Perform Weight And Balance 2 Flashcards
What is meant by the arm of an item installed in an aircraft?
The distance, in inches, between the center of gravity of the item and the datum.
Where do you find the arm of an item installed in an aircraft?
In the Type Certificate Data Sheets for the aircraft.
What is meant by the center of gravity range?
The distance in inches between the forward allowable center of gravity and the rearward allowable center of gravity.
What is the significance of the empty weight center of gravity range of an aircraft?
If the empty weight center of gravity range is given only for aircraft will fall outside of the allowable limits.
What is meant by the mean aerodynamic chord (MAC)?
The chord of an imaginary airfoil that has the same aerodynamic characteristics as the actual airfoil.
What is a loading envelope?
The enclosed area on a graph of an airplane’s loaded weight and CG location. If lines drawn from the weight and CG cross within this envelope is properly loaded.
What is meant by permanent ballast for an aircraft?
Weight that is permanently installed in an aircraft to bring the empty weight center of gravity into allowable limits.
Where must a record be kept of the current empty weight and the current center of gravity of an aircraft?
In the aircraft flight manual or weight and balance records required by 14 CFR 23.1583
