Currently there are many options for the use of drones in rescue and lifeguard services and different types and brands of drones.
Through these aircraft that are regulated by the AESA (State Agency for Aviation Safety), activities such as:
Search and rescue
In order to use them, you must have a drone pilot license issued by AESA and also an authorization for their use, which depending on the characteristics of the place may entail different restrictions.
Drones are capable of filming with different types of cameras (thermal cameras, precision cameras, submersible cameras, etc.) which gives them a lot of versatility.
They are prepared for cargo transfer and release, a drone weighing less than 10 kg can carry loads of up to 8 kg depending on the type of drone. This feature is what allows them to move and drop some type of rescue item on a possible victim at sea. Normally the transport and release system is usually an accessory that is added to the drone.
One of the problems with drones with conventional batteries is that their autonomy is very limited. Conventional drones typically have a battery life range of 10-15 minutes. Currently, tests are being carried out with combinations of conventional batteries + hydrogen cell, considerably increasing the autonomy, which can reach 3 hours. These teams are still in the development phase.
Drones with GPS allow controlled flights and also have advantages when taking off and landing that facilitate the pilot's task. With this type of Drones, pre-established routes (flight plan) can be loaded so that the aircraft executes them automatically. They also have very useful "return home" functions if you lose sight of your aircraft. For the return home function, the drone saves the point from which it took off to return in case the pilot indicates so.
