ATSC 113 Flying Module Exam
Questions with Correct Answers
what happens when you have Poor Vertical Visibility? - Answer-Limits runway
acquisition
what is Runway Visual Range (RVR)? - Answer-- Indicates how far ahead a pilot can
see along a runway centerline
- Only reported when visibilities are poor
what do weather glyphs and codes look like? - Answer-LOOK AT DIAGRAM
what are some basic weather symbols and codes? - Answer-LOOK AT DIAGRAM
what are some weather code modifiers? - Answer-LOOK AT DIAGRAM
what are some weather descriptors and obscurations? - Answer-LOOK AT DIAGRAM
what are Visual Flight Rules (VFR)? - Answer-- You fly by mostly looking out the
window; therefore, you require good visibility and need to stay out of clouds
What is Visual Flight Conditions (VFC)? - Answer-Horizontal Visibility:
- Must be 3 statue miles or more (preferably 5 statue miles or more)
Ceiling:
- Must be 1000 ft. above the airport (preferably 3000 ft. above the airport)
what is Marginal VFR (MVFR)? - Answer-Conditions where VFR is allowed but visibility
is poor
Horizontal Visibility:
Between 3-5 statue miles
Ceiling:
Between 1000 ft. - 3000 ft. above the airport
what are Instrument Flight Rules (IFR)? - Answer-You conduct most of the flight by not
looking out the window; therefore, you use tools and displays
What is Instrumental Flight Conditions (IFC)? - Answer-Horizontal Visibility:
Less than 3 statue miles
Ceiling:
Less than 1000 ft. above the airport
, Bad weather is called Instrument Meteorological Conditions (IMC) which is weather that
VFR flight is not allowed
When does fog form? - Answer-LOCATION:
- Many fogs form in low spots or in valleys
HUMIDITY:
- Forms when there is high humidity
TEMPERATURE:
- When unsaturated air is cooled to its dew-point temperature (temperature at which
water vapour starts to condense into liquid droplets)
WINDS:
- Forms when winds are relatively slow or near calm CLOUD-COVER: - Forms when
there is less cloud cover, so ground can be cooled and cool the air above it
How does fog affect aviation? - Answer-- Fog is an obscuration that reduces horizontal
visibility
- Prevents pilots from seeing where they are going
- Prevents weather observers from seeing the sky condition and weather above the fog
What are different types of fog? - Answer-a. RADIATION
- Cool ground cools the air that touches the ground and as night progresses, fog gets
deeper
b. ADVECTION
- Humid air blows over a colder surface, causing the air temperature to decrease to
dew-point temperature
c. UPSLOPE
- Air is pushed upward when wind blows air against a hill slope and if it gets sufficiently
cold, then fog can form
d. PRECIPITATION/FRONTAL
- Formed by adding moisture via evaporation
e. STEAM
- Occurs when cold air moves over warm humid surfaces like unfrozen lakes or oceans
during early winter
what are the types of obscurations? - Answer-1. SMOKE
- Comes from factories, cars, and forest fires
- Reduces visibility and makes it hard to breathe
2. VOLCANIC ASH
- Very abrasive, like sandpaper
- Can cause bearings and gears to wear-out very quickly and to fail or seize Clogs and
contaminates various filters and ventilation systems
- Reduces visibility and adds weight to aircraft
3. BLOWING SAND AND DUST
- Haboobs: sand storms, created by outflow winds from thunderstorms
