FAQ: What Is Cpt On Sectional Chart In Aviation?

Are sectional charts MSL or AGL?

Sectional charts normally show both mean sea level ( MSL ) and above ground level ( AGL ) heights for towers. Next to the tower, you’ll see two numbers. The top number is the height in MSL and the bottom number — in parentheses — is the height of the tower in AGL.

What is the scale of a sectional chart?

Sectional Charts have a scale of 1:500,000 (1 inch = 6.86 nautical miles (NM) or approximately 8 statute miles (SM)) and are very commonly used.

Is MEF AGL or MSL?

Flight Planning When planning your flight remember that the MEF and OROCA are listed in msl and ceilings are in agl.

What’s the difference between MSL and AGL?

Above Ground Level, or AGL, describes the literal height above the ground over which you’re flying. Mean Sea Level, or MSL, is your true altitude or elevation. It’s the average height above standard sea level where the atmospheric pressure is measured in order to calibrate altitude.

Is Class C AGL or MSL?

Class C airspace is generally airspace from the surface to 4,000 feet above the airport elevation (charted in MSL ) surrounding those airports that have an operational control tower, are serviced by a radar approach control, and have a certain number of IFR operations or passenger enplanements.

How long is a sectional chart valid for?

The aeronautical information on Sectional Charts includes visual and radio aids to navigation, airports, controlled airspace, restricted areas, obstructions, and related data. These charts are updated every six months, most Alaska Charts annually.

What does VFR stand for?

Aircraft flying in the National Airspace System operate under two basic categories of flight: Visual Flight Rules ( VFR ) and Instrument Flight Rules (IFR).

What is the lowest you can fly?

Low flying rules in the US An aircraft must maintain an altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or structure.

What is the lowest altitude you can fly?

The Federal Aviation Regulation (FAR) Part 91.119 indicates that, except when necessary for departure or landing, the minimum altitude over urban areas is 1,000 feet above ground level (AGL) and 500 feet AGL over rural areas.

What are the minimum safe altitudes?

91.119 Minimum safe altitudes; general (b) Over congested areas – Over any congested area of a city, town, or settlement, or over any open-air assembly of persons, an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft.
