Landing is the process by which a flying device returns to earth. It has some peculiarities to take into account depending on the aircraft in question, the peculiarities that must be addressed to avoid accidents. Landing can also refer to the process by which modules that were in space return to the ground with the crew; In the event that the descent is made at sea, the correct term to use is "splashdown".
The landing process is generally considered critical, in the same way as the take-off process. That is why a suitable surface is required to ensure the safety of the aircraft. They usually have signs with lights so this procedure can be done at night. In general, pilots receive assistance from a control tower and this is in charge of the way in which takeoffs and landings are organized; in these cases, synchronization is central, as well as the reduction of waiting times.
In general, the landing is carried out according to a plan. The aircraft in question will land at the location previously determined after its flight plan. If complications arise (with a severe storm or mechanical failure), the pilot may need to make an out-of-plane landing (that is, it was unplanned).
This is the case when you decide to land at an airport other than the one provided, to name one possibility. When the decision to change the plan must be made urgently due to the safety of passengers and crew at risk, we speak of a forced or emergency landing.
Lo que puede ocurrir es que un aterrizaje de emergencia o también llamado forzado, antes de que ocurra una contingencia en el medio del vuelo. Por ejemplo, se detecta un mal funcionamiento técnico que podría poner en riesgo las vidas de los pasajeros y la tripulación, por lo que el piloto debería aterrizar donde pueda, si es mejor en cualquier otra pista incluida en la hoja de ruta, pero debería hacerlo donde él puede, tomando las precauciones del caso si es posible, tal es el caso de hacerlo en un lugar abierto y despoblado.
