EMERGENCY "BINGO" TO ALTERNATE SECTION
The EMERGENCY BINGO section summarizes the flight profiles to your alternate airfield.
Figure 1-22 is the completed EMERGENCY BINGO section for this flight.

LAST CRUISING ALT - These numbers relate to your first alternate profile (i.e., cruising at
15,000 feet from destination IAF to alternate IAF). The 100 lbs is taken directly from the front
of the jet log, and the approach and reserve fuels are from the FUEL PLAN section.
INITIAL APP ALT - Your second alternate profile (i.e., at 5000 feet from destination IAF to
alternate IAF). The 110 lbs is taken from the front of the jet log. The approach and reserve fuels
are from the FUEL PLAN section. This alternate profile is planned at 5000 feet. In addition, the
round numbers it provides lessens the need for interpolation. For practical purposes, this is a
useful set of data, because frequently, your need to divert to an alternate is not known until you
are near the IAF, ready to commence an approach.
BINGO - In the REQUIRED column, write the altitude to which you are climbing. In the
APPROACH column, enter the IAS for the BINGO profile. In the RES column, enter the
descent point. In the TOTAL column, copy the IFR Bingo fuel you computed from the Bingo
chart (220 lbs in this case).
The arrows are simply visual cues you may use to remind yourself
of the climb ( ) and descent ( ).
The final sections of the jet log concern useful information you as an air crewmember should
know about your destination, alternate, and enroute emergency fields. It is mostly self-
explanatory, however, some useful hints follow:
RWY LENGTH - List the length and width of the runway on which you predict you
will land. Utilize the most precise information available (i.e., IFR Enroute
Supplement and/or Approach Plates).
