5. Final planning On the day of the flight, recheck everything above, then finalise your planning. a. Obtain weather forecasts which cover the time of your intended flight. You will need aerodrome forecasts (TAFs) for your destination and possible diversions if they are published; otherwise use TAFs for nearby aerodromes. Obtain either a route forecast or an area forecast which covers the route, including significant weather, winds and temperatures. Study actual reports (METARs) to check and update the forecasts. All of these are available on the UK Met Office web site. Check the local weather visually. b. If the forecast (adjusted by actual reports) suggests that cloudbase will be lower than your planned minimum, cancel or delay the flight. Check the crosswind components on the most likely runways at your destination and possible diversions. If the forecast crosswind is greater than your or the aircraft‟s capabilities, cancel or delay the flight. c. Using the forecast winds and temperatures for your planned altitude and time, finalise the navigation calculations. You may have to interpolate between different forecast levels. If making a long climb, use the wind and temperatures forecast for 2/3 of the way up the climb. Write the winds and temperatures you intend to use on the log. Decide and note your IAS. Make rough MDR heading calculations, then use a computer for detailed figures, and adjust for variation. Calculate groundspeed, then time and fuel required for each leg, and timings to each fix. Write down the fuel remaining at the end of each leg, and check that the total fuel required (including a safety margin) is less than the fuel load you intend carrying. Compare your final figures with your previous estimates; if the difference is great without an obvious reason, check them again. d. Make a final check of your planning by cross-referring between your log and your chart. You may wish to write headings and timings onto the chart, and a wind arrow with windspeed and maximum drift. At each turning point, visualise the amount of turn you are going to make (a protractor error can be spotted at this stage) and the features you will see. Remind yourself of your fix points, and how to find your start point. e. Complete the ATC flight plan form if required and submit it more than 60 minutes before start-up. Ensure ATC can contact you if there is a problem. f. Complete take-off and landing performance calculations. If you need more than the distances available after taking all safety factors into account, cancel or delay the flight. g. Make a final check by telephone to NATS AIS, or a last minute check on their website, that no temporary restricted or controlled airspace will affect your flight. h. If taking off from an aerodrome with an air traffic service unit, you may need to telephone your intended departure details. Brief a friend at your UK destination to inform the nearest air traffic services unit if you do not arrive by the time your fuel has run out. www.rin.org.uk 5 Mar 2012
6. Aircraft completion a. Check the aircraft log for unservicabilities. Pack all necessary certificates. b. Pre-flight check the aircraft. Check visually that fuel tank contents agree with your intentions and expectations and refuel if necessary. Top up oil. c. Weigh all baggage. If within the figures used in the calculations, load and secure it in the places you had intended. If too heavy, leave something behind. d. Brief passengers on safety, evacuation, and how to help by looking out for other aircraft and ground features. e. Load the route into your GPS set if not already done. Check it for gross errors and activate it before take-off. f. Make sure any filed flight plan will be activated once airborne. g. Check compass deviation card and alter planned headings if necessary h. Wear life preservers if flying over water. i. Finally check your log, map and all charts are in the cockpit and handy. Have a safe flight! www.rin.org.uk 6 Mar 2012
