Answer: Broken
,obsc
Which of the following conditions satisfy the conditions of a “ceiling” for aviation?
Answer: Cloud-base height is 15,000 ft AGL and cloud coverage is 5 oktas.
The following weather parameters determine IFR (Instrument Flight Rules) conditions (AGL=above
ground level and SM=statute miles) near airports in North America.
Answer: Cloud ceiling less than 1,000 feet AGL and/or visibility less than 3 SM
One of the requirements for clouds to be considered a ceiling is that:
Answer: clouds cover more than half the sky
Which is the ONE statement about fog that is FALSE?
Answer: Fog is less likely when the air is very humid.
Which is NOT true, regarding how obscurations affect aviation?
Answer: Haze can stick to aircraft causing build-up of too much weight
Suppose you were in an un-pressurized aircraft flying at an altitude of 20,000 feet (about 6,100 m) MSL.
What would you need to do to maintain the ability of your body to function properly at that altitude?
Answer: Need to breathe supplemental oxygen using an oxygen mask.
Which is FALSE regarding the change of aircraft performance when density altitude increases?
Answer: Max service ceiling )highest altitude the aircraft can easily climb to) is increased
As altitude increases, the standard atmospheric pressure __
Answer: Decreases at a decreasing rate (i.e., fast decrease at first, slower decrease at higher altitudes)
Which layer of the atmosphere contains the “good” ozone that absorbs harmful ultraviolet radiation
from the sun?
Answer: Stratosphere
The process of natural turbulence creation by warm air rising in thermals is called
Answer: Free convection
Mountain waves are caused
Answer: When statically stable air flows across mountain ranges
Which type of pilot is most likely to experience CAT (clear-air turbulence) near the tropopause while
flying their aircraft?
Answer: Boeing 747 commercial airliner pilot
,obsc
Thunderstorms are found relative to which type of surface front?
Answer: Along a cold front
What is the typical size of a strong convective thunderstorm?
Answer: 10-15km wide and 10-15km deep
The process of natural turbulence creation by wind shear is called
Answer: Forced convection
Downbursts are (1) and are a hazard to aviation because they can (2)
Answer: (1) rapidly descending downdrafts of air caused by precipitation; (2) push an aircraft towards
the ground
Your airport is in the center of a large flat prairie. Yesterday it rained during the day, causing the air near
the ground to be humid. But tonight there are no clouds and the wind is very light. What type of fog
would you expect later tonight?
Answer: Radiation fog
boundar
Answer:. Mesoscale convective complex
You are the pilot of a helicopter planning a one-hour sight-seeing flight from Vancouver to Whistler, BC
(a ski resort in the mountains north of Vancouver). Which type of weather observation information is
NOT valuable in helping you plan your flight?
Answer: 70 kPa analysis chart
Your airport is on a prairie next to a large lake. It is winter and there is deep snow on the ground. The
lake is not frozen. A light wind is blowing air over the lake toward your airport. It is mid-afternoon, the
ambient air temperature is roughly equal to the lake-surface water temperature, and there are no
clouds in the sky. What type of fog would you expect over the airport?
Answer: Steam fog
If from the ground you see 2/8 coverage of mid-altitude clouds and 3/8 coverage of high-altitude clouds,
then the coverage of only the high-altitude clouds that would officially be reported is
Answer: 5/8 coverage
Which cloud is NOT associated with mountains?
, obsc
Which cloud is not associated with mountains?
Answer: Fumulus
Air with static stability index of S = 10 blowing over a mountain due to a wind speed of M = 30 km/hour.
If the width of the mountain range is 500km, then the Froude number for mountain waves is Fr =
Answer: 0.4
You are a pilot planning a flight from Vancouver BC to Edmonton AB. Your route takes you over
the Rocky Mountains near Revelstoke BC. Using the Froude Number Chart, forecast the type of
mountain waves expected downwind of the Rocky Mountains. The Rocky Mountains are 100km
wide at that point. Your weather charts tell you the static stability index is +1, and the winds are
perpendicular to the Rocky Mountains, from the southwest at 5km/h. Your forecast is for: \
Answer: Violent Mountain Waves
Photo 1d1 was taken from Richmond, BC (a suburb of Vancouver). Notice the North Shore mountains
(elevation roughly 1,500m = 5000ft) in the background and the clouds near those mountains. For this
case, a rough guess at the ceiling is:
Answer: No ceiling
Which is NOT a characteristic of clear-air turbulence (CAT)?
