Preliminary Take Off Weight Built-up for Manned Aircraft Solution

STEP 0: Pre-Calculation Summary

Formula Used

Desired Takeoff Weight = Payload Carried+Operating Empty Weight+Fuel Weight to be Carried+Crew Weight
DTW = PYL+OEW+FW+W_c
This formula uses 5 Variables

Variables Used

Desired Takeoff Weight - (Measured in Kilogram) - Desired Takeoff Weight (or mass) is the weight of the aircraft.
Payload Carried - (Measured in Kilogram) - Payload Carried (passengers and cargo) is the object or the entity which is being carried by an aircraft or a launch vehicle.
Operating Empty Weight - (Measured in Kilogram) - Operating Empty Weight of the aircraft is the aircraft's weight without including passengers, baggage, or fuel.
Fuel Weight to be Carried - (Measured in Kilogram) - Fuel Weight to be Carried is defined as the total mass of the fuel to be carried (usually includes reserve fuel).
Crew Weight - (Measured in Kilogram) - Crew Weight is the weight of staff which are required for the functioning of the plane. It contains the weight of Pilots, flight engineer, navigation pilot and airplane staff to serve the passengers.

STEP 1: Convert Input(s) to Base Unit

Payload Carried: 12400 Kilogram --> 12400 Kilogram No Conversion Required
Operating Empty Weight: 125000 Kilogram --> 125000 Kilogram No Conversion Required
Fuel Weight to be Carried: 100000 Kilogram --> 100000 Kilogram No Conversion Required
Crew Weight: 12600 Kilogram --> 12600 Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

DTW = PYL+OEW+FW+W_c --> 12400+125000+100000+12600

Evaluating ... ...

DTW = 250000

STEP 3: Convert Result to Output's Unit

250000 Kilogram --> No Conversion Required

FINAL ANSWER

250000 Kilogram <-- Desired Takeoff Weight

What is maximum takeoff weight MTOW?

An aircraft has a range of weights from minimum to maximum depending upon the number of pilots and crew, fuel, and payloads (passengers, loads, luggage, and cargo). As the aircraft flies, the fuel is burning and the aircraft weight is decreasing. The most important weight in the design of an aircraft is the maximum allowable weight of the aircraft during take-off operation. This is also referred to as the all-up weight. The design MTOW is the total weight of an aircraft when it begins the mission for which it was designed. The maximum design take-off weight is not necessarily the same as the maximum nominal take-off weight, since some aircraft can be overloaded beyond design weight in an emergency situation, but will suffer reduced performance and reduced stability. Unless specifically stated, MTOW is the design weight. It means every aircraft component (e.g., wing, tail) is designed to support this weight.
