round 12.6 up and enter 15 in our LEG FUEL column. The EFR is simply the previous EFR

minus our current leg fuel.

Figure 1-13 Jet Flight Log Leg Fuel

In Figure 1-13, the top part of the jet log is complete. Note the purpose of the split DIST and

ETE blocks is now apparent. They give the mileage and time remaining to the IAF in the flight

from any one of the enroute navigational checkpoints.

At the IAF of our destination, we have zero miles and zero minutes to go, thus time remaining

starts here and works backwards. When the totals are computed, enter them in the manner

shown in the example. These numbers have more significance in later sessions.

In the NOTES column, you may write whatever you feel is helpful. It is recommended, at a

minimum, you list your predicted GS and crab angle for that particular leg of flight.

When completing your jet log remember:

Route description in the ROUTE TO column not only includes the aforementioned points

(i.e., L/O, DP/SID TERMINATION POINT), but also:

DP/SID TRANSITION POINT where specified enroute phase begins.

ALL NAVAIDs (VOR/TACAN/NDB) you MARK-ON-TOP of on your route of

flight.

Any named or unnamed fix defining your route of flight.

All points where a course change of 7 or more is required.

2. Ensure all fixes are annotated with radial and DME defining that fix (i.e., ENSLY NPA

340027).
