QUESTIONS AND ANSWERS 100% CORRECT



⫸ 1b. Recognize and explain special clouds: Castellanus. Answer: -
Unstable air loft
-Looks like small castle turrets
-Thunderstorms are possible later in the day


⫸ 1b. Recognize and explain special clouds: Billow (K-h=H wave).
Answer: -Unstable air loft
-Look like waves in a cloud
-Indicate wind shear and create CAT (clear air turbulence), related to
Kevin-Helmholtz waves


⫸ 1b. Recognize and explain special clouds: Lenticular. Answer: -
Mountain waves
-Strong winds across mountains
-Look like little disks/UFOs
-Wind oscillations, may indicate mountain wind turbulence


⫸ 1b. Recognize and explain special clouds: Rotor. Answer: -Strong
winds across mountains
-Ragged-looking, form at low altitude under crests of mountain wave
-Indicate BIG HAZARD

,⫸ 1b. Recognize and explain special clouds: Banner. Answer: -
Strong winds across mountains
-Like a banner blowing off the mountain
-Indicate strong turbulence, usually only on an isolated peak


⫸ 1b. Recognize and explain special clouds: Pyrocumulus. Answer: -
Extra heat
-Form over a big fire or volcano
-Heat and moisture so strong it can make a thunderstorm


⫸ 1b. Recognize and explain special clouds: Pileus. Answer: -
Updrafts
-Looks like a little hat over cumulus
-Form over fast-growing cumulus clouds


⫸ 1b. Recognize and explain special clouds: Fractus (scud). Answer:
-Low altitude turbulence
-Ragged and at low altitude
-Turbulent humid air near the ground, indicate high humidity and
strong winds


⫸ 1b. Recognize and explain special clouds: Fumulus. Answer: -
Man-made
-Above smokestacks

,-Water droplets condense over cooling towers


⫸ 1b. Recognize and explain special clouds: Contrails. Answer: -
Man-made
-Trails behind aeroplanes
-From wing-tip vortices on aeroplanes


⫸ 1c. Relate cloud coverage amounts to the visual appearance of the
sky. Answer: -0/8 → Sky clear, nothing (code: SKC)
-1/8, 2/8 → Few clouds, small trails (code: FEW)
-3/8, 4/8 → Scattered, large gaps (code: SCT)
-5/8, 6/8, 7/8 → Broken, small gaps (code: BKN)
-8/8 → Overcast, no gaps (code: OVC)


*Notes:
•Cloud/sky covered measured by eighths of the sky covered, or oktas
•Flying at altitude just above or just below the level of clouds make
them appear to have more coverage than they actually do


⫸ 1d. Define the cloud ceiling, estimate its altitude, and relate it to
cloud coverage amounts. Answer: - Clouds that cover more than half
the sky create a cloud ceiling, constraints VFR pilots to fly below it
and
- When ground visibility is very poor, referred to as vertical visibility
- IFR pilots are still concerned with ceilings, to be able to approach
airport with sufficient time to plan a landing

, -Can estimate cloud ceiling using known landmarks such as
mountains, pole or tree tops


⫸ 1e. Contrast horizontal visibility, vertical visibility, and runway
visual range (RVR), and discuss how they affect aviation.. Answer: -
Three types of visibility and each have their own way of measuring:


1) Horizontal
-Distance you can see horizontally
-Distance between when pilot sees a hazard and when plane hits
hazard is affected by horizontal visibility


2) Vertical
-Distance you can see vertically high or height of the cloud ceiling


3) Runway Visual Range (RVR)
-Measured at airports, how far ahead a pilot can see along a runway
centerline


⫸ 1f. Recognize and interpret weather and obscuration glyphs on
weather charts. Answer:


⫸ 1g. Explain the difference between visual & instrument flight
rules (VFR, IFR) and meteorological conditions (VFC, IFC), and how
they affect aviation. Answer: •Visual Flight Rules (VFR)
