The Performance

Today I will speak of what is known as aviation performance of an aircraft. This is a very interesting but in turn explain complex, especially staff "no aircraft, so I'll try to put it in the most simple objects can to make it easy to understand for everyone.

could say that the performance is the set of mathematical parameters that define the way you have to fly an airplane. Let me explain. All we ever heard, or experienced, the history of that aircraft had to throw fuel to save weight and to land, or much more high-profile cases as the landing of the aircraft carried passengers because overweight and can not take off.

The vast majority of aircraft operations are based on weight. Obviously the weight on an airplane is important, because it depends on factors such as takeoff speeds, runway length required, the cruising altitude to which we fly, or fuel consumption. All these factors are specified in the tables of performance of each airplane.

Each aircraft has its weight limits. Thus, in the section on specific gravity of an aircraft we can find the maximum takeoff weight, maximum weight of load, ramp weight, maximum landing weight, maximum weight-load, etc.

There is a direct relationship between the weight of an airplane and the speed required to perform a maneuver ie for every maneuver there is a speed determined by the weight of the aircraft at that time. For example, takeoff speeds are calculated, among other factors to be discussed later, depending on the weight. It is easy to understand that the higher weight, higher airspeed needed to sustain a plane in the air. The same applies to the stall speed (the speed at which the plane "left" to fly). The greater weight loss faster.

relationship between available power and temperature

However, the result of flying a plane within a certain speed and weight is altered by three other factors taken into account too, which are temperature, altitude and air pressure that can determine for example, that an airplane can off or not.

Nobody scared because now I will not go into topics of physics to explain this. Just hold on to that higher temperature and altitude of an airport, the greater the speed needed for takeoff or landing a plane, and consequently, the higher the required runway length.

The engine power is also affected by these factors of altitude and temperature. The higher the temperature and altitude lower the available power in the engines. The reason is that a hot air ingested by a turbine at high speeds must not only may damage the internal parts but could cause the compressor stall due to lower air density, which could lead to loss of thrust in that motor.

Applying this to a practical case, we could say that in a very hot day in an airport located high above sea level, a plane may not have enough runway to take off according to their weight. Whereupon, or canceled flight, or remove the weight necessary to take the airplane within safe operating limits. This is the reason why Barajas tracks or those in very warm areas such as Andalusia and the Canary Islands have such long tracks.

required runway length may vary depending on the temp.

As the takeoffs and landings are subject to certain parameters, so is the climb after takeoff. The promotions are regulated by a minimum slope aircraft safety must be able to comply with engine stopped, and sometimes affected by the topography of an airport. For example, Alvedro has two headers, the 04 and 22. The latter heads to a hill, forcing a passenger aircraft to make an immediate left turn after takeoff with a speed limit. With limited aircraft capacity, with a lot of weight or high air temperature, could be the case that could not meet the required speed or the slope given in the case of engine failure, so that aircraft could not take off.

more meters are needed for takeoff, and landing stop

Other factors such as the weather affecting the performance of the aircraft on takeoff or landing. For example, rain, snow, or anything else that might "contaminate" the court penalized the same length required for takeoff. In turn, a contaminated runway braking capability offers less and therefore a greater length of runway needed to land, which can translate into the cancellation of operations because they can not meet the parameters. Nor can we forget that in the takeoff is referred to the length of runway needed to slow and stop if an abortion maneuvering and braking that takes into account the condition of the track, which finally together is what determines the weight and wind, the speed at which we can no longer abort the takeoff decision speed or V1.

As you have noticed, are thousands of factors to take into account the operations of the aircraft, always subject to specific parameters given by tables of performance of aircraft and in any case to the improvisation of the crew.
