A Flashcards
A1
When should an aircraft be re-Weighed?
After an extensive repair alteration that could change its weight or center of gravity.
A2
Why is it necessary to consider the category under which an aircraft is licensed when computing its weight and balance?
Different categories under which an aircraft can be licensed have different maximum gross weights and different center of gravity ranges.
A3
Where do you find the leveling means that are specified for a particular aircraft?
In the type certificate data sheets for the aircraft.
A4
What is meant by Tare weight when an aircraft is weighed.
The weight of any chokes and other items that are used to hold the aircraft on the scales.
A5
What must be done with tare weight when an aircraft is Weighed?
It must be subtracted from the scale readings to find the weight of the aircraft.
A6
Why are the distances of all the items installed in an aircraft measured from the Datum when computing weight and balance?
This makes it possible to find the point which the aircraft would balance (The center of gravity).
A7
Which has the more critical center of gravity range, and airplane or helicopter?
A helicopter.
A8
What is included in the empty weight of an aircraft?
The weight of the airframe, engines, and all items of Operating equipment that have fixed locations and I permanently installed in the aircraft. Empty weight includes optional and special equipment, fixed ballast, full reservoirs of hydraulic fluid and engine lubricating oil, and usable fuel.
A9
Where is the maximum allowable gross weight of an aircraft found?
In the type certificate data sheet for the aircraft.
A11
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.
A13
What must be done with temporary ballast when Weighing an aircraft?
It must be removed from the aircraft.
A14
What must be done to find the empty weight of an aircraft if it has been weighed with fuel in It’s tanks.
The weight of the fuel and it’s moment must be subtracted from the weight in the moment of the aircraft as it is weighed.
A15
What is meant by minimum fuel as it is used in the computation of aircraft weight and balance.
No more fuel in the quantity necessary for 1/2 hour of operation at rated maximum continuous power. It is the maximum Amount of fuel.used in weight and balance computations when low fuel may adversely affect the most critical balance conditions
A16
What is meant by the maximum zero fuel weight of an aircraft?
The maximum permissible weight of a loaded aircraft (passengers, cargo, etc.) Less its Fuel.
A17
What is meant by undrainable fuel ?
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 strainer. This is also called residual fFuel.
