Fuel, Weather, and Alternate Airfield Planning

MINIMUM FUEL REQUIREMENTS

FUEL PLANNING. All aircraft shall carry sufficient usable fuel, considering all meteorological

factors and mission requirements, to ensure:

(1) If alternate is not required, fly from takeoff to destination airfield IAF plus an approach plus a

reserve of ten percent of planned fuel requirements.

(2) If alternate is required, fly from takeoff to the approach fix serving destination and thence to an

alternate airfield plus a reserve of ten percent planned fuel requirements.

(3) In no case shall the planned fuel reserve after final landing at destination or alternate airfield,

if one is required, be less than that needed for 20 minutes flight, computed for turbine

powered, fixed wing aircraft based on maximum endurance operation at 10,000 ft.

(4) Minimum fuel reserve requirements are contained in the appropriate NATOPS manual.

The NATOPS performance data section provides charts to compute your fuel data. For convenience, this

information is consolidated in the Trawing One In-Flight Guide.

NAVIGATION COMPUTER

Introduction 2.1.10

The circular navigation computer has been designed to aid pilots in the solution of problems involving

flight, and primarily to compute time enroute and fuel required for a flight. The Navy uses various makes

and models, primarily the CR-2, 3 or 4 or the APN-91, but whether it be Jeppesen, Telex, Allegheny, or

one of several other makes, they are all either identical or similar in design. You have already been

exposed to this type of computer during the Schools Command and Primary phases of training.

Calculator Side

You should be fairly familiar with the calculator side, basically it's a circular slide rule that can be used for

time/distance/fuel computations (see your primary CR-2 workbook for review) but there is one more item

that it can be used for that has not been introduced up to now.
