Weight and stability is a crucial point to the security of flight. An obese airplane, or one whose middle of gravity is outdoors the allowable limits, is inefficient and unsafe to fly. The accountability for correct weight and stability keep watch over starts with the engineers and architects, and extends to the pilot and mechanic who flies and keeps the plane. This Federal Aviation management (FAA) e-book addresses this safety-crucial subject and in learning this instruction manual, pilots and Aviation upkeep Technicians (AMTs) will achieve the required wisdom with reference to plane weight and stability, in education for the FAA wisdom examination in addition to secure flight and upkeep operations.

Basic airplane weight and stability regulate ideas and tactics for the training, and the particular weighing of an plane commence the dialogue, together with the equipment of choosing the positioning of the empty weight heart of gravity. Loading computations with loading graphs and tables of weight and second indexes persist with, together with directions on opting for the burden and middle of gravity adjustments as a result of upkeep and changes or removing and set up of apparatus. Chapters are devoted to light-sport airplane, single-engine airplane, multi-engine plane, and commuter and massive plane, in addition to helicopter weight and stability regulate and identifying lateral CG. additionally integrated are examples of fixing weight and stability difficulties utilizing a handheld digital calculator, E6-B flight desktop, and a committed digital flight computer.

This 2016 variation displays the most recent aviation strategies, gear, concepts, laws, and is a key reference within the FAA Airman Certification criteria (ACS). Illustrated all through with distinct, full-color drawings, and contains a word list and index.

HueyCobra Gunships

The Bell Huey Cobra used to be the first actual purpose-designed helicopter gunship to turn into operational and to determine strive against. Designed within the mid-1960s as an "interim resolution" for an armed escort and close-support weapon to aid the USA military within the Vietnam battle, it really is nonetheless being synthetic and stronger within the twenty first century, making it a hit a ways past the wildest goals of its creators.

Example text

The actual adjustments to level the aircraft using load cells are made with the jacks. When weighing from the wheels, leveling is normally done by adjusting the air pressure in the nose wheel shock strut. Safety Considerations Special precautions must be taken when raising an aircraft on jacks. 1. Stress plates must be installed under the jack pads if the manufacturer specifies them. 2. If anyone is required to be in the aircraft while it is being jacked, there must be no movement. 3. The jacks must be straight under the jack pads before beginning to raise the aircraft.

Typical loading graph. indd 3 3/14/07 10:26:36 PM Compute Weight and Balance Using the Loading Graph To compute the weight and balance using the loading graph in Figure 4-6, make a loading schedule chart like the one in Figure 4-7. In Figure 4-6, follow the horizontal line for 300 pounds load weight to the right until it intersects the diagonal line for pilot and front passenger. From this point, drop a line vertically to the load moment index along the bottom to determine the load moment for the front seat occupants.

This is distance (D). The weight of the nose wheel (F) is 340 pounds, and the distance between main wheels and nose wheel (L) is 78 inches. The total weight of the airplane (W) is 2,006 pounds. Figure 3-6. The datum is aft of the main wheels at the wing trailing edge. The location of the CG may be determined by using this formula: Figure 3-5. The datum is 100 inches forward of the wing root leading edge. 2 inches forward of the datum. 2 inches forward of the main wheels, exactly the same location as it was when it was measured from other datum locations.
