Chap4 AC Weighing And Balance Flashcards
What is essential for the safe operation of aircraft?
The weight and centre of gravity (CofG) must remain within specified limits at all times.
Who is responsible for ensuring the aircraft is correctly loaded?
The Aircraft Commander is responsible for ensuring correct loading and that weight and CofG are within prescribed limits.
How can the weight and CofG of an aircraft in flight be accurately determined?
They can only be accurately determined if the basic weight and CofG are precisely known in a specified unloaded condition.
Who determines the basic weight and CofG of each aircraft?
The Aircraft Design Organisation determines the basic weight and CofG before delivery to the MOD.
What can cause changes to the basic weight and CofG in service?
Modifications, repainting, replacement of major components, or structural repairs can cause changes.
When should aircraft be weighed?
Aircraft should be weighed periodically as detailed by the Type Airworthiness Authority.
What is one occasion when an aircraft must be weighed?
After a major modification programme.
When must an aircraft be weighed if the surface finish exceeds 25%?
When depth maintenance of an aircraft surface finish exceeds 25% of the surface area.
What events require weighing if the effect on weight and moment cannot be calculated?
Events include major single design modifications, multiple minor modifications, major repairs, and significant component replacements.
What must be done before weighing an aircraft?
The aircraft must be prepared according to the Aircraft technical instruction before the Weighing Team’s arrival.
Who is authorized to calculate and record aircraft weight and moment data?
Only authorized personnel are allowed to carry out the calculation and recording of aircraft weight and moment data.
