When flying long distances, a world aeronautical chart (WAC) for the determination of height, position,alternative landing areas,airspace boundaries and radio frequencies.
<u>Explanation:</u>
For those aircraft flying at higher distances, WAC is used for the purpose of navigation. This chart is very helpful in finding current position, alternate routes, safe heights for flying,etc. It also helps in choosing the best alternate route for reaching the desired location. It provides the person flying at higher distances with that of radio frequencies and airspace boundary.
Strategic planning can be done for flights with this chart. Using this chart we can view the whole area of flying. There is a revision of these charts every year but for the areas like Mexico and Caribbean since the revision takes place once in 2 years.
Answer: True
Explanation:
The ratio of the map distance to ground distance usually involves the use of inverse relationship between the extent of coverage of the entire map and the amount of detail visible. And this relationship is always written as 1/x or 1:x.
Where the numerator represents the map distance which always equals 1 and the denominator represents the ground distance which has similar units as the numerator.
