Title: Detachable floating equipment

Description:
FIELD OF THE INVENTION 
     The present invention relates to at least one detachable floating bag to deploy on impact with the water and enable stabilization of the aircraft for the prevention of the aircraft from sinking, until the surviving passengers and crew members is been rescued. 
     BACKGROUND OF THE INVENTION 
     In the recent years, the world has witnessed several horrific airline accidents resulting in hundreds of deaths. When an airplane crashes into the ocean, there is no time for the passengers and crew to escape before the plane sinks, drowning everyone on the plane. When the plane breaks into sections as it strikes the water, the lives of some of the passengers may be spared if the individual sections did not sink quickly. 
     Moreover, aircrafts technical faults can only be fixed when the aircraft is not in a working position, once the aircrafts take off in order to complete it desirable ride from one place to another it becomes very difficult for any of the engineer to maneuver any default in any machinery involved in the construction of the aircraft. 
     However, parachutes have been used in connection with aircraft to retard the speed of the aircraft during landing procedures. However, it would be highly desirable to have aircraft safety apparatus which would assist the maneuverability of disabled aircraft and would assist in emergency landing operations. In this regard, it would be desirable where an airplane or other aircraft that loses power due to some technical fault could do secure landing, and remain maneuverable during such emergency landing procedures to avoid disasters, thereby protecting lives and equipment. 
     Therefore, there remains a need to overcome above mentioned problems and our invention resolve this entire problem. 
     SUMMARY OF THE INVENTION 
     The main objective of the present invention is to overcome the limitations of the prior arts by providing at least one detachable floating bag, to support different sections of the aircraft. In a situation of an aircraft failure, the at least one detachable floating bag is designed to detonate from each side of the aircraft in order to keep the aircraft in the upright position and protect survivors from drowning until they are rescued. The at least one detachable floating bag is self-inflating, like an airbags in other vehicles, so they do not take up valuable space in the airplane. The at least one detachable floating bag is there to provide a new safety feature for an aircraft, in case of an emergency landing of the aircraft over a water body. The self-inflating at least one detachable floating bag stabilizes a crashed aircraft by maintaining its upright position and thus prevents the aircraft from sinking &amp; saving many lives on the aircraft before being rescued and further enable at least one light attachment which enables visual identification of the detachable floating bag and a persons involved in the emergency landing of the aircraft thereby, makes the aircraft easily visible and also, easy to locate. Herein, the aircraft have at least one chamber with an opening, wherein the at least one chamber is located on at least one side of the aircraft. Also, the at least one chamber with an opening is enabled to receive at least one detachable floating bag in flattened state. In a situation, when there is a technical default in the aircraft and the aircraft is enabled to do an emergency landing on a water body then in such situation, as soon as the aircraft comes in contact with water, the water sensors attached to the aircraft get triggered which further enables a reaction that produces nitrogen gas. This nitrogen gas produced is caused by an electrical stimulus, possibly generated by the water sensor which further helps triggering out the at least one detachable floating bag. The at least one detachable floating bag is enabled to come out from an opening of at least one chamber as soon as the water sensor gets the signal of the emergency landing and further comes in contact with water. The at least one detachable floating bag lined up with at least one chemical compound when comes in contact with the water leads to a chemical reaction to produces a buoyant gas (hydrogen) which leads to inflation of at least one detachable floating bag and also enables to keep the aircraft in the upright position for protecting the survivors from drowning until they are been rescued and further enable at least one light attachment which enables visual identification of the detachable floating bag and a persons involved in the emergency landing of the aircraft thereby makes the aircraft easy visible and easy to locate. 
     Also, in the present invention the aircraft includes a monitor utilizing a network of the sensors, wherein the sensors are coupled to at least one detachable floating bag, wherein the sensors enable sending signal to those onboard the aircraft so as to intimate with the current status of the inflated at least one detachable floating bag. By use of the monitor the observer determines whether at least one detachable floating bag is activated properly and is holding gas properly. In the event that the pressure begins to drop at a level deemed that may no longer support the weight of the aircraft upon the water, then the monitor signals an alarm to indicate the aircraft is losing or has lost enough gas or buoyancy to stay above the water. The at least one detachable floating bag also include an automatic jettisoning of the aircraft data recorder in order to assist in the recovery of valuable aircraft data in the event of the emergency landing.
