

Light rain

Answer 3

From scattered drops that do not completely wet an exposed surface up to a condition where individual drops are easily seen
7-1-18(a)(1)

Question 4

Moderate Rain

Answer 4

Individual drops are not clearly identifiable
Spray is observable just above the surface
7-1-18(a)(2)

Question 5

Heavy Rain

Answer 5

Falls in sheets
Individual drops are not easily identifiable
Heavy spray to height of several inches
7-1-18(a)(3)

Question 6

Light ice pellets

Answer 6

Scattered pellets that do not completely cover an exposed surface
Visibility is not affected
7-1-18(b)(1)

Question 7

Moderate ice pellets

Answer 7

Slow accumulation on ground
Visibility reduced to less than 7sm
7-1-18(b)(2)

Question 8

Heavy ice pellets

Answer 8

Rapid accumulation on ground
Visibility reduced to less than 3sm
7-1-18(b)(3)

Question 9

Light snow

Answer 9

Visibility greater than 1/2sm

7-1-19(a)

Question 10

Moderate snow

Answer 10

Visibility between 1/2-1/4sm

Question 11

Heavy snow

Answer 11

Visibility less than 1/4sm

Question 12

Trace airframe icing

Answer 12

Ice becomes perceptible
Accumulation is slightly greater than sublimation
7-1-21(b)(1)

Question 13

Light airframe icing

Answer 13

Rate of accumulation may create a problem if flight is prolonged in this environment for over 1 hour
7-1-21(b)(2)

Question 14

Moderate airframe icing

Answer 14

Rate of accumulation is such that even short encounters become potentially hazardous and use of deicing/anti-icing equipment is necessary
7-1-21(b)(3)

Question 15

Severe airframe icing

Answer 15

Accumulation is such that deicing/anti-icing equipment fails to reduce or control the hazard
7-1-21(b)(4)

Question 16

Intercycle ice

Answer 16

Ice that builds up between activation of the deicing system

7-1-22

Question 17

Residual ice

Answer 17

Ice which remains immediately after activation of the deicing system
7-1-22

Question 18

What is the aircraft reaction in light turbulence?

Answer 18

Turbulence that momentarily causes slight, erratic changes in altitude or attitude
Table 7-1-9

Question 19

Light chop

Answer 19

Turbulence that causes slight, rapid and somewhat rhythmic bumpiness without appreciable changes in altitude or attitude
Table 7-1-9

Question 20

Reaction inside aircraft to light turbulence

Answer 20

Occupants feel a slight strain against seat belts.
Unsecured objects may be displaced slightly.
Food service can continue
No difficulty in walking
Table 7-1-9

Question 21

Aircraft reaction to moderate turbulence

Answer 21

Similar to light but of greater intensity
Changes in altitude and attitude occur but aircraft remains in positive control
Causes variations in indicated airspeed
Table 7-1-9

Question 22

Moderate chop

Answer 22

Rapid bumps or jolts without appreciable changes in altitude or attitude
Table 7-1-9

Question 23

Reaction inside aircraft to moderate turbulence

Answer 23

Occupants feel definite strain agains seatbelts
Unsecured objects are dislodged
Food service and walking are difficult
Table 7-1-9

Question 24

Aircraft reaction to severe turbulence

Answer 24

Turbulence that causes large abrupt changes in altitude or attitude
Large variation in indicated airspeed
Aircraft may be momentarily out of control
Table 7-1-9

Question 25

Reaction for passengers in severe turbulence

Answer 25

Occupants are forced violently against seat belts
Unsecured objects are tossed about
Food service and walking are impossible
Table 7-1-9

Question 26

Aircraft reaction in extreme turbulence

Answer 26

Aircraft is violently tossed about and impossible to control
May cause structural damage
Table 7-1-9

Question 27

Occasional turbulence

Answer 27

Less than 1/3 of the time

Table 7-1-9

Question 28

Intermittent turbulence

Answer 28

1/3-2/3 of the time

Table 7-1-9

Question 29

Continuous turbulence

Answer 29

More than 2/3 of the time

Question 30

How far from the center of a wake turbulence vortex should a pilot avoid?

Answer 30

100’ from the core

7-3-2

Question 31

Wake turbulence vortices descend at what rate?

Answer 31

Several hundred feet per minute

7-3-4

Question 32

When close to the ground wake turbulence vortices move how fast over the ground

Answer 32

2 or 3 knots

7-3-4(a)(3)

Question 33

How should a pilot approach a mountain wave?

Answer 33

Approach at 45 degree angle
Add 1,000’ or so of altitude
7-5-6(j)

Question 34

How much wind is required to form a mountain wave?

Answer 34

15kts or more at an intersection angle of not less than 30 degrees
7-5-6(j)(1)

Question 35

When will “Check Density Altitude” be broadcast?

Answer 35

At airports with control tower at or above 2000’msl when the temp reaches a predetermined level
