Navigation Log

The NavLog is set up like a standard paper log and provides route data of your selected flight. Select the entire route in the Enroute view to include alternate airport information.

See Nav Log Fuel Calculations for explanations of the different fuel fields and how their values are derived.

To view the navigation log, click the NavLog tab. Change the Nav Log format and show or hide optional blocks from the right-click menu.

What does MORA Mean in the NavLog?

In the Navigation log, MORA is displayed in parenthesis under MEA. When an MEA is not present with a waypoint, JIFP uses the Grid MORA where the waypoint resides. The Grid MORAs provide an obstacle clearance altitude within a latitude and longitude grid block, usually one degree by one degree. On Jeppesen charts, all MORA altitudes which are 6000 feet or lower have an obstacle clearance of 1,000 feet. If the MORA altitudes are 7,000 feet or greater, the obstacle clearance is 2,000 feet.
