Why it is important to follow step by step of weighing an aircraft?
The most important reason for weighing an aircraft is to find out its empty weight (basic empty weight), and to find out where it balances in the empty weight condition. When an aircraft is to be flown, the pilot in command must know what the loaded weight of the aircraft is, and where its loaded center of gravity is.
When should an aircraft be weighed?
When operating under FAR 135, an aircraft must be weighed every 36 calendar months to establish its current empty weight and center of gravity.
What are the equipment used in weight and balancing of an aircraft?
Two types of scales are typically used to weigh aircraft: those that operate mechanically with balance weights or springs, and those that operate electronically with what are called load cells.
What is included in basic empty weight?
Standard empty weight (GAMA)—aircraft weight that consists of the airframe, engines, and all items of operating equipment that have fixed locations and are permanently installed in the aircraft, including fixed ballast, hydraulic fluid, unusable fuel, and full engine oil.
What tasks are completed prior to weighing an aircraft to determine its empty weight?
What tasks are completed prior to weighing an aircraft to determine its empty weight? Remove all items except those on the aircraft equipment list; drain fuel and fill hydraulic reservoir. in the Aircraft Specification or Type Certificate Data Sheet.
Who is responsible for the correct weight and balance of every flight?
1-1] The pilot in command of the aircraft has the responsibility on every flight to know the maximum allowable weight of the aircraft and its CG limits.
How important is weight and balance in aircraft?
The Balance point (Centre of Gravity – CG) is very important during flight because of its effect on the stability and performance of the aircraft. It must remain within carefully defined limits at all stages of flight. … The structural strength of the aircraft also limits the maximum weight the aircraft can safely carry.
How does weight affect flight?
Weight is the force that pulls the plane down due to gravity. In order for the plane to get off the ground, the plane must overcome its weight throught the force of lift. The more mass the plane has the more lift it has to produce in order to get off the ground.
What is minimum fuel in aviation?
Minimum Fuel. … “Indicates that an aircraft’s fuel supply has reached a state where, upon reaching the destination, it can accept little or no delay. This is not an emergency situation but merely indicates an emergency situation is possible should any undue delay occur.”
What are the two most commonly used types of aircraft scales?
The two basic types of scales used to weigh aircraft are platform and load cell.
Does empty weight include unusable fuel?
Basic Empty Weight – The starting point for weight computations is the basic empty weight, which is the weight of the standard helicopter, optional equipment, unusable fuel, and full operating fluids including full engine oil. … It includes the flight crew, usable fuel, drainable oil, if applicable, and payload.
How do you calculate aircraft weight and balance?
Ascertain from the pilot’s operating handbook the empty weight of the aircraft and determine the weights of people, baggage, and fuel. Multiply each weight by the arm—the distance from the reference datum—to find the moment. Add all the weights to find the gross weight. Add all the moments to find the total moment.
How weight and balance affect the performance of an aircraft?
Weight and balance have a direct effect on the stability and performance of the aircraft. If a plane is too heavy, it may never get off the ground. If it’s out of balance, it may be uncontrollable when it does take flight. … Maintaining proper weight and balance is an extremely important balancing act.
How is CG calculated in aircraft?
Center of gravity (CG) is calculated as follows:
- Determine the weights and arms of all mass within the aircraft.
- Multiply weights by arms for all mass to calculate moments.
- Add the moments of all mass together.
- Divide the total moment by the total mass of the aircraft to give an overall arm.
