Let's start at the top — Page 313, Lesson 304

I want to walk you through the Operational Flight Plan form that you see here. This is the core document you will use on every flight to plan, record, and monitor fuel, time, and progress. Let's start at the top. The form is headed "OPERATIONAL FLIGHT PLAN" and it is marked "FOR TRAINING AND EXAMINATION PURPOSES ONLY" — so this is a training example, but it follows the real format. At the very top left we have spaces for "FLT NR" (flight number), "ACFT TYPE" (aircraft type), "ACFT REG" (aircraft registration), and "SKED BLOCK TM" (scheduled block time — the planned time from chocks off to chocks on). On the right side of the top section we have "FROM-TO" — here it shows LFPG to EGLL, that's Paris Charles de Gaulle to London Heathrow. Below that we have "AVG WC" (average wind component), "AVG FF" (average fuel flow), and "TOC" (top of climb — the point where you reach your cruising altitude). Now look at the main body of the form. It is organised as a table with columns. The first column is "SEG" — that stands for segment, meaning each leg or phase of the flight. Then we have "FROM-TO" again for each segment, "FL" (flight level), "AVG TC" (average true course), "W/V" (wind velocity — direction and speed), "GS" (ground speed), "DIST" (distance), "TIME", and "FUEL". The last column is "INT FUEL" — that means the fuel remaining on board at the end of each segment, the integrated or cumulative fuel. Down the left side of the table, you see labels for the different phases. Starting from the top: "TAXI FUEL", then "TKOF FUEL" (takeoff fuel), then "TRIP FUEL", "CONT FUEL" (contingency fuel), "ALTN FUEL" (alternate fuel), "FINAL RES" (final reserve), "EXTRA FUEL", and "BLOCK FUEL" at the bottom. These are the standard fuel planning categories under regulations. Let me read the entries in the table so you see how it works. The first segment row shows "340 280/40" — that means flight level 340, wind 280 degrees at 40 knots. Then "ISA -10 °C" (temperature 10 degrees below International Standard Atmosphere), "280" (TAS — true airspeed), "0.74" (Mach number), then "X" marks for distance, time, and fuel — those are left blank in this training example. The INT FUEL column shows "M" — that likely stands for a calculated value or a marker. Further down we see "STEP CL" — step climb, meaning a climb to a higher flight level during cruise. Then "INT FUEL assumed 80" — that is a note that the integrated fuel at that point is assumed to be 80 units (probably kilograms or pounds, we need to check the units elsewhere). At the bottom of the table we have the alternate segment: "ALTN FL AVG TC W/V GS DIST TIME FUEL INT FUEL EGCC 330 250/30 M ADD DES X LM49,700KG M INT FUEL M ADD DES LM" — this is the alternate airport, EGCC (Manchester), at flight level 330, wind 250/30, and "ADD DES" means additional descent fuel. "LM49,700KG" is likely the landing mass — 49,700 kilograms. On the right side of the form there is a vertical list: "EST ZFM" (estimated zero fuel mass), "TIME", "TAS", "TOM" (takeoff mass), "CALC NAM ACC FUEL" (calculated name? or calculated navigation? — this is a fuel accounting line), "ACC" (accumulated), "C C A T N I A SI B M C FLT" — these are probably column headers for a fuel monitoring log, with "acc+CA* X" being an accumulated fuel plus correction factor. Below that we see "340 280/40 X ISA-10 °C 280 0.74 X X 50 50 M 280/40 ISA-10 °C 280 0.74 430 INT FUEL X 280/40 ISA-10 °C 280 0.74 M 00:41 320 280/40 X ISA-10 °C 280 0.74 X X STEP CL M INT FUEL assumed 80 M STEP CL M INT FUEL M STEP CL M INT FUEL M STEP CL M INT FUEL M STEP CL M INT FUEL M STEP CL M ALTN FL AVG TC W/V GS DIST TIME FUEL INT FUEL EGCC 330 250/30 M ADD DES X LM49,700KG M INT FUEL M ADD DES LM" — this is a repeated or alternative set of entries, possibly for a different scenario or a second leg. At the very bottom we have "FO_ PIC_" — spaces for the First Officer and Pilot in Command signatures. Then "APPENDIX C TO FP FEEDBACK" — this is a feedback form appendix. And "EST ALTOF BLOCK FUEL TOC ABB 116.5 TOD EGLL TAS GS DIST assumed 1750kg 1300kg PLN TO G + L - CMB ADDN * TC GC POSITION LFPG W/V WCA FL CRZ PROC" — these are additional planning fields: estimated altitude of the block fuel, top of climb, ABB (probably a waypoint or beacon frequency 116.5), top of descent at EGLL, true airspeed, ground speed, distance, assumed fuel values of 1750 kg and 1300 kg, "PLN TO" (plan to), "G + L -" (gross plus or minus?), "CMB ADDN" (climb addition), then position, wind velocity, wind correction angle, flight level, cruise procedure. The key takeaway here is that an Operational Flight Plan is a structured document that captures every phase of the flight — taxi, takeoff, climb, cruise, step climbs, descent, alternate, and reserves — with fuel, time, distance, and wind data for each segment. The INT FUEL column lets you track how much fuel you have left at each point, and the bottom summary gives you your block fuel (total fuel on board at engine start) and all the regulatory fuel categories. This is the document you will use to brief, fly, and monitor your fuel against the plan.
