12.9.5.11.1. OATC. Enter corrected outside air temperature as determined from the
appropriate performance manual.
12.9.5.11.2. VAR. Enter temperature variation from standard International Civil
Aviation (ICAO) temperature.
12.9.5.12. Block 12-HP. Enter the pressure altitude for the condition with altimeter set at
29.92 Hg.
12.9.5.12.1. For climb, enter HP for 2/3 the intended climb as soon as the altitude to
which the climb is to be made is known. The entry (2/3 HP) reflects pressure altitude
for 2/3 of the actual climb. If a climb starts at 15.000 feet and terminates at 30,000
feet, you compute the pressure altitude for 2/3 of the 15,000 difference, which is
10,000 feet. This HP added to the 15,000 foot beginning HP equals 25,000 feet HP,
which is the appropriate entry for this climb.
12.9.5.12.2. For cruise, enter the actual HP.
12.9.5.12.3. When descent exceeds 4,000 feet, blocks 10 through 18 need not be
completed.
12.9.5.13. Block 13-CRUISE CEILING. Enter 4-engine cruise ceiling for the aircraft
from the appropriate performance manual.
12.9.5.14. Block 14-CRUISE IAS. Enter indicated airspeed from the appropriate
performance manual required to maintain desired true airspeed.
12.9.5.15. Block 15-TORQUE. Enter torque value from the appropriate performance
manual required to maintain the desired true airspeed.
12.9.5.16. Block 16-3-ENGINE SERVICE CEILING. Enter 3-engine service ceiling
from the appropriate performance manual.
12.9.5.17. Block 17-3-ENGINE DRIFTDOWN IAS. Enter the 3-engine driftdown
indicated airspeed from the appropriate performance manual.
12.9.5.18. Block l8-ENGINE INST F/F LBS/HR. Enter the average individual fuel flow
reading and total for the period. Engine instrument fuel flow (lbs/hr) will be the complete
figure (4800 not 4.8).
12.9.5.19. Block 19-PERIOD (FUEL USED). Enter fuel used for engines for the period
as computed using total of fuel flow readings. NOTE: For fuel used during WU/TAXI,
use 50 pounds per minute. For fuel used during TAKEOFF, use 300 pounds. Enter all
fuel used, fuel remaining, and gross weights in thousands. EXAMPLE: 127,300 = 127.3.
All weights are to be carried to the nearest hundred. EXCEPTION: Engine instrument
fuel flow (lbs/hr) will be a complete figure.
12.9.5.20. Block 20-EXTRA (FUEL USED). Enter extra fuel used during flight
condition period for fuel jettisoning, APU, etc. Fuel transferred to a receiver during air
refueling will be entered in this block.
12.9.5.21. Block 21-TOTAL (FUEL USED). Enter cumulative total of fuel used for
successive conditions. This block represents all fuel consumed to END clock time
