1) Given: TAS = 200 kt, Track (T) = 0730, W/V = 210/20kt. Calculate the HDG (0T) and GS.
2) Given: FL 350, Mach 0.80, OAT -55°C. Calculate the values for TAS and local speed of sound (LSS).
3) An aircraft at FL 120, IAS 200 kt, OAT -50 and wind component +30 kt, is required to reduce speed in order to cross a reporting point 5 MIN later than planned. Assuming flight conditions do not change, when 100 NM from the reporting point IAS should be reduced to:
4) An aircraft at FL 140, IAS 210 kt, OAT -50C and wind component minus 35 kt, is required to reduce speed in order to cross a reporting point 5 MIN later than planned. Assuming that flight conditions do not change, when 150 NM from the reporting point the IAS should be reduced by:
5) For a long-range four-jet aircraft in cruising flight, the optimum altitude and the lock-on altitude increase. The most cost-effective flight plan will consist of chosing cruising levels which increase during the flight in order to fly:
