Fixed-wing water bombers, also known as air tankers, employ a unique method called the scooping method to gather water for firefighting purposes. This technique involves scooping water from bodies of water such as lakes, reservoirs, and even rivers while the aircraft remains in flight. To facilitate this process, fixed-wing water bombers are equipped with specialized floats attached to their undercarriage.
The primary role of these floats is to enable the aircraft to land on the water surface safely and scoop water effectively. They are designed to provide buoyancy and stability to the aircraft during the scooping process. The floats allow the water bomber to skim across the surface of the water without submerging the aircraft or causing damage to its structure.
B. How the scooping method is executed
When a fixed-wing water bomber needs to refill its water supply, it will begin by identifying a suitable body of water nearby. The aircraft then descends at a gradual angle and approaches the water surface while maintaining a safe altitude. As it reaches the desired location, the pilot activates the scooping mechanism.
The scooping mechanism typically consists of a scoop or a series of scoops located beneath the floats. These scoops are designed to extend downwards into the water as the aircraft skims across the surface. As the scoops submerge, they fill up with water before retracting back into the aircraft.
Once the water is collected inside the aircraft, it is stored in internal tanks specifically designed to carry large volumes of water. The pilot then disengages the scooping mechanism, retracts the floats, and the aircraft resumes normal flight operations. The collected water can be dropped onto the fire as a targeted aerial attack or transported to a base camp for further use.
The scooping method is a rapid and efficient way for fixed-wing water bombers to replenish their water supply during firefighting operations. It allows for multiple scoops in quick succession, reducing turnaround time and enabling the aircraft to return to the fire zone promptly. However, it is crucial for pilots to exercise caution and adhere to safety protocols when performing water scooping maneuvers to ensure the smooth and seamless execution of the technique.
