Complete EMERGENCY "BINGO" TO ALTERNATE Section 2.1.8.4.1
This section of the jet flight log contains spaces for computing your total fuel required to the alternate
IAF--that is, for the total fuel required to cruise from destination to alternate, execute an approach, land,
and comply with OPNAVINST 3710.7 fuel reserve planning requirements.
We compute this section using three different scenarios on the lines provided:
The first assumes that the ARTCC clears you to contact your destination Approach Control without
clearing you to descend. Prior to switching to Approach, you dial in ATIS and discover your destination
has gone below minimums. You check your fuel gauge against the fuel required on your fuel plan and
determine that you have sufficient fuel to go to your alternate at your cruising altitude.
The second scenario has the ARTCC clearing you to contact Approach Control and descend to the IAF
altitude. Again, dialing in ATIS, you discover your destination has gone below minimums. At the IAF
altitude, you check your fuel available against the fuel plan, determine that you have sufficient fuel to
proceed to your alternate at the IAF altitude, and ask for the appropriate clearance without climbing back
to altitude. In computing this fuel, remember to use the appropriate TAS and Fuel Flow at your IAF
altitude. This also may require using different winds.
Finally, at your destination, the weather is marginal but still above minimums. Having sufficient fuel, you
file to your alternate in the event of missed approach and shoot the approach. Due to variable conditions,
you do not break out and decide to proceed to your alternate. Using your Bingo profile kneeboard card,
you determine the amount of fuel required (and the appropriate altitude) from the missed approach point to
the alternate IAF (or directly to the alternate airfield if in extremes). As the bingo card fuel card
INCLUDES reserve but not approach fuel, this need not be added to this figure. This computation is done
without wind as you will be climbing and/or descending most of the way.
Complete LAST CRUISING ALT Line
The first line corresponds to fuel from destination IAF to alternate IAF at flight-planned cruising altitude.
Complete INITIAL ALT Line
The second line corresponds to fuel from destination IAF to alternate IAF at the altitude/flight level
depicted for the destination IAF on the appropriate instrument approach procedure chart.
Complete EMER SAFE ALT Line
The third line corresponds to fuel from destination missed approach point (MAP) to alternate airfield using
a bingo profile as specified by the T-45A NATOPS Flight Manual.
