## How is the maximum elevation figure calculated?

MEFs are determined by taking the highest of the following: 1) The point of highest terrain within a quadrangle, adding 200 ft for obstacles which are not required to be portrayed, and then adding 100 feet for vertical error and then rounding up to the next hundred feet; or 2) The height of the highest manmade obstacle …

### Where is the elevation on a sectional chart?

4 Answers. Simply check the scale, that already tells you it’s 2000-3000 feet. Then look for contour lines, there aren’t any, then it’s 2000-2500 feet.

**What does maximum elevation mean?**

The maximum elevation should represent the highest altitude in meters or feet, above or below sea level, at which the Site is found. …

**Is the maximum elevation figure in MSL?**

On VFR sectional charts the Maximum Elevation Fig- ure (MEF) gives pilots an obstruction-free altitude. These altitudes are then adjusted upward between 100 to 300 feet. On the VFR sectional in figure 1 the MEF is 9,700 feet mean sea level (msl). The highest peak within this quadrangle is (highlighted) 9,396 feet msl.

## 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 an Oroca?

Definition of OROCA. Instrument Procedures Handbook. An off-route obstruction clearance altitude (OROCA) is an off-route altitude that provides obstruction clearance with a 1,000-foot buffer in non- mountainous terrain areas and a 2,000-foot buffer in designated mountainous areas within the United States.

**How do you read a sectional map?**

**What are the large numbers on sectional chart?**

The Maximum Elevation Figure shows up on a sectional chart as a large number with a slightly smaller number next to it as illustrated in the image above with the red circle. These numbers have two digits dropped off of the end, so [large] 2 [small] 6 is 2,600 feet.

## How do you calculate elevation gain?

DISTANCE TRAVELED = the amount of distance you walk that registers on the treadmill console almost always reads as miles (mi) or kilometers (km). ELEVATION GAINED = the calculation of height [feet (ft), meters (m), miles (mi), or kilometers (km)] you would climb on a hike if the treadmill were a hill or mountain trail.

### Whats the difference between Max elevation and elevation gain?

Total Ascent provides a total of all increases to elevation (also known as elevation gain). Average Ascent provides an average of all ascents recorded during an activity. Maximum Elevation provides the highest elevation achieved.

**How do you read the elevation on a sectional chart?**

One of the most important is the Maximum Elevation Figure (MEF), a number found in each quadrant of the sectional chart. The MEF of a quadrant represents the highest elevation of any terrain or man-made features in the quadrant. The MEF represents the highest elevation of any terrain or man-made features in a quadrant.

**What is AGL on a sectional chart?**

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. On a Sectional Chart, all of the numbers you see that denote altitudes are denoted in MSL, unless they are in parentheses.

## What is the maximum elevation on a sectional chart?

The Maximum Elevation Figure shows up on a sectional chart as a large number with a slightly smaller number next to it as illustrated in the image above with the red circle. These numbers have two digits dropped off of the end, so [large] 2 [small] 6 is 2,600 feet.

### What is MEF (maximum elevation figure)?

Maximum elevation figure ( MEF) is a type of visual flight rule (VFR) information that indicates the elevation of the highest geographical feature within a GEOREF quadrangle area.

**How is maximum elevation calculated on a map?**

Every half of a degree of latitude and longitude have a Maximum Elevation Figure illustrated on the map, every degree of latitude and longitude has 4 Maximum Elevation Figures calculated based on Terrain and Manmade objects. MEF is calculated using the Mean Sea Level (MSL) elevation on a chart.

**What do the numbers on a sectional mean?**

One of the most important numbers on a sectional is the Maximum Elevation Figure, or MEF. The MEF depicts the lowest altitude you can fly and still be assured to clear every obstacle within that quadrant. MEF’s are calculated two ways, one for natural obstacles, and one for man-made obstacles.
