awareness, reduce heads down time and increase safety.” They highlight ten main bullet points of the redesign. Other minor changes were incorporated, as well (as noted elsewhere in this article).
  Topography: Color-coded topographical information is now included. The depiction is similar to that of Jepp approach plates, using a muted color palette that clearly distinguishes rising terrain without interfering with the readability of overlying critical data, such as altitude restrictions and course information. Large or prominent bodies of water are also shown. A chart Contour Intervals Scale is also depicted, when multiple elevation contours dictate. As on Jepp approach plates, the highest point on the chart (be it a man-made obstruction or natural terrain) is depicted using a bold, black, high-point arrow.
  Grid Minimum Off-Route Altitudes (Grid MORAs): A subtle grid of latitude/longitude lines now cover the charts similar to what instrument pilots are used to seeing on enroute charts. Inside each rectangle making up the grid is a GREY number representing the minimum off-route altitude within that sector (in hundreds of feet). This altitude should ensure 1,000-feet of vertical separation from obstacles and terrain (2,000-feet in mountainous areas).
  Altitude Restrictions: For easier and quicker identification, altitude restrictions are now color-coded BLUE and use a less cluttered format to represent
Figure 3: Seattle Tacoma International’s (KSEA) HAWKZ4 RNAV Arrival displays most of Jepp’s major formating changes in a single chart. Blue altitude restrictions exist
in minimum, between, and mandatory versions. Several magenta speed restrictions are displayed, as well as multiple MSA sectors (also in magenta). Terrain and water features,
the scale bar and areas drawn NOT TO SCALE are obvious, as well.
mandatory, minimum, maximum or recommended altitudes. Gone are the words “At,” “At or Below,” “At or Above,” “Between” and “Recommended,” and they are replaced by the same ICAO- standardized symbology utilized in Jepp approach plate profile views. A line above and below an altitude indicates a mandatory altitude, while a line above or below represents at/above (minimum) or at/below (maximum) altitudes, respectively. Altitude windows (between altitudes) are depicted with stacked top and bottom altitudes sandwiched between minimum and maximum lines. Recommended altitudes are presented without minimum or maximum lines. Altitudes to be expected or as assigned by ATC are still presented using adjacent “EXPECT” or “or by ATC” notations (Figure 3 and Table 1).
  Speed Restrictions: For easy reference and to avoid confusion
