Simple interpolation for a flap angle of 30 degrees yields arunway length needed of 1,777 meters thus is rounded off to thenearest largest integer, say 1,800 m.Weight(kg.)72,000(72,500)74,000Elevation = 1000mts.1,765( ? )1,815R 0f = 30f= 1777.50 mR L0S30== 1,800 mVirginia Tech - Air Transportation Systems Laboratory 72
- f2520155II) Takeoff Analysisa) Recall the desired takeoff weight DTW = 82,396 kg.b) Verify all flap settings that will allow the aircraft to execute a safetakeoff.The following table illustrates all possible flap angle takeoffconfigurations for the Boeing 727-200.(Deg.) MTOW (kg) Check76,50081,80086,90089,400Note that the aircraft can use 3 flap settings at this elevation/payloadcombination. Therefore, 3 options for runway length requirementsneed to be investigated.NO aOKOKOKa.DTW is greater than the maximum allowable takeoff weight so do not consider.Virginia Tech - Air Transportation Systems Laboratory 73
