AVIA 110 - Lab Exercise# 10
1) How does ca
uretor ice form, how is the pilot made aware of it (fixed pitch prop, and
how is it removed. How is the ca
uretor heat system tested?
2) With regard to ca
uretor ice, what advantage does a fuel injection system have?
3) What are five dangers of structural ice?
4) With regards to ground icing (dew-frozen, frost, or snow), which needs to be completely
emoved before flight?
5) Describe rime ice with regards to:
a. Appearance
. Temperature of formation
c. Speed of building
d. Effect on airfoil aerodynamics, aircraft weight, or both
e. Ease of removal in flight
f. Recommendation for flight changes if encountered
6) Describe clear ice with regards to:
a. Appearance
. Temperature of formation
c. Speed of building
d. Effect on airfoil aerodynamics, aircraft weight, or both
e. Ease of removal in flight
f. Recommendation for flight changes if encountered
7) List two ways that large Liquid Water Content (LWC) and Supercooled Large Droplets
(SLD) produce the most dangerous icing conditions.
8) What is meant by runback icing and what is its danger?
9) How is freezing rain produced and how should the flight be altered if it is encountered?
10) How are the following PIREP's interpreted:
a. . ......... / IC SVR RIME XXXXXXXXXXDURD
. . ......... ./ IC MOD MIXED 090 IN CLOUDS
c. . .......... / IC LGT RIME XXXXXXXXXXDURD ON FINAL RWY 6
11) What are three ADDS weather products that would help you understand the icing
hazard on a certain flight?
12) List three "types" of visibility observations obtained on the ground.
13)Give the basic definition of the term "ceiling" and the limitations of AWOS and ASOS
automated stations in their reporting of this value.
14)Give the fixed standard definition of VFR, MVFR, IFR and LIFR
1 S)Who is the final authority as to the ceiling and visibility for a given flight?
16)With regards to lowering ceilings and visibilities, what is the biggest cause of serious
weather related accidents for VFR pilots? What type of weather system (warm, cold,
occluded, stationary) is primarily responsible for generating these dangerous
conditions?
17)What is the visibility difference between Fog (FG) and Mist (BR)?
18)With the Temp/Dew Point spread as follows and a cooling trend is in place, how soon
may fog be expected to occur:
a. 2 Deg: F:
. 5 Deg. F:
c. 12 Deg. F:
19)What is the shorthand aviation designation for these visibility limiters:
a. Ice Fog:
. Shallow Fog:
C. Drizzle:
d. Light Rain:
e. Blowing Snow:
f. Smoke:
g. Haze:
h. Dust:
i. Blowing Dust:
20)List three weather products (ADDS and/or LEIDOS) that depict CURRENT VMC/IMC
weather conditions
21) List three weather products (ADDS and/or LEI DOS) that depict FORECAST VMC/IMC
weather conditions
