INSTRUMENT FLIGHT RULES WORKBOOK

Step 5: COMPUTE CLIMB TAS USING CR-2, 3, 4, OR 5.

Compute average altitude for climb (round to nearest 500 feet)

Departure elevation plus cruise altitude divided by two

DEP FIELD ELEV + CRUISE

Step 6: COMPUTE CRUISE TRUE AIRSPEED (TAS) USING CR-2, 3, 4, OR 5.

Step 7: COMPUTE TIME TO CLIMB.

Subtract starting altitude from cruise altitude.

Round to nearest 100 feet and divide by rate of climb.

Round time to nearest whole minute.

Step 8: DETERMINE YOUR CLIMB AND CRUISE FUEL FLOW USING THE FUEL

FLOW CHART (Figure 24-17) IN YOUR NATOPS MANUAL.

NOTE

For problems and test, this calculation has been done for you.

Step 9: REVIEW ROUTE OF FLIGHT AND RECORD EACH LEG ON FLIGHT LOG.

Rules for leg entries on the Flight Log:

NAVAID to NAVAID, on and off airways;

Course changes of 6 or more on Victor Airways;

Both ends of a direct route - anytime aircraft is not on an airway;

Any mandatory reporting point.

Fill in the NAVAID, frequency, magnetic course, and distance:

Magnetic course and distance from the departure airfield to the first fix

(INTERSECTION OR NAVAID) on an airway may be found in 1) the Enroute

Supplement in the NAVAIDs section of some airports; or, 2) on appropriate

Approach Plates as Enroute/Feeder Fixes. In the absence of these two sources,

3) measure the distances directly off the Low Altitude Charts and compare to

mileage scale, and use a nearby compass rose on the chart to measure the

course.

To determine magnetic course and distance on a direct leg:

Measure courses and distances directly off the charts. Use the compass rose for

course and mileage scale for distance.
