CHAPTER SIX
INSTRUMENT FLIGHT RULES WORKBOOK
Step 5: COMPUTE CLIMB TAS USING CR-2, 3, 4, OR 5.
1.
Compute average altitude for climb (round to nearest 500 feet)
2.
Departure elevation plus cruise altitude divided by two
DEP FIELD ELEV + CRUISE
2
Step 6: COMPUTE CRUISE TRUE AIRSPEED (TAS) USING CR-2, 3, 4, OR 5.
Step 7: COMPUTE TIME TO CLIMB.
1.
Subtract starting altitude from cruise altitude.
2.
Round to nearest 100 feet and divide by rate of climb.
3.
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.
1.
Rules for leg entries on the Flight Log:
a.
NAVAID to NAVAID, on and off airways;
b.
Course changes of 6º or more on Victor Airways;
c.
Both ends of a direct route - anytime aircraft is not on an airway;
d.
Any mandatory reporting point.
2.
Fill in the NAVAID, magnetic course, and distance:
a.
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.
b.
To determine magnetic course and distance on a direct leg:
3.
Measure courses and distances directly off the charts. Use the compass rose for
course and mileage scale for distance.
