48Student Study Guide / Aircraft Basic Science27. For general weight-and-balance purposes the following weights are considered standard:a. Gasoline _______________________ lb/gal.b. Turbine fuel _______________________ lb/gal.c. Lubricating oil _______________________ lb/gal.d. Water _______________________ lb/gal.e. General aviation crew and passengers _______________________ lbf. Air carrier passenger (summer) _______________________ lbg. Air carrier passenger (winter) _______________________ lb28. The weight of the equipment necessary for weighing the airplane (such as chocks, blocks, slings, jacks, etc.), which is included in the scale reading but is not a part of the actual weight of the airplane, is called _______________________ weight.29. A vertical line passing through the center of the axle of the main landing gear wheel is the _______________________. 30. Tare weight must be _______________________ from the scale reading in order to obtain the actual weight of the airplane.31. The abbreviation for the trailing edge of the mean aerodynamic chord is _______________________. 32. The minimum fuel for weight-and-balance computations is no more than the quantity of fuel required for _______________________ hour of operation at rated maximum continuous power. It is calculated on the maximum except takeoff (METO) horsepower.33. _______________________ fuel is a part of the aircraft’s empty weight.34. The weight of the pilot, copilot, passengers, baggage, and usable fuel is called the aircraft’s _______________________. 35. The maximum allowable weight at the start of the takeoff run is called maximum _______________________ weight.36. The useful load is obtained by subtracting the _______________________ weight from the _______________________ weight.37. The CG and CG limits may be expressed in terms of a percentage of the _______________________ or in inches forward or to the rear of the _______________________.38. Normally, an aircraft will have acceptable flight characteristics if the CG is located somewhere near the _______________________ percent average chord point.39. The aircraft should be weighed inside a closed building to avoid errors that may be caused by _______________________. 40. An airplane must be in a _______________________ attitude to obtain accurate weighing information.41. Leveling an aircraft is usually accomplished along both the _______________________ and _______________________ axis.42. When a new weight-and-balance report is prepared for an aircraft, the previous report should be marked _______________________ and the date of the new document referenced.43. The weight of any item installed in the airplane is _______________________. 44. The weight of any item removed from the airplane is _______________________. 45. When items are added forward of the datum line, the signs are (___) weight ×(___) arm =(___) moment.46. When items are added to the rear of the datum line, the signs are (____) weight ×(___) arm =(___) moment.47. When items are removed forward of the datum line, the signs are (____) weight ×(___) arm =(___) moment.48. When items are removed to the rear of the datum line, the signs are (___) weight ×(___) arm =(___) moment.49. The most important performance deficiencies of an overweight airplane are:a. _________________________________________________________________________b. _________________________________________________________________________c._________________________________________________________________________d. _________________________________________________________________________e. _________________________________________________________________________f. _________________________________________________________________________g. _________________________________________________________________________h. _________________________________________________________________________
Chapter 7 / Study Questions4950. When too much weight is toward the forward part of the airplane, the center of gravity is shifted forward and any one of the following conditions may exist or they may occur in combination:a. _________________________________________________________________________b. _________________________________________________________________________c. _________________________________________________________________________d. _________________________________________________________________________e. _________________________________________________________________________f. _________________________________________________________________________g. _________________________________________________________________________51. When too much weight is toward the tail of the airplane, any one of the following conditions may exist or they may occur in combination:a. _________________________________________________________________________b. _________________________________________________________________________c. _________________________________________________________________________d. _________________________________________________________________________e. _________________________________________________________________________
