Useful load is the weight of the crew, passengers, baggage, usable fuel and drainable oil. Generally, this can be found by subtracting the basic empty weight from the maximum allowable gross weight. Station is the term used to define a specific location, determined from the reference datum, on the aircraft.
What is the useful load of an aircraft?
Useful load—the weight of the pilot, copilot, passengers, baggage, usable fuel, and drainable oil. It is the basic empty weight subtracted from the maximum allowable gross weight. This term applies to general aviation (GA) aircraft only.
How is aircraft payload calculated?
Subtract the basic empty weight and fuel from the maximum weight. Check the aircraft’s weight and balance sheet and find the maximum allowable gross weight of the aircraft. Then, find the basic empty weight value and subtract that from the max weight to get your “useful load” weight.
How is aircraft weight and balance calculated?
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.
Is useful load with fuel?
The useful load consists of fuel, any other fluids that are not part of empty weight, passengers, baggage, pilot, copilot, and crewmembers. … The payload of an aircraft is similar to the useful load, except it does not include fuel.
What is the difference between payload and useful load?
Useful Load – The difference between the gross weight and the basic empty weight is referred to as useful load. It includes the flight crew, usable fuel, drainable oil, if applicable, and payload. Payload – The weight of the passengers, cargo, and baggage. Gross Weight – Total of the basic empty weight and useful load.
Does aircraft empty weight include fuel?
Basic aircraft empty weight is the weight of the aircraft without passengers, baggage or usable fuel. … Fuel load is the expendable fuel in the aircraft; however, it does not include any fuel in fuel lines or tank sumps.
What is payload range?
There is a natural trade-off between the payload and the range of an aircraft. A payload range diagram (also known as the “elbow chart”) illustrates the trade-off. The top horizontal line represents the maximum payload. It is limited structurally by maximum zero-fuel weight (MZFW) of the aircraft.
What is the payload capacity?
A truck’s payload capacity refers to the maximum amount of weight you can safely add to a truck’s cargo area in addition to its empty weight (or curb weight). Towing capacity, on the other hand, refers to the maximum weight that a truck can tow after factoring in the weight of the truck and any cargo.
Why is it called payload?
In the context of a computer virus or worm, the payload is the portion of the malware which performs malicious action. The term is borrowed from transportation, where payload refers to the part of the load that pays for transportation.
How often does an aircraft need to 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.
Who is responsible for the correct weight and balance of every flight?
The pilot in command of the aircraft has the responsibility on every flight to know the maximum allowable gross weight of the aircraft and its CG limits. This allows the pilot to determine, on the preflight inspection, that the aircraft is loaded in such a way that the CG is within the allowable limits.
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.
What is full fuel payload?
Total up the gallons of fuel that can be burned, multiply by the weight per gallon (six pounds per gallon for avgas or 6.8 pounds for Jet A), and subtract that from the aircraft’s useful load. … The FAA definition is this: Payload is the weight of occupants, cargo, and baggage.
Why do airplanes have unusable fuel?
Unusable fuel is really a safety mechanism to ensure that the engine is properly fed fuel in all phases of flight. It’s not a reserve tank of any sort, although you can sometimes access this unusable fuel.
How do you calculate fuel weight?
Subtract the total amount of fuel you have on takeoff from the amount you will use during your flight. What will be your takeoff fuel weight? To calculate your takeoff fuel weight, multiply your takeoff gallons by the weight of fuel.
