How often are charts flight-checked
Generally every 4 years
Open Water
Lighter blue tone that shows the shoreline limitations of all coastal water features at mean high water levels for oceans and seas
Also includes connecting waters (bays, gulfs, sounds, fjords, large estuaries)
Inland Water
Darker blue tone that shows all other bodies of water that aren’t oceans, seas or associated waters
Are large lakes, such as the great lakes, considered “open water”
Yes
Oil wells on sectional charts
Small open circles
Water, oil, and gas tanks on sectional
Small black circles (labeled)
Man-made structures over what height are charted on sectionals?
200’ AGL, unless they appear in yellow city tint
When will objects less than 200’ AGL be charted?
If they are considered hazardous
Man-made structures at and over what height are charted on World Aeronautical Charts?
500’ AGL
How far apart are contour lines spaced
500’ intervals
250’ in moderately level or gently rolling areas
Shaded relief shows how terrain may appear from the air. Shadows are shown as if light is coming from what direction?
The Northwest
MEF
Maximum elevation figure
How is the MEF determined for man made objects?
Elevation of the obstacle, Add 100’ for possible vertical error, Round up to the next highest hundred foot level
How is the MEF determined for natural terrain features?
Elevation of obstacle, Add 100’ for possible vertical error, Add 200’ for obstacles not portrayed due to being below minimum chartable height, Round up to the next highest hundred foot level
Crosshatch over VOR frequency indicates what?
Shutdown status
What do the letters UC next to the height of and obstruction indicate?
Obstacle is under construction or
Reported but position/elevation is unverified
