T-45A UJPT, E2-C2 INav-09
Flight Planning (Departure)
Complete ETE Block
Enter your estimated time en route to the fix (normally to the nearest whole minute), using your expected
ground speed and distance.
The training squadrons do not use climb winds in jet aircraft. Refer to the T-45A Fuel Planning Data Card
in your In-flight Guide to read distance, time, and fuel required for the climb to altitude. Interpolate for
intermediate altitudes. Ground speed is computed utilizing the expected TAS from the fuel card, and
forecast winds aloft from your DD-175-1 as computed on your navigation computer.
NOTE: More precise computation will be required for those missions requiring target times or when fuel is
critical.
Figure 13 shows a completed ETE block.
Complete ETA/ATA Block During Flight
Enter your estimated time of arrival and log your actual time of arrival at a fix or checkpoint. Use these
numbers to compare your actual flight progress to your planned flight progress as you pass each fix.
Figure 14 shows an incomplete ETA/ATA block.
Complete LEG FUEL Block
Enter your estimated fuel required to fly each leg, using fuel flow and estimated time en route.
Fuel flow is derived from the fuel card, and interpolated for your cruising altitude. Always round UP to the
next higher ten pounds (e.g., 192# would become 200#).
Figure 15 shows a completed LEG FUEL block.
PROGRESS CHECK
Question 6 — 2.1.8
Your fuel flow at a cruise altitude of FL270 is 1052 pph and your true airspeed is 352 KTAS. Your
FLIP Enroute High Altitude Chart indicates 76 miles from one fix to the next. This leg of your
flight will take you _____ minutes and you will use _____ lb of fuel. For computations, assume
no wind condition. Round to the nearest whole minute and up to the next 10-pound increment of
fuel.
ANSWER:
Complete EFR/AFR Block
Enter your estimated fuel remaining during planning and log the actual fuel remaining during your flight.
Use this information to compare your actual fuel consumed to your planned fuel use as you pass each fix.
Figure 16 shows a completed EFR/AFR block.
