Center Of Gravity Of An Aircraft
The center of gravity (CG) of an aircraft is the point over which the aircraft would balance. Its position is calculated after supporting the aircraft on at least two sets of weighing scales or load cells and noting the weight shown on each set of scales or load cells. The center of gravity affects the stability of the aircraft. To ensure the aircraft is safe to fly, the center of gravity must fall within specified limits established by the aircraft manufacturer. Terminology ;Ballast: Ballast is removable or permanently installed weight in an aircraft used to bring the center of gravity into the allowable range. ;Center-of-Gravity Limits: Center of gravity (CG) limits are specified longitudinal (forward and aft) and/or lateral (left and right) limits within which the aircraft's center of gravity must be located during flight. The CG limits are indicated in the airplane flight manual. The area between the limits is called the ''CG range'' of the aircraft. ;Weight and Balanc ...

Weighing Scale
A scale or balance is a device used to measure weight or mass. These are also known as mass scales, weight scales, mass balances, and weight balances. The traditional scale consists of two plates or bowls suspended at equal distances from a fulcrum. One plate holds an object of unknown mass (or weight), while known masses are added to the other plate until static equilibrium is achieved and the plates level off, which happens when the masses on the two plates are equal. The perfect scale rests at neutral. A spring scale will make use of a spring of known stiffness to determine mass (or weight). Suspending a certain mass will extend the spring by a certain amount depending on the spring's stiffness (or spring constant). The heavier the object, the more the spring stretches, as described in Hooke's law. Other types of scales making use of different physical principles also exist. Some scales can be calibrated to read in units of force (weight) such as newtons instead of un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Weight Distribution
Weight distribution is the apportioning of weight within a vehicle, especially cars, airplanes, and trains. Typically, it is written in the form ''x''/''y'', where ''x'' is the percentage of weight in the front, and ''y'' is the percentage in the back. In a vehicle which relies on gravity in some way, weight distribution directly affects a variety of vehicle characteristics, including handling, acceleration, traction, and component life. For this reason weight distribution varies with the vehicle's intended usage. For example, a drag car maximizes traction at the rear axle while countering the reactionary pitch-up torque. It generates this counter-torque by placing a small amount of counterweight at a great distance forward of the rear axle. In the airline industry, load balancing is used to evenly distribute the weight of passengers, cargo, and fuel throughout an aircraft, so as to keep the aircraft's center of gravity close to its center of pressure to avoid losing ...

De Havilland Canada DHC-3 Otter
The de Havilland Canada DHC-3 Otter is a single-engined, high-wing, propeller-driven, short take-off and landing (STOL) aircraft developed by de Havilland Canada. It was conceived to be capable of performing the same roles as the earlier and highly successful Beaver, including as a bush plane, but is overall a larger aircraft. Design and development The rugged single-engined, high-wing, propeller-driven DHC-3 Otter was conceived in January 1951 by de Havilland Canada as a larger, more powerful version of its highly successful DHC2 Beaver STOL utility transport. Dubbed the "King Beaver" during design, it would be the veritable "one-ton truck" to the Beaver's "half-ton" role. The Otter received Canadian certification in November 1952 and entered production shortly thereafter. Using the same overall configuration as the Beaver, the new, much heavier design incorporated a longer fuselage, greater-span wing, and cruciform tail. Seating in the main cabin expanded from six to 10 or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crocodile
Crocodiles (family Crocodylidae) or true crocodiles are large semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. The term crocodile is sometimes used even more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans (family Alligatoridae), the gharial and false gharial (family Gavialidae) among other extinct taxa. Although they appear similar, crocodiles, alligators and the gharial belong to separate biological families. The gharial, with its narrow snout, is easier to distinguish, while morphological differences are more difficult to spot in crocodiles and alligators. The most obvious external differences are visible in the head, with crocodiles having narrower and longer heads, with a more V-shaped than a U-shaped snout compared to alligators and caimans. Another obvious trait is that the upper and lower jaws of the crocodiles are the same width, and the teeth in the lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2010 Filair Let L-410 Crash
On 25 August 2010, a Let L-410 Turbolet passenger aircraft of Filair crashed on approach to Bandundu Airport in the Democratic Republic of the Congo, killing all but one of the 21 people on board. The accident was reportedly the result of the occupants rushing to the front of the aircraft to escape from a crocodile smuggled on board by one of the passengers. The move compromised the aircraft's balance to the point that control of the aircraft was lost. Accident The aircraft was operating a round-robin domestic flight from Kinshasa, Democratic Republic of the Congo, stopping at Kiri, Bokoro, Semendwa and Bandundu. At 13:00 local time (12:00 UTC), while on final approach to Bandundu Airport, the aircraft crashed into a house approximately short of the runway. According to most sources, no one was injured on the ground. 19 people were killed instantaneously, with two survivors being taken to hospital- one of whom later died from their injuries. Of the 21 people on board, only ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotation (aeronautics)
In aviation, rotation refers to the action of applying back pressure to a control device, such as a yoke, side-stick or centre stick, to lift the nose wheel off the ground during takeoff. The aircraft rotates around its lateral axis. Rotation is begun at the speed known as VR. Rotation at the correct speed and to the correct angle is important for safety reasons and to decrease takeoff distance. After rotation, the aircraft continues to accelerate until it reaches its liftoff speed VLO, at which point it leaves the runway. Over-rotation can cause a tailstrike, which can damage the underside of the tail unless prevented by a protection device such as a tailskid or tail bumper. A certification test is required to show that a new aircraft design will still take off safely with the tail dragging on the runway. Using a higher VR will increase tail clearance and reduce the probability of tailstrike. Description Rotation applies to tricycle gear aircraft rather than those with conv ...

Challenger 600
The Bombardier Challenger 600 series is a family of business jets developed by Canadair after a Bill Lear concept, and then produced from 1986 by its new owner, Bombardier Aerospace. At the end of 1975, Canadair began funding the development of LearStar 600, and then bought the design for a wide-cabin business jet in April 1976. On 29 October, the programme was launched, backed by the Canadian federal government, and designed to comply with new FAR part 25 standards. In March 1977, it was renamed the Challenger 600 after Bill Lear was phased out, and the original conventional tail was changed for a T-tail among other developments. The first prototype was rolled out on 25 May 1978, and performed its maiden flight on 8 November. The flight test program saw a deadly crash on 3 April 1980, but Transport Canada approved the CL-600 type certification on 10 August 1980. In 1986, Canadair was close to bankruptcy and was bought by Bombardier. The jet was later stretched into the B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
