Land Features: contour lines

Question 1

Contour lines join points equal (elevation, landing).

Answer 1

elevation

Question 2

On sectionals, basic contour lines are spaced at (500’, 200’) intercals

Answer 2

Intermediate contours are typically at (250’, 300’) intervals in moderately level or gently rolling areas.

Question 3

Auxiliary contours at (25’, 50’), (100’, 130’), (125’, 135’), or (150’, 175’) intervals occasionally show smaller relief features in areas of relatively low relief.

Answer 3

50, 100, 125, 150

Question 4

The (number, pattern) of these contour lines and their spacing gives the pilot a visual concept of the (air, terrain).

Answer 4

pattern; terrain

Question 5

Widely spaced contours represent (gentle, steep) slops, while closely spaced contours represent (gentle, steep) slopes.

Answer 5

gentle; steep
