Which is true concerning the blue and magenta colors used to depict airports on Sectional Aeronautical Charts?
- Airports with control towers underlying Class B, C, D, and E airspace are shown in blue.
- Airports with control towers underlying Class A, B, and C airspace are shown in blue; Class D and E airspace are magenta.
- Airports with control towers underlying Class C, D, and E airspace are shown in magenta.
- Airports with control towers underlying Class B, C, D, and E airspace are shown in blue.
When a control tower located on an airport within Class D airspace ceases operation for the day, what happens to the airspace designation?
The correct answer is B. During the hours the tower is not in operation, the Class E surface area rules or a combination of Class E rules and Class G rules will become applicable. The Airport/Facility Directory will contain the specifics for each airport. (AIM Chapter 3-2-5)
absence of the sky condition and visibility on report means
The absence of a sky condition or ceiling and/or visibility on ATIS indicates a sky condition or ceiling of 5,000 feet or above and visibility of 5 miles or more. A remark may be made on the broadcast, “the weather is better than 5000 and 5,” or the existing weather may be broadcast.
Pre-Ignition happens when
hot spots in the combustion chamber ignite the fuel/air mixture in advance of the normal ignition.
large accumulations of carbon monoxide in the body results in
Carbon monoxide reduces the ability of the blood to carry oxygen. Large accumulations result in loss of muscular power. Carbon monoxide poisoning results in an oxygen deficiency.
clouds are divided into four families according to their
Clouds are divided into four families according to their height range: low, middle, high, and clouds with extensive vertical development.
- When the term “light and variable” is used in reference to a winds aloft forecast, the coded group and wind speed is
A. 9999 and less than 10 knots.
B. 9900 and less than five knots.
C. 0000 and less than seven knots.
The correct answer is B. A winds aloft forecast of 2722, for example, would indicate 22 knots of wind from 270 degrees. 9900 means no specific direction (variable) and less than 5 knots (light). (Pilot’s Handbook of Aeronautical Knowledge, page 12-14)
The minimum weather condition for special VFR in class B, C, D, or E is
1 Mile flight visibility and clear of clouds
What are the Dangers of a MOA?
Military training activities that necessitate acrobatic or abrupt flight maneuvers
what are the hazards in an alert area?

What are the hazards of a restricted area?
Unusual, often invisible hazards, to aircraft such as artillery firing, aerial gunnery, or guided missiles
What values are used for winds aloft forecast?
A) Magnetic direction and knots
B) Magnetic direction and miles per hour
C) True direction and knots
True direction and knots
the uncontrolled firing of the fuel/ air charge in advance of normal spark ignition is called
Pre-ignition
A precaution for the operation of an engine equipped with a constant-speed propellor is to
avoid high manifold pressure settings with low RPM
What are the characteristics of moist unstable air
Cumuliform clouds and showery precipitation
One alcoholic drink (one ounce of liquor, one bottle of beer, or four ounces of wine) can be detected in the breath and blood for at least
3 hours
Graphical forecasts for aviation (GFA) are weather charts best used to
Learn the forecast weather along your proposed route of flight as well as at your destination if it has no terminal forecast
During which phase of flight is a pilot at increased odds of experiencing somatogravic illusions
takeoff
The mature stage of a thunderstorm begins with
The start of precipitation
A pilot can expect a wind shear zone in a temperature inversion whenever the windspeed at 2,000 to 4,000 feet above the surface is at least
25 knots
The presence of ice pellets at the surface is evidence that there
Is a temperature inversion with freezing rain at a higher altitude
With respect to the certification of airmen, which is a class of aircraft?
a) Airplane, rotorcraft, glider, lighter-than-air
b) Single-engine land and sea, multiengine land and sea
c) Lighter-than-air, airship, hot air balloon, gas balloon
Single-engine land and sea, multiengine land and sea

A) Normal, Utility, acrobatic
B) Airplane, rotorcraft, glider
c)Landplane, seaplane
Normal, Utility, acrobatic
What is the advantage of a constant-speed propellor?
A) Permits the pilot to select and maintain a desired cruising speed
B) Permits the pilot to select the blade angle for the most efficient performance
C) Provides a smoother operation with stable RPM and eliminates vibrations
Permits the pilot to select the blade angle for the most efficient performance
Detonation occurs in a reciprocating aircraft engine when
The unburned charge in the cylinder explodes burns instead of burning normally
The angular difference between north and magnetic north is
Magnetic Variation
The relationship of lift, drag, thrust, wight when the plane is in straight and level flight
Lift equals weight and thrust equals drag
Loading the airplane to the most Aft of CG will cause the airplane to be
Less stable at all speeds
Upon severe turbulence what flight condition will pilots attempt to maintain
-Constant altitude and airspeed
-Constant angle of attack

If the temp/dewpoint spread is small a decreasing, and the temp is 62 degrees F what type of weather is most likely to develop?
Low clouds or fog
Before passengers can be carried in an aircraft that has been altered in a manner that may have appreciably changed its flight characteristics, it must be flight tested by an appropriately- rated pilot who holds at least a

What is the definition of load factor
Additional weight carried by the wings divided by the weight of the aircraft
which would most likely cause the cylinder head temperature and engine oil temperatures to exceed the normal operating range

-Using fuel that has a lower than specified fuel rating
-operating with higher than normal oil pressure
