Review of FLIP and FAA Publications

Distance boxes,

, shown on Jet Routes, depict distances between NAVAIDs and/or between

J35

reporting points. Distances between fixes on “Direct” legs, or distances along only a portion of a Jet Route

segment, can be measured by using a straight edge, marking off the distance, and applying the marked off

distance to the convenient 250-nm scale at either the top or bottom of your particular chart. The scale is

divided into 50-nm increments, with one increment subdivided into 5-nm increments. Some mileages are

provided between other than reporting points, which are NOT in boxes.

Many times, the paths of two or more jet routes will coincide on the chart with the J being printed only

once:

You should file for the jet route which extends farthest along your planned profile of flight.

The High Altitude Charts depict the jet route system - 18,000 ft MSL through flight level 450, which is

contained within Class A airspace; therefore, all MINIMUM EN ROUTE ALTITUDES (MEAs) are 18,000 ft

MSL unless depicted as higher on a route segment.

MAXIMUM AUTHORIZED ALTITUDE (MAA) is depicted on a route segment when lower than FL 450.

MAA-31000

J584

MAA assures adequate NAVAID signal reception for the entire route segment of a designated jet route,

that is, it prevents co-channeling interference. Flights above the MAA must be filed as “DIRECT.”

A route “segment” may extend:

1. Between NAVAIDs

2. Between a NAVAID and an endpoint, which is a DME fix depicted by a vertical black line across

the route

199

3. Between two endpoints

J180

Unless designated by a MINIMUM CROSSING ALTITUDE (MCA), climbs and descents are commenced

where the segment begins or ends with obstruction clearance based on standard climb rates.
