FLIGHT TRAINING PUBLICATION (FLIP) STUDENT GUIDE
Distances between fixes on " direct" flights, 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 scale at the bottom or the top edge of the charts. This
scale is divided into 50-mile increments with a 50-mile scale divided into 5-mile increments.
Compulsory reporting points are those points indicated by solid triangles on the chart.
When not in radar contact, position reports are required at these points, or any points listed on
your Flight Plan (DD-17S) which define your route of flight. The format for these reports is
found on the back cover of the IFR Supplement. Rules for position reporting will be covered in
the Voice Communications classes.
Those NAVAID identification boxes on your chart that are shaded to appear three-dimensional
indicate a FSS is present with the same name as the NAVAID. Standard FSS frequencies are
listed in the legend with additional VHF frequencies printed above the identification box. FSSs
serving other areas can be found by looking under the name of a particular airport or NAVAID
in the IFR Enroute Supplement.
It is not possible to include all military and civil navigation and radio frequency information on
the panels of each chart in addition to the route data shown. All data pertinent to an airport is,
therefore, contained in the IFR Enroute Supplement. NOTAMS should be examined for updated
information prior to planning each flight.
In controlled airspace, including Special Use Airspace, ATC is responsible for clearing an
aircraft and maintaining legal separation from other known IFR traffic. In uncontrolled airspace,
ATC has neither the authority nor responsibility for the control of air traffic; it is the sole
responsibility of the Pilot-In-Command to obtain clearance prior to filing his flight plan. "No
A/G" will denote Special Use Airspace with no air-to-ground communication facility controlling
In this unit of instruction, we have discussed how the Jet Route system operates and how to
properly and accurately use the High Altitude Charts. The legend is broken down into four
