The Monarch Butterfly has a very low 0.168 kg/m 2 wing loading The McDonnell Douglas MD-11 has a high 837 kg/m 2 maximum wing loading. In aerodynamics, wing loading is the total weight of an aircraft or flying animal divided by the area of its wing.
The A380 is offered with the Rolls-Royce Trent 900 (A380-841/-842) or the Engine Alliance GP7000 (A380-861) turbofan engines. [153] The Trent 900 is a combination of the 3 m (118 in) fan and scaled IP compressor of the 777-200X/300X Trent 8104 technology demonstrator derived from the Boeing 777's Trent 800 , and the Airbus A340-500/600's Trent ...
The particular take-off distance required may be shorter than the available runway length. In this case a lower thrust may be used. Lower thrust settings increase engine life and reduce maintenance costs. The take-off thrust available from a civil engine is a constant value up to a particular ambient temperature.

These vary with speed, so the results are typically plotted on a 2-dimensional graph. In almost all cases the graph forms a U-shape, due to the two main components of drag. The L/D may be calculated using computational fluid dynamics or computer simulation. It is measured empirically by testing in a wind tunnel or in free flight test. [1] [2] [3]
The takeoff decision speed V 1 is the fastest speed at which the pilot must take the first actions to reject the takeoff (e.g. reduce thrust, apply brakes, deploy speed brakes). At speeds below V 1 the aircraft can be brought to a halt before the end of the runway. At V 1 and above, the pilot should continue the takeoff even if an emergency is ...
