The center of gravity (CG) of an aircraft is the point over which the aircraft would balance. [1] 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.
The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as pitch, roll and yaw. These are collectively known as aircraft attitude , often principally relative to the atmospheric frame in normal flight, but also relative to terrain during takeoff or landing ...
The airspeed at which the aircraft stalls varies with the weight of the aircraft, the load factor, the center of gravity of the aircraft and other factors. However, the aircraft normally stalls at the same critical angle of attack, unless icing conditions prevail. The critical or stalling angle of attack is typically around 15° - 18° for many ...
Heading and track (A to B) 1 - True North 2 - Heading, the direction the vessel is "pointing towards" 3 - Magnetic north, which differs from true north by the magnetic variation. 4 - Compass north, including a two-part error; the magnetic variation (6) and the ship's own magnetic field (5) 5 - Magnetic deviation, caused by vessel's magnetic field.
The flight plan is generally determined on the ground, before departure either by the pilot for smaller aircraft or a professional dispatcher for airliners. It is entered into the FMS either by typing it in, selecting it from a saved library of common routes (Company Routes) or via an ACARS datalink with the airline dispatch center.
Instruments used to plot a course on a nautical chart. In navigation, the course of a watercraft or aircraft is the cardinal direction in which the craft is to be steered.The course is to be distinguished from the heading, which is the direction where the watercraft's bow or the aircraft's nose is pointed.
The Nimitz-class aircraft carrier USS Theodore Roosevelt (CVN-71) is the group's current flagship. Other group units include Carrier Air Wing 11 , the Ticonderoga -class cruiser USS Lake Erie (CG-70) , and the Arleigh Burke -class destroyer's USS John S. McCain (DDG-56) , USS Halsey (DDG-97) , and the USS Daniel Inouye (DDG-118) .
Modern United States Navy aircraft carrier air operations include the operation of fixed-wing and rotary aircraft on and around an aircraft carrier for performance of combat or noncombat missions. The flight operations are highly evolved, based on experiences dating back to 1922 with USS Langley .
