The length of each "spoke" around the circle is related to the frequency of time that the wind blows from a particular direction. Presented in a circular format, the wind rose shows the frequency of winds blowing from particular directions. Thus the OEW + payload isġ60,000 lb.A wind rose gives a succinct view of how wind speed and direction are typically distributed at a particular location. TheīRGW of 235,000 lb is now the limiting factor and reducing factor. The fuel capacity is not the limiting factor anymore. This extended ranges effects the most right part of the graph on page 34 moving it the range with 75550 lb of fuel was 4600 nm and will go toĤ904 nm. the fuel capacity goes upįrom 75,550 lb (page 9) to 80550 lb. This adds 180 pounds to the OEW, which becomes 137,120 lb. For this part the aircraft operator requested additional fuel tanks to be fitted in the 7 57 ’sįuselage. thus meaning the payload is: 153,00 0 – 136940 =ġ6,060 pounds equalling 73 passengers with baggage.Ĭ. OEW + payload can now only be 153,000 lb. With this flight pattern the fuel capacity of the 757 is the limiting factor. So again the graph on page 34 of the Boeing document is used to determine The distance of the trip is increased due to the fact that the aircraft is going to London Heathrow For this second part all the same steps are followed as above, however with the difference that However due to the two class layout this is limited to 186ī. the OEW isġ36,940 lb, if subtract this OEW from the OEW+payload the payload remains and is determinedĪt 51,060 lb equalling 232 passenger. This limits the OperatingĮmpty Weight (OEW) + payload to the maximum zero fuel weight of 188,000 lb. With a range of 1272 nm and aīRGW of 235000 lb the maximum zero fuel weight is the limiting factor. Now look to the graph on page 34 of the Boeing document. this OTW is the same as the Break Release Gross weight (BRGW). Information we use the graph on page 42 in the Boeing 757 document. HLE and ABJ is 1272 nm (Great Circle Mapper) and HLE has an elevation of 993 feet. Runway length of HLE in document about St. In this first part the payload has to beĬalculated for a unmodified 757 travelling from St, Helena (HLE) to Abijan (ABJ). For this assignment the task was to calculate the possible payload onboard off a Boeing 757 inĭifferent configurations, flight paths or weather conditions. Plotted in a radar-style image and will lead to the following wind rose:
Tailwind is a headwind which poses no real limit to aircraft operations. Number will be replaced with 10,000 (should be ∞ but that won’t work in excel) because a negative Was calculated by taking the cosine between the wind angle and the two different runwayĬonfigurations and afterwards multiplied with the tailwind limit. Was determined by taking the product of the crosswind ratio and crosswind limit. The crosswind limit for every particular wind angle Orientation and taking the absolute of the outcome (because the fact that the crosswind comingįrom left or right doesn’t making a difference). Ratio was determined by taking the sine of the angle between the wind direction and the runway First for every possible wind direction calculations were made to determine theirĬontribution to the crosswind and tailwind of aircraft landing on St. In this part of the assignment a wind rose had to be made for the airport of the British island St. Warning: TT: undefined function: 32 Assignment 6 Part 1 Summary - Chapter 6 "The Production and Trade Structure".Arresten Internationaal recht I - Samenvatting alle verplichten arresten week 1 t/m 3.College-aantekeningen, college 1-10 Beleid en Besluitvorming, Tentamenstof Compleet.Proef/oefen tentamen 16 oktober 2013, vragen en antwoorden.Een overzicht van de spieren van de bovenste extremiteit: naam, origo, insertie, functie, zenuw en arterie.Summary Money and Banking: book " The Economics of Money, Banking and Financial Markets, European Edition," Mishkin, Matthews, Giuliodori.Samenvatting Het Didactische Werkvormenboek - Hoofdstuk 1 - 7 en 11.Tentamen 28 maart 2013, vragen en antwoorden.Samenvatting inleiding groepsdynamica hoofdstuk 1-10.Samenvatting Grondtrekken van het Nederlandse Strafrecht Hoofdstuk 1- 16.Samenvatting Functieleer Boek Psychologie H1 + H3 t/m H10.Samenvatting Recht en samenleving in verandering R.J.S.
