STEP 0: Pre-Calculation Summary
Formula Used
Payload = Zero fuel weight-Operating empty weight
Wpay = WZF-WOE
This formula uses 3 Variables
Variables Used
Payload - (Measured in Kilogram) - Payload of a passenger aircraft is the total weight of cargo plus additional passengers being carried in the airplane.
Zero fuel weight - (Measured in Kilogram) - Zero fuel weight (ZFW) is the weight of the aircraft with payload on board and empty fuel tanks.
Operating empty weight - (Measured in Kilogram) - Operating empty weight is the sum of the empty weight and the crew plus their baggage.
STEP 1: Convert Input(s) to Base Unit
Zero fuel weight: 16756 Kilogram --> 16756 Kilogram No Conversion Required
Operating empty weight: 453 Kilogram --> 453 Kilogram No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Wpay = WZF-WOE --> 16756-453
Evaluating ... ...
Wpay = 16303
STEP 3: Convert Result to Output's Unit
16303 Kilogram --> No Conversion Required

## Aerofoil Thickness for 4 Digit Series

Formula
("y"_{"t"}"X") = ("t"* ((0.2969*(("x")^(0.5)))- (0.1260*"x")- (0.3516*(("x")^(2)))+ (0.2843*(("x")^(3)))- (0.1015*(("x")^(4)))))/0.2

Example
"6.617532m"= ("15m"* ((0.2969*(("0.5")^(0.5)))- (0.1260*"0.5")- (0.3516*(("0.5")^(2)))+ (0.2843*(("0.5")^(3)))- (0.1015*(("0.5")^(4)))))/0.2

Calculator
LaTeX
Half Thickness = (Maximum Thickness* ((0.2969*((Position Along the chord)^(0.5)))- (0.1260*Position Along the chord)- (0.3516*((Position Along the chord)^(2)))+ (0.2843*((Position Along the chord)^(3)))- (0.1015*((Position Along the chord)^(4)))))/0.2

Formula
"TI" = (("DI"_{""min""}*100)-("WI"*"P"_{"w"})-("CI"*"P"_{"c"}))/"P"_{"t"}

Example
"15.52632"=(("16"*100)-("50"*"15.1")-("55"*"10"))/"19"

Period Index = ((Minimum Design Index*100)-(Weight Index*Weight Priority (%))-(Cost Index*Cost Priority (%)))/Period Priority (%)

Formula
"CI" = (("DI"_{""min""}*100)-("WI"*"P"_{"w"})-("TI"*"P"_{"t"}))/"P"_{"c"}

Example
"-96"=(("16"*100)-("50"*"15.1")-("95"*"19"))/"10"

Calculator
LaTeX
Cost Index = ((Minimum Design Index*100)-(Weight Index*Weight Priority (%))-(Period Index*Period Priority (%)))/Cost Priority (%)

Formula
"DI"_{""min""} = (("CI"*"P"_{"c"})+("WI"*"P"_{"w"})+("TI"*"P"_{"t"}))/100

Example
"31.1"=(("55"*"10")+("50"*"15.1")+("95"*"19"))/100

Calculator
LaTeX
Minimum Design Index = ((Cost Index*Cost Priority (%))+(Weight Index*Weight Priority (%))+(Period Index*Period Priority (%)))/100

Payload = Zero fuel weight-Operating empty weight
Wpay = WZF-WOE

The total number of passengers and weight of goods that an aircraft or a ship carries or can carry is defined a payload of the aircraft or of any other ship or carrier.

## How to Calculate Payload of aircraft?

Payload of aircraft calculator uses Payload = Zero fuel weight-Operating empty weight to calculate the Payload, Payload of aircraft is the weight of the load that you carry in aircraft for remuneration, like passengers, their luggage and/or cargo or the mass that is taken by an airplane, excluding fuel. Payload is denoted by Wpay symbol.

How to calculate Payload of aircraft using this online calculator? To use this online calculator for Payload of aircraft, enter Zero fuel weight (WZF) & Operating empty weight (WOE) and hit the calculate button. Here is how the Payload of aircraft calculation can be explained with given input values -> 16303 = 16756-453.
