In each blank, try to type in the
word that is missing. If you've
typed in the correct word, the
blank will turn green.
If your not sure what answer should be entered, press the space bar and the next missing letter will be displayed. When you are all done, you should look back over all your answers and review the ones in red. These ones in red are the ones which you needed help on. Question: Where must a record be kept of the current empty weight and the center of gravity of an aircraft?
Answer: In the flight manual or weight and balance records required by 14 CFR §23.1583.
Question: What is meant by the that is used for weight and balance computations?
Answer: A readily identified reference chosen by the aircraft from which all longitudinal locations on the aircraft are referenced.
Question: Why are the distances of all of the items installed in an aircraft measured from the when computing weight and balance?
Answer: This makes it possible to find the point about which the aircraft would balance (the center of ).
Question: What are two reasons weight and control are important in an aircraft?
Answer: For safety of and for most efficient performance of the aircraft.
Question: What is meant by moment in the of weight and balance?
Answer: A force that tends to cause rotation. It is the product of the weight of an object in pounds and the distance of the object from the in inches.
Question: How do you find the of an item that is installed in an aircraft?
Answer: Multiply the weight of the item in by its distance from the datum in inches.
Question: What is meant by the arm of an item that is installed in an ?
Answer: The distance, in inches, between the center of of the item and the datum.
Question: Why must we consider the under which an aircraft is licensed when we compute its weight and balance?
Answer: The different categories under which an aircraft can be licensed have different maximum gross weights and different of gravity ranges.
Question: Where can you find the leveling means that are specified for a particular ?
Answer: In the Type Certificate Data for the aircraft.
Question: Where is the arm of an item installed in an recorded?
Answer: In the Type Certificate Data Sheets for the .
Question: What must be done to find the empty of an aircraft if it has been weighed with fuel in its tanks?
Answer: The weight of the fuel and its must be subtracted from the weight and moment of the aircraft as it was weighed.
Question: What is meant by the tare weight that is used in a and balance computation?
Answer: The weight of the chocks and other items that are used to hold the on the scales.
Question: What must be done to the tare weight when an aircraft is ?
Answer: It must be from the scale reading to find the weight of the aircraft.
Question: What is meant by minimum fuel as is used in the of aircraft weight and balance?
Answer: No more fuel than the quantity necessary for one-half hour of operation at rated maximum continuous power. It is the amount of fuel used in weight and balance computations when low fuel may adversely affect the most critical balance conditions.
Question: What is by the maximum zero fuel weight of an aircraft?
Answer: The maximum permissible weight of a aircraft (passengers, crew, cargo, etc.), less its fuel.
Question: What is by undrainable fuel?
Answer: The fuel that is left in the tank, lines and components when the aircraft is placed in level flight position and the fuel drained at the main fuel . This is also called residual fuel.
Question: Describe the way you would find the empty and empty weight center of gravity of an airplane if there are no weight and balance records available.
Answer: The is weighed, and the empty weight center of gravity is computed. These values are recorded in new weight and balance records that are started for the aircraft.
Question: What is meant by permanent ballast for an ?
Answer: Weight that is permanently installed in an aircraft to bring the empty weight of gravity into allowable limits.
Question: Which has the more critical center of gravity , an airplane or a helicopter?
Answer: A helicopter.
Question: What equipment must be in an aircraft when it is weighed to find its empty weight center of gravity?
Answer: All of the equipment that is in the Aircraft Equipment List as "required equipment" or as equipment that is permanently installed.
Question: . What is the significance of the empty weight center of gravity of an aircraft?
Answer: If the empty weight center of gravity falls within the EWCG , the aircraft cannot be legally loaded in such a way that its loaded center of gravity will fall outside of the allowable loaded CG range. Not all aircraft have an EWCG range.
Question: Why is empty weight center of gravity range not in the Type Certificate Data Sheets for some aircraft?
Answer: The empty weight center of gravity range is given only for aircraft that cannot be legally loaded in such a way that their loaded center of will fall outside of the allowable limits.
