The last couple of things that I need to learn/ understand Flashcards
The definition of nighttime
The time between the end of civil twilight and beginning of morning twilight
Under what condition will true altitude be lower than indicated altitude
At colder than standard temperatures
Pressure altitude
The height above the standard datum point
Absolute Altitude
Height above the surface
True Altitude
The vertical distance of the aircraft above sea level
Ground effect
Result of the interference of the surface of the earth with the airflow patterns about an airplane
Deviation errors of the magnetic compass are caused by?
Certain metals and electrical systems within the aircraft
In the Northern Hemisphere, a magnetic compass will normally indicate initially a turn toward the west if
A right turn is entered from a north heading
Nighttime with respect to the certification of airmen
One hour after sunset and ending one hour before sunrise
Under what condition is pressure altitude and density altitude the same?
At standard temperature
What is the difference between true north and magnetic north
Variation, not to be confused with deviation
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?
A high volume of pilot training or an unusual type of aerial activity
