In navigation, the heading of a vessel or aircraft is the compass direction in which the craft's bow or nose is pointed. Note that the heading may not necessarily be the direction that the vehicle actually travels, which is known as its course. [a] Any difference between the heading and course is due to the motion of the underlying medium, the ...
In ballistics and flight dynamics, axes conventions are standardized ways of establishing the location and orientation of coordinate axes for use as a frame of reference. Mobile objects are normally tracked from an external frame considered fixed. Other frames can be defined on those mobile objects to deal with relative positions for other objects.
VOR is a more sophisticated system, and is still the primary air navigation system established for aircraft flying under IFR in those countries with many navigational aids. In this system, a beacon emits a specially modulated signal which consists of two sine waves which are out of phase. The phase difference corresponds to the actual bearing ...
Flight dynamics is the science of air vehicle orientation and control in three dimensions. 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 ...
North Atlantic Tracks for the westbound crossing of February 24, 2017, with the new RLAT Tracks shown in blue. The North Atlantic Tracks, officially titled the North Atlantic Organised Track System (NAT-OTS), are a structured set of transatlantic flight routes that stretch from eastern North America to western Europe across the Atlantic Ocean, within the North Atlantic airspace region.
An attitude and heading reference system (AHRS) consists of sensors on three axes that provide attitude information for aircraft, including roll, pitch, and yaw.These are sometimes referred to as MARG (Magnetic, Angular Rate, and Gravity) [1] sensors and consist of either solid-state or microelectromechanical systems (MEMS) gyroscopes, accelerometers and magnetometers.
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. [1][2][3] The path that a vessel follows is called a track or, in the case of aircraft ...
The wind triangle is a vector diagram, with three vectors. The air vector represents the motion of the aircraft through the airmass. It is described by true airspeed and true heading. The wind vector represents the motion of the airmass over the ground. It is described by wind speed and the inverse of wind direction.
