C is for Center of Gravity
There were aspects of firefighting that Chief Blade Ranger knew that ground wildfire personal would never understand. On a bad burn, the helicopter would hear the dozers and wildland rigs complain about the frame-breaking work. As hard as their work was, Blade knew that the physical strain that a tanker underwent during a drop pushed those aircraft to their limits. Most of the time experience and physical stamina would see an aircraft through…but the moments that those failed the results were disastrous.
A single miss calculation about the wind or a change of wind could easily translate into having your parts scatter unceremoniously across the rocks. A single lap of judgment could turn you into a burning pyre. A single hairline fracture could cause your wings to be ripped from your frame during a drop. There were just so many things that could go wrong, and such a high cost when they did.
It was the knowledge that both he and his team had chosen a career where a single error could land them a place on the wall, that proved to be the driving force for Blade's existence. He pushed himself hard, practicing maneuvers with different loads and different winds. He practiced, and he took notes which he used to help those who served under him push their limits but not cross them. Then, he drilled that knowledge into their muscle memory with a level of tenacity and precision that only someone who had looked death in the face and survived would ever attempt.
"Try it again, Champ."
Blade had seen what happened when an aircraft misjudged the change in their center of gravity when they made a drop in the past. And that is why he was so determined to make sure that the people who worked under him were given plenty of opportunities to learn the limits of their hulls under safe conditions and his watchful eyes. They may grumble, like the green as river birch plane in front of him, but Blade knew that when slag really hit the fan, every vehicle he trained would eventually appreciate all the practice they had put in.
Term – Center of Gravity – The center of gravity refers to the location in an object where the amount of mass is the same in all directions. It is important for helicopter and aircraft pilots to understand where the center of gravity for their aircraft is because that is the point where that aircraft pivots in space. The rapid change in an aircraft's center of gravity after they drop their load is one of the factors that make areal firefighting one of the most dangerous types of flying. It takes a lot of practice and instinct for pilots to learn how their aircraft's behavior shifts as before, during, and after a retardant drop.
